描述

This FTDI chipset USB to RS232 DB9 converter cable is designed to add a native RS232 serial COM port to modern laptops and desktops that lack legacy serial interfaces. It is widely used in industrial automation, network engineering, commercial retail and IoT scenarios for connecting PLCs, industrial controllers, network switches & routers, POS terminals, barcode scanners, serial printers, CNC machines and legacy serial peripherals.

Built with genuine FTDI FT232R high-performance chipset, it provides ultra-stable serial communication with support for baud rates from 300bps up to 921.6Kbps, full parity modes and hardware flow control (RTS/CTS). The integrated 128-byte RX / 256-byte TX FIFO buffers effectively reduce CPU load and ensure smooth data transmission even under continuous high-load operation. It features COM port retention technology — the assigned COM number remains unchanged after reconnection or system reboot, eliminating repeated configuration for industrial software.

The DB9 male connector adopts gold-plated contact pins for oxidation resistance and reliable connection, with built-in Level-4 ESD protection (15kV air / 8kV contact) to safeguard connected equipment from electrostatic damage. The cable uses tinned copper conductors with foil shielding to suppress EMI/RFI interference, maintaining signal integrity in noisy industrial environments. The molded strain relief structure enhances bending resistance and extends service life for frequent plugging and on-site use.

It is fully compatible with Windows 7/8/10/11, Windows Server, macOS, Linux and Android systems, with drivers automatically installed on most mainstream operating systems. Standard cable lengths of 1m, 1.5m and 3m are available from stock. We support custom cable length, housing color, logo printing and private-label packaging for bulk OEM & ODM orders, making it an ideal choice for industrial distributors, system integrators and automation equipment suppliers.

常见问题解答

Q: What chipset does this USB to RS232 cable use?

A: It uses a genuine FTDI FT232R chipset, which is widely recognized in the industrial field for its excellent stability, long-term driver support and broad system compatibility.

Q: Which operating systems does this converter cable support?

A: It is fully compatible with Windows 7/8/10/11, Windows Server series, macOS, Linux and Android systems. Drivers are automatically installed on most mainstream systems, plug and play.

Q: What is the maximum baud rate supported?

A: It supports baud rates from 300bps up to 921.6Kbps, covering all common baud rates for industrial and commercial serial devices.

Q: What is COM port retention?

A: COM port retention means the cable will be assigned the same COM port number each time it is reconnected or after system reboot, avoiding repeated configuration of serial port parameters in industrial control software.

Q: Can this cable be used for PLC programming and network switch debugging?

A: Yes, it supports standard RS232 serial communication and hardware flow control, and is widely used for PLC programming, industrial controller debugging, and configuration of network switches and routers.

Q: Do I need to install a driver manually?

A: Most modern operating systems (Windows 10+, macOS 10.15+, mainstream Linux distributions) will automatically install the driver. For older systems, you can download the official driver from the FTDI website.

Q: Do you accept custom length and OEM service?

A: Yes, custom cable length, housing color, logo printing and private-label packaging are all supported for bulk OEM orders.
