WARNING:

Lighthouse Technical
Support for the correct
instrument configuration
BEFORE attempting to
use RS-232 COM mode.
Failure to heed this
warning can result in
damage to PC,
instrument or both.
RS-232 can be used for point-to-point communication with the R1104
and to configure settings on a CEMS ( R1100 ) unit. To connect to the
instrument using RS-232 topology, follow these steps:
1. Remove power from the instrument.
2. Connect the RJ45 end of a USB-to-RS-232 adapter cable to the
Data Port on the instrument.
3. Attach the USB end to any available USB Port on the computer.
The R1100/1104 RJ45 connector is multi-standard and provides both
RS-232 and RS-485 connectivity. To be clear, the ’RS’ nomenclature
(Recommended Standard) is a wiring standard and has nothing to do
with the programming steps required to get a device to respond.

Simple Serial communications as used by HyperTerminal or another
serial communications program must supply commands to the
instrument that the instrument understands. These commands can
change the operating parameters for the CEMS
R1100 .
The Modbus R1104 uses the Modbus ASCII communication protocol
for instructions. The LMS 485 Gateway provides communication to an
instrument on an RS-485 LAN while connected to an Ethernet LAN for
PC communication. It requires a PC or server running a Modbus
communication package, such as
LMS Express , Express RT or LMS
Professional , connected to the Ethernet LAN. A PC can usually
