3.5. GPIO signal specifications
The GPIO signals specifications are shown below.
GPIO_IN specification (Trigger in)
The voltage applicable to GPIO_IN should be + 5V to + 12 VDC.
When using with a power supply voltage higher than that, combine an appropriate resistor.
The circuit diagram is as follows.
GPIO_OUT specification (ExposureActive or UserOutput)
GPIO_OUT can pass a current of ~25mA to GND_GPIO_OUT at the time of output.
The circuit diagram is as follows.
