Note
End Of Line (EOL) termination
The flowmeter EOL termination DIP switch is default set to EOL active. To change termination
setting see Setting the EOL termination DIP switches (Page 44). 5.4.3 Setting the EOL termination DIP switches
It is important to terminate the Modbus RS 485 line correctly at the start and end of the bus
segment since impedance mismatch results in reflections on the line which can cause faulty
communication transmission.
If the device is at the end of the bus segment, it is recommended to terminate the device as
shown in System configurations (Page 45). The table below shows the relation between the
DIP switch settings and the permissible communication interface set-ups. Default
configuration is EOL active. EOL termination DIP switches - DIP-переключатели с терминацией конца строки (EOL) ?????????
