MOXN TCF 142 M T TCF 142 S T RS 232 422 485 to Fiber Converter Quick Installation Guide Eighth Edition July 2006 1 Overview Introduction The TCF 142 series Ver 3 1 or later converters are equipped with a multiple interface circuit that can handle RS 232 or RS 422 485 serial interfaces and multi mode or single mode fiber The TCF 142 converters extend serial transmission distance up to 5 km TCF 142 M with multi mode fiber or up to 40 km TCF 142 S with single mode fiber The TCF 142 must be configured to transmit a particular serial interface e g RS 232 and RS 485 signals cannot be transmitted at the same time Why convert serial to Fiber Fiber communication not only extends the communication distance but also provides many advantageous features IMMUNITY FROM ELECTRICAL INTERFERENCE Fiber is not affected by electromagnetic interference or radio frequency interference It provides a clean communication path and is immune to cross talk INSULATION Optical fiber is an insulator the glass fiber eliminates the need for using electric currents as the communication medium SECURITY Fiber cannot be tapped by conventional electric means and is very difficult to tap into optically Furthermore radio and satellite communication signals can be captured easily for decoding RELIABILITY amp MAINTENANCE Fiber is immune to adverse temperature and moisture conditions does not corrode or lose its signal and is not affected by short
