Use the Subnet Mask field to enter the subnet mask for your LAN's gateway router if you want to be able to address Nodes on the LAN  from anywhere over the Internet and if a subnet mask entry has been requested by your organization's IT department. A subnet mask is a way of telling your router which network addresses it can consider local and which are remote.

Leave at 0.0.0.0 to disable the subnet mask feature. Press GO to enter any change.

Background:  Each Node has an IP address. This is a 4-byte number (e.g., 192.168.0.57) which is used to address Ethernet nodes on a local area network (LAN) or on the Internet (WAN). An IP address can be static and public so that it can be addressed on a WAN and have an associated domain name. It can also be a dynamic address assigned by a router or other DHCP server on a LAN. Such an address is also called a private or local IP address. Our Node-resident firmware automatically discovers the IP address of all Nodes on a LAN or WAN, plus any devices connected to each Server Node via an RS485 bus.
