Ever run into a problem with an IR repeating system where you just can’t get it to work with your remote?
Well, the IR repeating system may be functioning properly, but it could be that the IR carrier frequency of the remote that your are using may be beyond the specifications of the IR system. The IR carrier frequency is the frequency used by the remote to transmit the control signals such as ON/OFF, volume and channel and source selection, to the audio/video device.
Typical IR carrier frequencies from a few manufacturers are listed below:
- SpeakerCraft IR Receivers, 28 KHz to 90 KHz,
- Buffalo Electronics IR repeater/Receiver, 25 KHz to 100 KHz,
- Channel Vision CVIR5000, 30 KHz to 60 KHZ,
- MicroSmith HotLink, 18 KHz to 120 KHz.
If you have a remote that doesn’t seem to work, grab another remote and see if it works with the IR repeating. In addition, consult with the remote’s instructions manual to see if the carrier frequency falls in the specified range. Unfortunately, if your remote does operate beyond the specified range, well, there’s no solution for you at this time. But at least now you know why the system isn’t working.
