3. MOLA TCF 142 S TCF 142 M RS 232 422 485 to Fiber Converter User s Manual Second Edition December 2003 1 Overview Introduction The TCF 142 series converter is equipped with a multiple interface circuit that can handle RS 232 or RS 422 485 serial interfaces and multi mode or single mode fiber TCF 142 converters are used to extend serial transmission distance up to 2 km TCF 142 M multi mode fiber or up to 20 km TCF 142 S single mode fiber RS 232 or RS 422 485 interfaces can t be used to convert to Fiber on the same TCF 142 at the same time Why convert serial to Fiber Fiber communication not only extends the communication distance but also provides many good features as follows IMMUNE 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 electric currents for the communication path SECURITY Cannot be tapped by conventional electric means and is very difficult to tap onto optically Furthermore radio and satellite communication signals can easily be captured 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 circuits power surges or static electricity Reverse Power Protection The R
