6. Connections and Wiring

The GPIO and relay connections are made using a 6-pin screw down plug-in connector supplied with the controller and power is supplied using the included

power supply. Use the information below when making control and power connections.

6.1. GPIO and Relay

General Purpose Inputs/Outputs (GPIO) are binary I/O ports used on Savant controllers to trigger an action within the system. Events can be to control a

device such as turning on an amplifier (output) or detecting a state change for a device (input) to perform a workflow. The left 3 pins of the supplied

connector are used for the GPIO connections.

Relays are used when a contact closure (normally open/normally closed) is needed to activate a device such as raising or lowering shades, opening or

closing a gate, or sending control signals to an HVAC system are a few examples. The right 3 pins of the supplied connector are used for the relay

connections.

6.2. 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 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 earth ground) which keeps the GPIO output below 0.8V

during the processor boot times.

To connect wires into terminal block connector:

Remove power if power is applied.

Pull to remove the connector from the rear of the controller.

With a small flat bladed screwdriver, turn the screws on the top of connector

counterclockwise until the silver crimps in the front open enough to slide the wire into the

square slot.

Strip the ends of each wire to

wires into the proper slots.
