Grabbing The Frame | BitFlow

Almost written-off by the introduction of new technology, the venerable frame grabber is alive and well. Here we look at some of the major players.

BitFlow unveiled its first CXP v2.0 frame grabbers at VISION 2018 in Stuttgart

The US company is a global innovator in frame grabber technology for machine vision.

Over the past two years BitFlow has furnished input and direction to the Japan Industrial Imaging Association (JIIA) on the finalization of the new CoaXPress v2.0 (CXP v2.0) standard — an upgrade that will double the speed of the interface used in the inspection of semiconductors, food and beverage, and pharmaceuticals, among others.

“By coordinating with the JIIA on a standardization roadmap BitFlow is in a better position to develop frame grabbers that will reliably perform up to full potential,” explained Donal Waide, Director of Sales for BitFlow.

“Because BitFlow engineers have been actively involved in every detail of CXP v2.0 development we can ensure our customers that the frame grabbers we are introducing at VISION are fully tested and certified to meet the high quality expectations of system designers.”

BitFlow’s first CXP 2.0 frame grabbers were on display the company’s VISION booth. It also conducted live demonstrations of its 2.0-ready Aon-CXP and Cyton-CXP CoaXPress frame grabbers, along with its advanced Camera Link models.

It also displayed the BitFlow BitBox, an I/O device that provides 36 inputs and 36 outputs in a compact, DINrail mounted form factor supporting TTL, LVDS, open collector, opto-isolated and 24V signaling.

Introduced a decade ago, CoaXPress standard v1.1.1 is currently supported by over 50 vendors of cables, connectors, intellectual property, transceivers, cameras, frame grabbers, simulators, range extenders and software. CXP v2.0 will double the current 6.25 Gbps image data transfer rate to 12.5 Gbps, therefore allowing for higher frame rates or larger camera resolutions. The JIIA and BitFlow have concluded CXP v2.0 is necessary for manufacturers to achieve the extremely high levels of quality, cost efficiencies and productivity needed to gain a competitive edge in the global economy.

Among its many proven advantages, CoaXPress allows video, camera control for triggering, and up to 13W of power to be transferred without latency on off-the-shelf coaxial cables up to 100 meters in length or approximately three times that of USB3 or GigE Vision. Also, because CoaXPress relies on standard coax, many such cables previously installed in legacy defense and security systems utilizing analog cameras can be re-used for migrating to digital imaging, eliminating the cost of new cabling.
