Dymec 5843 and 5844 Link/Repeaters may op- tically connect devices of different formats, eliminat- ing the need for format converters. For example, an RS232 IED may be connected to a model 5844 which is optically connected to a model 5846, which, in turn, can communicate electrically to its IED in EIA 485.
