CH340 USB-to-RS485 Serial Converter
Connect a supported USB computer to an RS485 communication line. This CH340-based converter provides the interface for a correctly configured serial setup.
✅ Give a USB host an RS485 connection - The converter adds a route to supported PLC or other RS485 equipment without an internal serial card.
Match the Serial Settings and Wiring
The computer needs the appropriate CH340 driver and software for the connected system. Match the communication settings and RS485 wiring with the device's documentation.
This is an interface converter, not a PLC or an automatic protocol translator. Disconnect equipment as required before wiring and use only a circuit within the converter's specification.
