CoaXPress® technology is an open and royalty-free asymmetric, high-speed, point-to-point open serial communication standard for high-performance machine vision, industrial inspection and traffic monitoring systems. It provides a state-of-the-art method for connecting high-performance, high-resolution cameras to high-speed capture cards—which are also known as frame grabbers—via standard, off-the-shelf 75Ω coaxial cables. This cost-effective solution enables the transmission of data, video and still images; camera control and triggering; and up to 13W of power of power to be delivered via a single cable of up to 100m in length with a standard BNC, micro BNC or HD-BNC connectors.

The data rates are scalable for multiple cables and only limited by the number of cables that can be accommodated in your design. Although CoaXPress technology is designed to meet future imaging challenges, its scalability works both ways, making it usable in a vast number of other applications. Systems that don’t require the highest performance can be built using less expensive components and still take advantage of some of the benefits that CoaXPress technology offers.

CoaXPress 2.0 Is Here


Offering a significant improvement in speed over CoaXPress v 1.1, CoaXPress 2.0 extends the data transfer rate up to 12.5 Gbps for cables lengths of up to 40m, and up to 40 Mbps for bidirectional communications. It supports higher frame rates or higher camera resolutions for developing even higher-performance video imaging systems. Key advantages of this new version of the standard include:

  • In addition to the CoaXPress 1.1 data rates of up to 6.25 Gbps, it supports 10 Gbps (CXP-10) and 12.5 Gbps (CXP-12) data rates and doubles the cable bandwidth so you can use fewer and more flexible cables and fewer frame grabber cards
  • A single camera can send data to more than one frame grabber, which can be located in different PCs
  • The doubled uplink speed of 40 Mbps enables trigger rates over 500 kHz without requiring a dedicated high-speed uplink cable
  • It includes enhanced support for event packets and 3-D data formats in the industry-standard GenICam™ programming interface
  • Support for the compact and robust Micro BNC connector is now available
  • It offers easy migration and backwards compatibility with CoaXPress 1.1 to preserve your investment in previous systems and products
