[Introduction]：E810-U41C is an industrial-grade USB to 4-way RS485 conversion module. With one external USB interface, it can convert to 4 independent RS485 interfaces without affecting each other.The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. It is suitable for scenarios where the computer is connected to multiple RS485 networks at the same time.
