c) Connect up to three (3) HDBT Receiver(s) to the HDBT Link output port(s) of the
HDMI 4x4 Matrix Switch, with a UTP Cable.
d) An AVR amplifier with a TOSLink Optical Cable may be connected using the
SPDIF output port.
e) Self-powered speakers may be connected to RCAJacks (L&R) output port using
an audio cable.
f) Connect the controlling device (e.g. PC) to the RS232 Input port of the HDMI
4x4 Matrix Switch, with the supplied RS232 cable.
g) Connect a Patch cord from the router to the Ethernet port on Matrix Switch to
control the Matrix Switch using TCP/IP protocol or a WEB GUI.
h) Connect an IR Sensor to the IR Sensor port, and an IR Emitter to the IR Emitter
port. The IR signal can be transmitted bi-directionally between the HDMI 4x4
Matrix Switch and the HDBT Receiver(s).
i) Connect the included DC 24V power adapter to the power port of the 500412.
Note:
1. Connect the HDBT ports of the Matrix Switch and far-end HDBT Receiver with
straight-through cable.
2. IR Sensors connected to the IR Sensor Inputs should support a carrier-wave signal.
If the IR sensor does support carrier-wave then, send the command “%0900.”to
activate native carrier mode. However, if the IR sensor does not support
carrier-wave, then send the command “%0901.”to activate and force the IR Matrix
to send a carrier-wave signal to the far-end HDBT Receiver.
4.4. Connection with the HDBT Receiver
The Matrix Switch has 3 HDBT outputs which support PoC technology. Connect a Cat
5e/6 patch cord to the HDBT Outputs and connect it to the pre-installed infrastructure.
Connect HDBT Receivers to the pre-installed cabling via additional patch leads. Plug
the power supply in to the power socket on the matrix, the HDBT Receivers will be
powered by the 500412 Matrix Switch.

System Operations5.
5.1. Front Panel Button Control
The HDMI 4x4 Matrix Switch can be controlled via the front panel. Please follow the
basic programing instructions below:
1. To connect one input to an output:
Example: Input 1 to Output 3
→Press the Output 3 button until the Input 1 LED is ON
NOTE:
Default status, on first boot up this matrix assigns the IR outputs to the
corresponding HDMI input, meaning, IR out 1 is directly associated to HDMI
input 1 and so on. When you switch an HDMI input to a different output, the
corresponding IR OUT will be switched synchronously to allow the IR
commands to be sent from the select zone back through the Matrix Switch to
the source.
2. To connect one input to several outputs:
Example: Connect Input 2 to Output 3 and 4
→Press the Output 3 button until the Input 2 LED is ON
→Press the Output 4 button until the Input 2 LED is ON
3. To connect an input to all the outputs:
Example: Input 1 to all Outputs
→Press the Output 1 button until the Input 1 LED is ON
→Press the Output 2 button until the Input 1 LED is ON
→Press the Output 3 button until the Input 1 LED is ON
→Press the Output 4 button until the Input 1 LED is ON
Note: LED Indicators of the pressed buttons above will blink green for three times if the
connections were completed successfully, then the LED will switch OFF. If the
connection failed, they the LEDs will turn OFF immediately.

5.2. IR Control
5.2.1. IR Remote
Connect an IR receiver to the IR EYE port of the Matrix Switch, users can control it
through the included IR remote. Here is a brief introduction to the IR remote.
①Standby button, press it to enter/exit standby mode.
②INPUTS:
There are four (4) Input channel selection buttons. The
corresponding IR signal port switches synchronously
when switching input channels.
③OUTPUTS:
Output channel selection buttons.
④Menu buttons: ALL, EDID, CLEAR and ENTER.
ALL: Select all outputs.
EDID management button: Enables the Input port to
manually capture and learn the EDID data of output
devices.
CLEAR: Cancel an operation in progress, before it
have been completed, such as switching an output
channel. Pressing this button will return the Matrix to
its previous status.
ENTER: Confirms/executes an operation.
By using the IR Remote & HDBT transmission technology, the 4K Home Distribution
Hub Kit supports the following capabilities:
1) Locally control a far-end output device.
2) Control local input/output devices remotely.
3) Control the Matrix Switch, either locally or remotely.

5.2.2. Force Carrier
a) An IR signal received by the Matrix Switch IR In port, which is coming from the
HDBT Receiver with a connected IR sensor, will only be transferred to the Matrix
Switch IR Out port, if the IR sensor connected to the HDBT receiver supports IR
carrier-wave.
b) An IR signal received by the Matrix Switch IR In port, which is coming from a
directly connected IR sensor, will only be transferred to the Matrix Switch IR Out
port, if the IR sensor supports an IR carrier-wave.
Note: If the IR sensor connected to the HDBT receiver or directly to the Matrix Switch
does not support carrier-wave, send the command “%0901.” to force enable infrared
carrier mode (force enable carrier-wave mode). Doing so allows the IR signal to be
transferred through the Matrix Switch to the IR Out port.
5.2.3. Control Far-end Displays while being near the Matrix Switch
Connect an IR sensor with IR carrier-wave to the IR IN port of the Matrix Switch. This
allows a user local to the Matrix Switch to control far-end displays via an IR remote.
In this case, the IR signal is transferred via HDBT over twisted pair to the remote
location. In the case of IR signals going from the source to sink direction, only the
corresponding IR OUT port (with the same port number as the IR In) can emit the IR
control signal to the remote display. Thus IR In 1 to HDBT Receiver 1, IR In 2 to HDBT
Receiver 2, and IR In 3 to HDBT Receiver 3.
See the figure below:
Control a far-end device from a position Local to the Switch
Note: The IR sensor connected to IR IN must support an IR carrier-wave signal.
5.2.4. Control Source Devices near the Matrix from a Remote location
The Matrix Switch supports two internal matrix switches, one for the Audio/Video signal
(AV Matrix) and one for the IR signal (IR Matrix). These two matrices can be switch

independently or together depending on the command used as shown below.
a. The command “[x1]V[x2] transfers the AV (only) signal from the input channel
[x1] to one or several output channels [x2] (separate output channels with a
comma). In this case only the AV Matrix is switched, the IR Matrix is not
switched.
b. The command “[x1]B[x2] transfers the AV and IR signal from the input channel
[x1] to one or several output channels [x2] (separate output channels with a
comma). In this case both the AV Matrix and the IR Matrix are switched. Thus
the IR signal will follow the existing AV connection path for input [x1] and output
[x2].
c. The command “[x1]R[x2] transfers the IR (only) signal from the input channel
[x1] to the output channel [x2]. In this case only the IR Matrix is switched, the
AV Matrix is not switched.
Thus the IR signal path may be different then the AV connection path, depending on the
command used.
In all cases above connect IR sensor(s) to the IR IN port on the far-end HDBT
receiver(s), and IR Emitter(s) to the IR OUT ports of the Matrix Switch. This allows a
user who is remote from the Matrix Switch to be able to control source devices local to
the Matrix Switch. Use the IR remote control of the source at the remote location.
Note: If the IR sensor connected to IR IN of the HDBT Receiver does not support
carrier-wave, then Send command “%0901.” to force infrared carrier-wave mode.
The 4 “IR OUT” ports on the Matrix Switch and the 3 “IR IN” ports on the far-end
HDBT Receivers make up the 4x3 IR matrix. See figure below:
