USB to RS232 adapters (HIGH SPEED)

SKU USB2-H-1001-M

Our Hi-Speed USB to RS232 adapters make it quick and simple to connect RS232 devices to a USB port on your computer. These adapters use Hi-Speed USB for reduced latency and improved throughput. RS232 is widely used in a range of legacy and new equipment, but most computers don’t have physical RS232 ports nowadays. With a variety of port numbers and enclosure styles and easy to install drivers for a range of operating systems, these adapters are ideal for adding one or more RS232 ports to your computer.
