TMAA04-06 Cross-band Linking, GPS and
External Interface Cable
Installation Instructions
Notice
The TMAA04-06 cross-band linking, GPS, and external interface cable is
DMR only. It is
not
currently supported by P25 radios.
The TMAA04-06 cross-band linking, GPS, and
external interface cable is used to extend the
features available with TM9356 dual radio
systems. The cable connects to both radio’s
auxiliary ports so the radio system can be used as a
cross-band repeater, provides an RJ45 socket to
connect to a GPS antenna, and also provides an
external interface connector. The external interface
can be used to power a TM9356 dual radio system
on using ignition sense, and also connect to an
external alert device.
Notice
The radio does not meet the IP54 pro-
tection standard once the auxiliary connector
rubber bungs have been removed and this cable has been installed. Care must be taken
when the radio is being operated in an environment where there is water, dust or other
environmental hazards.
Analog Cross-band Repeater Operation
Cross-band repeater mode allows a TM9356 dual radio system be used as a temporary analog
repeater. Any activity received on one radio will be automatically transmitted on the other
radio, and vice versa.
Installation
1. Remove the rubber bung that cover the auxiliary connector on each radio body.
2. Plug an auxiliary connector into the auxiliary port of a radio body.
3. Plug the second auxiliary connector into the auxiliary port of the other radio body.
The cable can be plugged in either way—its orientation has no impact on radio perfor-
mance. However, to reduce the cabling required, orient the cable so the external interface
connector and GPS socket are closest to the device or devices to connect to.
4. Tightly fasten the jackscrew-type locks.
