USB to RS485 adapter for serial communication

Check driver support and wiring before use

Verify that your operating system provides a CH340C driver or that one can be installed from the chip vendor. Confirm the target device uses RS485 signalling and matching baud-rate settings, and prepare the correct twisted-pair cabling with proper termination resistors.
