General Purpose Input Output (GPIO)

This test connects a special adapter to the device's external GPIO interface and performs a series of continuity tests to ensure that all of the communications pins are functional.

Pass/Fail Criteria

  • All I/O pins must be able to input and output signals as per the device specification.
Small, Standard, and Large Case Models
Color Pin Line Function Description
Black 1 N/A GND DC camera power ground
White 2 N/A POWER DC camera power
Red 3 Line 1 GPIO_OPT_OUT1 Opto-isolated output (GPO1)
Green 4 Line 4 GPIO_OPT_OUT2 Opto-isolated output (GPO2)
Orange 5 Line 0 GPIO_OPT_IN1 Opto-isolated input (GPI1)
Blue 6 Line 3 GPIO_OPT_IN2 Opto-isolated input (GPI2)
White with black stripes 7 Line 2 GPIO_TTL_IO3 TTL input/output 3*
Red with black stripes 8 Line 5 GPIO_TTL_IO4 TTL input/output 4*
Green with black stripes 9 N/A GND DC camera power ground
Orange with black stripes 10 N/A POWER DC camera power
Blue with black stripes 11 Line 6 3.3 V OUTPUT +3.3 V output, current 120 mA (nominal) - firmware enabled
Black with white stripes 12 N/A OPTO_GND Ground for opto-isolated I/O, not connected to camera ground
*When configured as output line format is open drain, not TTL. Users should attach their own external pull-up resistor.
