Thread: EFIS Serial Ground Connections

    EFIS Serial Ground Connections

    For the ARINC module, Drawing 53620WD (ARINC Adapter dwg) states 'Serial #1 GND Pin - NOT REQUIRED' (G430W connection). EFIS dwg 53600 shows this ground connected.....which is correct? How about for Serial 2 and Serial 3....are grounds required for those?

    And for the Magnetometer? Is a ground required for this?

    Thanks

    The 430w does not have a dedicated ground pin for each serial port, so you don't connect it. If the device your connecting needs a dedicated ground connection than you use it.

    Yes, the magnetometer shows a pin for it so connect it.

    Thanks. Are all of the serial grounds common in the AFS unit? In other words, can I use the serial ground 1 (not used due to G430 installation) for serial device 3 ground, and therby avoid two wires connecting to serial 2/3 ground?

    They are the same in the EFIS, this question does not make sense. We provide pre wired shielded three conductor cables for each of the serial ports, why would you run the three conductor cable to the device and then also run another ground wire from another serial port?
