Camera Link cable quality and length
The maximum allowable Camera Link cable length depends on the quality of the cable used
and the Camera Link strobe frequency. Cable quality degrades over time as the cable is
flexed. In addition, as the Camera Link strobe frequency is increased the maximum
allowable cable length will decrease. We do not guarantee good imaging performance with
low quality cables of
any
length. In general, we recommend the use of high quality cables
for any cable length.
The following table lists some results achieved using the cameras and a selection of cables
and frame grabbers:

Input signals, Camera Link
The camera accepts control inputs through the Camera Link SDR26F connector. The camera
ships in internal sync, and internally programmed integration.
EXSYNC (Exposure Start)
Line rate can be set internally using the GenICam features. The external control signal
EXSYNC is optional and enabled through the user interface. This camera uses the falling
edge of EXSYNC to start the exposure period.
The EXSYNC signal tells the camera when to integrate the image, followed by the readout.
It can be either an internally generated signal by the camera, or it can be supplied
externally via the serial interface. Depending upon the mode of operation the high time of
the EXSYNC signal can represent the integration period.
Note
: The EXSYNC signal is measured at CC1 and will give a “true” measurement (i.e. within
the measurement resolution of 25 ns) even though the camera will only trigger at a
maximum of 33 KHz.
Output signals, Camera Link clocking signals
These signals indicate when data is valid, allowing you to clock the data from the camera to
your acquisition system. These signals are part of the Camera Link configuration and you
should refer to the Camera Link Implementation Road Map, available at our
, for the standard location of these signals.
