Hi Kurt,
I actually wrote the paper on the PilotAware site about integrating FLARMMouse into PilotAware. I have done this with FLARMMouse, FLARM Red Box and PowerFLARM Core. The principle in each case is exactly the same, though the detail varies slightly depending on the device. The only real difference between the 6 pin RJ12 and 8 pin RJ45 connectors is that with the 8-pin type, either Pin 1 or Pin 2 of can be used for ‘Power +’ and either Pin 7 or Pin 8 for ‘Power -‘. With the 6-pin RJ12, only a single pin at each end is used for ‘Power +’ and ‘Power -‘ connection.
As you will have seen from the PowerMouse Manual, one of the RJ45 sockets is normally used for Power Supply (using Pins 1 and 8 or 2 and 7). The other socket is normally used to feed data to a dedicated FLARM display. If you want to retain a FLARM display and connect to PilotAware, you can either use a splitter to feed the Display and the PilotAware from the second socket, or make up your own lead to supply power to the PowerMouse (via pins 1 and 8,) and feed data to your PilotAware via pins 4 and 5 from the same socket, leaving the other socket free for your display. In either case, you need to connect Pin 5 of the socket to the Yellow wire in the FTDI USB cable and Pin 4 of the socket to the Black wire. Either of the above will work fine.
Any problems or further questions, please come back to me.
In any case, please let us know how you get on.
Best Regards
Peter
