E810-U41C USB to RS485 serial port to RS232 converter Industrial grade TTL conversion module communication adapter photoelectric isolation RS422 high protection protection industrial lightning protection 3M high speed
[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. 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.
