Strange Problem With IR

I have zones that can be controlled via a touch panel or via an RTI remote via an the AMX IR receiver port plugged into a local ni700.

The problem is that the touch panel can control all the tv's power on / off, etc with no errors or problems, but the same commands are being sent via a function with the RTI remotes and I having intermittent issues with the tv's power on / off. I am logging all the info and the log is being updated with the correct zones and functions when the RTI's are being used. I have tried the following commands to get the power on / off for the displays:

Send_Command dvDisplay,"'CP',28";
Send_Command dvDisplay,"'SP',28";
Pulse[dvDisplay,28]

The only difference is the IR Receiver plugged into the amx port of the master.

Any suggestions?

    Perhaps the RTI's IR is interfering with the TV's IR port...the TV is seeing 2 IR signals, one from the RTI and one from the AMX.

    You could try masking the TV's receiver with those fancy IR covers, or black electrical tape always does the trick, though not as professional.

    That is a good thought I will let the guys know and try that

    I had an issue with the NI-700s IR send/receive a while back that just had me cussing.

    After working with tech support we found that there are certain times that receiving and sending IR on the unit simultaneously could cause a problem; particulary if the the IR fiels were entered in by HEX. Trigger the IR file manually worked fine. Also delaying the execution of the IR send solved the problem. This was a big problem for things where the user might hold donw the button like volume/ch up and whatnot.

    Eric,

    Thanks for the info. In the current setup the only ir files that are on the ni 700 are the ones for the local tv's ( there is a ni 700 where ever there is a tv ) the audio / video is distributed through a switcher so the only ir commands that are sent are the on / off to the tv's.
