GPI Control
General Purpose Interface (GPI) is a high/low voltage
signalling protocol that allows the switcher to send simple
commands to an external device, or receive commands
from a device. Each pin on the GPI is set as either high
(+5 Volts), or low (0 Volts), and it is the switching
between high and low that sends commands to the
external device, or to the switcher.
The switcher has both xed and congurable GPIs. The
10 xed GPI inputs and 10 xed GPI outputs are located
on the Frame CPU board. The 24 GPIs on each Reference
with Tally board can be congured as either an input, or
an output.
GPI Trigger Types
There are four trigger types supported by the switcher.
These can be either output triggers, or input triggers.

To Set the Direction of a GPI
Note: Only the GPIs on the Reference with Tally board support
setting a direction.
1. Press HOME > Setup > Installation > GPI
Input/Output > GPI Direction.
2. Use the GPI knob to select the GPI that you want
to set as an input or output.
3. Use the Direction knob to set the GPI as an Input
or an Output.
4. Press HOME > Confirm.
GPI Inputs
GPI inputs can be used to trigger a number of events on
the switcher from a GPI I/O device. An example of a
commonly used GPI input is the small, hand-held, trigger
a weather forecaster uses to advance though the different
backgrounds in the weather forecast.
When the switcher receives a trigger on the selected GPI
input, it runs the events that have been assigned to the
GPI input.
To Set Up a GPI Input
1. Press HOME > Setup > Installation > GPI
Input/Output > Inputs.
2. Use the GPI Input knob to select the GPI input that
you want to assign an event to.
3. Use the Function knob to select the type of event
that you want to assign to the selected GPI input.
Tip: The Cut and Auto event start a transition in the
transition area of the selected ME. Use a memory recall to
set up the transition area with the keys and/or background
that you want transitioned before the GPI input occurs.
• Off — no event is triggered.
• Auto — an auto transition is performed on the
selected ME or Fade To Black module. Use the
Area knob to select where you want to transition
performed.
• Cut — a cut transition is performed on the
selected ME or Fade To Black module. Use the
