AIA’s Global Vision Standards Update: GigE Vision and Camera Link updates

Released in December 2018, the AIA’s latest Global Vision Standards Update provides a look at the latest news surrounding machine vision standards and the products that incorporate them.

The update is the first since January of 2018, so Bob McCurrach, AIA Director, Standards Development, covered a number of items. First, he noted that GigE Vision 2.1 was released by the GigE Vision Technical Committee this past fall, and that one enhancement is the inclusion of multi-part transmission, which allows the sending of more complex data structures. One obvious area where this applies, suggests McCurrach, is for 3D imaging.

In addition, a new mechanical supplement was released by the GigE Vision Technical Committee, which has included requirements for over-molded RJ45-based locking screw cables, as well as specified two smaller connectors for the device of the cable: M12 and iX connectors. This is important, suggest McCurrach, as camera manufacturers strive for ever-smaller cameras.

Next, he noted that Camera Link version 2.1 was released by the Camera Link Technical Committee, with key enhancements including:

• Jack screw requirements clarified
• Bit positions for ALL tap formats documented (chapter formatting improved for ease of use)
• Support has been added for products that emulate the Channel Link chip in their FPGA
• New function added to serial port API which resolves long standing weakness in original function
• Product testing at a PlugFest now a requirement for all version 2.1 products

McCurrach also provided some information on some upcoming international vision standards meetings (IVSM), including the first ever event hosted by the China Machine Vision Union (CMVU), in partnership with BOZHON Precision Industry Technology Co in Suzhou, China. The meetings will take place the week of March 25, after the Shanghai Vision Show.

This Standards Update also contained a call to action of the OPC-UA Regional Working Group and Vision Standards meetings. Learn more about these, as well as how to get more involved, information on the next AIA PlugFests, and more, by viewing the full update.
