| RS232-to-Wiegand Bidirectional Dual Wiegand Port Converter (MA1505) January 2006 RS232-to-Wiegand Bidirectional Dual Wiegand Port Converter (MA1505) MaCaPS MA1505 is a RS232-to-Wiegand Bidirectional Dual Wiegand Port converter. The converter can automatically convert Wiegand input from 3-bit up to 42-bit to a formatted ASCII string. When the formatted ASCII string is used as input to the RS232 port of another MA1405 unit, the formatted ASCII string is reconverted to Wiegand format output. 1 1.1 Specification: Communications: 9600 BPS ASYNC, 8 bits, 1 Stop, No Parity. 1.2 Wiegand Input/Output Format The format of the Wiegand bit stream is shown as follows: Copyright (c) 2006 MaCaPS, Inc. http://www.macapsinc.com Page 1 of 4 RS232-to-Wiegand Bidirectional Dual Wiegand Port Converter (MA1505) January 2006 1.3 RS232 Input/Output Format The format of the RS232 is in the form of 16-byte ASCII string (In Hex format) as follow: The Parity Character P is decoded as follows: RS232 Side P 0 1 2 3 PS 0 0 1 1 Wiegand Side PE 0 1 0 1 2 Pin Connectors: The schematic of the MA1405 is shown in the following figure.
