CoaXPress v2.0 is an interface for connecting cameras (devices) to frame grabbers (hosts). It utilizes a primary connection, supplemented by optional extension connections, to form a communication link. Each connection within this link supports data rates up to 12.5 Gbps, with both data transmission (device to host) and control signals (host to device) carried over a single coaxial cable.
