USB to RS485 Converter with FT232RNL Chip

This industrial-grade USB to RS485 converter uses an original FT232RNL chip for stable bidirectional serial communication. It targets engineers and developers working on industrial control testing, equipment debugging and data acquisition projects. The isolated design adds protection for demanding wired environments.

Sustained Communication Stability and Range

Onboard isolation, TVS ESD protection, a resettable fuse and protection diodes help maintain signal integrity during long sessions. The adapter supports communication rates from 300bps to 512000bps and can reach about 1.2km transmission distance with suitable cabling. Status LEDs for power, TX and RX simplify monitoring.

Compatibility and Setup Checks

Verify that your host runs Windows 11, 10, 8.1, 8, 7, XP, Linux, Mac, Android or WinCE before ordering. Ensure your application uses RS485 wiring and that the 1.2km distance figure matches your cable quality and environment. Buyers needing non-isolated or shorter-range USB serial links should consider other options.

Questions about this item

Does the converter draw enough power from the USB port to run all day without an external supply?

The board is USB-powered and includes a resettable fuse and protection diodes, so it draws its operating current from the host port during continuous use.

What cable and driver must I already have to connect this adapter to a Windows 10 PC?

You need a standard USB-A cable and the FTDI virtual COM port driver installed on Windows 10 for the FT232RNL chip to appear as a serial port.

Can the RS485 side link directly to legacy equipment that only runs at 300bps?

Yes, the adapter supports communication rates from 300bps up to 512000bps, so it can talk to older devices fixed at the lower speed.
