Appendix B. Using the MD-08
The MD-08 is a 26-bit wiegand to RS232 converter. It allows you
to connect a 26-bit wiegand Reader directly to one of your
PC’s COM ports. This permits you to program Employee and
System Codes without being in Online Mode. This provides the
convenience of not being required to use a reader attached
to a controller in the network when setting Employee and
System Codes.
Instead, you may program Employee and System Codes using
a Reader attached to the MD-08. You could even pre-
program all the Employee and System Codes for a network in
your office prior to departing to the site of the AC-115 network
you are installing or maintaining.
There are three ways to attach 26-bit wiegand readers to the
MD-08:
• Wiring a reader directly to the MD-08’s terminal block
• Attaching a Rosslare reader directly to the MD-08’s
connector input
• Installing Rosslare’s MD-12W Prox Reader Module directly
into the MD-08
