3.4.5 General Purpose Inputs & Outputs (GPIO)
The general purpose I/O port can be used for ground-activated interaction with connected
devices such as OEM steering wheel buttons for certain compatible vehicles.
Inputs:
The Module has four programmable ground-activated inputs. OEM Steering wheel
buttons or similar devices may be connected to these inputs.
GROUND (0 volts) is recognized to be an ACTIVATED input.
FLOATING is recognized to be a NON-ACTIVATED input.
NOTE:
GPIO pins should never be connected to BATT+ voltage. The pins are not compatible with
the vehicle’s alternator and voltage system. If needed, nonactivated inputs can be pulled
weakly to 5-12V regulated DC.
Outputs:
The Module has four programmable ground-activated outputs. Low current controlled
devices may be connected to these outputs.
GROUND (0 volts) is supplied when the output is ACTIVATED.
FLOAT/OPEN is supplied when the output is NON-ACTIVATED.
