RS-232 Interface When part No. is ISO 4011-P-B(or AB)user can choose RS-485 output or RS-232 output by internal keyswithch.Open product's coping,may see two button switching in the board,all aren't pressed is RS-485 output,two pressed is RS-232 output.When choose RS-232 output,please refer to Figure 2,9,10,12 separately connects to RS-232 interface RXD,TXD,GND. Alarm Signaling ISO 4011-P-A(or AB) analog input modules include High and Low alarm functions. High and Low alarm limits may be downloaded into the module's EEPROM by the host computer. The alarm functions can be enabled or disabled remotely. When the alarm function is enabled, both Digital Output channels are used to indicate the High and Low alarm state. Digital Output channel 1 (DO1) equals to High alarm state, and Digital Output channel 0 (DO0) equals to Low alarm state. The High and Low alarm states can be read at any time by the host computer. Every A/D conversion will be followed by a comparison with the High and Low limit.
Page 5 of 22
Shenzhen Sunyuan Technology Co.,Ltd. When the input value exceeds one of these limits, the High or Low alarm state is set to ON. There are two alarm mode options, Momentary and Latching. If the alarm is in Latching mode, the alarm will stay on even if the input value returns within the limits. An alarm in Latching mode can be turned OFF by giving a Clear Alarm command from the host computer. A Latching alarm is cleared by the module when the opposite alarm is set. When the module receives a value that is lower than the Low alarm limit, it will clear the High alarm and turn the Low alarm ON. When the alarm is in Momentary mode, the alarm will be turned OFF as soon as the input value returns within the limits. Initializtion ISO 40xx Module All ISO 40xx modules use RS-485 network,must distribute a only one address,between 00 and FF(hexadecimal),but,all new ISO 40xx modules use a factory initializtion set.As follows: Address: 00 (hexadecimal) Baud rate:9600 bps Checksum: disabled Because address codes of new module are the samee,their address will conflict to other modules,you must reconfigured every analog input address when you configure system.You can amend ISO40xx address by set command,after connecting ISO40xx power line and RS485. Baud ratechecksum state also need been adjusted according to users'need.You must install leap line before you amend baud rate,checksum state.All ISO40xx modules have a Pin mark with CONFIG.connect CONFIG Pin to ground (G2 pin),then connect power supply,this time they are in listening mode.Its set is as follows: Address :00 Baud rate 9600 bps Checksum: disabled Command Every command is used of a series characters,such as leading code,address ID,command,checksum, carriage return cr.Host computer is with "**" synchronous command,only command a ISO40xx module once. Command format:(delimiter character)(Addr)(Command)[data][checksum](cr) (delimiter character) is the first letter of command.All commands need a leading code.such as:%,$,#,@,... 1-Character (Addr) is module address code,if the following does not appoint,value range is 00FF (hexadecimal) 2-Character (Command)represents command code or variable value Variable Length [data] some output command need data Variable Length [checksum] represents optional parameters,only need it when checksum is enabled. 2- Character (cr) a control code as identify,is a terminating character, value is 0x0D 1- character When checksum is enabled,need [Checksum]The delimiter character is followed by a two-character address (hexadecimal) that specifies the target module..Command and response must append checksum characteristic.Checksum is used to check all input

Module Calibration In order to improve calibration precision,suggest to do as the following meters: 1Stable output,low noise DC voltage/current signal source 2High precision meter
Calibration Process:
1. Choose right input range,different input ranges need different calibration voltage 2. Connect right offset voltage to analoge input,thermocouple signal calibration voltage value,refer to Table 5-1 3. Send out offset calibration $AA1 command to analog input module,after signal stable 4. Connect right gain voltage to analoge input module,thermocouple signal calibration voltage value,refer to Table 5-1 5. Send out offset calibration $AA0 commandto analog input module,after signal stable 6. Finished Thermocouple signal calibration voltage Code 0E 0F 10 11 12 13 14 Thermocouple Input Range J(0760) K(01000) T(-100400) E(01000) R(5001750) S(5001750) B(5001800) Table 5-1 Offset Calibration Voltage 0mV 0mV 0mV 0mV 0mV 0mV 0mV Gain Calibration Voltage +50mV +45mV +25mV +78mV +22mV +20mV +15mV
