DASH4PROFDUserInterface / VariableTree

Variable tree


The Variable Tree is displayed along the right hand side of the main display screen.


It is a list of variables that can be assigned to the controls. All of the variables can be categorized into seventeen major groups.

  1. Common
  2. Maths channels
  3. Voltage
  4. Digital
  5. GPS
  6. Attitude
  7. General use
  8. Time
  9. Angle
  10. Pressure
  11. Temperature
  12. Auxiliary
  13. Miscellaneous
  14. Triggered test
  15. Lap timing
  16. ADAS test
  17. CAN


Assigning variables to controls

There are two ways to associate a variable with a control - i.e. have the control display that variable

  1. Drag the variable from the tree and drop it onto the body of the control.
  2. Use the "Variable" drop down list in the property page of the control


Variable Properties

Each and every variable has a set of properties. To make alterations to the variables, click on the property that you wish to edit. This will open up a window that is specific to the property that you wish to alter.

The list of properties is as follows:

Advanced options

  • Maximum rate of change
The Maximum rate of change option will allow you to set a value which limits how much the variable can change over one second. This can be disabled by setting the value to zero.

Sensor type / Units

  • Standard
You can select a standard transformation relevant to the selected variable from a drop down list.
  • Custom
You can write an equation that will be used to by the DASH4PRO to convert the native values received from the data logger into the value that is shown on the DASH4PRO display.

The independent variable x is used to refer to the present variable.

e.g. If you wish to convert a voltage value to millivolts, you can write the following equation.


Variable Name

This is the name assigned to the variable. Name of any variable can be changed to suit with your requirements.


Smoothed over

This is a smoothing filter that is used to smooth out any peaks and troughs in the data. Smoothing can be disabled by setting this value to zero.


Low alarm f the value of the given variable goes below the low alram value, the low alarm will be triggered on the DASH4PRO and the user will be notified.


High alarm

If the value of the given variable becomes grater the high alarm value, the high alarm will be triggered on the DASH4PRO and the user will be notified.

Note: If both the low and high alarm values are set to zero, alarms are disabled for this variable.
