Wiegand to RS232 Converter (MA1405) April 2004 Copyright © 2003 MaCaPS International Limited http://www.macaps.com.hk Page 1 of 4 Wiegand-to-RS232 Converter (MA1405) MaCaPS MA1405 is a Wiegand-to-RS232 Bidirectional converte r. 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 Specification:
