The product supports data conversion between serial terminals and fiber, that enables bidirectional transparent data transmission between RS-232/485/422 serial ports and fiber network interfaces, allowing serial devices to have long distance transmission capabilities via multi mode or single mode fiber,up to 120km. It integrates protocols such as ARP, IP, TCP, HTTP, ICMP, UDP. All programs provide both Chinese and English interfaces, with a setup wizard for easy operation. Widely used in industrial control, equipment automation, IoT, environmental monitoring, intelligent transportation, and motion and environment monitoring.
