B+B SmartWorx Serial to Single-mode Fiber Optic Converters

Advantech B+B SmartWorx' ILinx™ fiber converters are designed with functionality required for heavier industrial environments. Model FOSTCDRi-Sx industrial-grade isolated converter changes RS-232, RS-422 or RS-485 to singlemode fiber optics.

FOSTCDRi-Sx extends serial data ranges up to 15 km (9 mi) and provides the most versatile connection possible between asynchronous full or half-duplex serial equipment. In addition to direct point-to-point connectivity, it is capable operating in a multi-drop mode. This allows one serial device to communicate with up to 31 others around a fiber optic ring. Since it supports mixed serial standards, it can replace other converters and isolators and add the EMI/RFI immunity inherent to fiber optic communications. Fiber optic connectors are SC or ST.

Automatic Send Data Control circuit controls the RS-422/485 driver chip, eliminating the requirement for special software. Easy to install and configure, it has a 12-position DIP switch to set up the RS-422/485 parameters and removable terminal blocks to connect serial signals and power. In RS-232 mode, it supports Transmit Data and Receive Data. Handshaking signals are not passed through.
