Communication via the power supply connection(RS232/RS485)
Use the following parameters to configure the instrument for communication via the 9-pin D-sub (power) connection:
· If the 9-pin D-sub connector is set for RS485 communication, the instrument will not respond when connected to an
RS232 configuration. In that case, use the power-up functionality of the multifunctional switch to enter configuration
mode and enable RS232 communication.
· After configuring the required parameters, use the same procedure to leave configuration mode and restore the original
communication settings (otherwise, configuration mode remains enabled after power down).

4.8 Fluid set
For changing fluid, flow range or operating conditions, using the FlowTune software is strongly advised. FlowTune checks
any changes for compatibility of the process conditions with the instrument. When the parameters described in this section
are changed manually, no such checks are performed, and the instrument output may become disordered or the
instrument may even get damaged if used in conditions the instrument is not suited for. When in doubt, consult your
Bronkhorst representative.
