TRIPP LITE USB to Serial Adapter Cable, USB-A to DB9 RS232, Male-to-Male, 5 Feet / 1.5 Meters, 3-Year Warranty (U209-000-R)

Worked well to connect a laptop to a maintenance cable for a network switch. Good quality cable.

It's pretty basic. You plug it into your computer, and a COM port appears. It does what it says on the tin! I've been using these adapters for years. I hand them out to other techs when I have extras. You plug it in, and it works. Doesn't matter which version of Windows you're running. You don't have to go out looking for drivers. You just wait about 30 seconds if your laptop has never seen one before, and that's it. I really started believing in these when we decommissioned a bunch of monitoring equipment for a large retailer. I pulled one of these from like a dozen different sites. They had been installed for years monitoring embedded devices. Every single one of them worked just fine, and I never heard of a single one going bad out of my service area. There may be other USB serial adapters that are as seamless, but I haven't found one that doesn't need fussing depending on which Windows you're running. (Not tested on Windows 2k or earlier.)

I've been using this DB9 adapter for about 8 months solid now in both Military and civilian environments. From dust and dirt, to repeated stuffing in a cramped bag and left out in 120F heat. I've connected it to Windows XP SP3 (x32), Windows 7 x32 and x64 bit, I even connected it to my ASUS Transformer Prime (TF201) with the Slick USB software and could use it there even! I've connected it to all these devices with NO DRIVERS NEEDED. Every system finds the right driver and automatically uses it. It's been used to connect to GPS devices, Cisco RS232 adapters, survey equipment, SCADA equipment (Wind Turbines), and raw data dump devices, all without fail. I am purchasing another one tomorrow since a customer had some issues and needed one of these. So now I'm a repeat customer. In short, if you need a serial port on a computer/laptop/android device, look no further, this simple, and effective device works every time in some of the most needlessly terrible situations I've put mine though. It works reliably, plain and simple.

simple and easy to use cable. works fine on my work windows 11 laptop.

Best USB to Serial adapter I’ve used. Great build quality and works with everything I’ve used it with.

Well engineered, from functionality to packaging, it worked 1st time, software included, install instructions correct and smooth! Buy it, despite seeing that "one deal " for 3 bucks cheaper... Trust me, I have that "deal"cable sitting on my desk to remind me of the french philosopher and philanderer, Robierre, who lamented, "There is no thing in the World that can't be made cheaper by lowering Quality!". Bonjour and buy American Engineering 🤓

Simple and reliable -- an essential part of my IT toolkit, and I use it frequently. Very happy with this purchase!

I have used many pother brands of USB to serial adapters with mixed results. Every time I use the Tripp Lite version, it just works. No problems, not reloading drivers, no flakiness, etc. It just works. It is also a good value and holds up well to use

Excelente producto la pc lo detecta sin problemas además muy largo

I started using this cable back in 2012 and can 100% rely on it to work all day everyday.

Seems to be a very well made cable. Use it to update my tristar solar charger controller & worked great.

Es un conversor, convierte 232 a usb,

Tried other ones that did not work with Windows 10. This one does using the driver supplied on the CD. I tried downloading the driver from web site and that one did not work.
