5.8 I/O in the Camera Link Interface
5.8.1 Inputs
The camera is also equipped with three input lines built into the Camera Link interface. These lines 
are designated as CC1, CC2, and CC3 as specified in the Camera Link standard. Typically, input 
signals are applied to these lines by the frame grabber board attached to the camera. The frame 
grabber board can typically be configured to supply different types of signals to these inputs as 
required by the camera user. 
On the camera side, you can select these inputs to act as the source signal for the following camera 
functions:
 the acquisition start trigger
 the frame start trigger
For more information about using CC1, CC2, and CC3 on the specific type of frame grabber 
installed in your system, refer to the documentation for you frame grabber board. 
You can also obtain some general information about how these lines are implemented in the 
Camera Link interface from the Basler document named Ace Camera Link Information for Frame 
Grabber Designers (AW000990xx000). You can obtain the document from the Downloads section 
of the Basler website:

For more information about using CC1, CC2, and CC3 as the source signal for a camera function, 
see Section 6.1 on page 49.
5.8.2 Outputs
As specified in the Camera Link standard, a "CL Spare" data bit is included in the Camera Link 
interface. On ace Camera Link cameras, the CL Spare data bit can be used as a camera output line. 
You can select any one of the camera’s standard output signals to act as the source signal for the 
for the CL Spare line. The camera has four standard output signals available: 
 Acquisition Trigger Wait
 Frame Trigger Wait
 Exposure Active
 Frame Cycle
You can also designate the line as "user settable". If an output line is designated as user settable, 
you can use the camera’s API to set the state of the line as desired.
