Functional Description
A block diagram of the CLV-411 is provided in Figure 1-1. The CLV-411 interfaces one
camera to up-to four frame grabbers using standard Camera Link cables.
One frame grabber acts as the master (primary). The master frame grabber receives video
data from the camera, and can also control and communicate with the camera. The
interface between the camera and the master frame grabber utilizes the entire Camera Link
signal set defined in the Camera Link Specification for "base" configurations. This
consists of video data, camera control, and serial communications.
The remaining frame grabbers act as slaves (secondary). The interface between the
camera and the slave frame grabbers utilizes video data only. The slave frame grabbers
receive video data, but cannot control or communicate with the camera.
Some applications require the ability to share control of the camera between the frame
grabbers (i.e. share the master role). CLV-411 allows any of the four frame grabbers to
act as the master. Selection of the master frame grabber is made via the opto-isolated
master select inputs. When the select inputs change, the master frame grabber is
immediately reassigned accordingly. This enables dynamic (i.e. real-time) selection of the
master frame grabber for applications requiring this capability.
Frame grabber 1 is the default master frame grabber whenever the opt-isolated inputs are
not being used. Front panel LED indicators identify the current master frame grabber.
Since the CLV-411 regenerates all signals, it also acts as a repeater and supports an
additional 10 meters of separation between camera and frame grabbers.
The CLV-411 is also compatible with the second Camera Link cable used in the
"medium" configuration, enabling a pair of CLV-411s to be used in parallel to support
medium configuration applications.
The CLV-411 is powered by an external wall plug-in power supply.
