Industrial USB to Serial Adapter

The Tripp Lite U209-30N-IND connects RS422 and RS485 equipment to a USB 2.0 Type-A port using an FTDI chipset and a DB9 male connector. It targets engineers and technicians who need reliable serial links for printers, scanners, surveillance cameras or card readers on Windows, Mac or Linux systems.

USB Powered with EMI Shielding

The adapter draws power directly from the USB bus, removing the need for an external supply. Double shielding protects the 230 Kbps data stream against EMI and RFI line noise, while the FTDI driver automatically reassigns COM port values to prevent configuration conflicts.

Compact 30-Inch Cable for Tight Spaces

A 2.50 ft black cable with nickel-plated connectors weighs 2.12 oz and includes a DB9 to terminal block adapter for flexible wiring. The short length suits panel-mount or bench-top installs where long runs are impractical, though buyers needing extended reach or multiple ports will require a different solution.

Questions about this item

How do I install the Tripp Lite U209-30N-IND USB to RS485/RS422 adapter, and what step is often missed?

Plug the Type A USB 2.0 connector into the computer, connect the DB9 male end to the RS422 or RS485 device, then install the FTDI driver from the included CD before the operating system assigns a COM port.

What maintenance or replacement will the Tripp Lite U209-30N-IND adapter need over time?

The adapter has no moving parts or batteries; only the nickel-plated DB9 contacts and gold-plated USB contacts may eventually require cleaning if signal quality drops after years of mating cycles.

What limit appears first when the Tripp Lite U209-30N-IND adapter runs under sustained load?

The FTDI chip caps throughput at 230 Kbps, so continuous high-volume traffic will hit that bandwidth ceiling before the double-shielded cable or USB power delivery becomes a constraint.
