Tip: The information in parentheses following each ID number
indicates whether the number has been assigned to any sensor or
actuator. If it has been assigned to a sensor or actuator, it shows its
serial number. Otherwise, it shows the word "unused."
The manual assignment method is unavailable if you selected
multiple sensors or actuators in Step 2.
5. Click OK. The EMX starts to display the managed sensor or
actuator's reading and state.
6. To manage additional ones, repeat Steps 2 to 5.
Note: When the total number of managed sensors and actuators reaches
the maximum, you CANNOT manage additional sensors or actuators
unless you remove or replace any managed ones. To remove a sensor
or actuator, see
Unmanaging Environmental Sensors or Actuators
(on page 256).
Special note for a Raritan humidity sensor:
As of release 3.1.0, a Raritan humidity sensor is able to provide two
measurements in the user interface - relative and absolute humidity
values.
 A relative humidity value is measured in percentage (%).
 An absolute humidity value is measured in grams per cubic meter
(g/m
3
).
Note: Prior to release 3.1.0, only relative humidity values are available.
Relative humidity sensors can be "automatically" managed but absolute
humidity sensors CANNOT. You must "manually" manage absolute
humidity sensors if absolute humidity measurements are required.
Relative and absolute humidity values of the same humidity sensor share
the same serial number and port position as illustrated below.
However, relative and absolute values of the same humidity sensor DO
NOT share the same ID number. The above diagram shows that the two
values have different ID numbers -- one is 4 and the other is 5.
