6.1

General Purpose Input/Output (GPIO)

The camera has an 8-pin GPIO connector on the back of the case; refer to the diagram below for wire color-coding.
The connector is a Hirose HR25 8 pin connector with part number: HR25-7TR-8SA. The male connector is part
number: HR25-7TP-8P(72).
Diagram
Power can be provided through the GPIO interface. The camera selects whichever power source is supplying a
higher voltage.
