You can combine the use of sensors connected to the LabPro with output from the Digital Control Unit (DCU). Examples include alarm systems, temperature-controlled environments, and smart robots.
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 have the auto-ID feature and may need to be set up manually
Setting up the Digital Out Feature
Click the Turn
ON When box to activate the digital out feature. Select a column from the pop up menu to control the action of the DCU. In the following example, temperature readings will control the digital out lines. ![]() Click the Greater Than radio button to cause the digital lines to be turned ON when the sampled value is larger than the entered value. Click Less Than to turn the lines on when the sampled value is less than the entered value. In this example, line 1 will be ON when the temperate is greater than (or equal to) 10 degrees Celsius, and OFF otherwise. You can also have the digital lines turned on when a parameter (variable) is met. |
You can select a limited combination of digital lines to turn
on. Only
16 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.![]() Digital lines will only be controlled during Real Time data collection, not during very fast collection. |

Control Unit (DCU) Manual that comes with the unit. The manual can
