I have had another session on my problems with the remote rig (RRC) boxes tonight and tried to get the CAT control of my FT-847 working. My cables worked back to back for Audio, PTT and CAT, but when the RRCs were in line, the CAT wouldn’t play for some reason even though the audio and PTT transferred perfectly! The owner of remote rig, Mike SM2O is very helpful and I have finally got everything going, but not exactly as he suggested.
On my remote rig V1 boxes I now use the *front* com port, the rear ones as suggested by Mike don't work for me (the FT847 requires a serial pass through so perhaps that is the issue?). I had tried lots of different things including permutations of software settings and hardware configs, but on a whim I swapped around serial port pins 2 and 3 at the RRC control end in case some pins on the serial port pass through were directional. Voila - everything was OK! I went and repeated my back to back CAT cable test (I.e. without the RRC in line) and nothing was working but it did before the pin swap. So, was my serial back to back adapter actually a null cable which had caused me all this pain? When I did a continuity test, it was straight through, so that wasn't the issue! I have to say that I don't really understand, and it isn't so easy to test continuity further as I am using a custom cable from a microham MKII. But it is finally working, so I am delighted.
Next job is to install the kit at the operating desk and make sure everything works over my LAN.
