CoaXPress (CXP) is an asymmetric high-speed serial over coaxial cable standard for the transmission of video and still images, scalable over single or multiple coaxial cables. The most common application is interface camera to computer interface via frame grabber, on applications such as Machine vision performing automated acquisition and analysis of images.
When connected to a CoaXPress camera, a high-speed downlink of up to 12.5Gb/s per cable for video, images and data is enabled, plus a lower speed of 41.67Mb/s uplink for communications and control requiring no additional external power supply or cables, with cable lengths exceeding 100m may be achieved. CoaXPress combines the best features of each of these existing interfaces into a single solution:
- Data rates up to 12.5Gb/s over a single coax cable and up to 50Gb/s when using four cables.
- A single cable supports data transfer, camera control, trigger, and power supply (up to 13W)
- Flexible, reliable, and cost-effective cable solution, through use of standard coax – e.g RG59 and RG6.
- Precise triggering capability, low and fixed latency
- Plug-and-play capability detects camera to grabber system automatically
- Supports GenlCam”s standard protocol for higher-level control
Acquire Images from the Fastest and Highest Resolution Cameras
Euresys Coaxlink Frame Grabber Series Coaxlink is a series of CoaXPress frame grabbers. They acquire images from the fastest and highest resolution cameras on the market. The Coaxlink cards use standard coaxial cables and the latest DIN 1.0/2.3 connectors featuring a robust push/pull latching system and the Micro-BNC (HD-BNC) connectors with trusted push and turn, bayonet-style positive lock, for quick and easy connects, and disconnects for reliable industrial application. The Coaxlink series targets applications requiring high data rates, high frame rates, and consistent real-time timings but also longer cable length, greater cable reliability, and flexibility. Typical examples of applications for the Coaxlink frame grabbers are AOI, SPI, and 3D SPI, printing inspection, Flat Panel Display, or glass inspection.
Acquire images from the fastest and highest resolution cameras The Coaxlink cards benefit from the highest data acquisition rate in the industry. They are able to sustain up to 12.5Gbit/s over a single Coaxlink cable.
This leads to an impressive data transfer rate of 50Gbit/s with the 4 cable connections.
Multiple-camera Applications Support
The Coaxlink frame grabbers support multiple-camera applications. Coaxlink Octo is designed to acquire images from up to 8 of CoaXPress cameras. 4 cameras can be connected to Coaxlink Quad, and 2 cameras can be connected to the Coaxlink Duo. Multiple Coaxlink cards can be used simultaneously in a single PC and all the cameras connected can be optionally synchronized. Use standard coaxial cables
Use Standard Coaxial Cables
Coaxial cabling allows for longer distances between the camera and the frame grabber. Moreover, these cables offer greater reliability and flexibility. At full CXP-12 speed, a cable of up to 40 meters can be used, at CXP-6 half-speed, a distance of up to 72 meters can be achieved and at CXP-3 quarter-speed, a distance of up to 100 meters can be achieved. This clearly reduces the need for repeaters.
Robust Connectors for Reliable Connections
A single cable supports data transfer, camera control, trigger, and power supply (up to 13W) simplifying the integration and decreasing the costs and the CoaXPress standard offers the real-time triggering capabilities required by industrial machine vision applications. Moreover, the Coaxlink cards take advantage of the robust push/pull latching system of DIN 1.0/2.3 connectors, and the Micro-BNC (HD-BNC) connectors with trusted push and turn, bayonet-style positive lock, for quick and easy connects and disconnects for reliable industrial application.
Direct GPU Transfer
Direct GPU transfer eliminates unnecessary system memory copies, lowers CPU overhead, and reduces latency, resulting in significant performance improvements in data transfer times for applications. Sample programs for AMD DirectGMA and NVIDIA (CUDA) are available.
Memento Event Logging Tool
Memento records an accurate log of all the events related to the camera, the frame grabber and its driver as well as the application. It provides the developer with a precise timeline of time-stamped events, along with context information and logic analyzer view. It provides valuable assistance during application development and debugging, as well as during machine operation.
