7. IR Control System
At Matrix end: Insert the 3.5mm jacks of the IR TX Emitters included with the unit into the IR
TX Emitter ports at the rear of the matrix according to input. The IR signal is added to the HDMI of
the input device so, for example, if the user is watching Blue-ray on input 1, the IR signal will be
directed through the IR TX1 socket to control the device.
As each IR TX port is allocated to an individual HDMI input port, if the user is unable to
establish IR control of the device, care should be taken to check firstly, that the IR emitter and
HDMI input ports match (Input 1-TX1, Input2-TX2 etc.) with plugs secured in correct ports.
Secondly, that the IR TX emitter sensors are firmly attached directly to the front of inputs and
covering infrared sensor windows of the source devices.
Some later adjustment may be needed to the location of the sensor to achieve the best
performance results - sometimes moving the sensor to different areas on the source can improve IR
performance.
NOTE: Infrared receiving areas of devices can be located by shining a flashlight onto the front
of the device – the sensor should be able to be seen through the plastic as a small, round object
inside. Insert 3.5mm jacks of IR RX receivers into RX ports, making sure the receivers
themselves are placed in clear view to receive an infrared signal from the remote handset used
to control the display outputs.
