Some thinner CameraLink

cables have a predefined direction. In these cables

not all twisted pairs are separately shielded to meet the RS644 standard. These
pairs are used for the transmission of the RX/TX and for the CC1 to CC4 low
frequency control signals.

transmission

Figure 5.38: LFSR test pattern received at the frame grabber and histogram containing transmission errors

CameraLink

®

cables contain wire pairs, which are twisted in such a way that the

cable impedance matches with the LVDS driver and receiver impedance. Excess
stress on the cable results in transmission errors which causes distorted images.
Therefore, please do not stretch and bend a CameraLink cable.

In robots applications, the stress that is applied to the CameraLink

®

cable is especially high due

to the fast movement of the robot arm. For such applications, special drag chain capable cables
are available. Please contact the Photonfocus Support for consulting expertise. Appropriate
CameraLink

®

cable solutions are available from Photonfocus.
