• When
Level
is assigned, the GPI output port’s line is held at the selected state (low
or high) until triggered, whereupon the line switches to the opposite state — and
holds there.
• When
Edge
is assigned, the GPI output port’s line is held at the selected state (low
or high) until triggered, whereupon the line switches to the opposite state
momentarily — and returns immediately to the original state.
• When
Low
is assigned, the GPI output port’s line is normally high. When the port
is triggered, the line goes low (to ground).
• When
High
is assigned, the GPI output port’s line is normally low. When the port is
triggered, the line goes high (released from ground).
Refer to your destination device’s documentation for details on the specific type of GPI
pulse that the device needs to receive.
This completes the procedure to set up your standard GPI output ports.
Tally on GPIs
Use the Tally on GPIs function to specify for each tally if it should be forced on by one of the GPI
inputs.
Tally on GPI Setup Menu
The top knob selects a tally number, while the middle knob specifies which GPI input (or NONE )
should force the tally on. Multiple tallies can be forced on by one GPI input. This forcing is
independent of the tallies being used to indicate, for example, which crosspoints are active. It is not
possible to tell from the tally side if it is on because of a crosspoint being used or because of the GPI
forcing.
GPI Information
Use the View GPI I/O Menu to display all the information about the GPI inputs and outputs in a
concise format.
