This USB 4-port Serial Adapter is designed to make serial port expansion quick and simple. Connecting to a USB port on your computer or USB hub, this USB 4-port Serial Adapter instantly adds 4 serial communication ports to your system with easy plug-and-play and hot-plug features.

Plugging the USB Serial Adapter into the USB port, the adapter is automatically detected and installed. There is no IRQ & COM port conflicts, since the ports don\'t require any additional IRQ, DMA or memory on the system. The RS-232 serial ports function as native Windows COM ports, and are compatible with Windows serial communication applications. Each port is individually configurable.
