The HT403I-R3 Serial to Fiber Optic Converter is a versatile fiber optic MODEM that supports simultaneous RS-232, RS-485 and RS-422 communication interfaces and is perfect for connecting a remote terminal unit (RTU) to a host computer (HOST) or a distributed data acquisition system (SCADA) controller.The HT403I-R3 The HT403I-R3 supports RS-232, RS-485 and RS-422 asynchronous communication protocols and can mix two RS-232, RS-485 or RS-422 interfaces at the same time, supporting 2-wire (half-duplex) RS-485 and 4-wire (full-duplex) RS-422 operation.The HT403I-R3 is equipped with a multi-interface that can support RS-232 or RS-422/ The HT403I-R3 converter can extend the transmission distance to 2km (using multimode fibre) or 120 km (using singlemode fibre).
The HT403I-R3 serial to fibre converter supports point-to-point or point-to-multipoint interconnections for the transmission and conversion of full/half duplex signals and their equivalents in a fibre optic environment. Optical fibre is the ideal solution for applications where the transmission media must be protected from electrical interference, lightning, atmospheric or chemical corrosion.
The HT403I-R3 is widely used in a variety of industrial control, process control, traffic control and intelligent communities, and is particularly suitable for banks, electric power and departments and systems that have special requirements for electromagnetic interference environments.
