Power on or Standby:
Input 1/2/3/4/5/6/7/8:
◀ ▶:
Output 1/2/3/4/5/6/7/8:
ALL:
Power on the Matrix or set it to standby mode.
Press these buttons to select the input signal source.
Select all output channels simultaneously. For example, when
you press the “ALL” button and then press INPUT “1” button,
at this time the input “1” source will be output to all display
devices.
The first way: The IR window accepts the IR remote signal. When using the IR remote,
the furthest distance is 7 meters and the angle is ± 45°. The diagram is shown as below:
The Matrix supports selecting input and output channel by using the IR remote. There
are two ways to receive the IR remote signal.
Press these buttons to select the signal output channel.
Select the last or next signal input channel.
Operation Instruction: You need to press the Output button first and then press the
Input button to select the corresponding input source. For example, press Output-X (X
means the output button from 1 to 8, including “ALL” button), then press Input-Y (Y
means the input button from 1 to 8).

The second way: If the IR receiver window of the Matrix is blocked or the Matrix is
installed in a closed area out of infrared line of sight, the IR receiver cable can be
inserted to the “IR EXT” port to receive the IR remote signal. The furthest distance of
using the IR remote is 7 meters and the IR remote is directly faced to the IR receiver
head. The diagram is shown as below.

IR Control System
The product supports one-way IR matrix function. When Matrix is connected to CAT
Receiver through CAT6 cable, you can control the input source device (local end) by
the IR control signal from the CAT receiver (remote end). For example, the HDMI output
signal on the CAT Receiver 4 is from the HDMI IN 4 port, so IR input signal of the CAT
Receiver 4 will be emit to IR OUT 4 port of the Matrix. The HDMI output signal on the
CAT Receiver 6 is from the HDMI IN 6 port. Then, IR input signal of the CAT Receiver 6
will be emit to IR OUT 6 port of the Matrix etc. The IR OUT signal of the Matrix depends
on your IR remote of source device. Please see the following connection diagram.

EDID Management
This Matrix has 21 factory defined EDID settings, 2 user-defined EDID modes and 16
copy EDID modes. You can select defined EDID mode or copy EDID mode to input port
through RS-232 control or Web GUI.
RS-232 control operation: Connect the Matrix to PC with a serial cable, then open a
Serial Command tool on PC to send ASCII command “s edid in x from z!” to set EDID.
For details, please refer to “EDID Setting” in the ASCII command list of “RS-232 Control
Command”.
Web GUI Operation: Please check the EDID management in the “Input page” of “Web
GUI User Guide”.

The Matrix can be controlled by Web GUI. The operation method is shown as below:
Step 1: Get the current IP Address.
The default IP address is 192.168.0.100. You can get the current Matrix IP address via
RS-232 control. Send the ASCII command “ r ipconfig!” through a Serial Command tool,
then you’ll get the feedback information as shown below:
IP:192.168.62.109 in the above figure is the IP Address of the Matrix (the IP address is
variable, depending on what the specific machine returns).
For the details of RS-232 control, please refer to “RS-232 Control Command”.
Step 2: Connect the TCP/IP port of the Matrix to a PC with a UTP cable (as shown
in the following figure), and set the IP address of the PC to be in the same network
segment with the Matrix.
Step 3: Enter the IP address of the Matrix into your browser on the PC to enter Web
