9. Web GUI UserGuide
The MX44KT can be controlled by Web GUI. You will need to know the IP address of the MX44KT. This can be done with a PC or with a network scan app. The network scan app will return "Simplified-MFG-MX44KT" in the results
Step 1: Get the current IP Address with your PC.
The default IP address mode is DHCP. You can get the current MX44KT IP address via RS-232 control. Send the ASCII command "r ipconfig!" through a Serial Command tool, then you'll get the feedback information as shown below:
IP Mode: DHCP
IP:192.168.2.209
Subnet Mask:255.255.255.0
Gateway:192.168.2.1
TCP/IP port=8000
Telnet port=23
Mac address:6C:DF:FB:07:1C:E2
IP:192.168.2.209 in the above figure is the current MX44KT's IP address (this IP address is variable, depending on what the router assigns as the matrix is preset to DHCP).
For the details of RS-232 control, please refer to "10. RS-232 Control Command".
Step 2: Connect the TCP/IP port of the MX44KT to a LAN or PC with an UTP cable (as shown in the following figure) and set the IP address of the PC to be in the same network segment with the MX44KT.

Step 3: Input the current IP address of MX44KT into your browser on the PC to enter Web GUI page.


After entering the Web GUI IP address, there will be a Login page, as shown below: Select "Admin" from the list and enter the password. The default passwords are:
