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.
Use ethernet cable, Daniel P/N 3-3400-079, to connect the PC to the meter.
A DIN 41612 48-pin connector is the interface from the CPU Module to the Field Connection
Board (male end located on the back of the Field Connection Board).
