How can I disable Loggernet from sending beacon frames?
Use the SetupScreen application from the LoggerNet Toolbar. Press the "Std View" button in the upper right ( if you are not already in the Standard View -- still in EZ View). Click on the PakBusPort object that is a parent to the datalogger(s) of interest. Now look in the Hardware tab, and you will see the "Beacon Interval" setting for that pakbus port. Proceed with caution.
Also a PakbusTcpServer object also has a Beacon Interval.
