C.2 Ethernet cable to PC communication
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 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 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 3410 Series Gas
Ultrasonic Flow Meter can result in, among other things, unauthorized
access, system corruption, and/or data loss.
User is responsible for ensuring that physical access and Ethernet or
electronic access to the 3410 Series Gas Ultrasonic Flow Meter is
appropriately controlled and any necessary security precautions are
implemented; such as, establishing a firewall, setting password permissions
and/or implementing security levels.

Serial communications
Use a serial cable, to connect to a PC running MeterLink™. The cable is
designed for RS-232 communications which is the serial Port A default
configuration (see 3410 Series engineering drawings Systems Wiring
Diagram, Drawing DMC - 005324).
The DB-9 end of the cable plugs directly into the PC running MeterLink. The
three wires on the other end of the cable connect to the CPU Module
RS-485/RS-232 terminals. The RED wire goes to RX, the WHITE wire goes to
TX, and the BLACK wire goes to COM (see Table 3-5 for Port A wiring).
RS-485, 2-wire connection on Port A, uses TX+ and TX- on the CPU Module
and has a ground wire.
When Belden wire No. 9940 or equivalent is used, the maximum cable
length for RS-232 communications at 9600 bps is 88.3 meters (250 ft.) and
the maximum cable length for RS-485 communication at 57600 bps is 600
meters (1970 ft.).
June 2022 Retrofit Instructions
Port A supports a special override mode which forces the port to use known
communication values (19200 baud, address 32, RS-232). Note that the
protocol is auto-detected. This mode is expected to be used during meter
commissioning (to establish initial communication) and in the event that the
user cannot communicate with the meter (possibly due to an inadvertent
communication configuration change). Alternately, when using MeterLink
with an Ethernet port, use Ethernet cable, to connect the PC.
