7.2 Mounting
Orient and secure the CS230/CS231 in the measurement medium. Keep
materials removed during installation and use that material as backfill.
While installing the CS230/CS231, the depth must be referenced between the
surface of the medium and the first measurement point in the assembly (shown
in FIGURE 7-1 , Internal Sensor Position #4). If the rigid assembly is not
placed at the correct depth, all measurement depths will be out of place.
Install the external probes horizontally in the measurement medium. This helps
ensure that the most representative measurement is taken at the given depth,
and will not interfere with other nearby measurements.
Orient the signal and power cable of the CS230/CS231 towards the data logger
to avoid loops or strain on the cable. Also use a suitable trench or conduit to
protect the signal and power cable from damage.
7.3 Wiring
TABLE 7-1 provides the connections for the CS230/CS231 and Campbell
Scientific data loggers. Refer to Appendix D , SGB3 Electrical Surge Protector
(p. D-1)
, if the CS230 serial number is less than 1162.

1 U terminals are automatically configured by the measurement instruction.
If multiple SDI-12 sensors are connected to a data logger, Campbell Scientific
recommends using separate terminals when possible. For the CR6 and
CR1000X, triggering conflicts may occur when a companion terminal is used
for a triggering instruction such as TimerInput() , PulseCount() , or
WaitDigTrig() . For example, if the CS230/CS231 is connected to C3 on a
CR1000X, C4 cannot be used in the TimerInput() , PulseCount() , or
WaitDigTrig() instructions.
7.4 Programming
Short Cut
is the best source for up-to-date data logger programming code. If
your data acquisition requirements are simple, you can probably create and
maintain a data logger program exclusively with Short Cut . If your data
acquisition needs are more complex, the files that Short Cut creates are a great
source for programming code to start a new program or add to an existing
custom program.
Short Cut cannot edit programs after they are imported and edited in CRBasic
Editor .
