7.10.1 Setting the devices connected to the RS485 BUS
1. Assign an address to each device. The address identifies the device distinctly on the RS485 BUS. When assigning
addresses to repeaters, use the DIP switch

). For the description of the addressing
procedure of SmartLevel and SmartLine-EXT stations, refer to the respective programming manuals.
Attention:
All other DIP switch configurations are NOT allowed.
2. Ensure that the EOL jumper (paragraph

) is in the EOL position (End Of Line) on the last repeater
or power station on the line but not on other devices.
