584 TMAA04-06 Linking and Interface Cable TM8100/TM8200 Service Manual
© Tait Electronics Limited November 2007
31.2 Connecting to a GPS Device
The cable provides an RJ-45 socket, which is used to connect a TM8260
dual radio system to a GPS device such as a Garmin-16HVS
antenna/receiver (product code TMAA05-01). GPS data is sent from the
antenna to both radios.
31.2.1 Installation
Plug the GPS receiver/antenna directly into the RJ-45 socket. The socket
is the correct type for the antenna, therefore the adaptor that is supplied with
the GPS antenna is not required.
For information on antenna mounting, refer to the instructions provided
with your GPS device.
31.2.2 Radio Programming
Program one or both radios with GPS settings as required. For detailed
configuration and programming information contact your local Tait dealer.
31.3 Connecting to the Ignition Signal
The cable’s external interface connector can be used to connect a TM8260
dual radio system to the vehicle’s ignition signal. This will turn the radio
system off when the ignition key is off to avoid draining the battery, and will
turn the radio system on when the ignition key is on.
Note A TMAA04-05 ignition sense kit is available. The kit comprises a
mating plug for the radio’s auxiliary connector and a 13 foot (four
metre) length of cable to connect to the vehicle’s ignition signal.
31.3.1 Installation
Connect pin 4 of the external interface connector (AUX-GPI3) to the
13.8V signal controlled by the vehicle’s ignition key.
Note Make sure the ignition switch and the radio link LK2 are properly
configured to reduce the radio's power consumption. Refer to
“TMAA04-05 Ignition Sense Kit” on page 581 for more infor-
mation.
31.3.2 Radio Programming
Program both radios as shown in Table 31.5.
