28 Description of the Radio Interfaces TM8000 3DK Hardware Developer’s Kit Application ManualSeptember 2003 © Tait Electronics Ltd2.4 Internal Options ConnectorWhen installing an internal options board, the internal options connector isthe electrical interface to the main board of the radio body.The internal options connector provides similar I/O to the auxiliaryconnector. The digital signals and the serial port are independent of theauxiliary 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-MaTchconnector.Examples of internal options boards: TMAA30-02 3DK Application Board.Refer to the TM8000 3DK Application Board Service Manual. TMAA01-01 Line-Interface Board.Refer to the TM8100 Mobile Radio Accessories Manual.
