You can choose whether to monitor via NMOS or Ember+ on a Embrionix ST2110 Stick by navigating into its IP address on a web browser.
Once in the unit's webpage, you are prompted with the below table which will show you the available software loaded into the unit.
If the software description has an 'E+', it is the Ember+ control version.
The Element highlighted in green shows the currently active firmware. For example, in the above table the currently active software is the NMOS version.
To select the desired software, set the preferred element as default.
Please note, If you are unable to see the 'Set as default' button on the preferred element, this means the unit is already been calibrated to do so. In this case you will need to reboot you PAM unit to be able to control using your chosen protocol.
