3.3.5. GPIO-In
The GPIO-In connector provides four (4) general-purpose inputs. Four (4) independent detector
circuits are used, driven by an on-board +5V source. Each detector’s input is connected to its
corresponding pin, and paired with a COM reference pin per input. When switched on by an
external connection, each input will source about 12mA to COM.
Connect external equipment to this connector. Connect a pin to its corresponding COM to turn the
input on.
