Communication via power supply connection (RS232/RS485)
Use the following parameters to configure the instrument for communication via the 9-pin D-sub connector on the side of
the instrument:
·
If the 9-pin D-sub connector is set for RS-485 communication, the instrument will not respond when connected to an
RS-232 configuration. In that case, use the power-up functionality of the
mode and enable RS-232 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).
