3.3.5. GPIO-In
The GPIO-In connector provides 4 general-purpose inputs. 4 independent detector circuits are used,
driven by an on-board +5 V 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 12 mA to COM.
Connect external equipment to this connector. Connect a pin to its corresponding COM to turn the
input on.
