Piranha Color Camera 15
2.5 Camera Link Data Connector
Figure 3: Camera Link MDR26 Connector
Input Signals, Camera Link
The camera accepts control inputs through the Camera Link MDR26F connector.
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 pixel readout.
Direction Control
You control the CCD shift direction through the serial interface. With the software
command,
scd
, you determine whether the direction control is set via software control
or via the Camera Link control signal on CC3.
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 Camera Link Roadmap, available from the Knowledge Center
on our website here , for the standard location of these signals.
Clocking Signal Indicates
LVAL (high) Outputting valid line
DVAL (high) Valid data (unused, tied high)
STROBE (rising edge) Valid data
FVAL (high) Outputting valid frame (unused, tied high)
 The camera internally digitizes 12 bits and outputs the 8 MSB or all 12 bits
depending on the camera’s Camera Link operating mode.
2.6 Camera Timing
The Piranha Color camera uses a base or medium Camera Link interface.
Base Configuration
A base configuration uses 1 MDR26 connector and 1 Channel Link chip. The main
characteristics of the base configuration are:
 Ports supported: A, B, C.
IMPORTANT:
This camera’s
data should be
sampled on the
rising edge of
STROBE.
