WARNING: NEVER plug a power source (such as an AC adapter) into a GPI
jack. Damage to the device might occur which could void the warranty on
the device.

c) How to determine if a GPI-compatible external device utilizes a single or
double GPI trigger.
Create an effect with the device and play it back (typically by pressing a
"PLAY" key).
When you press "play", does the effect both appear on screen and then
disappear from the screen without pressing any other keys? If so, the device
utilizes a SINGLE trigger.
When you press "play", does the effect appear on screen, then remain on
screen until you press "play" (or some other key) again? If so, the device
utilizes a DOUBLE trigger.

b) What is the difference between a "single" and "double" GPI trigger?
Any device that has a "single" GPI trigger (eg. the Datavideo SE-300 Digital
Video Illustrator), utilizes just one electrical pulse to control the duration of
an effect (the single pulse signals both the "in" and "out" points of the effect).
Any device that has a "double" GPI trigger utilizes two electrical pulses to
control the duration of an effect (one to signal the effect's "in" point; the
other to signal the effect's "out" point). This concept is illustrated below:
NOTE: to connect the SE-200's GPI jack to the GPI jack on an external
device, use a standard 3.5 mm stereo cable (a cable with a 3.5 mm
stereo plug on both ends):
