Industrial USB to serial converter

The Tripp Lite U208-001-IND adapts a USB Type-B port to a single DB-9 male connector for RS-422 and RS-485 equipment. It suits engineers and technicians who must link legacy industrial gear such as modems, scanners or GPS units to modern PCs, Macs or Linux hosts without native serial ports.

Bundled cable jumpers and drivers

A 3 ft USB-A to USB-B cable, two 2-pin jumpers and a driver CD arrive in the box. The jumpers let you set the port mode before plugging in, while the CD supplies the FTDI driver that enables COM retention so the same port number returns after a reboot or disconnect.

Steel enclosure with wall mounting

The black steel housing measures .90 by 2.80 by 3.00 inches and weighs .30 lbs, providing 15 kV electrostatic discharge protection for harsh environments. Integrated mounting tabs allow fixed installation on panels or DIN rails, keeping the DB-9 connection secure in vibration-prone settings.

Questions about this item

Will the DB9 connector or FTDI chipset need periodic replacement?

The industrial-grade steel enclosure protects the DB9 port and FTDI chipset, and the 15 kV ESD rating helps prevent damage that would require replacement.

What limits continuous RS-485 data throughput?

The USB-B interface and FTDI chipset set the practical throughput ceiling for sustained RS-422 or RS-485 traffic.

How much heat or noise does the adapter produce during all-day operation?

The passively cooled steel case runs silently and stays cool under normal RS-422/485 loads.
