STATION SETUP
The MASTR III station comes pre-programmed and
ready to install, the only adjustments needed are the
required Line Output Level, the Line Input Level
necessary to produce Standard Deviation, and the Line
Cancellation for 2-wire Tone Remote Orientation. These
adjustments can be made using the PC Programming
option TQ-3353, or Utility PC software TQ-0619 with the
Utility Handset SPK9024.
SETUP PROCEDURE
Use the following procedures when setting up the
station using a Personal Computer (PC). If the Utility
Handset is plugged into the MIC connector, it must be
removed prior to resetting the system and using the PC
Programming software. Levels may be adjusted using the
MASTRUTL program supplied with the PC
Programming package. A RESET (on the Power Module)
should be initiated before programming starts.
1. Ensure proper connections are made to receive
and transmit antenna(s). See interconnect
diagram.
2. Plug the power cord from the base station into a
120 Vac, 60 Hz power source.
NOTE
If a 230 volt, 50 Hz source is used, connect the
locally required plug.
3. Connect the PC computer’s serial COM port and
the DATA PORT on the front of the T/R Shelf
using the TQ-3356 Interconnect cable
(19B801348P2).
If the computer has a 25-pin connector instead of
a 9-pin connector, an adapter must be installed.
The adapter may be either purchased or locally
manufactured. Making your own requires only
three wire connections (Figure 13).

4. If the system requires control by a remote unit,
the following interconnection must be made.
Connect the wires from the remote unit to the
six-pin terminal block (TB101). Use the
following information when making
connections:
TB101, Pins 3,4 - Line Input/Output for 2-wire
DC and Tone control.
or
Line Output for 4-wire DC and Tone control.
TB101, Pins 2,5 - Line Input for 4-wire DC and
Tone control.
TB101, Pins 1,6 - Line Inputs for E & M
signaling, DC Remote Control.

NOTE
P104, Pin 1 and P105, Pin 1 are on the far side
of the connector if you are facing the front of the
base station. Refer to Figures 16 thru 18.
5. The SQUELCH and VOLUME adjustments
should be made for proper operation. Unsquelch
the receiver by turning the SQUELCH
adjustment counter-clockwise. (If your base
station has Channel Guard, also activate the CG
switch.) Verify that unsquelched noise is going
to the speaker by increasing the VOLUME
(clockwise). Adjust the SQUELCH pot for
critical squelch (squelch just closes).
6. Following the initial setup, the MIC port may be
used for one of the following purposes:
a. Connecting the local microphone
equipped with a modular connector.
b. Connecting the multi-purpose Utility
Handset.
