Installation Precautions
This equipment contains devices that are susceptible to static charges. The procedures
outlined in this installation guide should therefore be carried out in a static-safe
environment. You can obtain information on antistatic precautions and the dangers of
electrostatic discharge (ESD) from standards such as ESD S4.1-1997 (revised) or BS EN
100015-4 1994. The Electrostatic Discharge Association website is http://www.esda.org/.
Installation
1
Program the radio. We recommend you do this prior to board installation to isolate any
hardware problems introduced during board fitting.
Ensure the TM8000/TM9000 radio is programmed with the following settings:
Programmable I/O form, Digital tab
If line interface enable/disable control is needed, set the following:
Programmable I/O form, Audio tab
PTT form, External PTT (1) tab
2
Configure the external D-range SK1 signals if required.
The available TA2922 variants have different signals available on the external D-range
connector SK1, determined by the factory fitting of the top-side zero ohm resistors to
a 26x9 matrix.
The external options connector SK1 pin out details for the available variants are:
