Can't see much of a PilotAware element to this.
Looks like you'll need to buy or make up a cable connecting port 3 (basic) or port 2 (clever) on your TRX 1500 to your Aircrew via the correct pins (5, 6, 7) on your RJ45 on your Aircrew. That's DB15 to RJ45, will need soldering and a crimp tool.
Then configure the baud rate in the Aircrew device.
You've already got ADS-B direct and FLARM via ground stations in the PilotAware AFAICT, just connect USB from Aircrew to PAW and configure.
Or am I missing something?
