24 Camera Hardware Interface
EXSYNC
The EXSYNC signal tells the camera when to integrate and readout the image. 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.
Section 3.7 Setting Exposure Mode, Frame Rate and Exposure Time on page 36 details how to set frame
times, exposure times, and camera modes.
PoCL
When connected to a frame grabber that supports PoCL, the camera can be powered by the frame
grabber through the CameraLink cable. The camera re12V DC power through pins 1 and 26, and
returns to ground through pins 13 and 14. Refer to the Camera Link Connector Pinout section for a
complete pinout description. If power is provided over PoCL, the camera automatically detects PoCL; no
configuration is necessary.
To enable PoCL on the frame grabber, refer to your frame grabber’s documentation.
Note: If power is supplied to both PoCL and the Hirose power connector, the camera will use
the PoCL supply. However, DALSA recommends connecting only one power supply to the
camera.
2.2.4 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
DALSA Camera Link Implementation Road Map, available at www.dalsa.com , for the standard location of
these signals.
Clocking Signal Indicates
LVAL (high) Outputting valid line
DVAL (high) Valid data
STROBE (rising edge) Valid data
FVAL (high) Outputting valid frame
•
The camera internally digitizes to 10 bits and outputs the 8 most significant bits (MSB’s) or all 10
bits depending on the camera’s Camera Link operating mode.

For a Camera Link reference and timing definitions refer to Appendix A on page 75.
