5.9.3 Selecting the Input as the Source Signal for a
Camera Function
When a GPIO line is set to operate as an input, you can select the input to act as the source signal
for the following camera functions:

the acquisition start trigger

the frame start trigger
Note that when the input has been selected as the source signal for a camera function, you must
apply an electrical signal to the input that is appropriately timed for the function.
For more information about using the input line as the source signal for a camera function, see a
following version of the manual.
5.9.4 Operation as an Output
This section describes the electrical operation of the GPIO line when the line has been set to
operate as an output.
5.9.4.1 Voltage Requirements
NOTICE
Voltage outside of the specified range can cause damage.
You must supply power within the specified voltage range.
To ensure that the specified voltage levels for signals transmitted out of the
camera will be reached even under less than favorable conditions (eg. for long
cable lengths, harsh EMI environment, etc.), we recommend to generally use an
external pull up resistor or to connect a "high side load".
