Overview

This section introduces you to the CDM Control Station; out-

lines major components; physical appearance; accessories;

general information about cables, and basic assembly of the

Control Station.

CDM Control Station

The Control Station provides a low cost integrated base sta-

tion package with enhanced control and audio accessory fea-

tures. The station is unique because it is designed to use off-

the-shelf mobile radios for the transceiver. This design pro-

vides the additional benefits of quick repair and minimizing

inventory. The unit is completely self-contained, with radio,

power supply and necessary electronics mounted in an

attractive desktop cabinet.

A few features that distinguish the Control Station:

• Portability

The Control Station is a self-contained, portable,

desktop unit.

• Local Desktop Control

The Control Station provides enhanced control func-

tions through conveniently located front panel but-

tons. These functions include: Intercom, Supervisor,

Monitor, and Transmit. The front panel also houses

an internal microphone to allow communication

without the aid of an external audio accessory.

• Audio Accessory Connections

The Control Station provides easily accessible audio

ports from the front panel that allow direct connec-

tion of a headset or desk microphone.

• External Accessories

The Control Station provides a 16-pin accessory con-

nector for additional peripheral components

• Fan

The Control Station has a single speed , thermal switch

controlled fan.

• Power Supply

The Control Station has a 15 Ampere, continuous

duty switch mode power supply.

Mobile Radio Compatibility

The CDM Control Station was designed to incorporate the

CDM750, CDM1250, or CDM1550 mobile radios.

CDM Control Station

Physical Description

The following paragraphs describe the physical characteris-

tics of the Control Station.

• CDM Control Station Housing

• CDM Control Station Fan Assembly

• CDM Control Station Power Supply

• CDM Control Station Interface Circuit Boards

CDM Control Station Housing

The Control Station housing provides the necessary mobile

mounting that will make up the customer's free-standing

Control Station. The Control Station is shipped from the fac-

tory with the fan assembly, control interface, and power sup-

ply already installed in the housing. Before you can assemble

the Control Station, the housing must be partially disassem-

bled as described in Section 3, CDM Control Station Instal-

lation of, this manual.

CDM Control Station Fan Assembly

The fixed-speed 12 VDC fan assembly is mounted onto the

rear wall of the Control Station cabinet. A thermal switch

from the power supply is connected to the heatsink on the

underside of the transmit radio and monitors the temperature

of the radio. The fan turns on when necessary.

CDM Control Station Power Supply

The Control Station operates using voltages generated by the

HPN9033 power supply. The power supply operates from a

115 / 230 VAC (switch selectable) power source. The power

supply provides power for the fan assembly and radio. The

power to the interface electronics is obtained from the radio's

accessory connector. The power supply has three connectors:

• One pigtail with a 2-prong "Ford" connector to mate

with the radio power connector.

• One pigtail with a 6-position connector to power the

fan.

• One IEC ac receptacle for various line cords (U.S.

Standard, 3-prong, 115 VAC cord provided).

A slide switch on the power supply allows thermal control or

continuous ON fan operation.
