Installation and Wiring
Installation
Note: Before installation, please ensure the device is disconnected from the
power source.
MX44-4KUHDE occupies 1U space and can be placed on a solid and stable
surface or installed on a standard rack mount.
Steps for installing the matrix on a rack mount:
1. Position and install the mounting brackets with the mounting screws
provided.
2. Mount and affix the matrix in the rack mount with the mounting screws.
Wiring
Before wiring, please ensure the unit is disconnected from power. Otherwise,
circuitry damage or physical injury may occur.
Steps for device wiring:
1. Connect HDMI IN

Connect HDMI source devices to HDMI IN 1-4 of the matrix with high-
quality HDMI cables (e.g. Blu-ray player, PC, game console, Apple TV,
etc.)
2. Connect HDMI OUT
Connect HDMI display devices to HDMI OUT 1-4 of the matrix (e.g. TV,
projector, LED/LCD display, etc.)
3. Connect AUDIO OUT
Connect audio devices to AUDIO OUT 1-4 of the matrix (e.g. audio
amplifier) with RCA stereo cables.
4. Connect for additional control options:
a) IR Control: The matrix can be controlled through IR signal by
pointing the IR remote provided at front panel IR window directly.
Alternatively, connect an IR receiver (38KHz) to IR EXT. of the
matrix for IR extension, and have its head secured in a place
accessible to the matrix remote.
b) RS232 Control: Connect a control PC or control system to RS232
of the matrix.
c) LAN (Web UI/Telnet) Control: Connect the control PC or control
system's network to the matrix through LAN port.
5. Connect the power
Connect the AC power cord provided and switch on the power button.
6. Power on all devices.
Note:
Before plug or unplug any cable, please power off the matrix firstly.
When turning on and off the system, please follow the rule "first off, last
on".

The front panel of the MX44-4KUHDE matrix features a LED screen to display
the mapping status from each input to each output channel.
Power on the matrix and wait until the front panel LED screen shows "1234"
in red. Then the matrix is ready for operation. You can select input from 1 to 4
for each output via front panel buttons.
For example, to select input source for output display:
1. Press the left ( ) or right ( ) button to select output channel. Then the LED
will blink slowly to show the selected output channel.
3. Press the Enter button to implement above selection. The LED will stop
blinking when the selection takes effect.
You can switch among multiple inputs for each output display by pointing the
matrix IR remote directly at the IR window on the front panel or the IR
extension cable connected to the rear panel.

2. Locate the target output you want to switch inputs for on the remote,
numbered 1-4 vertically along the right side.
3. Press the desired input number to select the corresponding input source
for your target output.
4. To cycle through multiple inputs for your target output, press the

EDID Management

EDID (Extended Display Identification Data) is a data structure generated by
a digital display to communicate its capabilities, such as its native resolution,
to the attached source device.
MX44-4KUHDE Matrix provides EDID management to output different video
resolutions and audio channels for the displays based on the switch settings.
By default, the EDID DIP switch is set in Smart EDID position, i.e. all three
switches are set to 1 or down position. When connected to multiple displays,
the video with minimum resolution that ranks among the displays' maximum
resolutions and 2.0ch audio will be set as input EDID.
If any device communication or compatibility issues occur during installation,
please set the DIP switches manually using the following table:

Smart EDID ON (Default)
For DIP setting "000", EDID can be set via front panel buttons, WEB UI and
API commands.
Using front panel control, you are able to copy EDID from an HDMI Output to
the desired HDMI Input. For instance, to copy EDID of HDMI Output 1 to HDMI
Input 2, you should follow steps below:
1. Set the switch to position "000", then press the selection button on the
front panel to select Input 2 for Output 1; the LED will blink.
2. Long press the Enter button for at least 5 seconds. When the LED
window displays "OK", EDID copy setting is successful. Otherwise, "FL-
2" will appear to indicate failed setting.
Note:
If EDID Copy fails, a fixed 1080P@60Hz stereo EDID would be provided
to the source device.
You must reboot the matrix for EDID switch settings to take effect.
Advanced users may need to control the matrix through API commands.
Connect a control system or PC to the LAN or RS232 port of the matrix with
an Ethernet cable or the USB-to-UART cable provided. API Commands are
available in separate document "API Command Set_MX44-4KUHDE".
Telnet Control
1. Connect the LAN port of the matrix to your PC using astraight UTP cable.
2. Set your PC to the same network segment as the matrix, e.g.
192.168.X.X. (X ranges 2~253)
3. Ensure Telnet Client and Telnet Server features are enabled on your
computer.
API Command Control

4. Connect between the control PC and matrix through telnet.
a) Launch the Run window on your computer, enter "CMD" in the
textbox, and then click "OK".
b) The following DOS window will pop up.
Input "telnet 192.168.10.254" and press Enter.
c) A new window will display and show "Welcome to use matrix telnet",
indicating telnet connection between the matrix and computer is
