MDS SD Master Station
Setup Guide
The MDS SD Master Station serves as a central station in a mul-
tiple address system (MAS) wireless network. It provides long
range, duplex (or simplex) communication between a control point
and associated remotes. It is fully redundant for mission-critical
applications, and is a compatible replacement for older
MDS x790 Master Stations.
The master station works with a wide array of wireless equipment,
including MDS SD Transceivers, legacy MDS x710 radios, and
additional wireless options, depending on the modules installed in
the chassis.

left to right. For a non-redundant configuration, blank plates are
used in place of the redundant power supply and radio modules,
and a non-redundant version of the Alarm/Relay module is
installed.
The master station supports Ethernet or serial polling depending
on order options. A host computer may be connected to the appro-
priate port on the chassis (LAN for Ethernet; COM1/2 for serial sig-
naling).
Configuration of the unit is performed with a PC, using a web inter-
face. The PC connects to the front of the radio’s Platform Manager
module. Configuration options are similar to those of the SD Trans-
ceiver, and the radio supports full SD functionality in transparent
mode. In addition, a command line interface (CLI) is available
through the mini USB port using the proper USB drivers.

Figure 3. Application Example
2.0 INSTALLATION
Refer to the figures which follow for these steps, as required:
1. Mount the unit. The unit may be rack-mounted (2U high) in a
19-inch rack cabinet, or may be placed on any sturdy tabletop
or other flat surface. The installation site should be free of
excessive dust, and should have adequate ventilation. The
chassis should be positioned so that all interface cabling will
reach the required connectors.
When rack mounting, the rack ears can be installed in one of
three positions to allow flexibility in the mounted depth of the
chassis. The unit should be mounted so as to maximize air-
flow around the rear heat sink.
2. Connect Antenna Feedlines. All coaxial antenna connec-
tions are made to the Type-N connectors on the rear of the
unit. The number of connections depends on options ordered,
including duplexer options, as follows: Separate TX and RX;
Combined TX/RX; RX Out, RX In; and TX.

Figure 5. Internal Duplexer (or internal T/R switch),
Single N connectors
Figure 6. External duplexer or dual antennas
(TX and RX ports pass directly through)
3. Install the Data Interface Cabling. Interface connections are
made to the front of the Platform Manager module. Typical
connections for most sites include:
•Serial Data—Attach data equipment to the front panel
COM1 and/or COM2 ports. The unit is hardwired as a DCE
device, thus a straight-through Ethernet cable may be used
in most cases (DB9-F to RJ-45 connector, GE MDS part no.
73-2434A12).
•Ethernet LAN—Attach data equipment to the ETH1 and/or
ETH2 port. The auto-sensing MDIX feature allows either a
straight-through or crossover cable to be used.
Where applicable in the steps that follow, secure all cable connec-
tions with the locking screws provided.
4. Connect Primary Power—The Master Station is powered
using one or two power supply modules that work in tandem.
The modules may be AC, DC, or a combination of both. The
following tables list each type and key operating parameters.
Table 2: AC Power Supply Module
Module Input Power Current Rating
All DC power supply modules have chassis isolated inputs
and a diode bridge for floating ground, positive ground, or
negative ground installations. These modules include a keyed
power connector with screw-terminals. Strip the wire leads to
6mm (1/4 inch) and insert them into the wire ports provided.
Be sure to observe the polarity shown below. Tighten the bind-
ing screws securely and insert the connector into the module.

5. Connect a PC for Configuration (LAN or USB port). This
prepares the master station for programming of desired oper-
ating parameters. Configuration is further described in Section
3.0.
NOTE: If serial-based cabling is used for configuration, an
adapter may be required at the PC, as many PCs do not
offer a serial port. In such cases, a USB-to-Serial adapter
(with appropriate driver software) may be used. These
adapters are available from a number of manufacturers.
6. For redundant units, the Alarm/Relay module includes a man-
ual override toggle switch, which can be set into one of three
positions to associate it with a particular radio. The toggle
switch is locking, and must be pulled out to change positions.
Switch functions are as follows:
Up—Radio A; Down— Radio B; Center—Automatic.
When the switch is set to Automatic, the active radio is deter-
mined by radio module presence and alarm status. If only one
radio module is installed (A or B) it is recommended that the
switch be set to A or B, as appropriate.
7. Radio, Alarm/Relay, and Duplexer Connections—The
Alarm/Relay module provides two alarm outputs, one for
major and one for minor alarms. This module also provides
TX/RX audio, PTT (TX keying), and analog RSSI connections.
See Section 6.0 for pinout connections.
All other required connections on the front of the unit are
cabled at the factory per ordered options.
