42 Description
The auxiliary connector is the standard interface for external devices that are
typically connected to a radio. The auxiliary connector is a 15-way
standard-density D-range socket. The auxiliary connector provides a serial
port, three programmable input lines, four programmable digital I/O lines
and audio I/O.
The I/O lines can be programmed for a variety of functions, logic levels,
and in some cases, direction. Audio lines can also be programmed to tap
into, or out of, different points in the audio processing chain. For more
information refer to the online help of the programming application.
