internal connectors’ description
The CS125 has three standard IP66 rated glands. The first gland is by default used
by the power/communications line. This comprises the +12V/24V for the main
electronics, and the serial communications wires. The CS125 is supplied with 5 m
cable already connected.
The second gland is used for the 24 V feeds for the hood heaters fitted with a 5 m
cable.
The third gland is spare.
If the power cable is incorrectly wired to the CS125 then
irrevocable damage can be done to the unit.
10 m is the longest length of the cable type supplied
recommended. In particular, additional RS485 communication
should be twisted pair. Please contact Campbell Scientific if
you wish to use a longer length of cable.
A configuration cable, part number 010817, is available from Campbell Scientific
that plugs directly into connector B, in place of the normal connector and cable.
The configuration cable is fitted with a 9-way D connector for use with a PC serial
port or USB to serial adaptor.
