Campbell CS211 Quick Deploy Manual

CS211
1. Introduction
The CS211 Smart Enclosure Sensor enables both remote and
onsite monitoring of internal enclosure conditions, such as
temperature, humidity, and door status (open or closed). It also
features a button that detects single and double presses to
execute user-defined functions, and an LED to indicate if the
enclosure desiccant needs to be replaced.
This manual provides information specific to using a CS211 with
CRBasic data loggers.
2. ShortCut
Short Cut is an easy way to program your data logger to
measure the sensor and assign data logger wiring terminals.
Short Cut is available as a download on
www.campbellsci.com/shortcut
It is also included in installations of LoggerNet, RTDAQ, and
PC400. For more information on using Short Cut, see the full
CS211 user manual www.campbellsci.com/cs211
3. Wiring
The CS211 comes with three 61 cm (24 in) long cables to
connect from the screw terminals of the CS211 to the data
logger. Contact Campbell Scientific if a longer set of cables is
required.
Table 3-1 provides connections to Campbell Scientific data
loggers. Connect the wires in the order shown in the table.

NOTE:
Campbell Scientific recommends connecting the CS211 to
a constant (non-switched) 12V terminal. Switching power
to the CS211 will reset some accumulative values stored in
volatile memory.
4. Reflective tape
The CS211 uses an optical sensor and the LED to detect if the
enclosure is open or closed. To enable this feature, install the
reflective tape inside the enclosure door, such that it is directly
in front of the sensor when the door is closed.
