Right-click the node in the Project Explorer window and select Properties. Select the Channels or Node tab.

To upload the serial number of a connected node to the Project Explorer window, right-click the gateway and select Refresh Node Serial Numbers.

Channels Tab: Analog Input

This dialog box includes the following components:

  • Channels—Specifies the channel or channels to configure.
  • Channel Configuration
    • Range—Specifies the voltage range of the selected channel(s):
      • -10 to 10 Volts
      • -5 to 5 Volts
      • -2 to 2 Volts
      • -0.5 to 0.5 Volts
  • Channel Attributes
    • Attribute—You cannot change this setting.
    • Value—You cannot change this setting

Channels Tab: Digital Input/Output

This dialog box includes the following components:

  • Channels—Specifies the channel or channels to configure.
  • Channel Configuration
    • Range—You cannot change this setting.
  • Channel Attributes:

AttributeValue
DIO Drive ModeSpecifies the channel state:

Tristate—The line is not driven.

Drive Low Only—When the DIO line is off, the output line drives low. When the DIO line is on, the output line tristates.

Drive High Only—When the DIO line is on, the output line drives high. When the DIO line is off, the output line tristates.

Drive High and Low—When the DIO line is on, the output line drives high. When the DIO line is off, the output line drives low.

Node Tab: Analog Input and Digital Input/Output

This dialog box includes the following components:

  • Device Name—Specifies the name of the WSN node, which appears in the Project Explorer window. LabVIEW assigns a default name to the node based on the Hardware Configuration ID. You can use this field to give the node a descriptive name.
  • Device Type—Specifies the type of WSN node. You cannot change this value.
  • Hardware Configuration—Specifies the hardware configuration ID and the sample interval (seconds).
    • ID—Allows you to map a node in the property tree to a node of that ID on the gateway.
    • Sample Interval (Seconds)—Specifies how often the node samples all inputs, in seconds. For End Nodes, the nodes sleep during this interval.
    • Sensor Power—Specifies the sensor excitation delay time:
      • 0 ms before sampling—turns on the Sensor Power immediately when the analog acquisition starts.
      • 25 ms before sampling—turns on Sensor Power 25 ms before the analog acquisition starts.
      • 100 ms before sampling—turns on Sensor 100 ms before the analog acquisition starts.
      • 250 ms before sampling—turns on Sensor Power 250 ms before the analog acquisition starts.
      • Always On—turns on Sensor Power when the next analog acquisition starts and leaves it on indefinitely.
Note Note  Enabling Sensor Power diminishes battery life.
