ring lugs. Fasten ring lugs with the 10-32 bagged hardware (flat washer, lock washer,
and nut) provided. DO NOT OVERTORQUE. HAND Tighten with a standard nut
driver. 12 inch-pounds (1.36 N-m) is recommended, MAXIMUM torque is 15 inch-
pounds (1.69 N-m).
Current inputs, option 5: 5 Amp input with internal current isolation transformer,
constructed with 10-32 studs as the current terminals. (See Figure 3A for the
physical construction shown for the current terminals). It is intended that this
meter connect to the output from the secondary of permanently installed Current
Transformers (CTs).

3.4 Serial Ports (See section 4.2)

The M350 meters are equipped with an optional serial port. The port is software
(user) configurable for RS-232 or RS-485. The RS-232 drivers support full and half
duplex modes. See Figures 7-8 for signal assignments.

3.5 Ethernet

The M350 Ethernet port meets or exceeds all requirements of ANSI/IEEE Std 802.3
(IEC 8802-3:2000) and additionally meets the requirements of part 8-1 TCP/IP T-
profile for physical layer 1 (Ethernet copper interface).
M350 meters are offered with a standard Ethernet 10/100 Megabit (Mb) RJ45 (copper)
interface (10BASE-T and 100BASE-TX) which automatically selects the most
appropriate operating conditions via auto-negotiation. This interface is capable of
operating either as half-duplex (compatible with all Ethernet infrastructure) or full-
duplex interfaces (which allow a potential doubling of network traffic). Note that the
meters come with the port setup as a service port, with Modbus TCP/IP or DNP3
TCP/IP or UDP software offered as an option. An option to replace the standard RJ45
port with a LC 100BASE-FX fiber port also exists operating at 1300 nm (far infra-red,
full-duplex). If needed, adapters are available to convert the LC to ST connectors, the
same that are used in the Bitronics 70 Series.

3.5.1 Network settings

The M350 meters come preconfigured for interconnection to an HTML web server with
default settings for IP address, SUBNET mask, and ROUTER (GATEWAY) address.
