FIGURE. Switch Closure Pulse Sensor p. 42 is a generalized schematic showing connection of a pulse sensor to the CR200(X). The CR200(X) features two dedicated pulse input channels, P_SW and P_LL, and two digital I/O channels, C1and C2, for measuring pulse output sensors. Activated by the PulseCount () instruction, dedicated 16-bit counters on P_SW, P_LL, C1 and C2 are used to accumulate all counts over the user specified scan interval. -
Page 53: Pulse Input Channels
Section 4. Sensor Support Note: The PulseCount () instruction should not be used in a conditional statement or subroutine. To ensure all pulses are detected, it must be executed each scan. Execution of PulseCount () within a scan involves determining the accumulated counts in each dedicated 16-bit counter since execution of the last PulseCount (). -

Page 65: Section 7. Grounding
Section 7. Grounding Grounding the CR200(X) and its peripheral devices and sensors is critical in all applications. Proper grounding will ensure the maximum ESD (electrostatic discharge) protection and higher measurement accuracy. ESD Protection ESD (electrostatic discharge) can originate from several sources, the most common, and most destructive, being primary and secondary lightning strikes. -
Page 66: Lightning Protection
Campbell Scientific has for many years employed a simple and inexpensive design that protects most systems in most circumstances. It is, however, not infallible. Note Lightning strikes may damage or destroy the CR200(X) and associated sensors and power supplies. In addition to protections discussed in ESD Protection (p. -

"Flag" works best because datalogger support software automatically adds variables call "Flag" to the Ports and Flags window. Because the CR200(X) does not support the Boolean data type, the IIF function may be used to distinguish between zero and non-zero values, effectively creating a Boolean value. -

Floating point arithmetic is common in many electronic computational systems, but it has pitfalls high-level programmers should be aware of.

AND / OR operators are the same for logical statements and binary bitwise comparisons. In the binary number system internal to the CR200(X), "-1" is expressed with all bits equal to 1 (11111111). "0" has all bits equal to 0 (00000000). -

If a sensor cannot perform continuous measurements, then it responds to aRv! with the sensor address. 11.4.2 SDI-12 Communications The CR200(X) supports SDI-12 communication through two modes – transparent mode and programmed mode. • Transparent mode facilitates sensor set-up and troubleshooting. It allows commands to be manually issued and the full sensor response viewed. - Page 127 For example, when the SDI12Recorder() instruction is programmed with the M! command (note that SDI-12 address is a separate parameter), the CR200(X) issues the aM! AND aD0! commands with proper elapsed time between the two. The CR200(X) automatically issues retries as well as other services designed to make the SDI- 12 measurement work as trouble free as possible.
