Hi Gary,
Sorry, I have to eat Humble Pie and apologise profusely - Having spent a full day re-reading all of your many previous posts and threads, I now realise I got things completely confused re your Flarm Mouse and Funke Transponder connections, so have adjusted my posts above accordingly.
For the avoidance of doubt, the correct response to your photos should have been: -
Port 1 (Top Left) is your remote Pilotaware GPS Mouse (Settings should be - Auto and 4,800 Baud)
Port 2 (Bottom Left) is the FTDI USB to RS232 Serial Converter - which in your case is being used 'in reverse' to connect your FlarmMouse to your Rosetta to allow direct integration of directly received Flarm data from the FlarmMouse into Pilotaware. This port should therefore (of course) be set to 'Flarm-IN' and '19,200 Baud'
Port 3 (Top Right) is the 1090 Receive SDR (Settings again - Auto and 4,800 Baud)
Port 4 (Bottom Right) is your new iGRID WiFi Connectivity Module (Settings again - Auto and 4,800 Baud)
If you want to avoid removing all the screws (yet again) to get to the Rosetta, you could try resetting the USB ports to the above settings, then 'SAVE' the settings, reboot the PilotAware and see whether the WiFi Connectivity Module comes on line. If not, then you need to try Lee's setup (i.e. unplug the FTDI connection and set all 4 ports (temporarily) to 'Auto' and 4,800 Baud).
Again, my apologies for any confusion caused.
Best Regards
Peter
