In order to download dives or upload new firmware or features, Vision rebreathers produced between 2005 and October 2015 require a serial/USB conversion cable to connect the download/upload bridge interface to a USB port on your PC or Mac.

Prior to Jan 2013, the cable shipped with the Vision was manufactured by a company called Prolific/Gembird. Over the years, they tried to ensure compatibility by updating their drivers but by Windows 7 it became clear that the cable could no longer be used for uploads taking in excess of a couple of minutes, with some users experiencing connection issues as well. From January 2013 AP changed the supplied cable to an FTDI chipped conversion cable which self-seeks the correct driver and makes plug-and-play a reality. The AP part No. is EV91/04A - Serial to USB Bridge Interface Cable.

If you have a Prolific/Gembird grey/cream coloured serial/USB cable, the easiest solution is to just upgrade the cable to the EV91/04A.

In May 2016 a customer claimed to have solved the issue with the Prolific cable and referred to the attached web-article, (not tested by AP): Download Guide (Microsoft Word)
