Test radiator coverage
Best practices for good infrared signal reception
- There should be no objects between the receiver and the transmitter.
- Do not attach any kind of object, such as the headphone cord or a sticker, on the top of the receiver where the infrared sensitive diode is located.
Test the coverage area
After installation you need to test the coverage of the transmitter in the room itself.
- Configure the channels as described here .
- Activate the test tone on the transmitter using the web server ( see ).
- Plug in headphones to activate the receiver.
- Test the reception quality in all positions and directions. Go around the room and test all positions that should receive the infrared signal using the test tone.
Causes for bad infrared reception
One option for the lack of reception is that you are testing an area that is not covered by the footprint of the radiator. Another reason is the presence of objects between the radiator and the receiver that block the infrared radiation. This could be structural elements such as balcony, poles or beams.
When the infrared system has multiple radiators which use different cable lengths, the signal will reach the radiators at different times. As a consequence the radiation from the different radiators can cancel each other out. Solve this by using the automatic delay line compensation (). It is possible that you may need to tune these settings a little inside the room.
Typically you can identify a black spot as an area of bad reception that only occurs along a specific line and/or rotating the receiver into another direction will restore the reception. Confirm this type of interference by turning of one of the radiators. Typically higher bands are more sensitive to black spots.
Other systems using infrared at certain frequencies can disturb the reception of the receivers. Disable the bands that can experience interference using the web server. See for more information.
