Thanks everyone, apologies if I messed anyone about by posting twice. I was getting really confused as I had followed the original advice and bought the cable with the D9 connector attached. I have however today managed to get to aircraft and followed all the advice given and it's still not working so now wondering if I have a 'fake' cable. Just ordered the version with bare ends from RS. When that arrives I will connect the Orange cable straight to the Yellow/Violet Dynon RX Serial Port 2, and the black onto a spare Dynon D37 Black. The USB end of the cable will go into the lower middle USB (port 2) on PAW.
Then configure as advised setting PAW Port 2 to 'Flarm Out' and set initially 115,200 Baud IIRC), dropping to 57600 if I can't see anything. I will configure Skydemon as SERIAL IN DEVICE to FLARM TRAFFIC, the INPUT FUNCTION to TRAFFIC and the SERIAL IN/OUT BAUD RATE to a minimum 0f 115,200 Baud ( and the SERIAL OUT DEVICE to NONE.
I think this is what you have all now advised,
Cheers
James
