[Introduction]：E810-U41CS is an industrial-grade USB to 4-way RS485 conversion module.The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. With one external USB interface, it can convert to 4 independent RS485 interfaces without affecting each other. It is suitable for scenarios where the computer is connected to multiple RS485 networks at the same time. It has a built-in RS485 automatic transceiver switching circuit and independent pin control switching, making RS485 communication more reliable and allowing more devices to be connected at the same time.
