GPIO Wiring
General Purpose Input/Outputs (GPIO)
are binary I/O ports used on Savant
controllers to trigger an action within
the system. Events can control a device,
such as turning on an amplifier (output)
or detecting a state change for a device
(input) to perform a workflow. Pin 2 is
used for input or output depending on
configuration.
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.
Stereo Wiring
The Balanced Audio Output
wiring uses included 5-pin
connectors. Each connector
has connections for Left and
Right channels and a ground.
NOTE: The Right and Left
channels share a ground
connection terminal.
Making Connections
1. Remove Power if power is
applied.
2. Pull to remove the terminal block
from the rear of the controller.
3. With a small flat bladed
screwdriver, turn the screws
on the top of the connector
counterclockwise until the
silver crimps in the front of the
connector opens enough to slide
the wire(s) into the square slots.
4. Strip back the insulation on each
of the wires ¼ inch. Insert the stripped wires into their proper ports.
Do not allow more than 1/8 inch of bare wire exposed.
5. Turn the screws clockwise until the screw tightens around the wire.
Tug on the wire a bit to verify the wires are installed securely.
6. Continue until all wires are installed.
7. Repeat steps 3 - 5 for any additional IR devices.
8. Plug terminal block back into the rear of the controller.
9. Reapply power.
NOTE: While not shown this
diagram, GPIO 2 follows the
same wiring as GPIO 1.

Resets the network settings of the device.
Hold Reset Button for 5 seconds while powered
on to clear network settings. Status LED will
rapidly blink red when reset is complete.

GPIO Input: When configured as an input the
processor will look for a low (<0.8V DC) or a
high (>2.4V DC) state.
Minimum 0V DC / Maximum 12V DC.
GPIO Output: When configured as an output, the
port provides a binary output of 0-12V
DC 150mA max.
