Mark Renner Posted May 13, 2013 Report Share Posted May 13, 2013 I have had Windows 8 Running Visilogic Software successfully for the past 6 Weeks. After an issue with our Domain we had our IT support company change Passwords and had to re-join notebooks to our Domain. Once we did this, we were unable to communicate with our Vision PLC's via Serial using Prolific USB-Serial Converter. We are using latest drivers and correct chip set. We have a Communications Driver Error (206). I have tried separate Windows 8 notebook with same result. I run Visilogic software as Administrator and same result. Software runs up fine but can not communicate. Have tried other cables and checked that worked on XP machine. Any Ideas. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted May 15, 2013 MVP 2023 Report Share Posted May 15, 2013 You've probably already checked this, but confirm that the COM port didn't change. Go into Device Manager and check which COM port your USB-Serial Converter is using and make sure it matches the one in the VisiLogic Communication Settings. Also, while you're there, make sure the USB-Serial Converter is enabled and functioning properly in Device Manager. Quote Link to comment Share on other sites More sharing options...
External Moderators Nacho Posted June 4, 2013 External Moderators Report Share Posted June 4, 2013 A customer of mine have the MJ10-22-CS35 usb-rs232 converter from Unitronics. the converter was working in Windows XP but now he have a new laptop with Windows 8 64 bits and the converter doesn't work. Do you know where to get the drivers for Windows 8? Is there anyone with Windows 8 and MJ10-22-CS35? Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted June 6, 2013 MVP 2023 Report Share Posted June 6, 2013 The MJ10-22-CS35 uses the Prolific PL2303 chip. The latest driver is available from Prolific's website- http://www.prolific.com.tw/admin/Technology/GetFile.ashx?fileID=232 I've had to go to this site more than once to keep up with Microsoft's updates.

External Moderators Nacho Posted June 7, 2013 External Moderators Report Share Posted June 7, 2013 Hi Joe, the link is broken. Thanks anyway but I think there is not support for Windows 8 for the PL2303. Quote Link to comment Share on other sites More sharing options...

I hate when that happens Try the news on Prolific's home page- http://www.prolific.com.tw/US/news.aspx I just looked at it and there's an announcement about the release of their Windows 8 driver for the PL2303.
