USB RS232/485 converter with FT232RNL

This adapter connects USB hosts to legacy serial equipment using an original FT232RNL chip for stable and compatible communication. It suits engineers, makers and technicians who need reliable RS232 or RS485 links for industrial gear, PLCs or development boards. The rugged ABS case makes it portable for field work and bench testing alike.

Switchable RS232 or RS485 with 120R termination

A hardware toggle selects between RS232 and RS485 modes while a second switch engages the onboard 120R resistor for RS485 bus termination. Built-in TVS diodes, a resettable fuse and ESD protection guard against surges, overcurrent and static discharge. Three LEDs show power, TX and RX activity so you can verify traffic at a glance.

Replaces bare USB-UART dongles and PCI serial cards

It upgrades from unprotected USB-to-TTL cables that lack isolation and from internal cards that need a free slot and driver hassles. The jump is worth it when you need both RS232 and RS485 on one tool, surge-safe operation on long cable runs, or driver support across Windows 7 through 11, Linux, macOS and Android without extra configuration.

Perguntas sobre este artigo

Which communication standard should I select, RS232 or RS485?

Toggle the onboard switch to choose RS232 for point-to-point links or RS485 for multi-drop networks; the same adapter handles both.

What does the FT232RNL chip deliver in daily use?

The original FT232RNL provides stable, high-speed USB-to-serial conversion with broad driver support across Windows 7 through 11, Mac, Linux and Android.

How does the 120R termination resistor affect the RS485 line?

Enable the resistor via the toggle switch when the adapter sits at the end of an RS485 bus to reduce signal reflections.
