[Introduction]：E810-U41 is an industrial-grade USB to 4-way RS485 conversion module. With an external USB interface, 4 independent RS485 interfaces can be converted without affecting each other. It is suitable for scenarios where the computer is connected to multiple RS485 networks at the same time. Built-in RS485 automatic transceiver switching circuit, independent pin control switching, makes RS485 communication more reliable, and can connect more devices at the same time.
