Optimising IR performance

The IR Eye and Blaster

The IR Eye and blaster enable the HD streamer to capture and transmit  IR commands from common remote control handsets, thereby relaying IR commands from the remote control handset to the source device. This page gives recommendations on how to set up the IR Eye and Blaster to enable optimal performance.

Positioning of the IR eye

The IR eye is connected to the receiver unit of the HD streamer.  Its function is to capture the IR commands from the remote control handset. The receiver unit then sends these commands to the transmitter. 

The IR eye should be positioned such that:

  1. There is a direct line of sight path (i.e. there is nothing to obstruct the IR signal) between it and the remote control handset.
  2. It is not in direct sunlight
  3. It is not in the direct path of other strong light sources (for example fluorescent lights).
  4. It is within 2 -3 meters of the remote control handset

 

Positioning of the IR blaster

The IR blaster is connected to the transmitter unit of the HD streamer. The transmitter unit receives the IR commands from the receiver unit and uses the IR blaster to send out the commands to the device which is being controlled.

The IR blaster should be positioned such that

  1. It is directly in front of and within in 2 - 3 cm of the IR receiver in the source device. Please see the locating the position of the source device IR receiver.
  2. It is not in direct sunlight
  3. It is not in the direct path of other strong light sources (for example fluorescent lights).

Locating the source device IR receiver

The IR receiver in the source device is different in every in every model. Here are some suggestions on how to locate the IR receiver in your source device.

  1. Look in the instruction manual for your source device. Quite often there is a block diagram showing device along with the position of the IR receiver and other buttons / features.
  2. Search on the internet. There are many enthusiasts who like to dissect electronic equipment including HDMI source devices, in such cases they will typically show where the IR receiver is located. An example of this for common models of Sky Boxes can be found here
  3. Using the source device remote control place it so that it is touching the front panel of the source device. Slowly move the remote control along the front panel of the device while pressing buttons on the remote control. Find the position where the remote control works most reliably. Put the IR blaster in this position.

The IR only works intermittently

  • Make sure the IR eye is plugged into the receiver and the blaster is plugged into the transmitter.
  • Make sure that your remote control is still working correctly by using it to control the source device directly
  • Check to see that when using the remote control through the HD sender does the Power LED (usually green) flash orange on both the Receiver and Transmitter unit
  • Check that the IR blaster is placed in close proximity to the IR receiver of your HDMI source

The IR Eye detects spurious IR activity (indicated by a the power LED randomly flashing orange)

  • Cover the IR eye with your hand. Check that the power LED stops randomly flashing orange. This will confirm if its detecting unwanted IR signals. If it does
  • Make sure the IR eye is not in direct sunlight
  • Make sure it is not in the direct path of other strong light sources (for example fluorescent lights)
  • Some LCD screens emit strong IR signals. Move the IR Eye around until a position is found where it does not detect the unwanted IR.
