Communication
Modes
The default communication mode for the REMOTE-4PN series is
MODBUS TCP over Ethernet. An alternative is MODBUS ASCII
over Ethernet.
Communicating with the Instrument
The RJ-45 connector marked "Data Port" shown in Figure 4-1 is used
to connect the unit to a port of a desktop or laptop PC or to an RS485
MODBUS or Ethernet network with the appropriate cabling or adapter.

Data Port
The Data Port RJ-45 connector provides RS485 signals. Changing the
instrument communication mode requires changing its physical
configuration. If the LWS Network Adapter will be used to attach the
REMOTE4-PN to an Ethernet network or the instrument must operate
in a mode other than RS485 MODBUS, contact Lighthouse Technical
Support for more information. Table 4-1 and Table 4-2 illustrate RJ45
pins and the signals assigned.
