The following signals are designated:
Signal
SerTFG
LVDS pair for serial communications to the frame grabber
SerTC
LVDS pair for serial communications to the camera
The serial interface must apply the following regulations:
▪
one start bit,
▪
one stop bit,
▪
no parity and
▪
no handshaking.

9.2.2. Camera Control

According to the CameraLink
purpose camera control. They are defined as frame grabber outputs and camera inputs. 
The definition of these signals is left to the camera manufacturer.
Signal
Camera Control 1 (CC1) FrameGrabberLine0
Camera Control 2 (CC2) FrameGrabberLine1
Camera Control 3 (CC3) FrameGrabberLine2
Camera Control 4 (CC4) FrameGrabberLine3

9.2.3. Video Data

The  standard  designates  four  signals  (as  well  as  the  signal  state)  for  the  validation  of 
transmitted image data:
Signal
FVAL
Frame Valid is defined high for valid lines.
LVAL
Line Valid is defined high for valid pixels.
DVAL
Data Valid is defined high for valid data.
Spare
Has been defined for future use.

9.3. Chip and Port Assignment

As previously stated CameraLink
Since the data processing of one Channel Link
may be required for an efficient data transfer. Depending on the configuration, a camera 
may be equipped with up to three chips.
The standard designates a port as an 8-bit word. The CameraLink
eight port (A-H).
