Always reliable
We use 6 of these in a training course with different students every time. A driver is required for their laptops they make it easy to find on the support site for download. Simple and reliable.

Best product!
Purchased this adapter to make an old Seiko 220 label printer work on my Win 10 laptop. As soon as I figured that Tripplite had drivers to go with this product, my old label machine worked like a dream. So glad there are products on the market like this serial adapter that provide continued use of old electroni

Rated 5 out of 5 by from Unit no longer functionsThe driver which I tried to updat from your site will not download properly on my laptop. It downloads however it does not load when i open the application. I selected the Windows 7 Beta driver for my USA-19HS interface unit. My laptop does not recognize the unit when i plug it in. The power on indicator lamp (LED) does not come on.

Rated 5 out of 5 by from Great, except for Windows 10I'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.

Rated 5 out of 5 by from Gets the job done!I use this on a day to day basis as a Network Engineer. It's pretty straight forward and definitely gets the job done. I have used others that not as reliable so this is my go-to adapter. I would, however, like to see something a little bit more solid/sturdy. While it's not as fragile as other adapters, I imagine it wouldn't take much to crush or cause the casing to separate. Otherwise, no complaints!

Rated 5 out of 5 by from It worked where others failed!I bought this USB to Serial adapter because I had some equipment that wasn't working with the adapter that I owned previously. This adapter was very easy to set up and everything worked flawlessly and automatically. I have now tried it with all my serial devices and it works with them all. Thank you for a great product
