## Long description

UGREEN USB-A to RS-232 Serial Cable UGR333, 1.5 m, Gray provides a direct wired connection between a computer with a USB-A port and devices that use an RS-232 serial interface. The 1.5 m cable integrates a USB-to-serial bridge to enable data transfer, device configuration and communication with legacy equipment without requiring an internal serial port. The cable's neutral gray jacket and compact inline converter make it suitable for desktop and industrial environments where a reliable, plug-and-play serial link is needed.
Advantages
The cable eliminates the need for PCI/PCIe serial cards or external adapters by offering a single-cable solution that converts USB-A to RS-232. It supports common serial control and data protocols through a stable wired connection, reducing latency and interference compared with wireless alternatives. Its 1.5 m length balances reach and cable management, while the integrated converter simplifies installation and minimizes additional components.
Suitable for
 Connecting PCs or laptops with USB-A ports to modems and serial modems
 Programming and configuring industrial controllers, PLCs and automation equipment
 Integrating POS terminals, receipt printers and barcode scanners that use RS-232
 Linking serial peripherals such as measurement instruments, sensors and legacy hardware
Key specifications
 Cable type: USB-A to RS-232 serial cable with integrated USB-to-serial converter
 Length: 1.5 m
 Color: Gray
 Connector (host): USB Type A (male)
 Connector (device): DB9-style RS-232 (male or female as applicable to device connection)
 Data interface: RS-232 serial communication protocol support
 Power: bus-powered from USB port (no external power supply required for typical serial link functions)
How to use
Install any required drivers for the operating system if prompted; many systems detect the USB-to-serial converter automatically and assign a virtual COM port. Connect the USB-A end to an available USB port on the computer and attach the RS-232 end to the serial device, ensuring correct orientation and secure connection. Configure the communication parameters in your terminal software or device utility (baud rate, data bits, parity, stop bits and flow control) to match the serial device settings, then initiate data transfer or configuration commands.
Usage recommendations
Use a direct USB port on the computer rather than an unpowered hub for best stability. Verify COM port assignment in the operating system before launching terminal applications. For industrial or noisy electrical environments, keep the cable away from high-voltage lines and use shielded routing where possible. Check device documentation for required RS-232 signal levels and flow control settings to avoid communication errors.
