    Question ARINC 429 Cable pin 9 (Serial #1 GRD) - connects to ? (7.4 manual self contradiction)

    Talking 4500 boxes here.

    I have the ARINC 429 cables made up. In doing my final cross checking I discovered that I had configured the ARINC Serial #1 GRD wrongly.
    I had connected this to pin 2 of the EFIS Expansion DB9 connector but the 7.4 manual drawing on page 126 shows it connecting to pin 5 of the EFIS Expansion.

    I couldn't understand why I had made this mistake so went searching the manual again.

    I found that the EFIS Expansion Connector Table on page 101 shows the Serial #4 GRD as being pin 2. So that's where I got the specification from for my wiring
    That table simply labels EFIS Expansion pin 5 as "GROUND".

    Which EFIS Expansion Connector pin should be used for the ARINC Serial GRD? Pin 2 or pin 5? Or will either work?

    It would be good to remove the document contradiction at the next release of the manual.

    Thanks,

    Pin 2 and Pin 5 are both ground pins.

    I would power the EFIS and battery charge circuit from the same VPX Power pin. The TCW battery charge can take 3 1/2 Amps and the EFIS is 3 1/2 Amps so it will need to be on a 8 amp circuit.
