Carrying out setup relating to GPI inputs (GPI INPUT menu)
You can use the GPI INPUT menu for the following settings relating to
switcher and DMK-7000 GPI inputs.
• Selecting the trigger polarity: Select the trigger polarity from the
following five kinds.
: Trigger on the rising edge of an input pulse.
: Trigger on the falling edge of an input pulse.
: Trigger when the input changes polarity.
NOP: No triggering by input pulse.
LEVEL: When the input level goes low, the specified mode switching
occurs. Unlike other types of trigger polarity, in this case you can
only select from the screen aspect ratio (4:3/16:9), the signal format
(D1/D2), the number of scan lines (525/625), and in the case of the
DMK-7000 the EMG input selection, as the operation controlled.
Changing the signal format or the number of scanning lines using a
GPI input resets the entire system.
• Selecting the trigger action: Select the action triggered by the GPI input.
When the trigger polarity is set to "LEVEL", you can only select
from the operations listed above under "Selecting the trigger
polarity".
When the trigger polarity is set to other than LEVEL, select the
required action from the following.
For the switcher:
• On each M/E bank: CUT, AUTO TRANS (auto transition), KEY 1
• For frame memories 1 and 2: FREEZE, CLEAR
• SS RECALL (recall snapshot), EFF RECALL (recall effect),
