Windows 7 Compatible 32-bit and 64-bit
Fully Serial / RS232 compatible
We proudly boast about our 99% device compatibility ratio with this product! We also stand behind it. You may see others that look like ours, but ours comes with a driver for Windows 7, 32-bit as well as 64-bit.
Our USB to Serial Adapter Cable is used mainly by AV pros and other industrial techs. This cable works great to add a serial port to your new laptop that didn't come with one, and will allow you to work on equipment just like you used to with your old laptop.
Setup is quick and easy. Just plug it in, pop in the driver disk, and be done within a minute or two. We've also included driver downloads on our site in case you want to try those with your current non-functioning adapter.
