Product Details
The USA-49WG Keyspan high-speed 4-port USB-to-DB9-serial adapter hub allows you to connect as many as four 9-pin serial devices to a computer or laptop with a USB Type-A port. This kit includes a detachable 6-foot USB cable and supports data transfer speeds up to 460 kbps, making it four times faster than a built-in serial port. With five LEDs displaying port status at a glance, the adapter can operate multiple devices simultaneously, such as networking equipment, modems, GPS devices, cellphones, hand-held scanners, point-of-sale systems, touch screens, medical and scientific instruments, industrial process control devices, and UPS systems. The device requires no external power supply and can be used with a USB cable up to 16 feet long. It is compatible with Windows (XP and later) and Mac OS X (10.6 through 10.13) and includes Windows Line Monitor and Data Trace software. The system requirements specify that a USB port is needed.
