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 Blu-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 con-
trol 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, and 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 de-
vice – 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.
At display end: Insert the IR RX Receiver jack into the IR RX port of the display receiver balun, with the re-
ceivers themselves placed in clear view on or near the displays to receive an infrared signal from the
remote handset used to control inputs. Insert the IR TX Emitter jack into the IR TX port of the display re-
ceiver balun, ensuring that the emitter sensor is securely attached to infrared sensor window of the dis-
play. Follow the same connection and positioning for all baluns/displays connected to the matrix. If all IR
TX Emitters and IR RX Receivers are positioned and connected correctly with sources, displays and dis-
play receivers fully powered and the matrix set to IR call-back enabled and IR TX Switch mode activated,
two-way IR will now be possible.
Note: Misplaced or poorly secured IR Emitters and Receivers may result in intermittent IR control signals
passed to and from the matrix. Check your placement and adjust if necessary.
