• Ethernet 1 is an RJ-45 connector designed to accept common
Ethernet cable connections found on computers and other
Ethernet enabled devices and is primarily intended for local
connection to a computer, but can also be permanently
connected to other Ethernet devices.
• Ethernet port 2 is a field terminated port primarily intended for
connection to supervisory systems or other Ethernet enabled
devices.
• Both ports can be used for MODBUS TCP communication and
communication to the MON2020 configuration and diagnostics
software.
• To configure the Ethernet ports after power has been applied,
refer to
“Connect to Ethernet ports” on page 3-37 .
3.11.1 Ethernet port 1
Ethernet port 1 was designed primarily for local connection to a
computer, such as a technician's laptop, for occasional maintenance
and diagnostic purposes. The connector is the same RJ-45 Ethernet
connector commonly found on most Internet-capable devices.
The RJ-45 port has a DHCP server that will automatically assign an
Internet Protocol (IP) address to a computer when it is connected to
the port. There is a switch at SW1 on the back plane that turns the
server on and off.
NOTICE
If your computer is not configured to automatically configure Ethernet settings,
contact your IT department for instructions on how to change your IP settings to an
address in the same range as the Ethernet subnet on the GC, or to obtain an IP
address and subnet for the 370XA that will work with your computer's settings.
If Port 1 is to be wired to other Ethernet-enabled devices, such as a
router, hub, or local area network, then set the DHCP server switch to
OFF to ensure that the operation of the network is not affected.
