USB-to-RS232 adapter for legacy serial devices

This BONAEVER cable adds a DB9 female COM port to any computer with a USB 2.0 socket. It uses an FTDI FT232 chipset and a nine-wire pinout covering DCD, RXD, TXD, DTR, GND, DSR, RTS, CTS and RI. Driver support spans Windows 11, 10, 8, 7, Mac OS 8 and later, and Linux 2.4.0 and later. The three-foot length gives modest reach without excess slack.

Sustained communication through FTDI silicon

The FT232 processor handles continuous data streams without the drop-outs common in cheaper bridge chips. USB-powered operation removes the need for an external supply, so the link stays alive as long as the host port delivers current. Signal levels remain stable over the full cable run because the DB9 connector follows the standard RS232 pin assignment. No active cooling or throttling management is required.

FTDI FT232 chipset decides compatibility

Genuine FTDI silicon is the single factor that determines whether legacy instruments, PLCs or industrial consoles will enumerate reliably across every supported OS. Clones often fail driver binding on newer Windows releases or Mac updates. If your workflow depends on uninterrupted serial sessions, this chipset is the specification that validates the purchase.

Questions about this item

How much power does the FTDI chipset draw when the adapter runs all day?

The adapter is USB-powered and draws its operating current directly from the host USB 2.0 port without needing an external supply.

What operating system must my computer run for this DB9 cable to work?

It supports Windows 11, 10, 8, 7, Mac OS 8 or higher, and Linux kernel 2.4.0 or later.

Will this 3 ft cable connect my legacy 9-pin serial device to a modern laptop without a COM port?

Yes, the USB-A male to DB9 female converter adds a standard RS232 serial port so older equipment can communicate over USB.
