Led Image

  • 3 mins read

An LED is a display-only control that shows the state of a device parameter. The LED control helps the designer to graphically show a certain condition, as defined by the designer, such as a warning. The “LED Image” control allows you to change the entire image of the LED where the “LED Color” control is a simplified control where you only need to change the color of the LED.

Controls can be managed in the Custom Panel designer and, once the Custom Panel is activated, utilized by the end user. This control must be linked to a parameter or system function to function properly. You can also easily add a pre-defined label.

For example, the designer wants to show when the pink noise levels on each of the four inputs of a DriveRack 4800 are more than 10dB. First, he adds an LED and links it to the pink noise on Channel 1.

The designer then goes into the Properties field to the Parameters Value and defines the value with the LED Values Editor.
