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.

Questions about this item
Does the FTDI USB to Isolated RS485 adapter include the USB cable or must it be purchased separately?
The adapter is a self-contained dongle that plugs directly into a USB port, so no separate USB cable is required.
How do I choose between the different 485 interface versions for my application?
This model provides a single isolated RS485 interface via FTDI USB; select it when you need galvanic isolation for industrial serial networks.
