IR receiver cable extender jacks.
When the display device is not near to the matrix, the IR cable will be too short. There is a pair
of jacks supplied for extending the IR (RX) cable. Please use an appropriate (min. 3 conductor
shielded audio cable) or an additional CAT5e/CAT6 cable to form the IR cable extender.
Additional wires unused should be grounded at the connector on the Matrix end of the line only.
Use the male jack and female jack to extend the IR_RX cable like the

CONNECT AND OPERATION
1) Connect the HDMI input sources into 4x4 HDMI Matrix and note the input chosen.
2) Connect the HDMI outputs of the Matrix to the 4 HDMI Display inputs.
3) Connect the IR RX receiving cables into Matrix IR extensions on the back panel. Use the
extension jacks as described and affix the IR RX near or on the Video Display frame or stand
within direct line of sight with the hand held remote. The IR signals are routed to each display,
1 through 4, so as to not interfere with other receivers that may pick up the IR signal.
4) Connect the IR TX emitter cables into Matrix emitter outputs on the front panel. Take note
that the emitter must be affixed over the source IR window. Sometimes finding the IR window
on a source can be a challenge. In order to find the proper placement, move the emitter
carefully over the source
Note: Do not affix the emitter until the placement is tested.
5) Power up all units, the matrix, sources and displays.
6) Use remote or select the button on the front panel to choose the desired input source.
7) Turn on the desired display and note the correct HDMI input must be chosen on the display.
8) The IR TX signals on the front panel are common. Any IR RX signal is will pass through all
4 “IR TX” outputs to the source and the MATRIX controls.
9) Using the SOURCE-SINK Dip Switch. This function applies to a situation when the source HDMI
version exceeds the Matrix HDMI version. This feature can be used to fix most handshake
issues between the source, Matrix and displays. For example: When the TV is HDMI 1.2 version and DVD source is HDMI 1.3 version, it will output HDMI 1.2 version. There are two
modes within the Matrix to update the EDID data according to the DIP setting. When the DIP
is in (0, 0, 0) it is in default MIX mode. Default will automatically output in HDMI 1.2 ver
signals (1080i/1080P and 2CH stereo audio). In most situations, the default mode is ideal
for the application.
until the IR signal makes the source function as required.

EXAMPLE B:
When the source is a HDMI 1.3 version and OUTPUTS 1 through 4 are connected to displays that
can only support HDMI 1.2 versions, simultaneously press “OUTPUT 1” and the “lock key”.
Regardless of whether the HDMI OUTPUT port is connected to a display that supports HDMI 1.3
or not, it will automatically output HDMI 1.2 signals based on the displays max capabilities.
RESETTING THE MATRIX TO FACTORY DEFAULT
The method to reset the Matrix to all default settings is easy. Make sure the dip switches are set
to (0, 0, 0). Disconnect all HDMI the inputs and outputs. Press “OUTPUT 1” and the “lock key”
simultaneously for at least 3 seconds. All EDID settings of all the four input sources will be reset
to the default setting. The default EDID is 1080P and stereo 2 CH audio.

Note 1: The matrix will mix the EDID data of the sink devices. The mixed EDID data will use the
lowest resolution of the video and the least number of channels for audio. For example, some
devices support 1080P, some devices only support 1080i, some support 5.1 audio, but some
only support stereo. Then the mixed mode EDID will be 1080i and stereo.
Note 2: If user wants to just use one sink device’s EDID data, this DIP setting can be used (0, 1, 1).
Sink Mode, USE the EDID of the OUTPUT 1 see Note 2 below
