DESCRIPTION
The ORION Desk Top Station is an all solid state station
for local/remote control operation. The most advanced manu-
facturing techniques are used to provide the highest quality and
reliability.
The station is available in all frequency bands and up to
mid power levels available in the ORION Mobile radio family.
MECHANICAL PACKAGE
The station is housed in an attractively styled Desk Top
cabinet and operates over a wide range of AC power sources.
The basic station consists of a Control Panel, a 30-ampere
power supply, and an ORION mobile radio unit. The Desk Top
Station operates from 120 or 240 VAC sources at 50/60 Hz. In-
put power variations of ±20% are tolerated (see Figures 1 and
2). The basic Desk Top Station package combination is
equipped with:
•AC Power Supply (120/240 VAC, 50/60 Hz)
•Interconnect Board
•Speaker, 3.5 inches for improved radio audio quality
•Slow speed, low noise, 12 VDC fan
The transmitter power output of the Desk Top Station is the
same as the selected mobile radio. The station meets all appli-
cable radio EIA standards.
Interconnect Board
The Interconnect Board interconnects the radio in the Desk
Top Station with the controls and options. See LBI-39052 for
full details. When the radio and options are connected, the fol-
lowing functions are controllable:
•Receiver Muting (RX Mute)
•Audio Switching
•Local Keying
•Channel Guard Monitor
•Volume Adjustment
•Frequency Selection
•Voltage Regulator and Power Supply choice
The Interconnect Board is provided with jacks for connec-
tion to:
•Radio
•Control Panel
•Power Supply
•Station Speaker
•Station Fan
•Desk Top Microphone
•Clock/VU Module (Option)
A single transistor (Q201) is used to reduce the 13.8 VDC
power supply voltage to a suitable voltage to power the station
fan. Except for this transistor, the only other circuitry on the In-
terconnect Board consists of jack interconnections.
OPERATION
INTRODUCTION
The front panel of the Desk Top Station, as shown inFigure
1, includes the front of an ORION mobile radio, as well as a
Control Panel. The station is assembled as a standard station
with or without one of the combinations of options. The Con-
trol Panel is illustrated for each combination.
1. Standard Desk Top Station, without Options - The
standard station has only a single red LED to indicate
when the power supply is ON (see Figure 2).
The power supply ON/OFF switch is mounted on the
rear of the station housing.
OPERATION OF THE STANDARD
STATION WITHOUT OPTIONS
Operation of the standard station without any option begins
with turning ON the POWER switch. The POWER switch is
located on the rear of the power supply, accessible at therear of
the Desk Top Station housing. The POWER indicator lights,
showing that the power supply is ON. The radio is NOT on yet.
The Power Supply provides power to the station cooling fan.
The fan is thermally controlled and is on only when there is
sufficient heat inside the station cabinet. The radio has its own
ON/OFF POWER switch.
The radio uses the Station Speaker mounted behind the
front cap of the station. The radio has no internal speaker.
Further operation of the station is that of the ORION Mo-
bile radio. Refer to the applicable Operator’s Manual for more
detailed information.
CLOCK/VU Option
See LBI-39032 for full details.
