MD-D04B
4-Reader Expansion Module for AC-425x-B Control Panels
Installation Manual
1
1. Introduction
The MD-D04B is an optional expansion board for use with Rosslare’s
AC-425x-B series of networked access control panels.
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-D04B 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-D04B 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-D04B's reader card transmission format and input
connection topology.
This guide explains how to install and begin working with your new
MD-D04B access control panel expansion board.

3. 2BInstallation
To install the MD-D04B expansion board:
1. Disconnect power to the access control panel before attaching the
MD-D04B.
2. Remove the MD-D04B 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.

4. Wiring Instructions
4.1 Input Wiring Options
There are six input wiring options:
Normally Open
Normally Closed
Normally Open Supervised with one or two resistors
Normally Closed Supervised with one or two resistors
Normally Open Switch
Normally Closed Switch
Figure 3 shows the normally open input connection.
Figure 2: Normally Open Input
Figure 4 shows the normally closed input connection.
Figure 3: Normally Closed Inputs
Figure 5 shows the normally open supervised input connection with
single resistor.
Figure 4: Normally Open Supervised Inputs with Single Resistor
Normally Open Supervised inputs with one resistor must be connected
with an 8.2K resistor in parallel to the input switch contacts.
Always wire resistors on the input switch and not on the
terminal block.
Figure 6 shows the normally open supervised input connection with
double resistor.
Figure 5: Normally Open Supervised Inputs with Double Resistor
Normally Open Supervised inputs with two resistors must be connected
with an 8.2K resistor in parallel and a 2.2K resistor in series to the
input switch contacts.
Figure 7 shows the normally closed supervised input connection with
single resistor.
Figure 6: Normally Closed Supervised Input with Single Resistor
Normally Closed Supervised inputs with a single resistor must be
connected with a 2.2K resistor in series to the input switch contacts.
Figure 8 shows the normally closed supervised input connection with
double resistor.
Figure 7: Normally Closed Supervised Input with Double Resistors
Normally Closed Supervised inputs with two resistors must be
connected with an 8.2 K resistor in parallel and a 2.2 K resistor in series
to the input switch contacts.
4.2 Outputs
Electrical devices can be switched using the voltage free relay contacts.
Rosslare recommends using suppression diodes for all outputs that are
connected to inductive loads and activated by DC current, such as
Magnetic Lock ("Maglock") or door strike devices.
Each suppression diode must be connected near its inductive load.
Always attach the diode's cathode to the +V terminal of the load.
Attach the diode's anode to the –V terminal.
For more information, refer to your access controller's Installation and
User Guide.
4.3 Readers
The reader terminal supports the reader's two data lines. For Wiegand
readers, these are data lines D0 and D1. For Clock & Data readers, D0
is the DATA line and D1 is the CLOCK line.
There is also support for a tamper signal input from the reader and for
one LED control output to the reader.
Proximity and keypad readers are supplied with a limited cable. The
color of the cable cover represents the cable’s function.
In general, the cable length should be no more than 150 m with an 18
AWG cable. Refer to each reader's installation guide for specific details.
Readers connected through an MD-D04B are recognized as "Reader
5",”Reader 6”,”Reader 7”, and "Reader 8" in the software system.
Figure 9 shows the wiring for Readers 3 and 4, respectively.

5. Using the MD-D04B
5.1 Operating the MD-D04B
The access control panel detects the MD-D04B expansion board when
it powers up. When defining the panel in the access control panel's PC
application (such as AxTraxNG™), select the option designating the
panel name with a designation of “MD-D04B”.
Readers, inputs, and outputs must be defined using the access system
software. Readers connected through an MD-D04B are recognized as
"Reader 5",”Reader 6”,”Reader 7”, and "Reader 8" in the software
system.
Define each input's type and make sure the connection is compatible
with the input wiring. When selecting inputs and outputs from the
software, note that input and output type and function in the access
control software normally reflect the host access control panel's
general purpose inputs and outputs.
When using AxTrax, define input types from the "Inputs" tree menu.
Input and output functions are defined using the "Links" element
within each "Panel" tree menu item.
For more information, refer to the
AxTraxNG Software Manual .
