7 I/O Control
7.2 Output Signal Path
The camera has three physical signal output line and two LEDs. The physical output lines are
connected to the output opto-isolator in the camera hardware interface (see Section 14.6). The
output lines, LED0 and LED1 have their own output signal path which is shown in Fig. 7.2. The
source can be selected and the selected signal can be invert before it is sent out of the camera.
Furthermore the current status of the output signal can read by software.

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.
