IP Address Configuration

The LS8000-3 can automatically obtain a network address using DHCP (Dynamic Host Configuration Protocol), or it can use a manually configured IP Address. If DHCP is enabled, then the LS8000-3 will reports its IP Address as

0.0.0.0until an address is acquired, at which time it will report the address obtained from the DHCP server. This process usually only takes a few seconds, but the time will depend on the DHCP server's responsiveness. If the IP Address stays at 0.0.0.0 for more than 5 minutes, this means that the LS8000-3 was unable to acquire a network address, and you should either use a manual IP Address, or contact your network administrator to determine the cause.

DHCP

The LS8000-3 DHCP client supports the Host Name Option (see RFC 2132.) If the network's DHCP server and DNS server support this feature, the DHCP server will register this name with the DNS server, making the LS8000-3 visible on the network by the Host Name as well as by the IP Address. This allows you to communicate with a gauge over Ethernet without having to know its IP Address.

The DHCP lease on the IP Address usually expires after some amount of time, requiring the LS8000-3 to re-register. Usually, the same IP Address will be returned by the DHCP server, but this is not guaranteed. If you are reading measurements from the LS8000-3 over Ethernet, you may want to permanently fix the IP Address by assigning it manually.
