Need to use a serial device with your Mac or PC? Most computers no longer have a 9-pin serial port, so how can you connect serial devices such as network storage devices, switches, routers, GPS devices, barcode scanners, point-of-sale devices and lab equipment? The Tripp Lite Keyspan High-Speed USB to Serial Adapter is a perfect solution and is widely recommended by serial device manufacturers for its dependability, simple plug-and-play operation and device compatibility.

Works as advertised.

University classroom environment.

works good

Plug it in and it works

Product works!!

This product did what I needed it to do - connect an industrial device with an RS232 Serial Port to my laptop that only has USB and Ethernet ports. This should be a no-brainer, but I bought the Belkin Brand first, and it did not work. I borrowed the Keyspan unit from a business partner. It worked first time, so I bought one myself. I actually haven't used mine yet, only my partners. The huge problem with this kind of stuff, is that when the device does not work, you spend hours trying to make it work because you think you are doing something wrong - especially in the industrial world where you are learning your programming software as well. After many wasted hours I find out that my Belkin converter was the problem. The Keyspan unit solved my problem in minutes.

Keyspan USB to RS232

Actually seems to fully comply with RS232 standards, and so works with any remote RS232 equipment. Has associated test and setup options for getting USB behavior for multi usb ports. Many overseas and popular models, don't meet all voltage and current standards and thus aren't fully RS232 compliant. I am an EE and specifically wanted this item and was surprised to find it at Walmart since I consider it to be a technical niche item. JimD

This USB Serial is Good

I use serial communication to control equipments. Have problems with 4 other brand usb-serial adapters until I got this one. The main thing is this adapter can adapt to non-standard baud rate


Great product. I was having issues with all of the prolific based usb to serial adapters on windows7 x64. They were all causing blue screens. This one works flawlessly. A++

Keyspan High-Speed USB/Serial Adapter

I've used this USB/Serial adapter on 3 different ham radios. Each ham radio is from a different manufacture and the USB/Serial adapter worked on all of them without a single problem. I use the interface to download updates to the ham radios as well as control them via my PC. PC OS; Vista

Best Serial to USB Adapter on the Market

In an effort to get two troublesome Serial devices to work, in addition to this Keyspan product, I tested 3 other USB to Serial competitors to this product and one set of Belkin Active USB extension cables (Active extension cables can extend the typical normal 16' USB cable length limitation up to 80' ) All of these worked to varying degrees but the one with which I had the least conflict was the Keyspan - going away. As another review I spotted also noted, the Keyspan accompanying software has a nifty port mapping indicator which shows what you have currently or, better yet, previously installed (and still connectable) on all of your comm ports. This one was the best, and I was pleasantly surprised that the only reputable place which carried it, was Wamart.

works well

Used with laptop to communicate with Fanuc cnc control. Works well.

Good one

It's good. It was little hard to install it on my Windows 7 OS. If you are not tech savvy, I wouldn't recommend it to you.
