Introduction
The MD-IO84B is an optional I/O expansion board for use with Rosslare’s
AC-225x-B and AC425x-B series of networked access control panels.
This expansion board adds an additional four relay outputs and eight
supervised inputs to the access control panel.
The host access controller has complete control over the additional inputs
and outputs of the MD-IO84B expansion board. The inputs and outputs
can be configured using an access control software system such as
Rosslare AxTraxNG™. The software system also configures the MD-IO84B's
input connection topology.
Once connected to the system, these IO devices can allow you to scale and
expand your system and by using AxTraxNG™ management you can
program extended access control features, adding more automation
capability to the your system.
This guide explains how to install and begin working with your new MD-
IO84B access controller expansion board.

Attaching the MD-IO84B
To attach the MD-IO84B:
1.
Disconnect power to the access control panel before attaching the
MD-IO84B.
2.
Remove the MD-IO84B cover by lightly pulling one of the cover knobs
away from the circuit board. The entire cover comes away from the
board.
3.
Peel off the label on the cover of the panel marked "Remove to install
I/O board".
The label is located on the same side of the panel as the DIP switch.
4.
Insert the 10-pin male connector of the MD-D02B into the gap in the
panel cover labeled "IO EXPANSION SLOT".
The text on the MD-D02B must face the same way as the text on the
panel cover.
5.
Tighten the screws securing the cover to the access control panel, and
the four Philips screws on the MD-D04B circuit board.
6.
Replace the cover on the expansion board, using it as a guide to ease
the MD-D04B into the panel's 10-pin female connector.
