Communicating
with the
Instrument
The RJ-45 connector on the instrument marked "RS-485" in Figure 4-3
may be used to connect the unit to a desktop or laptop PC COM port
when the distance to the instrument is greater than 50 feet. It is,
however, specifically designed to connect the REMOTE 3104P or
5104P to a MODBUS RS-485 network. Whenever possible, it is
prudent to use the USB port for connection to a PC.
WARNING:
Only one
port may be used at a
time. The instrument
must be powered OFF
before changing from
USB, Ethernet or RS-485
to any other port.
