E810-U41S Non-isolated 1-channel USB to 4-channel RS485 data conversion module

[Introduction]:E810-U41S is an industrial-grade USB to 4-way RS485 conversion module. With one external USB interface, you can convert 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. Built-in RS485 automatic transceiver switching circuit, independent pin control switching, making RS485 communication more reliable. The module is a universal USB-RS485 interface converter that can convert single-ended USB signals into RS-485 signals without external power supply.
