UGREEN CR104 USB 2.0 to RS232 DB9 Serial Cable 1.5M

The UGREEN CR104 USB to serial cable lets you connect RS232 serial devices to a computer through a standard USB 2.0 port. If your PC or Mac has no COM port, this 1.5m cable adds one without any extra hardware.

It works with the serial equipment many workplaces still use, including routers, GPS units, barcode scanners, label printers, POS devices and serial modems. This UGREEN serial cable supports data transfer rates above 1Mbps, and the COM port and baud rate can be adjusted to suit your setup.

Key Features

• USB 2.0 Input to RS232 DB9 Output: Plug the USB end into your computer and the DB9 end into your serial device. Older equipment connects to a modern PC without a built-in serial port.
• PL2303 Chip: The PL2303 chip handles the USB-to-serial conversion, giving you a reliable COM port connection for everyday serial work.
• Over 1Mbps Data Transfer Rate: The faster rate suits data exchange with scanners, printers, modems and similar devices.
• Adjustable COM Port and Baud Rate: You can set these to match your equipment, so the cable fits different devices and software.
• 1.5m Cable Length: The extra length gives you room to place a PC and a serial device apart from each other without straining the connection.
• Simple Plug-In Setup: Connect the device to the cable and the cable to your PC or Mac, which saves setup time for technicians and office users.

Why Choose the UGREEN CR104 USB to Serial Cable

Most new laptops and desktops no longer include a DB9 serial port, but many routers, POS systems, label printers and industrial devices still need one. The UGREEN CR104 closes that gap with a single cable, so you can keep using reliable older equipment.

If you work with network gear, retail counters or data collection tools, this UGREEN USB cable gives you a dependable COM port when you need one. It supports a wide range of serial COM port devices, which makes it a practical addition to an IT toolkit or a shop counter.
