I/O Control
This chapter shows the structure of the physical input and physical output line. 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.
6.1 Input Signal Path
The camera has one physical signal input line, which comes from the input opto-isolator of the
camera hardware interface (see Section 13.6) and which is fed into the input signal path of the
camera. Fig. 6.1 shows the structure of the input signal path. The user can invert this signal
and its current status can be read by software.

The output of the signal input path is distributed to following camera function:
• Acquisition Start Trigger
• Acquisition End Trigger
• Frame Start Trigger
• Frame Burst Start Trigger
• Frame Burst End Trigger
• Exposure Start Trigger
• Exposure End Trigger
• Counter Trigger
• Counter Event
• Counter Reset
• Timer Trigger
• Line Out
• LED S0, S1 or S2
6.2 Output Signal Path
The camera has one physical signal output line and three LEDs (S0, S1 & S2), which can be
configured according to the need of the application. The physical output line is connected to
the output opto-isolator in the camera hardware interface (see Section 13.6). The output line,
LED0, LED1 and LED2 have its own output signal path which is shown in Fig. 6.2. The source
can be selected and the selected signal can be inverted before it is sent out of the camera.
Furthermore the current status of the output signal can read by software.
Following signals are available and can be selected for the output:
