1.0 Matrix System Overview
1.0.1 Introduction
HX-2388 Matrix Switcher is high performance HDMI switching equipment combining with
video and audio. It is used for input/output cross switching of image signals. Through 8
separated HDMI sources, you can also transmit images input separately to each
multi-output equipments, thereby minimizing signal attenuation and ensuring high
definition, integrating high fidelity graphics and audio signal output. Besides HX-2388
Matrix switcher is unlike typical HDMI switchers only communication limited the distance,
through the HDMI-EP devices, you can over long distances to transmit signals.
HX-2388 Matrix Switcher is used mainly in TV broadcasting projects, multi-media
conference halls, and large display projects, TV teaching and command control centers.
It boasts features of power interruption protection during power surge, LCD display and
synchronous and integrate audio/visual switching functions. HX-2388 supports 8 HDMI
Type A or RJ-45 for input and output connectors. Beside it also supports a RS-232 or
LAN communication port enables convenient communication with remote control
equipment to switch the image signals.

7.0.2.1 RS-232 Main Operation Interface
Refer to the main configuration screen as above, the marked blue area shows crossing
matrix of output ports 01-08 and input ports 01-08. For the basic operation is described
as below:
Examples for Selecting Matrix Switching Functions:
Example: Now there is an HX-2388 matrix having all the input/output ports properly
connected to the equipment. If you want to set channel 1 input to channel 2, 3 and 4
output; channel 3 inputs to channel 1 output. There are 2 ways to implement the
switching. Please follow the ways and steps to finish the switching functions:
First way: Make sure you have selected “Video” check box ( ). Directly click on
the corresponding icons on the matrix to transform them into to complete the
switching operation.
Second way:
Step 1: Make sure you have selected “Video” check box ( ).
Step 2: First select the “Output” number keys 02, 03 and 04 to the right of the blue
configuration area, and select the “Input” number key 01 to the bottom.
Then, press consecutively the previously selected “Output” number keys 02,
03 and 04 (or you can press the “Deselect all output” key). This way, you
have selected “Input” 01 and “Output” 02, 03 and 04 switching.
Step 3: First select the “Output” number key 01 to the right of the blue configuration
area, and select the “Input” number key 03 to the bottom. Then, press the
previously selected “Output” number key 01 (or you can press the
“Deselect all output” key). This way, you have selected Input 03 and
Output 01 switching.
Upon completion of the above 3 steps, you have actually completed the switching
operation of having channel 1 input to channel 2, 3 and 4 output while at the same time
successfully switched from channel 3 input to channel 1 output.
The main configuration screen also shows you some function buttons to easy operation:
Disconnect: To disable the connections.After you had configured the connection
between input and output ports, you can click this button to disable the connections.
Select all output: Click this button to select all output ports including output 01~08.
Deselect all output: Click this button to cancel presently selected output ports.After you
had configured a connected combination, please click this button firstly for next settings.
Disconnect all: To stop all the connections.
Scan: To search the device controlled by the RS-232 Software Configuration. When the
device name located on the left of the main configuration screen is empty, you can click
