Using Numeric Feedbacks

Numeric feedbacks are used for information that can be represented as a number. An example of a numeric feedback is volume level.
This solution describes how to use a numeric feedback in a project and how to customize it. The example uses Kramer’s VP-773AMP Presentation Switcher.

  1. Drag the Feedback onto a Page
  • To use the volume feedback, drag it to your page.


    Note that the numeric feedback dragged to the page is a placeholder. Real data cannot be displayed until the GUI receives feedback from the actual device.
  1. Numeric Feedback Properties
  • Click on the feedback object on the page to open its properties.

Name: Give the feedback a name.
Row: Vertical position of the feedback.
Column: Horizontal position of the feedback.
Width: Horizontal size of the feedback (number of grid spaces).
Height: Vertical Size of the feedback (number of grid spaces).
Execute Macro On: If the feedback contains a macro, does the macro execute when the value of the feedback changes or every time the value is updated?
Display Option: Display the feedback as a number, a bar, or both (default) (see illustration below).
Font: Font used for your feedback.
Font Size: Size of the text.
Font Bold: Yes to bold the text.
Text Color: Color of the text.
Text Alignment: Horizontal position of the text.
Display options:
Number: The feedback displays only the number value received.

Bar: The feedback displays only a status bar.

Both: The feedback displays both the number and the bar.

  1. Feedback Bar Settings
    When using the bar, minimum and maximum values must be defined.
  • To find this setting, click on the final level of the feedback, in this example ‘Value’.
  • View the properties of this item.

    Usually these values are already set based on the full range of responses for this specific device. If you need to change these values, change them accordingly. (Note: changing the values does not limit the volume range, it simply defines the range for the bar).
  1. Feedback Number Settings
    When using the number, units can be assigned to the number.
  • To find this setting, click on the final level of the feedback, in this example, ‘Value’.
  • View the properties of this item.
  • Click the drop-down to see the units. Choose whatever fits the feedback.
  1. Querying
    The feedback now operates. When the volume up or volume down button is pressed, the feedback is received. However, when the panel is loaded for the first time, the feedback is blank until a volume button is pressed.
  • To fix this, create an entrance that ‘asks’ the VP-773AMP its volume level when the page is loaded.
