Rosslare MD-08 Installation And User Manual

MD-08
Wiegand to RS-232 Output Converter
Installation and User Manual
1. Introduction
The MD-08 is an easy-to-use Wiegand to RS-232 converter. It allows
you to connect a Wiegand reader directly to one of your PC's COM
ports. The MD-08 allows you to set employee and system codes
without having to use a reader attached to a controller in the network.

The communication settings are 9600 baud, 8 bits, 1 stop bit and no
parity.
The message is in the following format:
SS 02 FF 02 FF
Where:
 SS is the start frame: FF, FF, FF, 55
 YY is the number of Wiegand reception bits (in hexadecimal base)
 XX is the message check sum (without the start frame)
 DD is the incoming Wiegand bits data up to 96.
For less than 96 bits (for example 26-Bit only), the data contain
leading zeroes (70 leading zeroes for Wiegand 26-Bit).
Either 2 terminal blocks or a DC jack. A
reader can use a sink up to 100 mA
