    SubStation Hardened RS232 Serial Copper to Fiber Link/Repeaters

    For Reliable Substation Communications

    Dymec models 5843 and 5844 are hardened fiber optic Link/Repeaters that convert RS232 or TTL level single channelcopper to amplitude based fiber output. 5843 and 5844 Link/Repeaters support data rates from dc to 250k bps, DCE or DTE port configuration and a diagnostic/test mode that allows testing of the copper and fiber connections before the connected IED is active in the network.

    Dymec Links media converters are Class 1, Div 2 certified for use in hazardous locations in the US and Canada. The Class 1, Div 2 certification mark allows use of Dymec Links in ignitable environments requiring spark-free operation. This is a requirement for many customers, particularly those in petroleum and petrochemical applications, where hazardous ignitable environments abound.

    By simply setting a few switches, the Dymec 5843 and 5844 Link/Repeaters can be configured for point-to-point, star, optical bus, or loop networks, and permit quick, easy connection of devices. For example, an extensive multi-drop network -- where two or more intelligent electrical devices are connected and communicating -- can be constructed simply by connecting the devices through Link/Repeaters.

    5843 and 5844 Link/Repeaters may optically connect devices of different formats, eliminating 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 electrically in EIA 485.
