SECTION 22.9 GPI CONTROLLERS
GPI, or General Purpose Interface, is long serving analog control signal system based
on simple contact closure. GPI inputs and outputs are very common on professional
production equipment.
The macro system in NewTek live production devices can take advantage of
intermediary devices, such as the eBOX™ network/GPI hardware interface from
JLCooper Electronics, to support both GPI signal input and output.
