Works without fail

By John - Measurement Tech.

from Alberta, Canada

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I've been using this model for years in the oilfield measurement industry and it's never failed me. Recently it's been very handy when connecting to Bristol Controllers, as it will allow the program to poll for the local address, where the other adapter I have will not. Just keep an eye on the cord plugged into the back, it has a habit of coming out if your not paying attention.

Great, except for Windows 10

By Serial

from CA

Verified Reviewer

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I've used this adapter for years very successfully with WinXP and Win7. Works perfectly; five stars.

But I cannot get it to work reliably with Windows 10; zero stars. Everything seems OK at first with Win10, but the adapter triggers a blue screen of death from time to time due to a problem in the driver. I can't live with that.

Best USB / Serial Adapter Out There

By Retired Apple SW Engineer

from Idaho

Verified Reviewer

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

Contrary to other posted comments, this device does work with El Capitan. I have two that are on two different computers (an iMac and a MacBook Pro) that receive daily use. About to purchase a third for a relative to use on a Mac Mini. I've deployed these on several Windows systems too. Absolutely 100% reliable and works without a hitch on both Mac OS X and Windows.

Works extremely well!

By divolb

from Tucson, AZ

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I have used this product for over 5 years on both Windows XP and 7 without issue. I have used it to interface several RS232 devices. Make sure to have the driver installed, plug in the device and verify it is loaded in device manager before opening any other software that will use the com port it creates. Do this and you will not have any issues.

Other devices I used would disconnect intermittently and fail to work requiring manual disconnecting and re-connecting, sometimes to a different USB port to get it to work. Not with this product, it has worked for hours at a time without issue.

The most reliable and versatile adapter I have found

By The Old Professor

from Tustin, CA

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I have worked at a university and a biotech R&D company where we had equipment with serial interfaces. The 19HS has worked with the widest variety of units and with the fewest errors of any adapter I have used. Two thumbs up.

It Just Works. VERY Reliable.

By Old-School Hacker

from San Jose, CA

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

I've been using one of these for over 10 years on Win-XP, and it works every time, all the time. If you need to add RS-232 to a machine with only USB, you gotta get one of these.

Best UART adapter

By Shane

from San Jose, CA

Comments about Tripp Lite Keyspan High-Speed USB to Serial Adapter:

Over years of automated embedded device testing these have been the most reliable USB < -> UART adapters for me. I primarily use them from Linux and Mac with pyserial or Device::SerialPort, and sometimes from Windows with FlashMagic. Seems to work fine with Minicom and Screen too.
