through an ASCII Command tool, then you’ll get the feedback information as shown below:
IP:192.168.62.109 in the above figure is the IP Address of the Matrix (the IP address is
variable, depending on what the specific machine returns).
For the details of ASCII control, please refer to “10. RS-232 Control Command”.
Step 2: Connect the TCP/IP port of the Matrix to a PC with an UTP cable and set the IP
address of the PC to be in the same network segment with the Matrix.
