Identifying Sensor or Actuator Channels
A sensor package may have multiple contact closure (CC) or dry contact
(DC) channels, such as DX-D2C6 or DX-PD2C5.
When the PX initially detects and automatically manages a sensor
package with multiple channels, all channels are assigned with ID
numbers in sequence.
If you manually manage these channels by selecting "Automatically
assign a sensor number," the PX assigns ID numbers randomly because
this option assumes that users do not care about the sequence. In this
case, see the Channel column to identify each channel correctly. For
example, CC1 or DC1 is Channel 1, CC2 or DC2 is Channel 2, and so
on.
Managing Environmental Sensors or Actuators
The PX 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 PX device can manage a maximum of 32 environmental sensors or
actuators.
When there are less than 32 managed sensors or actuators, the PX
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 294).
To manually manage an environmental sensor or actuator:
1. Click Peripheral Devices in the Explorer pane, and the Peripheral
Devices page opens in the right pane.
