(Nowadays, the RS-485/422 interface is widely used in industrial control. The bus-mounted connection method is used, and the star connection is not supported. The devices supported by one bus are limited, and the transmission distance is only 1200 meters. The construction has brought great inconvenience, and we are looking forward to the birth of the RS-485/422 bus cutting concentrator. H-8485 is an 8-port opto-isolated RS-485/422 bus cut concentrator, which terminates the RS-485/422 bus.)
