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.

---|---|---|---|---|
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. |
