Chapter 6: Using the Web Interface257Disabling the Automatic Management FunctionThe factory default is to enable the automatic management feature forenvironmental sensors and actuators. Therefore, when the total numberof managed sensors and actuators has not reached 32 yet, the EMXautomatically brings newly-connected environmental sensors andactuators under management after detecting them.When this feature is disabled, the EMX no longer automatically managesany newly-detected environmental sensors and actuators, and thereforeneither ID numbers are assigned nor sensor readings or states areavailable for newly-added ones.To disable the automatic management feature:1. Click the EMX folder in the left pane.Note: The EMX folder's name can be customized. See Naming theEMX (on page 110).2. Click Setup in the Settings section. The setup dialog appears.3. Deselect the Peripheral Device Auto Management checkbox.4. Click OK.Controlling ActuatorsIf you have any DX sensor packages with actuators connected, whichcan move or control a mechanism or system, you can remotely turn on oroff the actuators to control the connected mechanism or system.To turn on or off an individual actuator:1. Expand the Peripheral Devices folder in the left pane to show a list ofenvironmental sensors and/or actuators.2. Click the desired actuator from the navigation tree. That actuator'spage opens in the right pane.3. Click "Switch on" to turn on the actuator, or "Switch off" to turn it off.To turn on or off multiple actuators:1. Click Peripheral Devices in the left pane.2. Select the checkboxes of the desired actuators on the PeripheralDevices page.Tip: An actuator is indicated with the icon displayed in the'Actuator' column.3.
