MA1505

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. www.DataSheet4U.com 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 © 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.
