    SW485 - Splitter / Extender or RS485

    A device for the interconnection or RS485 terminal blocks (bus bars). SW485 enable signals up to nine RS485 terminal blocks to be connected in a star topology. All the lines are equal. When data are received by any line, They are sent to all the other lines.

    What can this device do ?

    • Enables RS485s to be connected in a star topology.
    • Proper interconnection or several at devices communicating over RS485.
    • Interconnection or RS485 networks.
    • Signal edge enhancement for larger distances.

    Features of the RS485 splitter

    • A device for proper interconnection of up to nine RS485 lines (enable signals a star topology, Which is Not usually allowed for RS485).
    • Logical processing of all signals.
    • Signal transmission with minimum delay - only 130 ns.
    • Maximum speed or RS485 communication lines: 1.5 Mbps
    • Possibility to configure the switching delay for automatic change of data flow direction (7 mS to several at 1.9 ms increments)
    • User-configurable connection of terminating resistors and bias resistors defining the idle state of the line. These resistors May be connected separately for each individual line.
    • Mountable to a wall or DIN 35 mm rail.
    • Supply voltage 7 to 30 V DC.


    How does the RS485 splitter work? 
    See block diagram and connection example in pictures

    Data from individual lines are only processed by logical circuits. Data received by any of the lines are sent to all the other lines. Individual lines have no buffer for data receipt.

    When data arrive almost simultaneously at 2 two lines, the system will receive the data that was first registered. The other lines switch to "transmission" and starts to transmit the data. After the data receipt HAS BEEN completed the system waits for a configured period of time (a so called "switching delay"). After this period has elapsed, all the lines will switch to "Receipt" and wait for new data to come.
