MD-D04
4-Reader Expansion Board
Installation Manual

1.
Introduction
The MD-D04 is an optional expansion board for use with Rosslare
Security's family of state-of-the-art AC-425 networked access
controllers.
The expansion board adds an additional four reader or keypad inputs;
four relay outputs and four supervised inputs to the access control
panel.
As a result, an access control panel with an MD-D04 expansion can
support a total of eight readers and eight door panels. In addition, it is
possible to add any keypad or biometric reader that supports the
Wiegand or Clock & Data transmission formats.
The host access controller has complete control over the additional
readers, inputs and outputs of the MD-D04 expansion board. The
inputs and outputs can be configured using an access control software
system such as Rosslare Security's AxTraxNG™. The software system
also configures the MD-D04's reader card transmission format and
input connection topology.
This guide explains how to install and begin working with your new
MD-D04 access control panel expansion board.

Attaching the MD-D04
1.
Disconnect power to the access control panel before attaching the
MD-D04.
2.
Remove the MD-D04 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-D04 into the gap in
the panel cover labeled "IO EXPANSION SLOT" (Figure 2). The text
on the MD-D04 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-D04 circuit board.
6.
Replace the cover on the expansion board, using it as a guide to
ease the MD-D04 into the panel's 10-pin female connector.
