UGREEN USB To DB9 RS-232 Serial Female Adapter 1.5m | CR104 | 20201
The UGREEN CR104 (item 20201) is a 1.5 m USB to serial cable, with a USB-A male plug on one end and a 9-pin DB9 RS-232 female connector on the other. It adds a COM port to a computer through USB, so you can communicate with RS-232 serial devices at up to 1 Mbps.

Prolific PL2303 chipset: The cable uses a Prolific PL2303 USB-to-serial chip. After a one-time driver installation it works plug and play whenever you connect it.
Powered by USB: It takes its power from the computer's USB port, so no external power adapter is needed.

Female DB9 connector: The serial end is a DB9 female connector, so it plugs directly into a device or cable that has a DB9 male port.

Shielding and system support: Multi-layer shielding helps keep the serial signal stable, and the adapter is supported on Windows, macOS and Linux.
Who it's for / Works with
Computers without a built-in serial port that need to connect to RS-232 devices with a DB9 male port, such as barcode scanners and serial modems.
Good to know
A driver may need to be installed once before first use. The maximum data rate is 1 Mbps.
