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/CS455 to your Campbell Scientific datalogger.

The sections that immediately follow are for CRBasic and Edlog.
