Dynamic IP (Obtain IP Address from a DHCP server)

By selecting Dynamic IP, the Controller will act as a DHCP client and obtain its LAN IP settings from the DHCP (Dynamic Host Configuration Protocol) server on the local network

Static IP (Assign a Fixed IP Address, Mask, Gateway and DNS)

If necessary, you can assign a static IP address to the Controller. The IP address of each device on the local area network must be within the same IP address range and subnet mask. For a small subnet with less than 253 IP addresses assigned (e.g. Class C private IP), each device on the LAN (Local Area Network) needs have a unique IP Address in the format of (example) 192.168.0.x to connect to other devices within the same network.

Subnet Mask

Specify the subnet mask for the Controller. The Subnet mask must be the same for all devices on the same subnet of the network. The default subnet setting is 255.255.255.0. For a small subnet with less than 253 IP addresses assigned (e.g. Class C private IP), keep this default setting.

Gateway IP Address

Specify the Gateway IP Address for the Controller. The Gateway IP Address is almost always the LAN address of your router.
