FTDI FT232RL Chipset USB-to-Serial Adapter

This new USB 2.0 cable uses an FTDI FT232RL chipset to add a DB9 serial port to computers lacking native COM ports. It connects legacy serial devices such as modems, barcode scanners, label writers and industrial equipment through a standard USB Type-A interface. The 6 ft cable supports data rates up to 1 Mbps and draws power directly from the USB port. Driver installation is required once, after which the adapter works as a plug-and-play virtual COM port.

For Industrial and Legacy Equipment Integration

Engineers maintaining older machinery, network administrators configuring routers via console ports and hobbyists interfacing with microcontroller boards will find the FTDI driver stability valuable across Windows 10, 8.1, 7, XP, 2000, Mac OS X 10.6+ and Linux. Buyers who need a USB-C or USB 3.x host connector should look elsewhere because this cable terminates in a USB Type-A plug only. It is also unsuitable for applications requiring galvanic isolation or voltage levels beyond standard RS-232 signalling.

FTDI FT232RL Chipset Determines Driver Reliability

The FT232RL chipset is the single specification that decides whether this adapter will enumerate cleanly on modern operating systems without unsigned-driver warnings or sporadic disconnects. Generic alternatives often require manual driver binding or fail after OS updates, while FTDI's signed drivers install automatically on supported platforms. Triple shielding and tinned copper conductors (24/28 AWG) preserve signal integrity over the full cable length.

Questions about this item

What does the 1Mbps data rate mean when the cable is plugged into a real machine?

The FTDI FT232RL chipset delivers up to 1 Mbps over the USB 2.0 link, so legacy serial gear such as barcode scanners or industrial controllers can communicate at their full rated speed without a bottleneck.

Which serial standard does the DB9 connector implement and what does it limit in practice?

The 9-pin DB9 connector follows the RS-232 specification, cabling transmit, receive and ground lines so any device expecting a classic COM port works, but cable length and noise immunity are still bound by RS-232 electrical limits.

What physical clearance does the 6 ft cable need to fit between a PC and a rack-mounted device?

At 6 ft the cable spans roughly 2 metres end-to-end, with a standard USB Type-A plug on one side and a DB9 male connector on the other, so allow that reach plus a few centimetres for the connector bodies when routing through cable trays or behind equipment.
