I feel so stupid. I bought this Integra Receiver that I use in my garage used.

I figured out why the IR emitters did not work. Its because the original owner put a pieces of electrical tape over the whole IR area and it looked like part of the receiver. The blaster and the OEM remote could penetrate it, but not the emitters.

So I peeled it off and the emitters work. However I still can not get int IR input into the receiver to work.

It strange that the emitter, blaster work, but not a direct connection.

Its an MRF-250 as I have stated and I have to use an adapter from 2.5 mm to 3.5 so I can use a 3.5 mm cable to the IR input. Maybe all those adapters makes it so it doesnt work.
