I had perfectly working iTach WF2SL and WF2IR combo controlling my home theater (used with iRule). I decided to replace them with GC-100-12 because I needed another serial port. In the current setup, in addition to the serial port I have 3 IR cables going out - 1) a cable directly going into IR port on Oppo player, 2) an emitter controlling cable box 3) a blaster (a simple one; no additional hardware) controlling projector.
After replacing iTach devices with GC-100-12, cable box and projector are not working. I tried to change IR cable but the issue remains. I see that green light next to IR port used for cable box is not lighting up but the light next to projector port is lighting up; not sure why this is happening. But regardless none of these two devices receive any signal. I tried switching different ports for different devices; Oppo always worked but not the rest. Any help with resolving this issue will be greatly appreciated. Thanks in advance!
