INSTALLATION – WIRING INSTRUCTIONS
For most installations, only the power cable connection and the antenna connection are required.
However an installation of two TDAM-1000 transceivers can take advantage of the ‘Cross Mute’
feature available on the 26 pin HD D connector. The Cross Mute function will mute the other
receiver whenever one of the radios is transmitting. A mating 26 pin HD D connector is supplied
in the installation kit.
2.5.1 J1 PINS 1 AND 2 – MAIN POWER INPUT
Use supplied power cable to connect to vehicle accessory power source.
2.5.2 J3 PINS 8 AND 9 – EXTERNAL SPEAKER AND –
10 watt speaker output at 8 ohm impedance. The speaker output includes receive audio only. The
Level is set by the volume control. The speaker output is also available on a 1/8” phone jack (J2)
on the back of the radio. The output amplifier is of a ‘bridged‘ type, so both + and – must not be
connected to ground.
2.5.3 J3 PIN 26 – MONITOR AUDIO
Line level audio output receive and sidetone (mic) audio combined. Not affected by the volume
control.
2.5.4 J3 PIN 25 – HEADSET AUDIO
0.5 watt 600 ohm audio output. Includes receive and sidetone (mic) audio. The level is set by
the volume control. Can be used when a remote user position is required, leave unconnected
otherwise.
2.5.5 J3 PIN 7 – CROSS MUTE INPUT
Receive audio will be muted on the speaker, headset and monitor outputs when this input is at 10
volts. Connect to the cross mute output on the second radio.
2.5.6 J3 PIN 16 – CROSS MUTE OUTPUT
10 volt output during transmit and 0 volts during receive. Connect to the cross mute input of the
second radio.
2.5.7 J3 PIN 6 – REMOTE MIC AUDIO
Microphone audio input. Mic DC bias voltage is supplied. Can be used when a remote user
position is required, leave unconnected otherwise.
2.5.8 J3 PIN 18 – REMOTE PTT INPUT
Push to talk input. Radio will transmit when this line is brought to ground. Can be used when a
remote user position is required, leave unconnected otherwise.
2.5.9 J3 PINS 11, 14 AND 17 – GROUND
Ground. Connected to signal and chassis ground.
2.5.10 J3 PIN 24 – SQUELCH OUTPUT
Squelch signal output. Open collector output which goes to ground when squelch is open.
2.5.11 J3 PINS 1 TO 5, 10, 12, 13, 15 AND 19 TO 23 – BASE STATION INTERFACE
For base station applications only. Do not connect.
