Relay board via Mastercard P2 Connector

[fsaviator]

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.
