Chapter 2 Using the Hardware

Using the GPIO Interface

Use the GPIO Cable to connect the RS700 to several external controls such as an LED indicator lamp, LCD or motion sensor.

GPIO Pin Assignment

Connect two relay output and digital input signals with the 10-pin GPIO cable. Con- nect external devices through the following:
