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.
