Warning:
If you want to change the IP, please be aware of the following:
First: Connect to the network by the current IP (192.168.00.110, Same as the host PC).
Second: If you want to change the IP to 192.168.000.100, order input: 192.168.000.100: 3205 (Only the back end digit can be changed).
Third: Turn off the controller and restart, connect with network by new IP(192.168.000.100).
Forth: If something goes wrong, reset by input order: SFACT# or pressing the button “+””-“at the same time for 1 second. IP will be reset(192.168.00.110).
