Operating Instructions Scope of Application The RS485 / FO Signal Converter is used for optical connection of up to 31 units with a bus-enabled electric RS485 interface to an FO connection that leads, e.g., to a star coupler, thus allowing to establish an interference-immune connection between the field devices and the centralized operating unit.
Protocol transparency Data transmission by the RS485 / FO signal converter is protocol- transparent in both directions, thus allowing the use of the converter for all common protocols (e.g. IEC protocol, DIGSI etc.) from 9600 bauds up to 115 kbauds. Data transfer The RS485 interface, which may be connected as a bus, is a two wire half duplex interface i.e.

Description of the Functional Unit The housed signal converter is a hard-wired and tested functional unit. It is provided with a snap-on mounting device for a 35 mm DIN EN 50022 rail and with screw-type terminals for safe connection of the auxiliary power supply.
FO-Connections The receiving optical connectors are marked with R1/2, the transmitting connections with T1/2 (see Fig. 2). ATTENTION! Please tight the mechanical screw connections of the FO - cables with FSMA plug carefully and only by hand (do not use tools). The ST plugs are to be shifted with the lateral nose into the groove of the device connection and locked afterwards.

Installation and Commissioning Warning When operating electrical devices, certain parts are necessarily under dangerous voltage. Therefore, disregard of the operating notes may cause servere bodily injury or property damage. Installation and electrical connection of the device should be performed by adequately qualified personnel only.
5.2.1 Power supply X2 The wires for the auxilliary voltage are screwed on terminal X2 at he bottom side of the device. The assignment of the terminals is printed at the front side or can be read in this manual. Because the device has no ON/OFF switch this switch must be installed external if it´s necessary.
5.2.4 RS485-Bus connection X6 A shielded 2-core twisted-conductor cable is recommended. Connect one conductor to -X5/A (signal A) and one conductor to -X5/B (signal B) using screw-type terminals, or connect the standard bus cable e.g. 7XV5103 to the 9-pin subD socket. To guarantee a trouble-free use of the converter according to the specified characteristics, set the cable screen on one side of the cable to the earth potential.
Applications Optical line structure When adding RS485/fibre optic converters in serial a connection into an existing optical system with star couplers connected in radial structure, it is possible to connect a number of devices with RS485 interfaces. 12.10.2006 RS485-FO Converter 2-channel Page 25 of 28...
