USB to RS232 Cable DB9 Female – FTDI Chip, 1Mbps, Plug-and-Play, 1.8m | DTECH DT-5002B

The USB to RS232 cable DB9 female converts a modern USB 2.0 port into a DB9 female RS232 serial interface, enabling any laptop or desktop PC without a built-in COM port to communicate directly with RS232-equipped industrial and commercial devices. The DTECH DT-5002B provides a DB9 female connector on the RS232 end — the correct gender to plug directly into the vast majority of RS232 serial equipment, which presents a male DB9 connector as standard. Powered by a genuine FTDI chipset supporting data transfer up to 1Mbps, plug-and-play on Windows 98 through Windows 11, USB bus-powered with no external supply needed, and supplied in a convenient 1.8m length, the DT-5002B is a clean and reliable serial converter for industrial, commercial and field applications.

USB to RS232 Cable DB9 Female — Why the Connector Gender Matters

RS232 serial connectors follow a consistent gender convention in industrial and commercial equipment. The overwhelming majority of RS232-equipped devices — PLCs, CNC controllers, barcode scanners, managed network switches, routers, modems, POS terminals, GPS receivers, weighing instruments and industrial sensors — present a male DB9 (DE-9M) connector on their serial port. To connect a PC or laptop directly to this equipment via USB, you need a serial converter with a DB9 female (DE-9F) end that mates directly. The DT-5002B provides exactly this, plugging cleanly into male DB9 serial ports with no gender-changer adaptors, barrel connectors or additional cables required. Eliminating extra connection points reduces contact resistance, removes potential failure points and simplifies installation on a workbench, rack or production floor.

For RS232 equipment with a female DB9 port — such as certain legacy PC serial ports, industrial terminals or extension cable runs — the DTECH DT-5011 USB to RS232 cable with male DB9 end is the correct choice. Both are available in the industrial serial product range at bam.ae.

FTDI Chipset — Driver Stability and Signal Reliability

The DT-5002B uses a genuine FTDI chipset, the most widely trusted USB-to-serial IC in professional engineering and industrial environments. FTDI provides manufacturer-signed drivers maintained continuously across all major Windows versions and Linux distributions, ensuring the adapter installs correctly and continues to function through operating system updates without manual driver intervention. Generic or counterfeit chipsets used in low-cost alternatives frequently fail driver validation on newer Windows versions, drop connections under load or trigger communication errors in industrial software that validates the chipset identity before accepting a connection. An FTDI-based USB to RS232 cable DB9 female avoids these failure modes, delivering reliable data transfer at rates up to 1Mbps across all standard RS232 serial communication speeds.

Virtual COM Port Setup and Application Compatibility

On first connection to a Windows PC, the FTDI driver — auto-installed by Windows Update on Windows 10/11 or manually installed from FTDI’s website for older versions — creates a virtual COM port visible in Device Manager under Ports (e.g., COM3, COM4). This virtual COM port behaves identically to a built-in hardware COM port. Any serial application can select and use it without modification: PLC programming software (GX Works, STEP 7, CX-Programmer, WPLSoft), terminal emulators (PuTTY, TeraTerm), CNC configuration tools and proprietary industrial control software all recognise it as a standard COM port. If the assigned number conflicts with existing software port assignments, Windows allows reassignment through Device Manager port properties with no hardware changes.

OS Compatibility, Power and Typical Applications

The DT-5002B supports USB remote wake-up and power management, drawing all power from the USB bus at 5V with no external supply. It is compatible with Windows 98/2000/ME/XP/Vista/7/8/10/11. Typical applications include PLC programming and configuration, CNC machine setup and diagnostics, managed network switch and router serial console access, barcode reader and POS terminal integration, GPS and measurement instrument data logging, firmware flashing for serial-interfaced embedded devices, and any RS232 serial communication from a modern laptop or PC that lacks a built-in COM port.
