Introduction
Overview
This product is an 8x8 HDMI Matrix with 4K@60 4:4:4 8bit, HDR10, HLG &
Dolby Vision and HDCP 2.2 compatibility. It allows eight sources to be
switched to any of the eight displays simultaneously. The matrix also provides
analog and digital audio output ports, which can be set to output
de-embedding audio or ARC audio from the associated HDMI output. It also
supports 4K to 1080P down scaler for each output when it is connected to
1080P TV.
It can be controlled by front panel buttons, IR, RS232 and LAN control with
Telnet API and Web UI.
As a compact 1U stand-alone 8x8 HDMI Matrix, it offers the convenience of
future-ready Ultra HD A/V switching and distribution solution.

Front Panel Control
Basic switch of input sources to output displays and matrix IP address can be
achieved by using front panel buttons.
Power on matrix and wait till the front panel LED shows the input channel
numbers correspond to output channels. Then the Matrix is ready for
operation.
To select input source for output display:
1. Press the Left (◄) or Right (►) button to select output channel. The
LED blinks to show the selected output channel.
Output SelectionBlink
2. Press the Up (▲) or Down (▼) button to select input channel. If the LED
shows "-", the output is closed.
Input Selection
Blink
3. Press the Enter button to confirm the selection. When the selection
takes effect, the LED stops blinking.
Enter Button
To display matrix IP address on LED indicator:
(Suppose the IP address of the matrix is 192.168.11.143)
Hold down the Up (▲) and Down (▼) buttons simultaneously for at least 3
seconds and then release, the LED indicators will display the matrix IP
address “192.168”, “.011.143” in sequence for 3 times.
To copy EDID:

10
1. Press the Left (◄) or Right (►) button to select output channel. The LED
blinks to show the selected output channel.
2. Press the Up (▲) or Down (▼) button to select input channel. The LED
still blinks.
3. Hold “Enter” button for at least 3s to copy the EDID of the display
connected to the selected output port to the selected input source.
4. If EDID copy is successful, the LED indicators will show “CPY OK”. If
copy fails, the LED indicators will show “CPY FAIL”.
Note: When copy EDID fails, if the corresponding output port is not
connected to a display, the input EDID will be the previous effective EDID
value; if the EDID of the connected display is damaged, the input EDID will
be the default value.

IR Remote Control
The Matrix can be controlled by the IR Remote provided. Point the Remote
directly to the Matrix, now you can select input source for each output display.
Next Input
Previous Input
Output 2
To select input source for output display:
1. Locate the target output you want to switch inputs for, numbered 1-8
vertically in the middle.

System Code Switch
The IR Remote provided with the Matrix is shipped in "00" IR system code. In
the event that Remote's IR signal interferes with IR devices, e.g. TV, DVD

12
player, the Remote can be switched to "4E" code by short pressing the
System Code Switch on the Remote panel. At the same time, you may
redefine the IR system code of the Matrix using the API command or Web UI.

communication. Connect a control PC or control system to the RS232 port of
the receiver. API command for RS232 control is available in the separate
document “ API Command Set MX88-4KUHDE.2 ”. A professional RS232
serial interface software (e.g. Serial Assist) may be needed as well.
Before executing the API command through RS232 serial connection, please
ensure RS232 interface of the device and the control PC are configured
correctly.

Web UI Control
The Web UI designed for the matrix is available for basic controls and
advanced settings of the device. The Web UI can be accessed through a
browser with latest version, e.g. Chrome, Firefox, Safari, Opera, IE, etc.
The default network mode of matrix is DHCP, if it isn’t connected to a DHCP
server, the matrix supports for local 169.254 IP address.
Get Access to the Web UI
1. Connect the LAN port of the matrix to your PC using a straight UTP
cable, or connect the matrix to a local area network, and connect your
PC to the same network.
2. Get IP address through pressing front panel buttons (see “Front Panel
Control” section) or sending API commands (see the separate
document “API Command Set_ MX0808-1022-000”). Set your PC to
the same network segment as the matrix if you connect the matrix to
your PC directly.
3. Input the IP address in your browser and press Enter. The following
window will display.
• To implement basic video and audio control of the matrix, click “User” to
login as User. When login as User, no password is required.
