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.
