I agree with Don, why not do AFSK and eliminate all the extra hardware
and cables? No one except you will know the difference.

Peter,
You will have to gain access to the RS-232 DTR or RTS signals.
If you do not have the P3, you can insert the RJ45 to serial port
dongle and pick the signals from that connector. Although I have not
tried it, I believe it will work.
You will also need to use a "one transistor keying interface" (google
for it) to convert the signal level to TTL for driving the ACC
connector FSK pin.
If you do have the P3, you can add a "Y" cable to the P3 connector
labeled "PC" to gain access to the serial port signals.
Actually, you will likely find it easier to use AFSK A and drive the
audio from the internal soundcard in the K3S.
