I/O Control
This chapter shows the structure of the physical input and physical output lines. It describes the
signal path and how to configure it.
The I/O control block contains a signal input path and a signal output path.
7.1 Input Signal Path
The camera has four physical signal input lines, which come from the input opto-isolator of the
camera hardware interface (see Section 13.6) and which are fed into the input signal path of
the camera. Fig. 7.1 shows the structure of the input signal path. The user can invert this signal
and its current status can be read by software.
