USB-C to RS-485/422 industrial converter

The UOTEK UT-890-TC is a USB Type-C to RS-485/422 converter built to industrial-grade specifications. It uses an FTDI chipset for broad driver compatibility and stable communication. The 1.5 metre cable connects a USB-C host to a DB9 male connector carrying RS-485 or RS-422 signals. It suits engineers integrating modems, barcode scanners, tax-control units, CNC equipment or other RS-485/422 devices.

Plug-and-play with status LED and auto direction

Driver installation follows standard FTDI procedures on Windows, Linux and macOS; the converter then appears as a virtual COM port. An LED on the serial end shows link status and traffic, helping diagnose wiring faults quickly. The adapter automatically detects and controls data-flow direction for both 2-wire half-duplex and 4-wire full-duplex modes, so no manual jumper or software setting is required. The 1.5 metre USB length respects the 5 metre USB limit; the RS-485/422 side reaches up to 200 metres at 9600 bps.

For industrial integrators needing rugged USB-C

This converter fits builders who need a USB-C native connection to legacy RS-485/422 gear in harsh environments, with operating temperatures from -40 to 85 °C and 600 W surge plus ±15 kV ESD protection. It supports up to 32 nodes on a multi-drop bus at baud rates from 300 to 921 600 bps. Buyers who require galvanic isolation, a terminal-block connector instead of DB9, or a longer USB pigtail should look at alternative models.

Questions about this item

How can I confirm the UT-890-TC is communicating correctly after connecting it?

The serial-port end has an indicator light; a steady or flashing light shows normal RS-485/422 data flow, while no light suggests a wiring or driver issue.

What comes in the package and what must I provide myself?

The box contains one UT-890-TC converter with USB-C male and DB-9 male connectors on a 1.5 m cable; you must supply the twisted-pair or shielded wire for the RS-485/422 field side.

Which serial standard should I select — RS-485 or RS-422 — for my device?

The converter supports both; choose RS-485 for 2-wire half-duplex or 4-wire full-duplex networks up to 32 nodes, or RS-422 for 4-wire full-duplex point-to-point links, matching your equipment's interface.
