Fujitsu USB to Serial Adapter Cable RS-232 DB9 1.8 m Black

Many modern computers lack a native RS-232 serial port, yet countless industrial devices, POS terminals, and networking equipment still rely on this legacy interface. This USB to serial adapter cable bridges that gap, allowing you to connect your serial peripherals to a USB port without opening the chassis or installing an expansion card.

Who is it for

IT technicians, system integrators, and hobbyists who need to configure routers, switches, modems, or industrial controllers from a laptop or desktop that only has USB ports. It is also ideal for connecting legacy point-of-sale hardware, barcode scanners, and laboratory instruments.
