GPIO Electrical Characteristics

Both the opto-isolated input and output have over current protection.

The output is open collector and thus requires a pull-up resistor to operate. The rise time and bias current will be determined by the resistor value chosen. If the camera is generating an output signal that approaches the rise time plus the fall time of the opto-isolated circuit, care must be taken to optimize the pull-up resistor chosen to minimize the rise time while still remaining within the current limits of the output circuit.

The opto-isolated specifications listed below are applicable when power to the camera is provided through the interface and not through the GPIO.

Warning! To avoid damage, connect the OPTO_GND pin first before applying voltage to the GPIO line.
Warning! Prolonged use of the camera outside of the Operating Range described below may lead to unexpected behavior and should be avoided.
