Digital Out

You can combine the use of sensors connected to the LabPro with output from the Digital Control Unit (DCU). Examples include alarm systems and temperature-controlled environments.

This feature allows you to command DIG/SONIC 1 or DIG/SONIC 2 of LabPro to output a digital signal.

Setting up the Digital Control Unit

Note: Your Digital Control Unit may not be auto-ID and may need to be set up manually.

  1. Choose Set Up Sensors from the Experiment menu and select your interface.
  2. Click the Digital Control Unit and select Digital Out from the menu.
  3. Check the Turn ON When box to activate the digital out feature.
  4. Select a column to control the action of the DCU.
  5. Select Greater Than or Less Than. Select Greater Than to cause the digital lines to be turned ON when the sampled value is larger than the entered value. Select Less Than to turn the lines on when the sampled value is less than the entered value.
  6. Select the number of digital lines to turn on. Only certain combinations are possible because the LabPro has only four output lines per channel. The red LEDs on the DCU will be lit when their corresponding lines are on. You may wish to use the lines in pairs to allow you to switch the polarity applied to an electrical component.

Note: Digital lines will not be controlled during extremely fast data collection.

For complete details about the Digital Control Unit, consult the Digital Control Unit (DCU) Manual that comes with the unit. The manual can also be downloaded from the Vernier web site www.vernier.com.
