So far I did connect the garage door opener (liftmaster 3280m) to 4-Relay Module on OPII.
when I connect the cables to relay module I cannot use my hard wire garage door ( Let me know if something is wrong with this setup )
Since garage door opener does not show the common wire I hotwired it and red pin is common and two white pins are NC and NO (that's what i think).
I set the output on PC Access to GENERAL PURPOSE
BSR Edit: Additional info from the OP via another thread on this topic:
I have OPII and got 4-Reolay Module to control the garge door to open and close from my phone and HAI 5.7e.
I have liftmaster 3280m and when i connect the NC, C and NO my hardwire garage door opener does not work.
i am not sure if photo link will work but here is the link so you can see how i have wired this thing.
I have program the Output in OPII to General Purpose .
any idea what i am doing wrong?
is the cabling? I am not what what is Common NC NO cables for liftmaster or i need to chagne the settings in PC Access?
Thank you for your help everyone
