    Relay board via Mastercard P2 Connector [SOLVED]

    Can someone let me know the process for connecting an OC Relay Card V.1 to a Mastercard via the P2 (DB9) connectors?
    The relay card works fine under USB.


    I hate to run another USB cable, and my relay card is mounted right next to my Mastercard. I have conencted them with a F-F serial cable but can't get it to appear in SIOC.


    When I use USB, it is fine, shows up in SIOC Manager, no issues.


    Is there code I need to add to my ini?


    Thanks,

    SOLVED!!!


    In order to use the P2 connector on the mastercard, you need a 1 to 1 F-F DB9 cable. DO NOT USE A SERIAL CABLE.


    Treat the lines in your script as outputs (49-55) as per the Mastercard manual.


    It will draw power from the Mastercard so configure jumper J2 appropriately.
