Hey Everyone! Thanks for responding! First post and Its kinda like screaming across the desert to see if there is anything out there. It might just respond! What I'm doing is programming a Xantech kepad! I am controlling a Dvd, Vcr, Sat and routing the vid through a projector in a remote room, The rack room is about a hundred feet away. I have everything functioning fine in the rack room. By this I mean, I programmed the keypad in the rackroom with the Dragon 450 software and everything routes and ramps the volume. Life is good! Used a small Lcd tv with Av inputs to see what was routed through the receiver, Audio fine, video fine. Take the panel to the remote room and and only video routes not audio, ? is wire length a issue? Do I need seperate wires for power or IR? Tommorrow will drape a cable on the floor to see it something is squirreled with the wire. My last thought is power? Am I on borderline of just enough but not enough? I did put a 470ohm resistor across the IR and Status to build the current a little, but to no avail. Oh sorry! The cable I'm using to the remote room is 4 conducter 18g sheilded! Please respond!

Helloooo.

Are you using the same device to route the audio and video signals and its receiving and responding to some commands and not others? Or are you using two separate switching devices, and one works but the other doesn't? What are the devices, make and model? Do you have an ir emmitter with visible output, ie blink or test ir?

BTW, the most effective way to troubleshoot ir repeating sytems is to break the system down to its simplest form, one emiiter, one "sender", and one device, and add the additional elements (including long cable runs) one at a time until the system fails and identifies the proximate cause.

It is likely that the trouble is the long run of control cabling is picking up EMI/RFI along the way, increasing the signal to noise to the degree that some commands are undecipherable. Its the reason sheilded cabling is often used, and the path low voltage cabling is run is an important detail.

Xantech offers a detailed guide diagramming some common applications for ir repeating on their website if you would like to check your connections.

PS Complaining about the lack of FREE advice is IMO poor form. I certainly hope that you plan on contributing something worthwhile.

The reason you got the response you got before was because of the vague question you asked. Macros are a list of commands you design to accomplish a task for your specific equipment. Other peoples macros really won't help you since they most likely have a different setup than you. No one was rude, they just had a little fun with you. As for this current question I'm not exactly sure what you are asking. You say that the video is functioning, but not the audio, then mention what wire you are using for your IR/Keypad. If it is swithing your video, but not audio, then it is not an issue with your IR to the rack because it is switching the video. I would check your audio connections first.
