USB to Isolated RS485 Adapter

This FTDI-based adapter converts a USB port into an isolated RS485 serial interface for industrial and automation use. The dongle format allows direct connection to equipment without extra cabling. It suits engineers and technicians who need reliable serial communication over long cable runs.

Check USB port availability and RS485 wiring

Verify that your host has a free USB-A port for the dongle. Confirm the target device uses RS485 signalling and that the wiring matches the adapter pinout. Ensure your software can address the virtual COM port created by the FTDI driver. Isolation protects the host but does not replace proper grounding on the RS485 bus.
