U and C terminals are automatically configured by the measurement instruction.
For 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 this product is connected to C3 on a CR1000X, C4 cannot be used in the
TimerInput(), PulseCount(), or WaitDigTrig() instructions.
6.1.3 RS-232 wiring
The RS-232 output can be directly read by a CR6 or CR1000X data logger (Table 6-3 [p. 11]).

6.2 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.
