Data 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 ,
http://vfm.dalsa.com/docs/appnotes/00450-00_03-
32_DALSA_Camera_Link_Road_Map.pdf
, for the standard location of these signals:
Clocking Signal Indicates
LVAL (high) Outputting valid line
DVAL (high) Valid data
STROBE (rising edge) Valid data
See Appendix A for the complete Camera Link timing, DALSA Camera Link
configuration table, and refer to the DALSA Web site,
http://vfm.dalsa.com/docs/appnotes/00450-00_03-
32_DALSA_Camera_Link_Road_Map.pdf
, for the official Camera Link document.
Input Signals
The camera accepts an EXSYNC control input through the Camera Link MDR26F
connector. External control signals are optional and enabled through the serial interface.
EXSYNC (Triggers Readout)
EXSYNC is an optional input signal that can be used to trigger the frame rate. Depending
on the camera’s exposure mode setting, it can use either the rising or falling edge of
EXSYNC to trigger frame readout. Refer to the following table for details.
Table 5: EXSYNC Edge Description
Mode EXSYNC Edge Description
4 The rising edge of EXSYNC begins camera exposure. The falling edge begins
readout.
6 The falling edge of EXSYNC initiates camera exposure.
For more information on camera exposure modes, including timing diagrams, refer to
section 3.7 Setting Frame Rate, Exposure Time, and Exposure Mode on page 25.
NOTE:
EXSYNC should not be clocked faster than the camera’s specified maximum frame
rate. The camera ignores the EXSYNC pulse until it has completed reading the last line
out.
IMPORTANT:
This camera’s data
should be sampled on
the rising edge of
STROBE.
