3.7. GPIO Connections
The PAV-SIPA125SM, PAV-AOM8C, and PAV-AOMBAL8C have GPIO ports which share the same wiring. General Purpose Input/Output (GPIO) ports
are binary I/O ports used by Savant controllers to trigger actions within the system. GPIO actions may be configured to control a device, such
as turning on an amplifier (output), or detecting a device state change (input) to perform a triggered workflow. Pin 2 is used for input or output
depending on configuration.
NOTE:
While not shown this
diagram, GPIO 2 follows the
same wiring as GPIO 1.

GPIO Pull Down Resistor (PD) Usage
GPIO pins are configured as inputs and are pulled high to 12V while the host is booting up. To make the GPIO
signal low during a host reboot and/or a power cycle, attach the GPIO 1 pin to the PD pin. The PD pin is a 1K ohm
pull down resistor (to signal ground) which keeps the GPIO output below 0.8V during processor boot times.
HELPFUL INFO
: GPIO functionality for Savant Controllers is defined by the associated Profile used within RacePoint Blueprint. All further
programming (State Trigger configuration for example) must also be done within Blueprint. For further information on programming of
GPIO and relay ports, refer to the Relay and General Purpose Input/Output Profiles - Application Note, available on the Savant Customer
Community.
3.8. Relay Connections
The PAV-SIPA125SM features a relay port, used to control components via a normally open (NO) or normally closed (NC) relay.

HELPFUL INFO
: Relay functionality for Savant Controllers is defined by physical wiring (which should follow
specifications for the controlled component), as well as the associated Profile used within RacePoint
Blueprint. For further information on programming GPIO and/or relay ports, refer to the Relay and General
Purpose Input/Output Profiles - Application Note, available on the Savant Customer Community.
