USB 2.0 to RS232 serial adapter

This cable converts a standard USB 2.0 port into a DB9 serial connection for legacy equipment. It targets technicians and hobbyists who must link cash registers, CNC controllers, PLCs, barcode scanners, label printers or older modems to modern computers. The 1-metre length suits bench or counter setups.

USB 2.0 bandwidth and driver constraints

The adapter runs at USB 2.0 speeds with a 1 Mbps serial data rate, limiting throughput for high-volume logging. Windows 8.1 and 10 install drivers automatically when online; Windows 7, Vista, XP, 2000, macOS 10.6+ and Linux kernel 2.4.31+ require manual installation from the supplied CD. It does not support cutting plotters or SCM devices.

PL2303 chipset and DB9 pin-out

A Prolific PL2303 chipset handles the USB-to-serial translation and draws power from the bus, so no external supply is needed. Tinned copper conductors with triple shielding protect signal integrity over the cable run. The DB9 female connector presents the full RS-232 modem control set — TxD, RxD, RTS, CTS, DSR, DTR, DCD, RI and GND — matching standard pin-outs for most industrial gear.

Questions about this item

Which cable length should I choose for this adapter?

The adapter comes in a single 1M length with a USB 2.0 male connector and RS232 female DB9 port, so no other length option is offered.

What does the 1Mbps data transfer rate mean when the adapter is connected?

It indicates the maximum serial throughput the PL2303 chipset can sustain over the USB 2.0 link when communicating with modems, scanners, CNC controllers or other DB9 devices.

What does the USB 2.0 interface cap in practice?

The USB 2.0 connection limits the serial link to 1Mbps and supplies bus power, so no external adapter is needed for the RS232 device.
