The XCVario can be connected to the on-board network with this cable and to a FLARM with RJ45 standard IGC assignment e.g. Classic FLARM, Power FLARM, has a temperature sensor and an input for the speed-to-fly switch. The FLARM can be read out with this cable Both RX and TX are wired, therefore the second serial interface is provided bi-directionally for further devices such as OpenVario.
All versions variometers are completely compatible with the FLARM cable. The cable is also compatible with all versions, but it isn’t possible to connect a second device. Downloading the flight data over this cable is possible with all the variometers.
