▪LAN (10 m/100 m), RS232 are for PC control.
▪Analog Audio IN/OUT ports are bond with corresponding HDMI ports.
For example, if INPUT HDMI 1 signal is DVI, matrix will use Analog AUDIO IN 1 as HDMI 1 audio source.
Note: Analog AUDIO IN is only available when the corresponding video input is DVI signal.
Analog AUDIO OUT n will always output the same audio content with HDMI OUTPUT n Analog Audio IN/OUT
connection.
▪IR IN and IR OUT
IR IN/OUT is for remote control routing, and followed with video routing,
For example, if input HDMI m is routed to output HDMI n1 and n2 ports, then IR IN n1 and n2 ports will be routed
to IR OUT m port. Please refer to bellow illustration.

4.3.2 Network Control
Direct connection via Ethernet cable
Control steps as follows:
1. Connect the PC and device directly via an Ethernet cable.
2. Manually setting up the IP address of the PC, and the IP address of the PC and the device should be in a same
network segment (The default IP address of the device is 192.168.0.247, and the default network mask of the
device is 255.255.255.0). The screenshots of setting up the IP address are as follows:

Figure 1: Manually setting up the IP address of the PC
3. Run the PC control software (If the IP address of the PC changed after running the software, you should close
it and run it again.)
4. Click to switch "Ctrl Mode" to "Network".
5. Click the "Search Device" button.
6. Click the device you want to control in the result list (When you click it, the software will read the network
configuration such as network port and so on of the device automatically.)
7. Click the ‘Disconnected’ button (which is right to "Status") to connect to the device.
8. If connected successfully, "Disconnected" button will show "Connected".
The UI after connected successfully will be as follows:
▪Connection via LAN

Control steps as follows:
1. Connect the PC and the device to a same network router.
2. Setting up the IP address of the PC. Either manual (Static) mode or automatic (DHCP) mode is ok. Just make
sure the IP address of the PC and the device are in a same network segment. When the IP type is obtained
automatically, the network router that PC and the device connected to should support HDCP function.
3. Run the PC control software (If the IP address of the PC changed after running the software, you should close
it and run it again.)
4. Click to switch "Ctrl Mode" to "Network".
5. Click the "Search Device" button.
6. Click the device you want to control in the result list (When you click it, the software will read the network
configuration such as network port and so on of the device automatically.)

Step F: When the tool shows message with "Success", Click "Search Device" button to search and load configuration
again to make sure your modification saved successfully.
NOTE:
1. Select the device, and it will display the matrix network board information. User can edit the device name, in
order to better identify matrix. User can set dynamic IP/ static IP, subnet mask, gateway, and other network
information. At the same time, user can also set the device port. Serial port baud rate is 9600 (the user
cannot change the baud rate, otherwise it will lead to the network control failed.).
2. Configuration via UART only support modify IP address or IP address type. If you want to modify another
configuration, please configure it via Network.

edit the input 1 name to set-top box). User can also edit the output name to show which sink is connected
(for example, the output 1 users can edit the name to TV.)
2. Support scene save (the user can pull down the corresponding drop-down menu, to save the current input
and output relationship to mode X, support 8 different modes.)
3. Support scene recalls (the user can drop down the corresponding drop-down menu, to set the mode X input
and output relationship to the matrix.)
4. Support one input output to all outputs (the user can drop down the "All set" drop-down menu, to set the
input X output to all the output ports)

select the device that found. Click Open Website to open the web control web site, or can input the IP on the web
browser, then enter the username: admin Password: admin, then can control the matrix switch function and use the
website.
NOTE: The computer IP and matrix IP must be in the same segment and the same local area network. For example,
the matrix IP is 192.168.1.xxx, then the computer IP must be 192.168.1.yyy. Otherwise need to change the matrix IP or
the computer IP. The browser must support HTML5 feature, which must be IE10 and above.
If the matrix IP address is known: Input the IP on the web browser, then enter the username: admin Password: admin,
and then can control the matrix switch function and use the website.
