• GPI Trigger Coding Selects GPI triggering as follows:
• Disabled: GPI conditions on both GPI ports are ignored; no preset
is invoked as a result of GPI status. Use this setting as a master
disable of GPI functions.
• Edge and Binary: See the description and examples below.
Note: Make certain GPI Trigger Coding is set to Disabled if GPI is not to
be used. Selecting Binary triggering without controlled GPI
inputs will result in inadvertently invoking a preset.

Edge GPI coding triggers on transitional state changes occurring
on individual GPI inputs for the four states on the GUI (shown to
the right).
In this example, when GPI 2 “closes” (edge trigger going
from HI to LO), Preset 7 is invoked. Preset 7 would be
defined to invoke the settings desired for this GPI action.
When GPI 2 “opens” (edge trigger going from LO to HI),
Preset 8 is invoked. Preset 8 could be defined to invoke
normal settings to revert to the pre-GPI condition. The state
shown in bold is the currently active state.
Binary GPI coding triggers on conditions that consider state combinations on both GPI 1 and GPI 2 for the four state combinations
on the GUI (shown to the right). This mode is useful where both GPIs must be considered before invoking an action.
In this example, both GPIs are to be considered:
- “AES local insertion” on GPI 1 preempts network embedded audio by invoking Preset 2.
- “EAS insertion” on GPI 2 preempts both network embedded audio and AES local insertion by invoking Preset 3.

Invoke Preset 7 Invoke Preset 8
Setting both of these
drop-downs to Preset 3
sets rule for if GPI 2 is
closed (LO), Preset 3
(“EAS insertion” in this
example) is invoked
regardless of open/
close on GPI 1.
GPI 1 (“AES local insertion”)
GPI 2 ( “EAS insertion”)
Invoke Preset 2
(“AES local
insertion”)
Invoke Preset 1
(“norm”)
Invoke Preset 3
(“EAS insertion”)

See “Audio Routing with GPI
Control Example” (p. 3-59) for a
example showing the audio
routing presets described here.
If GPI 1 is closed (LO), and
GPI 2 is open, Preset 2
(“AES local insertion” in this
example) is invoked.
In this setup, when both
GPI 1 and GPI 2 are open
(HI), Preset 1 (“norm”, or go
back to network embedded)
is invoked. The state shown
in bold is the currently active
state.
