Digital inputs
Digital inputs are used to process frequency signals (e.g. engine speed sensors, turbocharger
speed sensors, Flex Fuel sensors) and beacons, as well as switches.
It is possible to read signals from inductive sensors (VR sensors), Hall effect sensors or optical
sensors. The digital inputs have built-in switchable 2k2 pull-up resistors (pull-up to +5V), which
may be used for Hall sensors or switches shorted to ground.

Connection example for crankshaft position
sensor (Hall and VR sensor).
If an VR sensor is used, it is recommended to
use shielded wires.
