RS-232 Communications
The instrument can use RS232 as a communication mode by using the
optional USB to RS232 Converter cable. The cable is connected to the
RJ-45 Port on the Remote and to any USB port on a PC.
Windows will detect that a new hardware device has been attached and
will finalize the installation as needed. This is a routine “registering” of
components that should only take a moment. An additional COM port
will be added to the PC.
Configuring
with REMOTE
Display
The instrument can be completely configured using the optional
REMOTE Display touchscreen interface.
DIP Switch 7 must be ON before connecting the Display and powering
on the instrument.
Please consult the REMOTE Display Operating Manual, LWS PN
248083285-1, for detailed information.
Configuring
with the
MODBUS
Protocol
Alternatively, the instrument can be configured using the MODBUS
protocol.
When you power up the instrument, the pump will automatically turn
on after 5 seconds, and it will begin sampling using the default
configuration:
• Location = 0
• Sample Time = 60 seconds
Note:
For the full
MODBUS register map,
please refer to Appendix A.
• Hold Time = 0 seconds
• Initial Delay = 0 seconds
Note:
The automatic
starting of the sampling
accommodates systems
that do not send a START
command, but just polls
the instrument for its data.
To stop the pump and the sampling, send the command 12 to command
register 40002.
