7. Installation

If you are programming your data logger with

Short Cut

, skip

Wiring to the data logger

(p. 6) and

Programming

(p. 7).

Short Cut

does this work for you. See

QuickStart

(p. 1) for a tutorial.

7.1 Wiring to the data logger

Connect the SN500SS to the data logger in the order shown in

Table 7-1

(p. 7).
