Locating the IR Sensor in your Device

IR Sensors are sometimes difficult to locate. It is important that when using an emitter cable that the emitter head on that cable be directly over the IR sensor of the device you want to control. Here are some tips to help find those sensors.

  1. Flashlight: You can use a flashlight to try to find the sensor behind the front panel of your device. Just place your flashlight directly on the front panel of your device and slowly move it across the panel while looking carefully behind the transparent panel. You will see what looks like a small round sensor at some point. If there is more than one part that looks like a sensor use the trial and error method to determine which one is the IR sensor.
  2. Trial and Error: If you can see the sensor or have some idea where the sensor is located, connect the IR Emitter cable to your Wireless or Wired IR Repeater and point your remote at the IR receiver that you have mounted on your TV. Move the Emitter bud, with the adhesive side against the panel, slowly over the surface of the front panel of the device you want to control while pressing a button up and down on your remote. When the device responds to the button presses then you have located the IR sensor. Continue this process until you have the best location with the strongest responses when pressing the button on the remote. Mount the emitter permanently with the adhesive back of the emitter.
  3. Camera Trick: There is a camera trick to check if the signal is going through the system correctly, but you will need a digital camera. The camera on your cell phone will work (Note: on smartphones,  you need to use the front facing camera for this trick to work).You to set up your units so that you can operate the remote by the receiver and see the transmitters on the other end at the same time, or just get someone to help you. If you operate the remote while pointing at the receiver and look at the end of the transmitter through the camera, you should see a blinking pale light coming from the transmitter eye. If you want to see what it looks like before you run the test, take a look at the eye on your remote through your camera and hit a remote button.If you can’t see the pale light coming from the transmitter, but the LED light comes on when you use the remote, there may be a defect somewhere in the system. You probably have a broken emitter. You can check this by swapping out the emitters and trying the camera test again.

    Note: The pale light from the IR emitter should be blinking. If you see a solid, continuous light shown through the camera from the emitter there is something defective.

    If it is correctly passing the signal, you probably have an incompatibility problem with the device you’re trying to control. You can double check this by setting up the units to control a different source, or installing it backwards and trying to control your TV. Incompatibility usually happens if different IR frequencies are used by different devices. They can range from 20 to 65 kHz.
