Product Description

From BabyTalk Editors

Keyspan by Tripp Lite’s USA-49WG USB 4-Port Serial Adapter is a simple, reliable, inexpensive solution for connecting serial devices to your USB computer. It’s the easy way to add serial ports to a computer without the hassle of installing a serial card, turning off the PC, or connecting an external power adapter. The USA-49WG draws power directly from your computer through the USB connection. Simply plug it into the USB port of your computer using the included cable, install the software and you’re ready to connect up to four serial devices. Five LEDs (one red, four green) display the USB and DB9 port status at a glance. Featuring data transfer rates up to 460 Kbps, the USA-49WG can be used with any RS-232 serial device—networking equipment, modems, GPS devices, cell phones, hand-held scanners, point-of-sale systems, touch screens, medical and scientific instruments, industrial process control devices, UPS systems and more.

Applications
The USA-49WG is ideal for industrial and enterprise markets where there is a need to connect serial device to a PC for process control, data collection or point-of-sale applications. It is also ideal for connecting modems, fax modems or terminals to a server.

5.0 out of 5 stars Works fine, June 9, 2008
This review is from: Keyspan by Tripp Lite USA-49WG 4 port USB DB9 Adapter (Personal Computers)
I've been using this USB serial interface for a couple of years now. I've used it under Windows XP, Fedora and Ubuntu Linux. The Windows XP drivers are available on Keyspan's website. Fedora and Ubuntu (except version 7.10) include the drivers in the standard distribution.

The serial interfaces are solid, providing good RS-232 drive levels. The interfaces can also handle decent bit rates. I've used it up to 115200 BPS. It's also very convenient the way it is packaged. Especially in embedded systems programming, it's nice to have four serial ports right on your desk top with just the one USB cable running to the computer.

5.0 out of 5 stars Good News - Tripplite/Keyspan has 64bit windows drivers, March 23, 2010
This review is from: Keyspan by Tripp Lite USA-49WG 4 port USB DB9 Adapter (Personal Computers)
This is the absolute best USB to Serial Comm port adapter.
You'll never need to unplug and replug it in.
You'll never need to go into Device Manager and change the COM port number.
It is a good performer and works well.

Tripplite/Keyspan has 64 bit driver for windows XP/Visa/W7.

I have used this device on 32 bit Vista and on 64 bit Vista.

5.0 out of 5 stars Reduces Clutter, June 20, 2008
Amazon Verified Purchase(What's this?)
This review is from: Keyspan by Tripp Lite USA-49WG 4 port USB DB9 Adapter (Personal Computers)
I have used Keyspans individual port adapters for several years. They work flawlessly and are quite fast. I do a lot of work on high speed serial devices running without flow control. The devices keep up.

I found that I often had 4 single Keyspans cluttering my desk. I wanted this device. When I finally found it, it was a no-brainer. It works flawlessly. (I had hoped it would be less expensive than 4 singles - and it is - just a little.)

A nice little benefit is I use their static mapping tool to make the ports appear as COM11 thru COM14, eliminating past confusion about which port goes with which device.

Serial is officially a legacy device. New PCs don't have serial ports. But, if you have a lot of serial devices to manage, this is a great way to simplify cabling and management hassles.
