Microphone
The TB7100 programming and calibration applications are connected to the
base station via the programming/microphone socket. This socket is an
8-way female RJ-45 connector. Use the T2000-A19 programming lead and
a TMAA20-04 adapter to connect your programming computer to the base
station. It is possible to plug the RJ11 directly into the RJ45 socket without
the use of the adapter, but this is not recommended. A microphone can also
be connected to the TB7100 base station via this socket. The pin allocations
for the programming/microphone socket are given in the following table.
