2.4.2.2. Pinout of the RJ-45 connectors
Remember, that the TX/RX lines of port 2 and port 3 (CDTI interfaces) are reversed to the IGC
standard. Pin 3 provides a 3.3V DC power supply for powering external FLARM displays. This makes
the interface compatible to existing external FLARM compatible displays.
Power can be supplied via each port. Be sure to power only FLARM and TRX-2000 via these lines to
prevent exceeding the maximum current.

To prevent injury on the TRX-2000 and/or connected devices, always
check the pinout of the used connection cable.
Damages caused by reverse polarity or wrong connection are not covered
by the manufacturer's warranty.
The pinout complies with the standards of the International Gliding
Commission (IGC) for flight recoders. The pin numbering is reversed to the
industrial standard.
