for 1 sec. The display shows the remaining time in seconds
and the green LED will be blinking. When the Auto setup procedure has finished the display goes back
to normal operation mode. If you want to cancel Auto setup press
Auto setup
again for one second.
To return the RS485 bus to the factory default setting (DustTool / DustLog connection) press the Auto
setup button within 6 seconds of the device booting up. Note that this will initiate a self-check
procedure during which the RS485 bus settings will be reset. When running outside of a production
environment, the check will fail due to lack of external testing hardware and issue an alarm. When
resetting the RS485 bus settings this way, make sure to reboot the device after the reset.
