7 Input/Output Control

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.
