Input Signals, Camera Link

The camera accepts control inputs through the Camera Link MDR26F connector.
i The camera ships in internal sync, internal programmed integration (exposure mode 2).
EXSYNC (Triggers Line Readout)
Line rate can be set internally using the serial interface. The external control signal
EXSYNC is optional and enabled through the serial interface. This camera uses the falling
edge of EXSYNC to trigger line readout. Section 3.2.1 Exposure Mode, Line Rate and
Exposure Time details how to set frame times, exposure times, and camera modes.

Output Signals, Camera Link

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 DALSA Camera Link Implementation Road Map, available at
http://vfm.dalsa.com/, for the standard location of these signals.
IMPORTANT:

• The camera internally digitizes 12 bits and outputs 8 MSB or all 12 bits depending on
the camera's Camera Link operating mode. Refer to section 3.3.1 Setting the Camera
Link Mode for details on setting the Camera Link configuration.
• For a Camera Link reference refer to Appendix A on page 71.
