Ethernet Pixel Controller Connection Issue

[Craig]

Have you changed the ip address of your PC to be in the same network range as the default ip address of the controller? Basically the first 3 numbers of of you PCs ip address must match the controller ip address. 4th number should be different I.e 192.168.168.100
Once you have connected to the controller you can change its ip address accordingly to suit your network settings and change your PCs ip address back.
