Rated 5 out of 5 by from I would but it again AND recommend it to all my friends! Could not be happier with my new Tripp Lite USB serial cable. Although my US19HS was old faithful, this all-in-one model is much more convenient. 5 Stars & 2 Thumbs up.

Rated 5 out of 5 by from Great Product I recently upgraded my computer. Now I have no 9 pin serial port. I needed to interface with a gas monitor to download logged data. I plugged in the U209-000-R and it connected immediately with no problems. It is a great product.

Rated 5 out of 5 by from From blues to rocking it! I received this adapter as a replacement for a USA-19HS that kept BSODing my main prod machine while working in Putty. Even though I had purchased it years ago, the kind folks at the Tech Support division were able to assist me in troubleshooting and ended up sending me this one instead. In all honesty I did not expect the level of commitment and quick response I got, so thank you Tripp Lite. So far it works as expected and have not had any issues at all, even with the latest installment of Windows 10.

Rated 5 out of 5 by from Excellent quality of construction This adapter cable definitely exceeded my expectations where quality of construction is concerned. In all other respects, it was just what I needed and wanted. It would've been ideal if I could've found a DB9F version of the same cable, but that's my only possible quibble.

Rated 5 out of 5 by from Tried One, Bought Five If you purchase the cute blue USB to RS-232 adapters from China, you will be sorry sooner or later. They don't even come close to meeting the RS-232 spec, using zero volts as a cheap substitute for the minus 3 to minus 15 volts specified for the "mark" voltage. My radio demo was going down in flames until I changed to a Tripp-Lite U209000R that provided a "mark" voltage of minus 8, right in the middle of the specification values. I'll never go for "cheap" again.

Rated 5 out of 5 by from Works as it should once correct drivers are installed This is just a typical USB-Serial adapter that works great for those old Serial devices or as a console cable connection It does include the newer generation Prolific 2303HXD chip. If you're using this on Windows 8 or 8.1 download the drivers from the Prolific website and manually install them. The drivers that Windows installs cause crashes when using Putty. And the drivers on Tripp-lites' site didn't work at all.

Rated 5 out of 5 by from Have to unplug and replug This converter needs to be removed from the USB port and replaced into the port sometimes for the PC to fully recognize it. For the price, it is OK.
