Ethernet communications
The Ethernet port IP address, subnet mask, and gateway address are software-
configurable. In addition, a meter can be configured to act as a DHCP (Dynamic Host
Configuration Protocol) server to assign an IP address to a PC or laptop running Daniel
MeterLink. The DHCP server facility is not intended to act as a general purpose DHCP
server for a wider network. To this end, no user control is provided over the class or range
of IP addresses the unit provides. A standard twisted pair (Cat-5) cable should be used for
Ethernet wiring.
It is strongly recommended that the meter be configured using an independent (off-
network) single host. After configuration of the Daniel 3410 Series Gas Ultrasonic Flow
Meter, the DHCP option must be turned off if used on a LAN/WAN.
NOTICE
RESTRICTED ETHERNET AND SERIAL CONNECTIVITY USAGE
Failure to restrict Ethernet and communication access to the Daniel 3410 Series Gas
Ultrasonic Flow Meter can result in, among other things, unauthorized access, system
corruption, and/or data loss.
