28 Description of the Radio Interfaces
When installing an internal options board, the internal options connector is
the electrical interface to the main board of the radio body.
The internal options connector provides similar I/O to the auxiliary
connector. The digital signals and the serial port are independent of the
auxiliary connector signals, but the AUD_TAP_IN, AUD_TAP_OUT,
AUX_MIC_AUD, RSSI signals are shared with the auxiliary connector.
The internal options connector is an 18-pin 0.1in pitch Micro-MaTch
connector.
Examples of internal options boards:
TMAA30-02 3DK Application Board.

Refer to the TM8000 3DK Application Board Service Manual.
TMAA01-01 Line-Interface Board.
