Product Description

An external plug-and-play solution to add up to four RS-232 serial devices to a USB-enabled computer. Use for cellphones, PDAs, digital cameras, modems, or ISDN terminal adapters through your USB ports. Many newer computers, particularly laptop computers and handheld devices, no longer include the legacy serial ports, and desktop computers have reduced the number of serial ports supported. Users with serial devices may find themselves unable to communicate with installed equipment. This adapter is a perfect accessory for Microsoft® Surface® products and other leading laptops.

The four DB9 serial ports ensure you'll have the connections you need, when you need them. It can be conveniently powered by the external power adapter (included) or by USB bus power without the need for an external power supply. Energy-saving USB suspend-and-resume features are supported. Gives you additonal RS-232 ports while it frees your RS-232 port for other uses.
