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.

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.
