Connected new PC’s up to old CNC machines no problem
Highly recommended.Using these we were able to replace the ancient PC’s connected to our CNC machines with passively cooled SFF PC’s.Didn’t have any issues with setup, and they’ve been in use for over a year now without issue.

Easy to install with very good instructions.
Worked perfectly on Windows 10 first time to connect an old peripheral to the USB port. Windows 11 driver also available. Excellent live chat with the manufacturer too.

Works with Win8.1, Win 10, Linux and Cisco kit
This adapter is based on the Prolific PL2303 RA chipset – this is advertised as Win8.1, Win 10 and Linux compatible.The item arrived very quickly and looked exactly as the picture on this product page.When I first bought this adaper, I plugged it into my Win8.1 laptop and it was discovered straight away. It was assigned COM3: and it did not have a “!” or “?” in the Device Manager view. Since then I have upgraded to Win 10 and I can report that it just worked, with Win 10 installing the same latest driver as can be found on the Prolific website. Additionally, this cable has just worked without any fuss on every Ubuntu Linux build I have tried it in.Using PuTTY I have been able to connect to my Cisco ASA, routers, switches and Netscreen/Juniper firewalls witout any problems.[Edit: Updated 2016 to correct the Prolific chipset identfication, and add Win 10 & Linux compatibility observations.]

Useful cable interface from Star Tech
If you’ve a DB 9 port on your vintage PC and need to connect to a usb device then this cable interface would do the job. I use this serial cable with Windows 10, and 7 but drivers need to be loaded. Back in the day a lot ofLaptops had a db9 port for connecting to other devices for configuration. Nowadays, all laptops are usb or rj45.
Mrs T A Bull –
Great
Very, very happy, thank you
William Myson –
May suit some situations.
I made a huge mistake. I thought it had a female connection on the serial plug. It is a male. That is my fault as the product seems to be of excellent quality and in the right situation would be a good buy.
