    EFIS expansion connector in Main vs ARINC drawings

    When I wired the ARINC, I obviously used the Ex. Conn. pinout shown on the ARINC drawing, with serial #4 GND to pin 5. As I prepared wiring for a spare GPS puck (needs power from the 5V terminal in the Expansion Connector), I noticed that on the EFIS Main drawing, the Ex. Conn. shows serial GND to pin 2.

    I realize that both pins are common to the chassis, and this is very 'late to the party', but if the drawings carry forward to current products, it might confuse someone doing a new install.

    FWIW,

    Charlie

    Thanks for the note, those drawings really need to be updated to remove the switch as well.

    Are you talking about the autopilot ARINC source select switch? If so, can you elaborate on why it's no longer needed? Is there another way to select the source? (This is for a 4500sEE.)

    Thanks,

    Charlie

    The switch is more prone to failure then the EFIS and most people have problems with either the switch failing or having the switch is the "override" or navigator direct mode.
