Communications
RS-485 communications are intended to communicate with a PC using ModBus RTU or
Standard Bus. The maximum number of incubators connected to a single PC is limited
to 247 controllers (Modbus) or 16 controllers (Standard Bus). Each incubator has 3
controllers.
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 incubators, 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 incubator 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.
Installing Drain Water Pump (PUMP301)
In applications where a floor drain is not available and a CARON water recycling system
is not being used, a drain pump can be purchased to pump any excess condensate from
the incubator to a local sink or drain. The pump is located near the middle of the back of
the incubator. Connect the supplied tubing from the pump to the sink / drain. The
tubing may be run vertically into a ceiling but should not exceed 15 feet height.
Installing Side Mounted Recorders (RCDR305 & RCDR306)
The recorder will arrive packaged inside the incubator. Carefully remove the recorder
from its packaging. Mount the recorder by using the pre-installed recorder bracket.
There are three factory drilled holes located on the right side of incubator as you face
the front of incubator. Using the factory supplied screws, screw the recorder to the side
of the incubator.
There are two cables that come out of the recorder. One is to power the recorder; the
other is the temperature and/or humidity signals coming from the incubator. With power
to the equipment turned off, plug the two connectors into their mating connector at the
top of the incubator. Turn power to the incubator back on.
