USB 2.0 to RS232 DB9 adapter

This adapter connects legacy serial equipment such as modems, barcode scanners, label writers and industrial controllers to a modern USB port. It uses the FTDI FT232RL chipset for broad driver support across Windows, Mac and Linux systems. The six-foot cable length suits bench testing and fixed installations alike. No external power supply is required.

Sustained 1Mbps transfer with triple shielding

The tinned copper conductors and triple shielding maintain a steady 1Mbps data rate during long logging or configuration sessions. USB bus power keeps the link stable without a separate adapter. Driver installation is a one-time step; afterwards the device enumerates as a standard COM port for any terminal or custom software.

Replaces built-in serial ports and PCI cards

It upgrades machines that lack a native DB9 port or where an add-in card is impractical. The jump is worthwhile when you need a reliable, driver-mature bridge for RS-232 gear without opening the case. Buyers who require galvanic isolation or data rates above 1Mbps will need a different class of converter.

Questions about this item

Does the FTDI FT232RL chipset draw noticeable power or generate heat when the cable runs all day?

The adapter is powered by the USB port and uses a low-power FTDI FT232RL chipset, so it adds minimal load and stays cool during continuous use.

What must I already have on my computer for this USB Type A to DB9 cable to work?

You need a free USB Type A port and a supported OS — Windows 10, 8.1, 8, 7, XP, 2000, Linux or Mac OS X 10.6 and above — plus the one-time driver install.

Will the 1 Mbps transfer rate and DB9 connector work with my legacy 9-pin serial equipment?

Yes, the cable provides a standard 9-pin DB9 RS-232 interface at up to 1 Mbps, matching the pinout and speed expectations of older serial modems, scanners, routers and industrial gear.
