GPIO and Relay Wiring
General Purpose Input/Outputs (GPIO) are binary I/O ports used on
Savant® controllers used to trigger an action within the system. Events
can be the control of 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 6-pin Screw Down Plug-in Connector are
used for GPIO connections.
Relays are used when a contact closure (normally open or normally
closed) is needed to activate a device. An action 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
6-pin Screw Down Plug-in Connector are used for Relay connections.
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.
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
connector counterclockwise until the silver crimps in the front of the
connector opens enough to slide the wires into the square slots.
4.
Insert one of the stripped wires from the devices being controlled
into its respective slot in the connector. Refer to the diagrams above.
5.
Turn the screw clockwise until the screw tightens around the wire.
Tug on the wire a bit to verify it is installed securely. Do not allow
more than 1/2 inch of stripped wire exit from the rear of the
connector.
6.
Repeat for each wire till all wires are installed.
7.
Plug terminal blocks back into rear of the controller.
8.
Reapply power.

harmful interference when the equipment is operated in a residential
environment. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications,
However there is no guarantee that interference will not occur in a
particular installation, If this equipment does cause harmful
interference to radio or television reception, which can be determined
by turning the equipment o
ff
and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
- Reorient or relocate the receiving circuit di
ff
erent from that to which
receiver is connected.
- Increase the separation between the equipment and the receiver.
- Consult the dealer or experienced radio/TV technician for help.
