A quick and easy way to expand your PC's port count and to adapt serial devices to your USB PC. Edge port USB-to-Serial converters are intelligent expansion units
that connect to a PC, thin client or server via a USB port. They provide one, two, four, eight or sixteen serial ports, as well as parallel and USB ports on some models. Compatible with most Windows operating systems. No IRQ, I/O address, DMA or memory address requirements. Serial port models require no external power. Models
with USB output ports use an included power supply.
