Node
Help Overview |
The
default setting of "Auto-Discovery" permits the Node to
broadcast a 70-byte self-identification message over the LAN every
15 seconds, a very light load on the network. This method has the
advantage that the Nodes can discovery each other's IP Addresses,
thereby greatly facilitating network setup and maintenance. The alternate "Stealth Mode" setting precludes broadcasting by the Nodes. This setting should only be selected if such broadcasting is not allowed by IT department policy, as it does not allow the Nodes to discover each other's IP Addresses. However, IP addresses can still be discovered by our PC-resident Node Manager software. Click on the radio buttons to select either "Auto-Discovery" or "Stealth Mode." Press GO to enter your selection. 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. |
