5.3 A150/CWS900
The A150 desiccated case allows the CS450/CS455 to be connected to the
CWS900 wireless sensor and then used in a wireless network. FIGURE 5-1
shows the CS450 wired to the A150’s terminal block. The 26972 cable is
included with the A150.

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.
