MDX/ORION Desk Top Station

INTRODUCTION
This manual contains instructions for the assembly of a
Desk Top Station. This is done by installing an MDX mobile or
ORION mobile radio into the Desk Top Station Assembly, us-
ing the hardware kit supplied.
Mobile radios which can be accommodated by the Desk
Top Station are all MDX radios and ORION up to the mid
transmitter power levels. Only the local control version station
is available for the ORION mobile.
Included are mounting instructions for the radio, as well as
instructions for making the few required cable connections.
Installation is made easy with the help of an Installation Dia-
gram and an Interconnection Diagram, included as part of this
manual.
UNPACKING AND CHECKING
EQUIPMENT
Hardware Kit 349A9561 was used to assemble your sta-
tion. The unused material was shipped with the station. Re-
move the kit and store for possible use.
Installation of the Desk Top Station includes three parts:
1. Installation of the Mobile Radio in the Desk Top Sta-
tion Assembly using Hardware Kit 349A9561 (sup-
plied).
2. Installation of Option Boards in the Desk Top Station
Assembly, in accordance with options selected. Re-
mote Interface Board Option, with one of the follow-
ing remote boards:
a. DC Remote Board
b. 4-Channel Tone Remote Board
c. 5-Channel EDACS Tone Remote Board
d. Standby Power Transfer Option
e. Clock/VU Meter Option
3. Installation of the Desk Top Station in theplace of op-
eration with the necessary power, antenna, micro-
phone, and line connections.
INSTALLATION
PREPARATION OF DESK TOP STATION
1. Loosen the two (2) captive screws which hold the
top cover on the Desk Top Assembly. Remove the
cover.
2. Disconnect cable W2 from J202 on the Intercon-
nect board and also from J215 (ORION Applica-
tion).
3. Loosen, Do Not Remove, the two (2) M3.5 screws
that hold the radio mounting bracket on the Desk
Top Station Assembly.
4. When external wires for options are to be con-
nected, remove and discard the round knockout but-
ton in the rear of the station housing. Insert the
rubber grommet 5490407P10 in the hole. Place the
cable clamp (344A3480P1) around the wires. Snap
the cable clamp retainer into the hole adjacent to
the grommet.
PREPARATION OF MOBILE RADIO
MDX Radio
1. Remove the bottom cover of the radio by removing
the four (4) retaining TORX®screws.
2. Unplug the radio internal speaker cable from J904
on the radio and let it hang.
3. Discard the rubber plug and in its place slip the rub-
ber sleeve on cable W2. P905 of W2 plugs into
J905.
4. Replace the bottom cover of the radio with the four
(4) retaining TORX®screws removed in Step 1.
5. Using a permanent marker, copy the FCC identifi-
cation number of the radio onto the Desk Top Sta-
tion FCC label.
6. Attach the side mounting brackets with four (4) hex
mounting screws and four (4) washers (2 per side)
in the sides of the radio.
ORION Radio
1) No special modifications required.
2) Attach the side mounting brackets with four (4) hex
mounting screws (2 per side) in the sides of the ra-
dio.
INSTALLING THE MOBILE RADIO
1. Connect P202 of cable W2 from the radio to J202
on the Interconnect Board. Also connect P215 to
J215 when ORION radio is used.
2. Connect P101 of the Desk Top Station antenna ca-
ble W1 into the RF TNC connector on the radio.
3. Power Cable Connections:
a. MDX - Connect P1 of the Desk Top Assembly
power cable W3 to J1 of the radio power cable
W901.
b. ORION USA Version - Connect P1 of Desk
Top Assembly power cable W3 to J1002 on the
rear of the radio unit.
c. ORION European Version - There is no cable
W3. The power connections are included in ca-
ble W2 which connects to the DB37 connector
on the radio unit.
4. Place the radio in the mounting bracket and posi-
tion it for the proper Desk Top Station front appear-
ance and tighten the two (2) M3.5 screws that hold
the radio mounting bracket in place.
5. Replace the Desk Top Assembly cover using the
two (2) screws loosened in Step 1 of "PREPARA-
TION OF DESK TOP STATION."
This completes the installation of the mobile radio in the
Desk Top Station Assembly.
INSTALLING THE DESK TOPSTATION
AC Power
The Desk Top Station power supply must be connected
to AC power with the fused and ON/OFF-switched AC
power cable found at the back of the Desk Top Assembly.
The transformer straps are shipped set for a 120 volt power
source:
120 volts ±10%, Single-Phase, 50/60 Hz, 4 amps,
500 watts
Refer to Power Supply Maintenance Manual LBI-38751
for procedures to change the transformer straps to accommo-
date a 240 volt power source:
240 volts ±10%, Single-Phase, 50/60 Hz, 2 amps,
500 watts
Different Desk Top Station power supplies may have dif-
ferent current capabilities. Refer to the applicable power su-
ply maintenance manual for current usage.

Speaker Level
1. After the Remote Board is set up so that the remote
consoles are transmitting and receiving properly with
the Desk Top Station radio, adjust the intercom levels
on the Remote Interface Board:
a. Adjust R325 for the proper station speaker level
from the remote console microphone.
2. Replace the Desk Top Assembly cover with the two

CLOCK SETTING INSTRUCTIONS
The following separate items may be set: 12/24 hr display
mode, hours, minutes, and display intensity. The time keeping
stops when in any of the set modes. The clock seconds (not
displayed) are set to zero any time a display is altered. Thus, if
setting to the nearest second is desired, the operator must set
the time one minute ahead of the presetn time then wait for the
reference clock to advance to the displayed time before exiting
the set mode. To set the clock:
•Press SW1 approximately 1 sec.
A "12__" or "24__" will display indicating the display
mode. Press SW2 to alternate between modes. When
the correct mode is displayed.
•Press SW1 approximately 1 sec.
The time will display (no flashing colon) with hours
intensified. Press SW2 to advance the hours. Holding
SW2 down will auto increment at about 3 counts per
second. Note the dot in the upper left indicates PM.
When the correct hour is displayed.
•Press SW1 approximately 1 sec.
The time will display with minutes intensified. Press
SW2 to advance the minutes. When the correct min-
utes are displayed.
•Press SW1 approximately 1 sec.
The time will display at the set intensity (no flashing
colon). SW2 changes the intensity. Four intensities are
available. When the correct intensity is displayed and
the reference clock advances to the next minute.
•Press SW1
The colon will now flash and the time keeping contin-
ues.
VU METER TEST/CALIBRATION
TEST
Apply a 1 kHz tone at OVRMS to J101-1 DESK MIC HI
and J101-2 DESK MIC LO. Ground J101-3 DESK MIC
PTT. No LEDs should be lit. Increase 1 kHz tone level. The
LEDs should turn on one at a time. All green/yellow LEDs
should be lit at a level of 100 mV. All red LEDs should be lit
at a level of 175 Mv.
CALIBRATION
The VU meter should have been calibrated at the factory. If
the dot at the lower right hand corner of the display is lit,
then calibration must be performed.
If the calibration must be changed, a calibration mode is en-
tered by removing power from the unit, then while holding
down SW1, powering the unit. The unit will display a 3 digit
number. Supply a 107 mV 1 kHz signwave to the Desk Mic
Hi input (J101-1 & 2) and ground the Desk Mic PTT input
(J101-3). The bar graph will operate. SW1 will increase the
gain (decrease the displayed number) while SW2 will de-
crease the gain. These switches must be tapped, not held to
set the gain. The range of the displayed number is 80 to 205
with 128 being the default (typical calibration value). In-
crease the gain until one red bar lights, then decrease the
gain until this red light goes out. This is the ideal calibration
point. To exit the calibrate mode and store this calibration
constant and the key, press and hold down SW1 for about 5
seconds. The module will resume normal operation.
The VU meter bar graphic display is inactive during the
time setting mode.
NOTE PROGRAMMING NOTES
MDX
PC Programming is accomplished through jack J101 on the desktop station. The MDX mobile can
only be flashed programmed via the microphone connector on the radio unit.
1. The volume control must be set to level seven (7) and the enable activated.
2. When the remote interface board is installed, the volume control must be set for fixed volume.
3. When the station is local control only, the volume control mustnot be set for fixed volume.
ORION
PC Programming is accomplished through jack J101 on the desktop station.
1. Auxiliary input #2 must be set to PTT.
2. The volume control is not fixed for the local control station.
