USB to RS232 Serial Cable 3.3FT

This cable converts a USB port into a DB9 serial connection using the Prolific PL2303 chipset. It targets technicians and integrators who need to link legacy equipment such as modems, scanners, CNC machines, POS terminals, or barcode readers to modern computers lacking native COM ports.

Sustained data transfer at 1Mbps

The tinned copper conductor and triple shielding maintain signal integrity during continuous operation with cashier registers, PLC controllers, or tax printers. USB bus power eliminates the need for an external adapter, so the link stays active as long as the host port supplies current without additional hardware.

Driver installation required before first use

Windows 11, 10, 8.1, 8, 7, Linux, and Mac OS are supported, but the driver must be downloaded from the Cablecreation website before the cable functions. The adapter is not compatible with cutting plotters or SCM devices, so verify the target equipment uses a standard DB9 RS232 interface before purchasing.
