The GPI Interface is used to trigger function-key sequences (of
up to 500 keystrokes each) via external switch closures. Func-
tion Key setup and operation is provided in Section 12 of this
manual.
The normally open single-pole GPI switches shown in the dia-
grams are not included with the system. Any type of momentary
switching device may be used, but switch contact bounce time
must be 20 ms or less.
This section is divided into separate parts due to differences in
the iNFiNiT! Family hardware configuration.
