IMPORTANT:
This camera uses the
falling
edge of EXSYNC
to trigger line readout,
unlike previous DALSA
cameras, which used the
rising edge.
EXSYNC (Triggers Line Readout)
EXSYNC is an optional input signal that can be used to trigger the line readout rate. This
camera uses the
falling edge of EXSYNC
to trigger line readout.
Note:
EXSYNC should not be clocked faster than the camera’s specified maximum line
rate. The camera ignores the EXSYNC pulse until it has completed reading the last line
out.
2.6 Data Bus, 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
vfm.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
IMPORTANT:
This camera’s data should be sampled on the
rising edge of STROBE.
Digital Data
The camera digitizes internally to 10 bits and outputs either all 10 bits or the most
significant 8 bits in LVDS format on the Camera Link connector.
Note:
Due to flat-field correction calculations, certain digital numbers will be unavailable
when outputting 10 bits with flat-field correction enabled (i.e. you will experience
missing codes).
