Communication Ports
The RS-485 port is a dual purpose connection. It is a hybrid of the
MODBUS over Serial standard incorporating both short distance single
instrument RS-232 and long distance multi-point RS-485.
The RS-232 protocol is provided for quick simple cable connections
from a single unit to a standard PC COM port.
The RS-485 MODBUS protocol is provided for industrial applications
with multiple devices on the same bus. The RS-485 IN connector
allows for easy connections using standard CAT 5 cable commonly
used for office LANs. Attaching the instrument to an RS485 network
requires special attention to topology (wiring scheme of network)
before and after the design phase to make sure the REMOTE and other
instruments perform as expected.
