Data Port Summary
The Camera Link interface has three configurations. A single Camera Link connection is limited to 28
bits requiring some cameras to have multiple connections or channels. The naming conventions for the
three configurations are:
•
Base: Single Channel Link interface, single cable connector.
•
Medium: Two Channel Link interface, two cable connectors.
•
Full: Three Channel Link interface, two cable connectors.
A single Camera Link port is defined as having an 8-bit data word. The "Full" specification supports 8
ports labeled as A to H.
