UGREEN USB2.0 to RS232 Serial Adapter (no built-in cable) | 80111
The UGREEN CM326 (item 80111) is a compact USB to RS-232 adapter without a cable: a USB 2.0 Type-A male plug on one side and a DB9 RS-232 female connector on the other. It gives a computer without a serial port a COM connection to serial devices at up to 1 Mbps.

Cable-free, compact design: The adapter plugs straight into the USB port with no lead in between, which keeps it small and easy to carry in a laptop bag. If the device is further away, you can add your own DB9 serial cable.
PL2303RA chipset: Inside is a Prolific PL2303RA USB-to-serial chip that handles the conversion between USB and RS-232.

Windows, Mac OS and Linux: The adapter is supported on Windows, Mac OS and Linux computers, so the same adapter can move between different machines.
Who it's for / Works with
Legacy serial and industrial equipment with an RS-232 DB9 port that needs to connect to a modern computer through USB.
Good to know
The adapter has no built-in cable; if the serial device is not right next to the computer, use a separate DB9 serial cable.
