Status Indicator (CameraLink
®
cameras)
A dual-color LED on the back of the camera gives information about the current status of the
CameraLink
®
cameras.
LED Green
Green when an image is output. At slow frame rates, the LED blinks with the
FVAL
signal. At high frame rates the LED changes to an apparently continuous
green light, with intensity proportional to the ratio of readout time over frame
time.
LED Red
Red indicates an active serial communication with the camera.

Data Interface
The CameraLink
®
standard contains signals for transferring the image data, control
information and the serial communication.
Data signals:
CameraLink
®
data signals contain the image data. In addition, handshaking
signals such as
FVAL
,
LVAL
and
DVAL
are transmitted over the same physical channel.
Camera control information:
Camera control signals (CC-signals) can be defined by the camera
manufacturer to provide certain signals to the camera. There are 4 CC-signals available
and all are unidirectional with data flowing from the frame grabber to the camera. For
example, the external trigger is provided by a CC-signal (see Table 5.3 for the CC
assignment).
CC1
EXSYNC
External Trigger. May be generated either by the frame grabber itself
(software trigger) or by an external event (hardware trigger).
CC2
CTRL0
Control0. This signal is reserved for future purposes and is not used.
CC3
CTRL1
Control1. This signal is reserved for future purposes and is not used.
CC4
CTRL2
Control2. This signal is reserved for future purposes and is not used.

Pixel clock:
The pixel clock is generated on the camera and is provided to the frame grabber
for synchronisation.
