1.1 Equipment Set-up
Introduction This subsection covers the setting up of the test equipment for servicing
the radios, as well as related aspects:
■ setting up of test equipment, including test unit
■ use of test unit
■ installing programming and calibration applications
■ basic programming and calibration tasks
■ invoking CCTM (computer-controlled test mode)
■ summary tables of CCTM commands and error codes
■ visual and aural indications provided by radio
The last-named aspect applies to control heads with UI, and concerns
the
STATUS LEDs and LCD screen, and the various alerts and confidence
tones emitted from the speaker.
Connect Equipment Connect the test equipment to the radio as shown in Figure 1.1. Use the
test unit, cables and adaptor of the service kit. The face of the test unit is
fitted with a speaker, five switches, and the following connectors:
■ “RADIO” connector (DB15 plug)
■ “COMPUTER” connector (RJ12 socket)
■ “TX AUDIO” connector (BNC socket)
■ “RX AUDIO/SINAD” connector (BNC socket)
These connectors are all required for connecting the test equipment and
radio. Figure 1.2 illustrates the face of the test unit.
Use of Test Unit The test unit facilitates the testing of the receive and transmit functions
of radios. When the switches are set for the required mode, the test unit
automatically routes all signals to the appropriate destinations. The unit
may be used with both mobile and portable radios. A full description is
given in the accessories manual. As shown in Figure 1.2, the switches
are:
■ SELECTOR switch
■ HOOK switch
■ MODE switch
■ AUDIO IN switch
■ AUDIO OUT switch
For servicing TM8200 radios set the
SELECTOR switch to “TM8200” . For
testing receive and transmit functions respectively, the remaining switches
must be set as described below. (When programming or calibrating
radios the switches have no effect, although it is good practice to set the
MODE switch to “RX” .)
