Help Overview |
Use the HTTP Port
to change the HTTP port number of the
Node if
required. Leave the HTTP number at 80
unless you have a reason to change. Press GO to enter any
change. By default, port 80 is used by URLs that begin with http:// and is the default port number for HTTP communications. Port 443 is used by URLs that begin with https:// . Only enter port number other than 80 if that number has been blocked by the IT department and a different number has been supplied. If the port number is changed to anything other than 80, all web addresses that reference the Node must include that port number. 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. |
