An IR extender, like the BlastIR, allows you to extend the IR signal from your remote control so that you can keep your audio/visual equipment out of sight without losing the ability to control them remotely. But what do you do if it’s not working? Well there are a few simple things you can do to troubleshoot the problem. While the setup section applies specifically to the BlastIR, the troubleshooting techniques discussed here could apply to other IR Extender systems.

Need to troubleshoot the InjectIR?

Proper Setup

If your BlastIR system isn’t set up properly, it’s not going to work, so let’s take a look at what a proper setup should look like.

BlastIR Connection Diagram

BlastIR, What's in the Box

What’s in the box:

  • (1) Receiver
  • (1) Connecting Block
  • (1) Power Supply
  • (4) Dual-Head Emitters

Each head on the emitter cables transmits an identical signal; that means you can control up to 8 devices with the same IR extender kit. The connecting block can support up to 6 dual head cables, meaning you can control up to 12 devices.

BlastIR Setup
  1. Each emitter cable plugs into one of the numbered 3.5mm ports labeled “Emitters.” Plug however many emitter cables you will need to control your devices into these ports. Make sure to place the emitters so that they have a clear line of sight to the IR “eye” on your source. If you’re not sure where the eye is, place the transmitter far enough back to be able to “see” the whole front of your device.

  2. Plug the power cable into the port with the red LED labeled “Power 12V DC.”

  3. Plug the receiver into the 3.5mm port labeled “IR Reciever” on the same side of the connecting block as the power port. Make sure to place the eye of the receiver somewhere with a line of sight to your remote control.


Checking the Signal

Blue LED

Okay, so we’ve made sure your BlastIR is set up correctly but it’s still not working. If that’s the case, we need to see if your system is even repeating the signal from your remote. If the blue LED lights on the receiver and the connecting block light up when you are using your remote, the system is receiving an IR signal.

Camera Trick

Camera Trick

There is a cool trick to check if the signal is going through the system correctly, but you will need a digital camera. It doesn’t need to be fancy, even the camera on your cell phone will work (Note: on some of the newer smartphones, like the iPhone 5, you need to use the front facing camera for this trick to work).

You need to set up your BlastIR 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 button.

If you can’t see the pale light coming from the transmitter, but the blue 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 and you should contact us.

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 BlastIR to control a different source, or installing it backwards and trying to control your TV. Incompatibility usually comes because of the IR frequencies used by different devices.

Note: The BlastIR is NOT compatible with the following models of the AT&T U-verse cable box: IPN 4320 and the Motorola VIP series.
