6. Programming

6.1 Using SCWIN

SCWIN is the easiest and typically the preferred method for programming the

datalogger. SCWIN generates a wiring diagram that shows how to connect the

CS450/SC455 to your Campbell Scientific datalogger.

The sections that immediately follow are for CRBasic and Edlog.

NOTE

Keyboard/Display users. SCWIN users can jump ahead to the Maintenance

section.

6.2 Using CRBasic or Edlog

6.2.1 CRBasic Programming

Dataloggers that use CRBasic include our CR200-series, CR800, CR850,

CR1000, CR3000, and CR5000. These dataloggers use the SDI12Recorder to

read the CS450/CS455. A multiplier of 1.0 and an offset of 0.0 yield water

level in psig and temperature in degrees C.

The SDI12Recorder instruction has the following form:

SDI12Recorder(Destination, Output String, Multiplier, Offset)

1 2 ... 17 18 19 20 21 22 23 24 25 26 27 ... 33 34
