QUARTZ-ONYX
Hardware Manual
General
The GPIO terminal block on the QUARTZ-ONYX works with a 5-way connector from
Phoenix Contact, part number 1881354.
To connect wires to the connector, press in the orange-coloured
button to open the jaws of the clamp below the button. Insert
the wire and then stop pressing the button to close the jaws of
the clamp.
The connector has polarizing lugs on it which prevent not only
the connector from being plugged in incorrectly, but also prevent
the use of connectors smaller than 5-way from being used.
GND is ground (0 V) and is the reference for the digital inputs and outputs.
