CLASS A Digital equipment meant for light industrial use Less restrictive emissions requirement: less than 40 dB V/m at 10 m (40 dB relative to 1 V/m) or 300 V/m CLASS B Digital equipment meant for home use More restrictive emissions requirement: 30 dB V/m at 10 m or 100 V/m These limits apply over the range of 30-230 MHz. The limits are 7 dB higher for frequencies above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit-based systems at frequencies above 300 MHz are generally well below background noise levels. The CPU card, I/O cards, and backplane in the Smart Star embedded control system have been tested and were found to be in conformity with the following applicable immunity and emission standards as described in Table 3. Table 3.

Emissions The CE-compliant Smart Star boards meet the following emission standards when used with a Smart Star embedded control system that contains a Rev. C or higher version of the Rabbit 2000 microprocessor with its spectrum spreader turned on and set to the normal mode. This microprocessor is used in all Smart Star CPU boards that carry the CE mark. * EN55022:1998 Class A * FCC Part 15 Class A NOTE: The Smart Star embedded control system satisfied the Class A limits but not the Class B limits. Such equipment need not be restricted in its sale, but the following warning must be included in the instructions for its use. Warning This is a class A product. In a domestic environment this product may cause radio interference, in which case the user may be required to take adequate measures. Additional shielding or filtering may be needed to meet Class B emissions standards. 14 Smart Star (SR9000) 1.5.1 Design Guidelines Note the following requirements for incorporating a Smart Star embedded control system into your application to comply with CE requirements. General * The power supply provided with the Tool Kit is for development purposes only. It is the customer's responsibility to provide a CE-compliant power supply for the end-product application. * When connecting the Smart Star embedded control system to outdoor cables, the customer is responsible for providing CE-approved surge/lighting protection. * Rabbit recommends placing digital I/O or analog cables that are 3 m or longer in a metal conduit to assist in maintaining CE compliance and to conform to good cable design practices. * When installing or servicing the Smart Star embedded control system, it is the responsibility of the end-user to use proper ESD precautions to prevent ESD damage to the Smart Star. Safety * All inputs and outputs to and from the Smart Star embedded control system must not be connected to voltages exceeding SELV levels (42.4 V AC peak, or 60 V DC). * The lithium backup battery circuit on the CPU card in the Smart Star embedded control system has been designed to protect the battery from hazardous conditions such as reverse charging and excessive current flows. Do not disable the safety features of the design. 1.5.2 Interfacing the Smart Star to Other Devices Since Smart Star embedded control systems are designed to be connected to other devices, good EMC practices should be followed to ensure compliance. CE compliance is ultimately the responsibility of the integrator.

Apply power. Plug the power supply in to a nearby outlet. The CPU Card is now ready to be used. NOTE: A hardware RESET is accomplished by unplugging the power supply, then plugging it back in. To power down the SmartStar, unplug the power supply. You should disconnect power before making any circuit adjustments or changing any connections to the SmartStar. User's Manual 21 CPU/BACKPLANE CPU/BACKPLANE 2.4 Installing Dynamic C If you have not yet installed Dynamic C version 7.06P3 (or a later version), do so now by inserting the Dynamic C CD from the Smart Star Tool Kit in your PC's CD-ROM drive. The CD will auto-install unless you have disabled auto-install on your PC. If the CD does not auto-install, click Start > Run from the Windows Start button and browse for the setup.exe file on your CD drive. Click OK to begin the installation once you have selected the setup.exe file. The online documentation is installed along with Dynamic C, and an icon for the documentation menu is placed on the workstation's desktop. Double-click this icon to reach the menu. If the icon is missing, create a new desktop icon that points to default.htm in the docs folder, found in the Dynamic C installation folder. The latest versions of all documents are always available for free, unregistered download from our Web sites as well. The Dynamic C User's Manual provides detailed instructions for the installation of Dynamic C and any future upgrades. NOTE: If you have an earlier version of Dynamic C already installed, the default installation of the later version will be in a different folder, and a separate icon will appear on your desktop. 22 Smart Star (SR9000) 2.5 Starting Dynamic C Once the CPU Card is installed and connected as described above, start Dynamic C by double-clicking on the Dynamic C icon or by double-clicking on dcrab_XXXX.exe in the Dynamic C root directory, where XXXX are version-specific characters. Dynamic C defaults to using the serial port on your PC that you specified during installation. If the port setting is correct, Dynamic C should detect the CPU Card and go through a sequence of steps to cold-boot the CPU Card and to compile the BIOS. (Some versions of Dynamic C will not do the initial BIOS compile and load until the first time you compile a program.) If you receive the message No Rabbit Processor Detected, the programming cable may be connected to the wrong COM port, a connection may be faulty, or the target system may not be powered up. First, check both ends of the programming cable to ensure that it is firmly plugged into the PC and the programming port. If there are no faults with the hardware, select a different COM port within Dynamic C. From the Options menu, select Communications. Select another COM port from the list, then click OK. Press User's Manual 23 CPU/BACKPLANE CPU/BACKPLANE 2.6 PONG.C You are now ready to test your set-up by running a sample program. Find the file PONG.C, which is in the Dynamic C SAMPLES folder. To run the program, open it with the File menu (if it is not still open), compile it using the Compile menu, and then run it by selecting Run in the Run menu. The STDIO window will open and will display a small square bouncing around in a box. This program does not test the serial ports on the CPU Card, but does ensure that the CPU is basically functional. 24 Smart Star (SR9000) 2.7 Installing I/O Cards 1.

Smart Star Control System Power Supply Schematic A capacitor provides surge current protection for the voltage regulator, and allows the external power supply to be located some distance away from the Smart Star control system. A switching power regulator is used. The +RAW input voltage may range from 9 V to 30 V (15 V to 30 V you plan to use a D/A Converter Card). The backplane has inputs for two separate power supplies on header J1, +RAW and V_USER. The +RAW power supply goes to the switching power regulator, which outputs the +5 V DC used by the CPU Card and by the I/O cards plugged into the backplane. The V_USER connection allows a different voltage to be available on the I/O cards for future development. NOTE: Always connect V_USER to +RAW with a jumper wire between terminals 1 and 2 on header J1 for the development activities described in the Smart Star manuals. 28 Smart Star (SR9000) Figure 7 shows how the power supplies are distributed on the backplane and on the CPU Card.

User's Manual 31 CPU/BACKPLANE CPU/BACKPLANE 3.2 Smart Star CPU Card Features 3.2.1 Serial Communication The CPU Card has one screw terminal header for RS-232/RS-485 serial communication (J3) and one RJ-45 Ethernet jack (J7, SR9150 only). The RJ-12 jack, J6, is reserved for future use and therefore has no signals. The pinouts are shown in Figure 10.

Smart Star CPU Card Serial Pinout The factory default for the CPU Card is one RS-232 (3-wire) and one RS-485 serial channel, corresponding to Mode 0 in Figure 10. The other modes shown in Figure 10 are set in software via the Dynamic C serMode function call (see Section 4.5, "Serial Communication Calls"). 3.2.1.1 RS-232 The CPU Card's RS-232 serial channel is connected to an RS-232 transceiver. The transceiver provides the voltage output, slew rate, and input voltage immunity required to meet the RS-232 serial communication protocol. Basically, the chip translates the Rabbit 2000's 0 V to +Vcc signals to RS-232 signal levels. Note that the polarity is reversed in an RS-232 circuit so that +5 V is output as approximately -10 V and 0 V is output as approximately +10 V. The transceiver also provides the proper line loading for reliable communication. The maximum baud rate is 115,200 bps. RS-232 can be used effectively at this baud rate for distances up to 15 m. The Rabbit 2000 serial port C TXD and RXD signals are presented either as RS-232 TX and RX or as RTS/CTS handshaking, depending on the mode selected with the Dynamic C function serMode. The RS-232 signals are available on screw terminal header J3. 32 Smart Star (SR9000) TXC 1 RTS 3.2.1.2 RS-485 The CPU Card has one RS-485 serial channel, which is connected to the Rabbit 2000 serial port C through an RS-485 transceiver. The chip's slew rate limiters provide for a maximum baud rate of 250,000 bps, and allows networking over a distance of up to 300 m (or 1000 ft.). The half-duplex communication uses the Rabbit 2000's PD4 pin to control the data enable on the communication line. The RS-485 signals are available on the CPU Card through screw terminal header J3. The Smart Star control system can be used in an RS-485 multidrop network. Connect the 485+ to 485+ and 485- to 485- using single twisted-pair wires on the CPU Card's header J4 as shown in Figure 11.

The programming port uses the Rabbit 2000's Serial Port A for communication. Dynamic C uses the programming port to download and debug programs. The programming port is also used for the following operations. * Cold-boot the Rabbit 2000 on the RabbitCore module after a reset. * Remotely download and debug a program over an Ethernet connection using the RabbitLink EG2110. * Fast copy designated portions of flash memory from one Rabbit-based board (the master) to another (the slave) using the Rabbit Cloning Board. Alternate Uses of the Serial Programming Port All three clocked Serial Port A signals are available as * a synchronous serial port * an asynchronous serial port, with the clock line usable as a general CMOS input The serial programming port may also be used as a serial port via the DIAG connector on the serial programming cable. In addition to Serial Port A, the Rabbit 2000 startup-mode (SMODE0, SMODE1), status, and reset pins are available on the serial programming port. The two startup mode pins determine what happens after a reset--the Rabbit 2000 is either cold-booted or the program begins executing at address 0x0000. The status pin is used by Dynamic C to determine whether a Rabbit microprocessor is present. The status output has three different programmable functions: 1. It can be driven low on the first op code fetch cycle. 2. It can be driven low during an interrupt acknowledge cycle. 3. It can also serve as a general-purpose CMOS output. The /RESET_IN pin is an external input that is used to reset the Rabbit 2000 and the onboard peripheral circuits on the Smart Star. The serial programming port can be used to force a hard reset on the Smart Star by asserting the /RESET_IN signal. Refer to the Rabbit 2000 Microprocessor User's Manual for more information. User's Manual 35 CPU/BACKPLANE CPU/BACKPLANE 3.2.1.4 Ethernet Port (SR9150 only) Figure 13 shows the pinout for the Ethernet port (J2 on the CPU Card). Note that there are two standards for numbering the pins on this connector--the convention used here, and numbering in reverse to that shown. Regardless of the numbering convention followed, the pin positions relative to the spring tab position (located at the bottom of the RJ-45 jack in Figure 13) are always absolute, and the RJ-45 connector will work properly with offthe-shelf Ethernet cables. ETHERNET 1 8 1. 2. 3. 6. E_Tx+ E_Tx E_Rx+ E_Rx RJ-45 Plug RJ-45 Jack Figure 13. RJ-45 Ethernet Port Pinout RJ-45 pinouts are sometimes numbered opposite to the way shown in Figure 13. Two LEDs are placed behind the RJ-45 Ethernet jack, one to indicate an Ethernet link (LNK) and one to indicate Ethernet activity (ACT). Only the CPU LEDs are functional at this time since the RCM LEDs were added for future enhancements to the CPU Card. The transformer/connector assembly ground is connected to the CPU Card digital ground via a 0 resistor "jumper," R43, as shown in Figure 14. RJ-45 Ethernet Plug R43 Board Ground Chassis Ground Figure 14. Isolation Resistor R43 The factory default is for the 0 resistor "jumper" at R43 to be installed. In high-noise environments, remove R43 and ground the transformer/connector assembly directly through the chassis ground. This will be especially helpful to minimize ESD and/or EMI problems. 36 Smart Star (SR9000) 3.3 Programming Cable The programming cable is used to connect the programming port of the Smart Star CPU Card to a PC serial COM port. The programming cable converts the RS-232 voltage levels used by the PC serial port to the TTL voltage levels used by the Rabbit 2000. When the PROG connector on the programming cable is connected to the CPU Card's programming header, programs can be downloaded and debugged over the serial interface. The DIAG connector of the programming cable may be used on the CPU Card's programming header with the Smart Star operating in the Run Mode. This allows the programming port to be used as a regular serial port. 3.3.1 Changing Between Program Mode and Run Mode The Smart Star is automatically in Program Mode when the PROG connector on the programming cable is attached to the CPU Card, and is automatically in Run Mode when no programming cable is attached. When the Rabbit 2000 is reset, the operating mode is determined by the status of the SMODE pins. When the programming cable's PROG connector is attached, the SMODE pins are pulled high, placing the Rabbit 2000 in the Program Mode. When the programming cable's PROG connector is not attached, the SMODE pins are pulled low, causing the Rabbit 2000 to operate in the Run Mode.

Standard CPU Cards come with 128K of SRAM. 3.3.2.2 Flash EPROM The Smart Star CPU Card are also designed to accept 128K to a total of 512K of flash memory packaged in a TSOP case. The CPU cards come with two 256K flash memory chips. NOTE: Rabbit recommends that any customer applications should not be constrained by the sector size of the flash memory since it may be necessary to change the sector size in the future. A Flash Memory Bank Select jumper configuration option based on 0 surface-mounted resistors exists at header JP5 on the CPU Card. This option, used in conjunction with some configuration macros, allows Dynamic C to compile two different co-resident programs for the upper and lower halves of the 256K flash in such a way that both programs start at logical address 0000. This is useful for applications that require a resident download manager and a separate downloaded program. See Technical Note 218, Implementing a Serial Download Manager for a 256K Flash, for details. 38 Smart Star (SR9000) 3.3.3 Other Connectors The connectors labeled J4 and J5 in Figure 16 are reserved for future use and should not be used in customer applications at this time.

A built-in clock doubler allows half-frequency crystals to be used to reduce radiated emissions. The 22.1 MHz frequency is generated using an 11.0592 MHz crystal. The clock doubler is disabled automatically in the BIOS for crystals with a frequency above 12.9 MHz. The clock doubler may be disabled if 22.1 MHz clock speeds are not required. Disabling the Rabbit 2000 microprocessor's internal clock doubler will reduce power consumption and further reduce radiated emissions. The clock doubler is disabled with a simple configuration macro as shown below. 1. Select the "Defines" tab from the Dynamic C Options > Project Options menu. 2. Add the line CLOCK_DOUBLED=0 to always disable the clock doubler. The clock doubler is enabled by default, and usually no entry is needed. If you need to specify that the clock doubler is always enabled, add the line CLOCK_DOUBLED=1 to always enable the clock doubler. The clock speed will be doubled as long as the crystal frequency is less than or equal to 26.7264 MHz. 3. Click OK to save the macro. The clock doubler will now remain off whenever you are in the project file where you defined the macro. 3.4.2 Spectrum Spreader Smart Star CPU cards that carry the CE mark have a Rabbit 2000 microprocessor that features a spectrum spreader, which helps to mitigate EMI problems. By default, the spectrum spreader is on automatically for CPU cards that carry the CE mark when used with Dynamic C 7.32 or later versions, but the spectrum spreader may also be turned off or set to a stronger setting. The means for doing so is through a simple configuration macro as shown below. . 1. Select the "Defines" tab from the Dynamic C Options > Project Options menu. 2. Normal spreading is the default, and usually no entry is needed. If you need to specify normal spreading, add the line ENABLE_SPREADER=1 For strong spreading, add the line ENABLE_SPREADER=2 To disable the spectrum spreader, add the line ENABLE_SPREADER=0 NOTE: The strong spectrum-spreading setting is unnecessary for the Smart Star. 3. Click OK to save the macro. The spectrum spreader will now remain off whenever you are in the project file where you defined the macro. There is no spectrum spreader functionality for Smart Star CPU cards that do not carry the CE mark or when using any CPU card with a version of Dynamic C prior to 7.30. User's Manual 41 CPU/BACKPLANE CPU/BACKPLANE 42 Smart Star (SR9000) 4. SOFTWARE Dynamic C is an integrated development system for writing embedded software. It runs on an IBM-compatible PC and is designed for use with Rabbit controllers and other controllers based on the Rabbit microprocessor. Chapter 4 provides the libraries, function calls, and sample programs related to the Smart Star backplane and CPU cards. 4.1 Running Dynamic C You have a choice of doing your software development in the flash memory or in the static RAM included on the Smart Star CPU cards. The flash memory and SRAM options are selected with the Options > Program Options > Compiler menu. The advantage of working in RAM is to save wear on the flash memory, which is limited to about 100,000 write cycles. The disadvantage is that the code and data might not both fit in RAM. NOTE: An application can be developed in RAM, but cannot run standalone from RAM after the programming cable is disconnected. Standalone applications can only run from flash memory. NOTE: Do not depend on the flash memory sector size or type. Due to the volatility of the flash memory market, the Smart Star and Dynamic C were designed to accommodate flash devices with various sector sizes. Developing software with Dynamic C is simple. Users can write, compile, and test C and assembly code without leaving the Dynamic C development environment. Debugging occurs while the application runs on the target. Alternatively, users can compile a program to an image file for later loading. Dynamic C runs on PCs under Windows 95 or later. Programs can be downloaded at baud rates of up to 460,800 bps after the program compiles. User's Manual 43 CPU/BACKPLANE CPU/BACKPLANE Dynamic C has a number of standard features. * Full-feature source and/or assembly-level debugger, no in-circuit emulator required. * Royalty-free TCP/IP stack with source code and most common protocols. * Hundreds of functions in source-code libraries and sample programs: Exceptionally fast support for floating-point arithmetic and transcendental functions. RS-232 and RS-485 serial communication. Analog and digital I/O drivers. I2C, SPI, GPS, encryption, file system. LCD display and keypad drivers. * Powerful language extensions for cooperative or preemptive multitasking * Loader utility program to load binary images into Rabbit targets in the absence of Dynamic C. * Provision for customers to create their own source code libraries and augment on-line help by creating "function description" block comments using a special format for library functions. * Standard debugging features: Breakpoints--Set breakpoints that can disable interrupts. Single-stepping--Step into or over functions at a source or machine code level, C/OS-II aware. Code disassembly--The disassembly window displays addresses, opcodes, mnemonics, and machine cycle times. Switch between debugging at machine-code level and source-code level by simply opening or closing the disassembly window. Watch expressions--Watch expressions are compiled when defined, so complex expressions including function calls may be placed into watch expressions. Watch expressions can be updated with or without stopping program execution. Register window--All processor registers and flags are displayed. The contents of general registers may be modified in the window by the user. Stack window--shows the contents of the top of the stack. Hex memory dump--displays the contents of memory at any address. STDIO window--printf outputs to this window and keyboard input on the host PC can be detected for debugging purposes. printf output may also be sent to a serial port or file. 44 Smart Star (SR9000) 4.1.1 Upgrading Dynamic C 4.1.1.1 Patches and Bug Fixes Dynamic C patches that focus on bug fixes are available from time to time. Check the Web site www.rabbit.com/support/ for the latest patches, workarounds, and bug fixes. The default installation of a patch or bug fix is to install the file in a directory (folder) different from that of the original Dynamic C installation. Rabbit recommends using a different directory so that you can verify the operation of the patch without overwriting the existing Dynamic C installation. If you have made any changes to the BIOS or to libraries, or if you have programs in the old directory (folder), make these same changes to the BIOS or libraries in the new directory containing the patch. Do not simply copy over an entire file since you may overwrite a bug fix. Once you are sure the new patch works entirely to your satisfaction, you may retire the existing installation, but keep it available to handle legacy applications. 4.1.1.2 Upgrades Dynamic C installations are designed for use with the board they are included with, and are included at no charge as part of our low-cost kits. Dynamic C is a complete software development system, but does not include all the Dynamic C features. Rabbit also offers add-on Dynamic C modules containing the popular C/OS-II real-time operating system, as well as PPP, Advanced Encryption Standard (AES), and other select libraries. In addition to the Web-based technical support included at no extra charge, a one-year telephonebased technical support module is also available for purchase. User's Manual 45 CPU/BACKPLANE CPU/BACKPLANE 4.2 Sample Programs Sample programs are provided in the Dynamic C SAMPLES folder. The sample program PONG.C demonstrates the output to the STDIO window. The various directories in the SAMPLES folder contain specific sample programs that illustrate the use of the corresponding Dynamic C libraries. The SAMPLES\SMRTSTAR folder provides sample programs specific to the Smart Star control system. Each sample program has comments that describe the purpose and function of the program. Follow the instructions at the beginning of the sample program. To run a sample program, open it with the File menu (if it is not still open), compile it using the Compile menu, and then run it by selecting Run in the Run menu. The BL2500 must be in Program mode (see Section 3.3, "Programming Cable") and must be connected to a PC using the programming cable as described in Section 2.2, "Connect the Power Supply." More complete information on Dynamic C is provided in the Dynamic C User's Manual. Let's take a look at sample programs for the backplane and the CPU Card in the SMRTSTAR folder. The RS232 directory contains two sample programs to illustrate RS-232 serial communication. * SSTAR232.C--Demonstrates a simple RS-232 loopback using both serial ports C and D. * SSTAR5W.C--Demonstrates simple 5-wire RS-232 communication with flow control. The RS485 directory contains two sample programs to illustrate RS-485 serial communication. * MASTER.C--Demonstrates a simple RS-485 transmission of lower case letters to a slave controller. The slave will send converted upper case letters back to the master controller for display in the STDIO window. Use SLAVE.C to program the slave controller. * SLAVE.C--Demonstrates a simple RS-485 transmission of alphabetic characters to a master controller. The slave will send converted upper case letters back to the master controller for display in the STDIO window. Use MASTER.C to program the master controller. 46 Smart Star (SR9000) 4.3 Dynamic C Libraries One library directory contains software that is unique to the Smart Star. * SMRTSTAR.LIB--This library supports all the functions needed by the Smart Star systems including Digital I/O Cards, Relay Cards, D/A Converter and A/D Converter Cards, and serial communication. Functions dealing with the backplane and the CPU Card are described in this chapter. Functions relevant to the individual I/O cards are described in the chapter specific to the I/O card. Other functions applicable to all devices based on the Rabbit 2000 microprocessor are described in the Dynamic C User's Manual. User's Manual 47 CPU/BACKPLANE CPU/BACKPLANE 4.4 Smart Star Backplane Function Calls 4.4.1 Board Reset void brdResetBus(); Resets all cards on the bus. RETURN VALUE None. 4.4.2 Board Initialization void brdInit(); Initializes slot addressing, disables card enable/disable line, resets card slot bus and LED latch, and turns all LEDS OFF. Call this function at the beginning of the application. RETURN VALUE None. 48 Smart Star (SR9000) 4.5 Serial Communication Calls Library files included with Dynamic C provide a full range of serial communications support. The RS232.LIB library provides a set of circular-buffer-based serial functions. The PACKET.LIB library provides packet-based serial functions where packets can be delimited by the 9th bit, by transmission gaps, or with user-defined special characters. Both libraries provide blocking functions, which do not return until they are finished transmitting or receiving, and nonblocking functions, which must be called repeatedly until they are finished. For more information, see the Dynamic C Function Reference Manual and Technical Note 213, Rabbit 2000 Serial Port Software. Use the following function calls with the Smart Star. int serMode(int mode); User interface to set up serial communication lines for the Smart Star control system.

Note that the TCP/IP feature is available only on the SR9150 CPU Card. 5.1 Ethernet Connections Before proceeding you will need to have the following items. * If you don't have an Ethernet connection, you will need to install a 10Base-T Ethernet card (available from your favorite computer supplier) in your PC. * Two RJ-45 straight-through Ethernet cables and a hub, or an RJ-45 crossover Ethernet cable. The Ethernet cables and Ethernet hub are available from Rabbit in a TCP/IP tool kit. More information is available at www.rabbit.com. 1. Install the CPU Card on the backplane, and connect the power supply and the programming cable as shown in Chapter 2, "Getting Started." 2. Ethernet Connections * If you do not have access to an Ethernet network, use a crossover Ethernet cable to connect the installed CPU Card to a PC that at least has a 10Base-T Ethernet card. * If you have an Ethernet connection, use a straight-through Ethernet cable to establish an Ethernet connection to the installed CPU Card from an Ethernet hub. These connections are shown in Figure 18. SR9150 CPU Card SR9150 CPU Card User's PC Ethernet crossover cable Ethernet cables Hub Direct Connection (network of 2 computers) To additional network elements Direct Connection Using a Hub Figure 18. Ethernet Connections User's Manual 51 CPU/BACKPLANE CPU/BACKPLANE 3. Apply Power Plug in the power supply. The Smart Star is now ready to be used. NOTE: A hardware RESET is accomplished by unplugging the power supply, then plugging it back in. The green LNK light is on the CPU Card is on when the Smart Star is properly connected either to an Ethernet hub or to an active Ethernet card. The orange ACT light flashes each time a packet is received. 52 Smart Star (SR9000) 5.2 TCP/IP Sample Programs We have provided a number of sample programs demonstrating various uses of TCP/IP for networking embedded systems. These programs require that you connect your PC and the Smart Star together on the same network. This network can be a local private network (preferred for initial experimentation and debugging), or a connection via the Internet. 5.2.1 How to Set IP Addresses in the Sample Programs With the introduction of Dynamic C 7.30 we have taken steps to make it easier to run many of our sample programs. You will see a TCPCONFIG macro. This macro tells Dynamic C to select your configuration from a list of default configurations. You will have three choices when you encounter a sample program with the TCPCONFIG macro. 1. You can replace the TCPCONFIG macro with individual MY_IP_ADDRESS, MY_NETMASK, MY_GATEWAY, and MY_NAMESERVER macros in each program. 2. You can leave TCPCONFIG at the usual default of 1, which will set the IP configurations to 10.10.6.100, the netmask to 255.255.255.0, and the nameserver and gateway to 10.10.6.1. If you would like to change the default values, for example, to use an IP address of 10.1.1.2 for the CPU Card, and 10.1.1.1 for your PC, you can edit the values in the section that directly follows the "General Configuration" comment in the TCP_CONFIG.LIB library. You will find this library in the LIB\TCPIP directory. 3. You can create a CUSTOM_CONFIG.LIB library and use a TCPCONFIG value greater than 100. Instructions for doing this are at the beginning of the TCP_CONFIG.LIB library in the LIB\TCPIP directory. There are some other "standard" configurations for TCPCONFIG that let you select different features such as DHCP. Their values are documented at the top of the TCP_CONFIG.LIB library in the LIB\TCPIP directory. More information is available in the Dynamic C TCP/IP User's Manual. IP Addresses Before Dynamic C 7.30 Most of the sample programs use macros to define the IP address assigned to the CPU Card and the IP address of the gateway, if there is a gateway. Instead of the TCPCONFIG macro, you will see a MY_IP_ADDRESS macro and other macros. #define #define #define #define MY_IP_ADDRESS "10.10.6.170" MY_NETMASK "255.255.255.0" MY_GATEWAY "10.10.6.1" MY_NAMESERVER "10.10.6.1" In order to do a direct connection, the following IP addresses can be used for the CPU Card: #define MY_IP_ADDRESS "10.1.1.2" #define MY_NETMASK "255.255.255.0" // #define MY_GATEWAY "10.10.6.1" // #define MY_NAMESERVER "10.10.6.1" In this case, the gateway and nameserver are not used, and are commented out. The IP address of the CPU Card is defined to be 10.1.1.2. The IP address of you PC can be defined as 10.1.1.1. User's Manual 53 CPU/BACKPLANE CPU/BACKPLANE 5.2.2 How to Set Up Your Computer for Direct Connect Follow these instructions to set up your PC or notebook. Check with your administrator if you are unable to change the settings as described here since you may need administrator privileges. The instructions are specifically for Windows 2000, but the interface is similar for other versions of Windows. TIP: If you are using a PC that is already on a network, you will disconnect the PC from that network to run these sample programs. Write down the existing settings before changing them to facilitate restoring them when you are finished with the sample programs and reconnect your PC to the network. 1. Go to the control panel (Start > Settings > Control Panel), and then double-click the Network icon. 2. Select the network interface card used for the Ethernet interface you intend to use (e.g., TCP/IP Xircom Credit Card Network Adapter) and click on the "Properties" button. Depending on which version of Windows your PC is running, you may have to select the "Local Area Connection" first, and then click on the "Properties" button to bring up the Ethernet interface dialog. Then "Configure" your interface card for a "10Base-T Half-Duplex" or an "Auto-Negotiation" connection on the "Advanced" tab. NOTE: Your network interface card will likely have a different name. 3. Now select the IP Address tab, and check Specify an IP Address, or select TCP/IP and click on "Properties" to assign an IP address to your computer (this will disable "obtain an IP address automatically"): IP Address : 10.10.6.101 Netmask : 255.255.255.0 Default gateway : 10.10.6.1 4. Click IP 10.10.6.101 Netmask 255.255.255.0 User's PC Ethernet crossover cable Direct Connection PC to Smart Star CPU Card 54 Smart Star (SR9000) 5.2.3 Run the PINGME.C Demo Connect the crossover cable from your computer's Ethernet port to the CPU Card's RJ-45 Ethernet connector. Open this sample program from the SAMPLES\TCPIP\ICMP folder, compile the program, and start it running under Dynamic C. When the program starts running, the green LNK light on the CPU Card should be on to indicate that an Ethernet connection is made. (Note: If the LNK light does not light, you may not have a crossover cable, or if you are using a hub perhaps the power is off on the hub.) The next step is to ping the board from your PC. This can be done by bringing up the MSDOS window and running the ping program: ping 10.10.6.100 or by Start > Run and typing the command ping 10.10.6.100 Notice that the orange ACT light flashes on the CPU Card while the ping is taking place, and indicates the transfer of data. The ping routine will ping the board four times and write a summary message on the screen describing the operation. 5.2.4 Additional Demo Programs The program SMTP.C (SAMPLES\SMRTSTAR\TCPIP\) demonstrates a basic Smart Star system using the SMTP library to send an e-mail when a keypress is detected on an LCD/keypad module. In order to run this sample program, edit the IP address as for the pingme program, edit the "mail to" e-mail address, compile the program, and start it executing. An e-mail corresponding to the keypad button that was pressed is sent. The program SSI.C (SAMPLES\SMRTSTAR\TCPIP\) demonstrates how to make the Smart Star CPU Card a Web server. This program allows you to turn the LEDs on an attached LCD/keypad module on and off from a remote Web browser. In order to run these sample programs, edit the IP address as for the pingme program, compile the program, and start it executing. Then bring up your Web browser and enter the following server address: http://10.1.1.2. This should bring up the Web page served by the sample program. The program SSI2.C (SAMPLES\SMRTSTAR\TCPIP\) demonstrates the use of I/O cards via instructions sent from a Web browser. You will need an A/D Converter Card, a D/A Converter Card, or a relay card installed on the backplane in order for the Web browser to be able to initiate changes on one or more of these I/O cards. Before you run this sample program, edit the IP address as for the pingme program, compile the program, and start it executing. The analog outputs will change or the relays will open and close in response to instructions sent from the Web browser. User's Manual 55 CPU/BACKPLANE CPU/BACKPLANE 5.2.5 LCD/Keypad Sample Programs Showing TCP/IP Features The following sample programs, found in the TCPIP subdirectory in SAMPLES/LCD_Keypad/122x32_1x7, are demonstrate the features of the LCD/keypad module connected to the backplane. Remember to configure the IP address, netmask, and gateway as indicated in the sample programs. * MBOXDEMO.C--This program implements a web server that allows Web e-mail messages to be entered that are then shown on the LCD display. The keypad allows you to scroll within messages, flip to other e-mails, mark messages as read, and delete e-mails. When a new e-mail arrives, an LED turns on, and turns off once the message has been marked as read. A log of all e-mail actions is kept, and can be displayed in the Web browser. All current e-mails can also be read with the Web browser. When using MBOXDEMO.C, connect the Smart Star CPU Card and a PC (or other device with a Web Browser) to an Ethernet. If you connect the PC and the CPU Card directly, be sure to use a crossover Ethernet cable; straight-through Ethernet cables and a hub may be used instead. * TCP_RESPOND.C--This program and TCP_SEND.C are executed on two separate single-board computers to demonstrate how the two boards communicate with each other. Use PCSEND.EXE on the PC console side at the command prompt if you do not have a second board. PCSEND.EXE is located with source code in the SAMPLES/LCD_Keypad/Windows directory. TCP_RESPOND.C waits for a message from another single-board computer. The message received is displayed on the LCD, and you may respond by pressing a key on the keypad. The response is then sent to the remote single-board computer. * TCPSEND.C--This program and TCP_RESPOND.C are executed on two separate single-board computers to demonstrate how the two boards communicate with each other. Use PCRESPOND.EXE on the PC console side at the command prompt if you do not have a second board. PCRESPOND.EXE is located with source code in the SAMPLES/LCD_Keypad/Windows directory. When a key on the keypad is pressed, a message associated with that key is sent to a specified destination address and port. The destination then responds to that message. The response is displayed on the LCD. Note that only the LEFT and UP scroll keys are set up to cause a message to be sent. When using TCPSEND.C and TCP_RESPOND.C, connect the CPU Card and the other single-board computer to an Ethernet. If you connect the them directly, be sure to use a crossover Ethernet cable; straight-through Ethernet cables and a hub may be used instead. 56 Smart Star (SR9000) 5.3 Where Do I Go From Here?

D/A CONVERTER CARDS User's Manual 99 D/A CONVERTER D/A CONVERTER Smart Star D/A Converter Cards (SR9400) 9. D/A CONVERTER CARDS Chapter 9 describes the features of the D/A Converter Card, one of the I/O cards designed for the Smart Star embedded control system. The Smart Star is a modular and expandable embedded control system whose configuration of I/O, A/D Converter, D/A Converter, and Relay Cards can be tailored to a large variety of demanding real-time control and data acquisition applications. The typical Smart Star system consists of a rugged backplane with a power supply, a CPU card, and one or more I/O cards. The CPU card plugs into a designated slot on the backplane chassis, which has seven additional slots available for I/O cards to be used in any combination. A high-performance Rabbit 2000 microprocessor on the CPU card provides fast data processing. 9.1 D/A Converter Card Features Three models of D/A Converter Cards are available, as shown in Table 17. Table 17. Smart Star D/A Converter Cards I/O Card Model SR9400 D/A Converter SR9410 SR9420 Features 12-bit D/A converter, 8 channels, 0 V - 10 V 12-bit D/A converter, 8 channels, -10 V - +10 V 12-bit D/A converter, 8 channels, 4 mA - 20 mA User's Manual 101 D/A CONVERTER 9.2 User Interface Figure 38 shows the D/A converter circuit. A buffer, U6, buffers the data signals D0-D7 from the Smart Star backplane, and sends them to the D/A converter, U2-U5. Signals D2- D5 are used to switch the chip select line to identify which D/A converter will perform the conversion. The model of D/A Converter Card determines the analog output ranges (0 V to 10 V, -10 V to +10 V, or 4-20 mA). The different voltage or current ranges are handled with different feedback resistors, as shown in Figure 38. A switching regulator provides a regulated power supply for the op-amps. 33 pF SR9400/SR9410 +5 V 825 kW D/A _SEN[07] U2U5 DA_DATA DA_CLK DIN SCLK /CS DAC 165 kW OUT + U10 100 W 0W D/A _OUT[07] D/A CONVERTER 33 pF SR9420 DA_DATA DA_CLK +5 V 8.25 kW U2U5 DIN SCLK /CS DAC OUT 165 kW 165 kW + U10 0W 10 W 8.25 kW D/A _OUT[07] Figure 38.

D/A Converter Card User Interface Pinout Let's look at Figure 40 to see how this happens. Assume the load is 500 . If the impedance of the wire used to connect the load to the output terminal on the D/A Converter Card is 5 , there will be a voltage drop of about 5 /500 = 1% across the wire. The voltage across the load will then be 1% less, which is about 40 counts for the SR9400. By connecting D/A_SEN as shown in Figure 40, the output driver will be able to sense the voltage drop across the wire and provide a more accurate voltage output across the load. If the load impedance is much greater than the impedance of the wire leads, simply leave the D/A_SEN sensing inputs open. 33 pF 825 kW D/A _SEN[07] + U10 100 W 0W 5W 5W D/A _OUT[07] 500 W Figure 40. D/A Converter Output for Low-Impedance Loads User's Manual 103 D/A CONVERTER The D/A Converter Card has eight analog output channels, D/A_OUT[0-7], and is also equipped with a remote sensing capability through sensing inputs D/A_SEN[0-7] for the voltage-amplifier versions of the D/A Converter Card (models SR9400 and SR9410). These sensing inputs compensate for the voltage drop across the wire leads of low-impedance loads to provide a more precise output across the load. 9.3 User FWT Connections Connections to the D/A Converter Cards are made via a ribbon cable connector or optional field wiring terminals that are either pluggable or have screw terminals.

Op-Amp Power Supplies There is provision in software using the anaOutDisable or the anaOutEnable function calls to turn the regulated 12 V power supply off or on since pin 5 on U1 is connected to PE7 on the Rabbit 2000 microprocessor on the backplane. This type of disabling/enabling allows the analog output channels to float in a high-impedance state. The voltage regulator on/off is disabled by default when there is a reset or when the D/A Converter Card is first used. All output channels must be configured to the required voltage or current outputs before calling the anaOutEnable function since unconfigured channels are automatically set to the maximum output. The -12 V supply is provided only for the SR9410, which provides analog outputs up to 10 V.

Relay Card Power Distribution The relay coil actuation voltage is 12 V, and so +V_USER should be 12 V to 30 V DC. The +V_USER supply passes through a linear regulator and comparator, which are in parallel. The comparator is set for approximately +13.9 V, and as long as +V_USER is more than +13.9 V, the +12 V from the linear regulator will provide the coil actuation voltage. Should +V_USER be less than +13.9 V, the comparator will supply +V_USER directly to provide the coil actuation voltage.

This allows the CPU Card to continue to keep track of time and preserves the SRAM memory contents while the power is off. The drain on the battery is typically less than 20 A when there is no external power applied. The battery can last 265 mA*h ----------------------- = 3.0 years. 10 A The drain on the battery is typically less than 4 A when external power is applied. The battery can last for 265 mA*h ----------------------- = 7.5 years. 4 A Since the shelf life of the battery is 10 years, the battery can last for most of its shelf life when external power is applied most of the time. APPENDICES 166 Smart Star (SR9000) C.2.1 Replacing the Backup Battery The battery is user-replaceable, and is fitted in a battery holder. To replace the battery, lift up on the spring clip and slide out the old battery. Use only a Panasonic CR2330 or equivalent replacement battery, and insert it into the battery holder with the + side facing up. NOTE: The SRAM contents and the real-time clock settings will be lost if the battery is replaced with no power applied to the Smart Star. There is a provision for an external battery if you need to save the SRAM contents and the real-time clock settings since the CPU Card needs to be removed from the backplane in order to change the onboard battery. CAUTION: There is an explosion danger if the battery is short-circuited, recharged, or replaced incorrectly. Replace the battery only with the same type or an equivalent type recommended by the battery manufacturer. Dispose of used batteries according to the battery manufacturer's instructions.

Smart Star CPU Card Backup Battery Circuit The battery-backup circuit serves three purposes: * It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting the current consumed by the real-time clock and lengthening the battery life. * It ensures that current can flow only out of the battery to prevent charging the battery. * A voltage, VOSC, is supplied to U14, which keeps the 32.768 kHz oscillator working when the voltage begins to drop. VRAM and Vcc are nearly equal (<100 mV, typically 10 mV) when power is supplied to the CPU Card. User's Manual 167 APPENDICES C.2.3 Power to VRAM Switch The VRAM switch, shown in Figure C-2, allows the battery backup to provide power when the external power goes off. The switch provides an isolation between +5 V and the battery when +5 V goes low. This prevents the +5 V line from draining the battery. +5 V R38 0W VRAM (not installed) Q6 FDV302P R37 10 kW /RES R36 22 kW Q7 MMBT3904 Figure C-2. VRAM Switch Transistor Q6 is needed to provide a very small voltage drop between +5 V and VRAM (<100 mV, typically 10 mV) so that the processor lines powered by +5 V will not have a significantly different voltage than VRAM. When the CPU Card is not resetting (pin 2 on U4 is high), the /RES line will be high. This turns on Q6, causing its collector to go low. This turns on Q7, allowing VRAM to nearly equal +5 V. When the CPU Card is resetting, the /RES line will go low. This turns off Q6 and Q7, providing an isolation between +5 V and VRAM. The battery-backup circuit keeps VRAM from dropping below 2 V. APPENDICES 168 Smart Star (SR9000) C.2.4 Reset Generator The CPU Card uses a reset generator, U4, to reset the Rabbit 2000 microprocessor when the voltage drops below the voltage necessary for reliable operation. The reset occurs between 4.50 V and 4.75 V, typically 4.63 V. The reset can be initiated either externally or by a watchdog timeout (WDTOUT) on the Rabbit 2000 microprocessor. +5 V U4 C9 10 nF RESET WDTOUT R10 100 kW RESET GENERATOR R16 10 kW U2:B EXT RESET Figure C-3. Reset Generator NOTE: The Dynamic C function chkWDTO is not able to detect whether a watchdog timeout has occurred on the SR9100 series of CPU cards. The GCSR status bits are read and stored by the BIOS, and the reset status bit would normally change once a reset has occurred. However, since WDTOUT is tied to the reset generator, a watchdog timeout forces a hardware reset, followed by the BIOS reading and storing the status bits corresponding to power-up or reset.

External Backup Battery Connection The external battery connection is useful if the SRAM and real-time clock data need to be preserved while the backup battery is being changed. This way power can continue to be applied to the CPU Card from the backplane (if the external backup battery is being replaced) or from the external battery (if the onboard backup battery needs to be changed since this requires removing the CPU Card from the backplane in order to access the onboard backup battery).

VRAM R31 /CSRAM /CS1 Q5 Q4 VRAM R37 10 kW /RES Figure C-5. Chip Select Circuit The current drain on the battery in a battery-backed circuit must be kept to a minimum. When the CPU Card is not powered, the battery keeps the SRAM memory contents and the real-time clock (RTC) going. The SRAM has a powerdown mode that greatly reduces power consumption. This powerdown mode is activated by raising the chip select (CS) signal line. Normally the SRAM requires +5 V to operate. However, only 2 V is required for data retention in powerdown mode. Thus, when power is removed from the circuit, the battery voltage needs to be provided to both the SRAM power pin and to the CS signal line. The CS control circuit accomplishes this task for the CS signal line. In a powered-up condition, the CS control circuit must allow the processor's chip select signal /CS1 to control the SRAM's CS signal /CSRAM. So, with power applied, /CSRAM must be the same signal as /CS1, and with power removed, /CSRAM must be held high (but only needs to be battery voltage high). Q4 and Q5 are MOSFET transistors with opposing polarity. They are both turned on when power is applied to the circuit. They allow the CS signal to pass from the processor to the SRAM so that the processor can periodically access the SRAM. When power is removed from the circuit, the transistors will turn off and isolate /CSRAM from the processor. The isolated /CSRAM line has a 100 k pullup resistor to VRAM (R31). This pullup resistor keeps /CSRAM at the VRAM voltage level (which under no power condition is the backup battery's regulated voltage at a little more than 2 V). Transistors Q4 and Q5 are of opposite polarity so that a rail-to-rail voltage can be passed. When the /CS1 voltage is low, Q5 will conduct. When the /CS1 voltage is high, Q4 will conduct. It takes time for the transistors to turn on, creating a propagation delay. This delay is typically very small, about 10 ns to 15 ns. APPENDICES The signal that turns the transistors on is a high on the processor's reset line, /RES. When the CPU Card is not in reset, the reset line will be high, turning on n-channel Q5. When a reset occurs, the /RES line will go low. User's Manual 171 APPENDICES 172 Smart Star (SR9000) APPENDIX D. SMART STAR SLOT ADDRESS LAYOUT Appendix D provides information about the register addresses for the various I/O card slots on the backplane. The information in this appendix will be of interest to more advanced users. User's Manual 173 APPENDICES The slots on the Smart Star backplane are accessed as external registers via the Rabbit 2000's assembly IOE prefix or via standard Rabbit BIOS functions. More convenient functions specific to the Smart Star control system have been written to provide more flexibility; for example, there is now a provision for the automatic update of shadow registers for each slot and for each register. The Smart Star design routes four address bits to each slot, providing 16 register addresses for each slot. These bits are passed through as bits 0-3 of the register address. The slot number itself is assigned to bits 6-8 of the address. In addition, the backplane design requires that bits 13 and 14 be high and that bit 9 be low. The simplest way to enforce this is to use a base address of 0x6000. Table D-1 provides the address layout for accessing the Smart Star slots, where Sn is the binary representation of the slot number (0-6), Rn is the binary representation of the register numbers (0-15), and X means the value does not matter. Table D-1. Smart Star External Register Address Bitmap A15 A14 A13 A12 A11 A10 0 1 1 0 X X A9 0 A8 S2 A7 S1 A6 S0 A5 X A4 X A3 R3 A2 R2 A1 R1 A0 R0 This bit mapping of the external register address provides the register addresses for each slot as listed in Table D-2. Table D-2. Slot External Register Addresses Slot Number 0 1 2 3 4 5 6 Address Range 0x6000-0x600F 0x6040-0x604F 0x6080-0x608F 0x60C0-0x60CF 0x6100-0x610F 0x6140-0x614F 0x6180-0x618F APPENDICES 174 Smart Star (SR9000) D.1 Digital I/O Card Channel Layout The Digital I/O Card layout is complicated by the standard Rabbit method of minimizing chip layout while adding channel arrangement flexibility. In particular, the nibble-wise layout of digital input channels requires fewer chips if fewer channels are desired. This is a common feature on Rabbit products and should not surprise most users. The digital output channel layout is straightforward. It is also possible to access the digital I/O channels in banks of eight channels. This method is significantly faster than reading eight channels one at a time, and so was included in the function call. Table D-3. Digital I/O Card Bank/Channel Mapping Local Board Address 0x00 0x01 0x02 0x03 Input Bank 0 2 1 2 Output Bank Input Channels 0-3/8-11 4-7/12-15 0-7 8-15 Output Channels User's Manual 175 APPENDICES D.2 A/D Converter Card Channel Layout The A/D Converter Card contains a single 11-input 12-bit A/D converter, TLC2543. The method of interfacing to this chip is a combination of single-bit writes via board registers and synchronous clocked serial access via the CPU Card's Serial Port B, which is extended across all eight slots. In addition, a serial EEPROM is installed on the A/D Converter Card to store the calibration constants. Table D-4.

Each channel is accessed by the slot, channel and device addressing scheme. The D/A Converter Card also has an EEPROM to store calibration constants. Table D-5.

User's Manual 177 APPENDICES D.4 Relay Card Channel Layout The Relay Card layout is complemented by the standard Rabbit method of minimizing chip layout while adding channel arrangement flexibility. In particular, the nibble-wise layout of the relay channels requires fewer chips if fewer channels are desired. This is a common feature on Rabbit products and should not surprise most users. The relay channel layout is straightforward. Table D-6.
