Control of GPI Devices
You can control GPI devices from the control panel of this system, or through
the GPI output port of a DCU.
GPI timeline
For a keyframe effect controlled from the center control panel, the GPI timeline
allows you to set an action (setting a trigger output from a particular GPI output
port) at a keyframe point on the GPI timeline. At any keyframe point, you can
make a maximum of eight GPI output port settings.
GPI timeline actions
The actions that can be used on the GPI timeline are as follows.
• Control panel GPI output port
• DCU GPI output port
For the GPI output settings (keyframe editing), use the Device menu.
The data set in the Device menu are saved in a keyframe effect register. When
you recall this register and start execution of the keyframe effect, and advance
the effect to the keyframe point for which the GPI output is set, a trigger pulse
is output to the external device from the specified GPI output port.
GPI Timeline Creation and Editing
This section describes how to set GPI output ports to be registered at a
keyframe point, and how to carry out creation and editing of the GPI timeline.
For details of keyframe creation and editing operations, see “Creating and
Editing Keyframes” (page 648).
GPI output port settings
Set the GPI output port number of the control panel or DCU which outputs GPI
pulses at a keyframe point on the GPI timeline.
Use the following procedure. (Use the same procedure to subsequently change
the settings.)
