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. NOTE
