Keyspan High-Speed 4-Port DB9 Serial Serial DB9 to USB Adapter Hub
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.
