GE MDS Master Station Setup Manual

INTRODUCTION

The MDS Master Station serves as a central station in a multiple ad-

dress system (MAS) wireless network. It provides long range, duplex

(or simplex) communication between a control point and associated re-

motes. It is fully redundant for mission-critical applications, and is a

compatible replacement for older MDS x790 Master Stations when or-

dered with the appropriate network interface modules.

The MDS Master Station works with a wide array of wireless equip-

ment, including MDS SD Transceivers, legacy MDS x710 radios, MDS

LN radios, and additional wireless options, depending on the modules

installed in the chassis.

All modules are installed on slide-in assemblies, accessible from the

front of the unit. A protective cover on the unit's face slides off, allowing

access to the modules and all interface connectors. In addition to com-

munication modules, up to two power supply units may be installed

and are available to suit a wide range of AC and DC power require-

ments.

Each module is secured to the chassis with knurled fasteners for easy

changes, when required. Figure 2 shows a common configuration of in-

stalled modules.

IMPORTANT: To ensure proper heat-sink engagement, the knurled

fasteners must be tightened with a screw driver to at least 10 inch-

pounds (approximately ¼ turn past hand tight).

Master Station modules are factory installed and cabled. Table 1 de-

scribes each module installed in a redundant configuration, from 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-redun-

dant version of the Alarm/Relay module is installed.

The MDS Master Station supports Ethernet or serial polling depending

on order options. A host computer may be connected to the appropri-

ate port on the chassis (LAN for Ethernet; COM1/2 for serial signaling).

Configuration of the unit is performed through a web interface. This re-

quires a LAN connection to one of the Ethernet ports on the Platform

Manager module. In addition, a command line interface (CLI) is availa-

ble through the mini USB port using the proper USB drivers available

at www.gemds.com.

Typical Application

Figure 3

on the following page shows a common arrangement of the

MDS Master Station as used in a licensed narrowband network. The

system shows both MCR and ECR transceivers in use.

Depending on order options, the MDS Master Station can communi-

cate with remotes employing Ethernet signaling, serial signaling, or a

mix of both.
