EXAMPLE CIRCUIT
The circuit below shows an example applicaion which includes a base-unit that has one PID module and
one logic module fitted.
It is strongly recommended that the power supply zero volts and all logic module zero volts are
common to prevent ground loops.

Configuring and Networking CALogix
CALogix is configured using Windows-based CALogix-sw software. Before using CALogix–sw,
connect CALogix to a PC as shown below:
CALOGIX NETWORK
CALogix uses RS485 full duplex serial communications link which is the standard most commonly
used for industrial applications due to high noise immunity and multi-drop capability. It enables a PC to
communicate with up to 31 CALogix base-units over distances up to 1200 metres, and requires the
addition of an RS485 interface card, or a separate RS232 / 485 converter connected to the RS232 port
of the PC. RS485 converters that derive power from the RS232 port must have all 9 pins (RS232)
connected for full operation of the converter.
RS485 cards and converters can differ greatly in their requirements and therefore the installation
instructions supplied with the interface should be read carefully.
2m CALogix-PC cable (part number - CAB RJ45 2M 01) and a RS232/485 converter (part number -
3C 25 000 K 3X) that fits directly on to the RS232 serial port on a PC are available from your nearest
CAL Controls distributor.
