3. MODBUS Over Ethernet. This group of settings is used to set the parameters for the MODBUS TCP mode. The
MODBUS TCP server should always be located on port 502 as per MODBUS specifications.
4. Network Settings. This group of settings is used to configure the TCP/IP stack for the Ethernet interface. Default
is DHCP, which causes the RMU5 to attempt to obtain its settings from a DHCP server on the local network
segment. If "Use DHCP" is unchecked, then the individual parameters may be changed. Network settings
parameters should be obtained from the administrator of the LAN segment to which the RMU5 is being attached.
