USB 2.0 to RS232 serial cable with PL2303 chipset

The Manw adapter converts a USB 2.0 port into a standard DB9 serial connection. A PL2303 chipset handles the signal translation and supports data rates up to 1Mbps. The cable measures 6.6 feet and draws power directly from the USB bus. Driver installation is required before use.

For legacy serial equipment on modern computers

This cable suits technicians connecting modems, CNC controllers, POS terminals, barcode scanners or label printers that only offer a DB9 port. It is not for users who need a native serial port without driver setup. It is also not for cutting plotters or SCM devices, which the manufacturer lists as incompatible.

PL2303 chipset with broad OS support

The Prolific PL2303 chipset provides compatibility with Windows 11, 10, 8.1, 8, 7, Linux and Mac OS. Drivers must be downloaded from the supplier website before the adapter will function. This software requirement is the single factor that determines whether the cable will work in a given environment.

Questions about this item

Which cable length should I choose for this adapter?

This adapter is a single 6.6 ft cable with a USB 2.0 connector on one end and a DB9 male plug on the other.

What does the 1 Mbps USB 2.0 rate mean when I connect a serial device?

The link runs at USB 2.0 full-speed, so the PL2303 chipset can move serial data up to 1 Mbps between the PC and the DB9 device.

Does the RS232 DB9 interface cap the speed in practice?

Yes, the DB9 serial side limits throughput to the 1 Mbps provided by the PL2303 chipset, even though the USB 2.0 port can handle more.
