7 I/O Control
7.2 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. 7.2. 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.

Figure 7.2: Output Signal Path
Following signals are available and can be selected for the output:
• Input Line
• Counter Active Status
• Timer Active Status
• User Output
• Acquisition Trigger Wait Status
• Acquisition Active Status
• Frame Trigger Wait Status
• Frame Active Status
• Exposure Active Status
• Frame Valid Status
• Line Valid Status
• Heartbeat
• Serial Communication
• Constant 0 Value
• Constant 1 Value
If the source heartbeat is selected, the led shows a pulsating behaviour, when the camera is
idle (no image capturing is active). It means, the intensity starts from dark and goes slowly to
bright and slowly to dark again. Every time, when the camera is acquiring and sending images,
the LED changes to a blinking characteristic.
If the source serial communication is selected, the led flashes every time when the host
communicates with the camera, due to changing or reading of camera parameters.
