connectors.

U and C 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. However, multiple SDI-12 sensors can connect to the same
data logger control or U terminal. Each must have a unique SDI-12 address. Valid addresses are 0
through 9, a through z, and A through Z.
For the CR6 and CR1000X data loggers, triggering conflicts may occur when a companion
terminal is used for a triggering instruction such as
TimerInput()
,
PulseCount()
, or
WaitDigTrig()
. For example, if the RainVUE-series is connected to C3 on a CR1000X, C4
cannot be used in the
TimerInput()
,
PulseCount()
, or
WaitDigTrig()
instructions.
7.4 Data logger programming
Short Cut
is the best source for up-to-date programming code for Campbell Scientific data
loggers. 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.
NOTE:
Short Cut
cannot edit programs after they are imported and edited in
CRBasic Editor
.
A
Short Cut
tutorial is available in
(p. 2). If you wish to import
Short Cut
code into
CRBasic Editor
to create or add to a customized program, follow the procedure in
Short Cut code into CRBasic Editor
(p. 26). Programming basics for CRBasic data loggers are
