Recently, we bought two model 325 and downloaded the usb driver from Lakeshore website. However, the driver doesn't work. I am using Windows 10 laptop and connected to Lakeshore RS232 interface.
Where can I find the correct USB driver for lakeshore model 325?

Hello!
Are you possibly referring to our Model 335? The Model 325 does not have a physical USB connection.
If we are dealing with a Model 335, try downloading the drivers directly from Microsoft update.
Best Regards, Ogi K.

Sorry for the confusion, It is Model 325 and I am using USB to RS232 converter to connect my laptop to RS232.

No problem, I understand what you're trying to configure. You will need to find the drivers of that converter that you have. There are so many of different brands available in the market. Note that we've seen issues with these converters too.. Some seem to work just fine and some simply don't work. After you find the driver on the internet for your specific converter, and install it, I would suggest making sure that you try communicating with the instrument using our communications utility that can be downloaded at the link below. This will be the best and easiest way to confirm that your converter works. www.lakeshore.com/products/pages/icu.aspxIf you have any other questions, please let me know or contact us via phone: 614-891-2243, option 2 for service Thanks and Regards, Ogi K.

I downloaded and installed the usb-serial converter driver. When using the 'lakeshore communications utility', there is no return string after sending '*idn?' command. Please attached screenshot. The converter I am using is Prolific with PL2303 chipset. Is that mean the converter is not compatible? Do you have any suggested converter?

There is one more thing, and I'm hoping this is it, why this is not working. The serial cable that you're using: is it a null modem cable, which it needs to be? On this type of cable, pins 2 and 3 are swapped on each end. You can see a diagram in the Model 325 manual in section 8.7.1 in the first schematic of that section.

Our cable is not null modem cable, and I guess that explains it. I may need to buy one, or just wait for the GPIB adapter to arrive.
Thank you.

Of course - let us know if you continue having connectivity issues after you receive one of the two you suggested.
