histogram (Fig. 5.47) indicates problems, that may be caused either by a defective camera, by
problems in the acquisition software or in the transmission path.

In robots applications, the stress that is applied to the camera 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.

5.10 Double Rate (DR1 cameras only)

The Photonfocus DR1 cameras use a proprietary coding algorithm to cut the data rate by
almost a factor of two. This enables the transmission of high frame rates over just one Gigabit
Ethernet connection, avoiding the complexity and stability issues of Ethernet link aggregation.
