9.1 Software control
Connect the 4x4 Matrix to PC with a RS232 cable (see pinout table on page 7), open
the software "PC Tool" included with the download of this manual. On the COM Setting
session, select the COM port according to your PC and click "Connect" to get connected.
On this COM setting session, you can also change the Device name, Device name
supports up to 16 characters. Save or edit your status by clicking the "Edit" button.
Come to Port Set session to select or switch your input sources for each output. We can
read the current status by clicking the “Status” button, or Clear our historical operating
record by clicking “Clear” button. The right down blank shows the operating history.

Operating Instruction
The EDID session helps us to Read and Configure EDID for each input, such as HDR, 3D,
Data rates and Audio channel.
Picture 2: EDID Setting
The IP configure session helps to read and configure the IP address and MAC of
the Matrix. Click DHCP if you want the router to automatically assign an IP for the Matrix,
then click "Save IP Config". Otherwise, you can assign network settings manually here.
After doing so, click "Save IP Config" to have them take effect.
Picture 3: IP Config

The Net Config section allows us to configure the PC and the Matrix (provided they are in the same LAN) with the IP
Address and make a connection.
If you don't change the default settings, the Host (Matrix) IP address is 192.168.1.168.
If you wish to change the Network Settings, make the changes on the screen under "IP Config", and then click
"Save IP Config" (see Picture 3).
If you want to have a DHCP server apply settings, click the box next to "DHCP", and then click "Save IP Config"
(see Picture 3). Wait at least 5 minutes for the IP Address settings to update to what the DHCP server assigns.
(The setting blocks will also gray out so that you cannot edit them.) Then enter the displayed IP address into your
browser to open the control interface (Page 14, Picture 11).
Use the Discovery Feature to Identify the IP address assigned by the DHCP server
Note: This is only truly useful if you have
multiple Matrix Switches connected to the
LAN and need to know what IP address is
assigned to each.
1. Under "Net Config" ("1" right), the address
and port number of your PC connection should
already be shown under "Current PC
Information". Click "Connect" ("2" right) to the
right of that information.
2. The Host Device Information section will be
shown. Click "Search Device" ("3" below).
The IP address and Matrix switch name for any
Matrix Switches connected to your subnet will be
displayed.
3. If there are more than one connected to the subnet, make sure the Matrix you want to control is indicated under
"Set Device Number" ("4" below), and click "Connect" ("5" below) next to the Host Device IP Address.
4. To open the web interface for the Switch to control it, either go to your browser and enter the IP address shown,
or, click the "IE" button ("6" below) and the PC's default browser will open automatically to that IP address.
