CameraLink is a high-speed protocol and hardware set used to transfer real-time images with timing signals from cameras to computers and to send configuration commands and triggers from computers to cameras. CameraLink is implemented using ChannelLink serializers with differential LVDS signaling and shielded twisted-pair cable. The characteristics of CameraLink are defined in the CameraLink standard available from the Automated Imaging Association (AIA) - www.machinevisiononline.org.
CameraLink Framegrabbers. Since computers do not have native CameraLink ports, plug-in board called framegrabbers are required to communicate with cameras. Framegrabbers are currently available for PCI, PCI Express and ExpressCard slots in computers and is some other bus formats such as PC104.
Auxiliary Functions. Framegrabbers that plug into motherboards generally take single slots, however, some cards that have two CameraLunk connectors on their panels need an auxiliary slot to provide panel space for extra connectors used to send and receive non-CameraLink signals like triggering and strobe control. Similarly, ExpressCard framegrabbers may require auxiliary cables for these functions. Always ask if the framegrabber you have selected needs additional parts to accommodate these functions.
Power over CameraLink. Some cameras and framegrabbers are configured to allow camera power to be supplied by the framegrabber over the CameraLink cable. These products are identified by the PoCL designation. For PoCL to work, both the camera and framegrabber must be configured for its use and the cable must be wired to transmit the power. Original CameraLink cables will not transmit power so special PoCL cables must be used.
