2. 1 –4 GPI IN 1–4 Response
The setting of this parameter determines what happens when a GPI trigger is
received at the FS-HDR's GPI Inputs (1–4). A GPI Trigger is defined as a TTL low
voltage level (0 to 0.8V with respect to its isolated ground pin). The GPI interface
pinout and specifications are discussed in
sources selected by GPI trigger remain selected until the trigger is released.
Caution! GPI Inputs can be used to trigger Presets. When you recall a Preset
Configuration, the recalled preset immediately replaces the system's existing
configuration. All previous settings are lost unless you have previously stored
them in another preset configuration or an exported file.
In Four Channel Mode, each FS-HDR Video Processor can be programmed to
perform an action on each of the four GPI Inputs. This means the same GPI input
trigger could cause different actions on each channel. In Single Channel Mode,
each GPI input can only trigger one action on that Video Processor.
Caution! In Four Channel Mode, each Preset saves all the settings for all four
channels. Storing and recalling a Preset will affect all the settings for all four
channels in that mode. Care must be taken to establish a policy for the use of
FS-HDR Presets, especially if the FS-HDR is operated in Four Channel mode and
the different channels have different users.

In Single Channel Mode Vid appears on the front panel, because only one Video
Processor is available.
