Kestas Posted June 26, 2013 Report Share Posted June 26, 2013 Hi, This is my first topic in this forum I have question about U90 Ladder and windows8. I cannot connect my Laptop to Unitronics M91-2-R34 (checked all possible variations of ports, baud rates, stop bits and so on). User Account Control (UAC) settings is turned off. I am using Prolific USB to Serial converter. This converter can work with windows 8. Is U90 Ladder working with windows 8? Perhaps somebody can help for me...

R.Mozes Posted June 26, 2013 Report Share Posted June 26, 2013 Dear Sir, Which Windows 8 version are you using? (32 or 64bit) here is the link for both versions: https://unitronics.exavault.com/share/view/1j3m-glck37nv-1lljo5h make sure to remove the current driver>disconnect the USB cable>reboot your pc>install new driver>then plug the USB Cable i hope it helps..

Kestas Posted June 26, 2013 Author Report Share Posted June 26, 2013 Dear Sir, Thank You for quick answer. I am using 64 bits version of Windows 8. I am reinstalled prolific driver (from https://unitronics.exavault.com/share/view/1j3m-glck37nv-1lljo5h ) as You recommended, but situation is the same. In the Device Manager, Prolific USB-to-Serial Com Port (COM5), set correct. When I checked with "Check PL-2303 chip version v1002" com port 5 I get: This is a PL-2303 RA chip. In the U90 Ladder I set Baud rate-9600, Parity-None; Stop Bits-1; Data Bits-8 and Flow Control- None, com 5 (the same configurations are in Prolific settings). Then I trying to get PLC settings, I am got error- (2) U90Ladder: Communications could not be established due to one of the following: *Cable connections are not secure. *Timeout is too short. Incorrect communication settings. Check your cables and communication settings and try again. Kestas Quote Link to comment Share on other sites More sharing options...

Ardivaba Posted January 22, 2016 Report Share Posted January 22, 2016 Are you certain that the issue is not with your Profilic drivers? They have to be old ones from 2008. Look at this video here: The download link to old drivers is in the description. Apparently they decided to disable support for Windows 8+ so that people would buy new cables but fortunately old drivers still work with Windows 8 and 10. U90 works nicely on my Win8.
