Control and video data signals
The inputs and outputs of the camera can be configured by software. The dif-
ferent modes are described below.
Inputs
The optocoupler inverts all input signals. Inversion of the signal is controlled
via the IO_INP_CTRL1..2 register (see Table 23: Advanced register: Input
control on page 76).
Triggers
All inputs configured as triggers are linked by AND. If several inputs are being
used as triggers, a high signal must be present on all inputs in order to gen-
erate a trigger signal. Each signal can be inverted. The camera must be set
to external triggering to trigger image capture by the trigger signal.
