The rear panel connector on a 26-pin D-SUB
provides:
•
6 GPI: 4 to recall user-configurable presets
and 2 for input selection.
•
6 GPO: output tallies for the selected user
preset and the input selection.
•

for audio metadata
GPI and GPO are both contact closure to ground,
except GPI 1 and GPI 5 which can also trig
events on contact release.
