Appendix B. Controlling power
to the RV50(X)
The RV50 uses considerably more power than the data logger. Therefore, it may be necessary to
use the data logger to control power to the RV50. The following program examples show how to
control power to the RV50 using the switched 12V (SW12V) terminal on the data logger.
This example shows how to control power to the RV50 by using the CRBasic TimeIsBetween()
instruction to turn on SW12 for 15 minutes every 60 minutes between 9:00 a.m. and 5:00 p.m.
NOTE:
TimeIsBetween() requires operating system version 28.00 or greater in the CR1000,
CR3000, or CR800. It is supported in all CR1000X, CR6, and CR300 operating systems.
