FT-2900R Operators Manual, page 61 - 'Packet Operation' is provided below.

The FT-2900R may be used for 1200 bps Packet operation, using most all commonly available Terminal Node Controllers (TNCs). Connections between the transceiver and the TNC are accomplished via the front panel microphone connector and rear panel External speaker jack, per the diagram below.

The audio level from the receiver to the TNC may be adjusted by using the VOL knob, as with voice operation. The input level to the FT-2900R from the TNC may be adjusted via Set Mode Item "27 MCGAIN"", see page 64 for details.

Be sure to turn the transceiver and TNC OFF before connecting the cables, so as to prevent voltage spikes from possibly damaging your transceiver.

Remember to readjust the default microphone input level to "LVL 5" (Set Mode Item "27 MCGIN") when Packet operation is finished.
