3.1–4 GPI 1–4 OUT
The setting of this parameter determines whether certain FS3 events will
generate a GPI trigger output at GPI outputs 1, 2, 3, or 4.
No Action
(default)
Alarm
No Video
No Ref
Does not trigger a GPI output regardless of event.
Generates a GPI out trigger if an internal alarm condition occurs.
Generates a GPI out trigger if no video is detected at the input.
Generates a GPI out trigger if no video is detected at the Ref input.
Interaction of Presets and GPIs
If you use a GPI input trigger to recall a preset, the recall changes the GPI IN
Response setting to whatever GPI IN Response setting the preset contains. As the
following examples explain, this feature offers both the power of serial recalls and
the possibility of triggering a recall that changes GPI IN Response to something
unintended.
Example of a Serial Recall
The advantage of using GPI IN Response with presets is that you can trigger a
series or even a looping series of preset recalls. For example, suppose GPI IN 1
Response in Preset 1 is set to Preset 2, and GPI IN Response in Preset 2 is set to
Preset 1. Triggering the GPI will toggle between the two presets.
Example of an Unintended Recall
Suppose you trigger GPI IN 1 while the current GPI IN 1 Response parameter is set
to Preset 1. This recalls Preset 1 as expected. However, suppose Preset 1 contains
a stored GPI IN 1 Response setting of No Action. If you trigger GPI IN 1 later,
expecting to recall Preset 1 again, the FS3 instead performs No Action. To prevent
unexpected changes in the GPI IN Response parameters, set these parameters as
desired before storing presets; in the example, set GPI IN 1 to Preset 1 before you
store Preset 1.
