Connection Lost - Windows 10 - Dell Optiplex 3060 Micro

[FBro]

I'm facing a connection lost issue while acquiring data from a Yokogawa DA100 old hardware. This same application was working fine with the previous PC (Windows 7), but recently the company migrate all the platforms to Dell Optiplex 3060 or 3070 Micro, which is a smaller version with on Windows 10.

With Windows 7 at the previous machine the application runs very smoothly but currently in very distinct moments, which I couldn't find a pattern, the connection is lost (please see the picture). This configuration uses a USB to RS232 converter which for sure could be part of the problem. But I have the same issue happening in other machines that are directly connected to the hardware through the USB port without any converter. And also the problem is happening more rarely with the Ethernet connection in another application, but still happening. I'm trying to figure out if this is a problem with Windows 10 configuration (I already tried to put all energy setups to the maximum performance with no results) or a problem with the PC chipset.

Have anyone faced a similar issue?

Thanks in advance.

Hi

I would first check the USB powering. Windows is famous for shutting that down when it thinks the device is not being used.

Go to power management in windows and never let windows shut down power on usb.

goto power plans, select the active one and goto advanced 

Control Panel\All Control Panel Items\Power Options\Edit Plan Settings  select advanced here

Hi, Albert.Geven,

Thank you for answering. I've already tried that. Now I just changed also the hard disk to never shut down and also the PCI Express to not manage the power. I'm not sure if either of these last changes will make any difference, it's just a test 'though. If it works I'll inform here.

Neither of the options of energy management had any effect on the problem. In order to test if there was any problem with the "USB to RS232" adapter I returned the old PC with Windows 7 and it ran smoothly. My guess is that there is something with the Chipset or bus of this new Optiplex 3060 Micro. I'm trying a solution with the IT team with a different PC. As soon as I find a solution I'll inform here.

Could be an issue with the USB-RS232 converter compatibility between Win10 and Win7. Some support was dropped in Win10 for older chipsets.
