Communication via standard connection (RS232/RS485)
Use the following parameters to configure the instrument for communication via the 8-pin M12 connection:
If the 9-pin D-sub (side) connector of the instrument is configured for RS485 communication (FLOW-BUS/Modbus), it will
not respond when connected to an RS232 configuration. In that case, use the power-up functionality of the
to switch to configuration mode and enable RS232 communication.
After configuring the required parameters, remember to return the instrument to the original communication mode.
