## Long description

UGREEN USB to DB9 (RS-232) Cable CR104 1.5 m in black provides a direct USB-to-serial connection for computers and devices that require an RS-232 interface. The cable converts a USB Type-A host port to a DB9 male connector, enabling communication with legacy serial equipment such as modems, industrial controllers, POS terminals and measurement instruments. With a 1.5 m length, the cable offers a balance between reach and cable management for desktop and bench setups.
Advantages
This USB to DB9 cable supports reliable data transfer and stable serial communication without the need to open device housing or replace existing serial hardware. It simplifies configuration and diagnostics by providing plug-and-play connectivity on systems with appropriate driver support. The cable's molded connectors and strain reliefs are designed to reduce wear from regular insertion and movement, and the black finish integrates unobtrusively into professional environments.
Suitable for
 Connecting modern laptops or desktops to RS-232 modems and serial printers
 Interfacing industrial controllers, PLCs and factory equipment for configuration and monitoring
 Linking POS terminals and barcode scanners that use DB9 serial ports
 Connecting measurement instruments and laboratory devices for data logging and diagnostics
Key specifications
 Cable function: USB to RS-232 (DB9) serial adapter
 Connector A: USB Type-A (male)
 Connector B: DB9 (male) serial connector
 Cable length: 1.5 m
 Color: black
 Typical use: data transfer, device configuration, diagnostics
How to use
Install any required drivers on the host computer according to the operating system instructions if automatic driver installation does not occur. Plug the USB Type-A end into an available USB port on the computer and connect the DB9 end to the serial device. Configure serial port parameters (baud rate, parity, data bits, stop bits, flow control) in the host application or system device manager to match the connected device. After configuration, use terminal software or the device's configuration utility to communicate, transfer data or perform diagnostics.
Usage recommendations
For stable operation, use a direct USB port on the computer rather than an unpowered hub, and confirm driver compatibility with your operating system. Keep the cable away from high-interference sources and secure connectors to avoid accidental disconnection during critical data transfers.
