7.3. Digital Inputs
There are five types of Digital Inputs on the CrossFire GX1. Every port on the unit is capable of
being configured as a Digital Input (with the exception of Ports 2, 4, 6, 38, 40, 42) provided that the
ports are not already configured as something else.
For best results, the installation of the CrossFire GX1 should be such that the Digital Inputs are
matched with the type of signal source.
 For high-side drivers or open emitter, open source: hook up to Digital Inputs with pull-
down resistors
 For low-side drivers, open collector, open drain: hook up to Digital Inputs with pull-up
resistors
 For bipolar, totem-pole or “push-pull” signals, use either of the above types, or floating
inputs
