Frequently Asked Questions
Do I need a driver for this converter?
The converter uses standard USB-to-serial chipset drivers supported on Windows, Linux and macOS. Windows may auto-install; Linux/macOS often recognize it as a COM/tty device without additional software.
How do I enable or disable line termination?
Each RS485 channel has a DIP switch to toggle its built-in 120 Ω terminator. Slide the switch to “ON” to enable termination when the converter is at the end of a bus segment.
How does the surge protection work?
Onboard TVS diodes clamp high-voltage spikes, while resettable fuses and protection diodes guard against over-current and reverse-polarity events, ensuring stable RS485 signal integrity.
