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.
