Managing Environmental Sensors or Actuators
The EMX starts to retrieve an environmental sensor's reading and/or
state and records the state transitions after the environmental sensor is
managed. To control an actuator, you also need to have it managed.
The EMX device can manage a maximum of 32 environmental sensors
or actuators.
When there are less than 32 managed sensors or actuators, the EMX
automatically brings detected environmental sensors or actuators under
management by default. You have to manually manage a sensor or
actuator only when it is not under management.
Tip: You can disable the automatic management feature so that newly
connected environmental sensors or actuators are NOT brought under
management automatically. See
Disabling the Automatic
Management Function (on page 257).
To manually manage an environmental sensor or actuator:
1. Click Peripheral Devices in the left pane.
2. Select the checkbox of the desired sensor or actuator on the
Peripheral Devices page. To manage multiple ones, select multiple
checkboxes.
Note: To identify all detected sensors or actuators, see Identifying
Environmental Sensors and Actuators (on page 240).
3. Click Manage. If you selected only one sensor or actuator, the
"Manage peripheral device <serial number> (<sensor type>)" dialog
appears, where <serial number> is the sensor or actuator's serial
number and <sensor type> is its type.
Note: For a sensor package with contact closure (CC) or dry contact
(DC) channels, a channel number is added to the end of the <sensor
type>.
4. There are two ways to manage a sensor or actuator:
 To manage it by letting the EMX assign a number to it, select
"Automatically assign a sensor number." This method does not
release any managed sensors or actuators.
 To manage it by assigning the number you want to it, select
"Manually select a sensor number." Then click the drop-down
arrow to select a number.
If the number you selected was already assigned to a sensor or
actuator, that sensor or actuator becomes released after losing
this ID number.
