HT401-1Dd1E 1-port 100Mbps Ethernet + 1-port bidirectional RS-485 data transceiver, featuring an SC fiber optic interface with a single-mode transmission distance of up to 20 km. It includes 1 bidirectional RS-485 data interface for simultaneous point-to-multipoint data transmission, supporting 1 bidirectional half-duplex RS-485 data channel. It features adaptive single/multimode fiber with zero-latency automatic forwarding for asynchronous transmission. Converts RS-485 interfaces to fiber optics, primarily used in: RS-485 alarm systems, barrier gates, access control systems, remote video teaching systems, intelligent transportation, and other fields.
