TA2922 TM8000/TM9000 Universal Line
Interface Board Installation Instructions
TAIT: THE RIGHT FIT
Introduction
The TA2922 universal line interface board is fitted into the TM8000 and TM9000 radios
and is functionally equivalent to the AM8000-UIS manufactured by Tait Australia. It features
hardware and software-configurable options for features such as phantom DC keying
options, tail and anti-kerchunker timers and a flexible supply voltage monitoring alarm.
Available variants are:
■ 8-wire isolated line interface (TA2922-01)
■ 2-wire line interface (TA2922-02)
■ 6-wire line interface (TA2922-03)
■ 6-wire balanced line interface with unbalanced speaker output (TA2922-04)
■ 6-wire marine line interface (TA2922-05)
■ 6-wire -10dBm line interface (TA2922-06)
The TA2922 kits provide the following items:
■ TA2922-xx PCB assembly
■ 18-way micromatch loom
■ D-range foam seal
■ D-range hood parts
■ D-range screw locks (x2)
■ M3x8 taptite screws (x6)
The interface board fits inside the radio in the
options cavity and is connected to the main PCB
by the internal options loom. The 9-way D-range
connector mounted on the interface board fits
through the external options connector hole
provided in the radio chassis.
A configurable matrix allows the integrator to
allocate any of 26 different I/O signals to any of
the nine pins on the external 9-way D-range
socket.
Important: The radio does not meet the IP54
protection standard once a TA2922 board has
been installed.
