RS-485 communications are intended to communicate with a PC using ModBus RTU or
Standard Bus. The maximum number of chambers connected to a single PC is limited
to 247 controllers (Modbus) or 16 controllers (Standard Bus). Chambers 6011, 6012,
and 6013 have one controller each. 6010 and 6015chambers have two controllers
each.
Connect shielded wires to the RS-485 Communications terminal blocks.
Communications wires should be shielded and routed away from power wires.
Maximum distance of total wire is 2000 feet. When connecting multiple chambers, route
wires in a daisy chain fashion. A termination resistor of 120 ohms may be placed across
RS-485(-) and RS-485(+) of the last chamber in the daisy chain.
For PC’s having an RS-232 serial port (9-pin D-Sub) connection, an RS-485 to RS-232
converter may be used. Recommended sources are B&B Electronics (P/N 4850I9TB)
and CMC-Connecticut Micro Computer (ADA485L).
SFTW301 software is available from CARON to load onto a PC to monitor and record
data. This data storage is not 21CFR Part 11 compliant.
