The Virtual Device – an Application Example

The number of buttons on the Virtual Device and their functionalities are defined using the

K-Config software in K-Config Virtual Device triggers layer.

Pressing a "button" on a Virtual Device application will send a corresponding command to the

Master RC.

In the following example, the Virtual Device has K-NET ID = 11 and pressing the first button (#1

in the defined K-Config Virtual Device trigger layer) of the Virtual Device executes the following

actions:

• The button color changes to red

• The text label (a defined text field) changes to PC SELECTED

• The SV-552 switches to the VGA input

The command sent from the virtual device is:

#BTN 1,11,R\r // Sent command from Virtual Device application

The answer from the Master RC to this event, as defined for Button 1 of the Virtual Device with

K-NET ID=11 in K-Config, is:

#11@RGB 1,255,0,0,1 // Set RED Color on Virtual Device

#11@LABEL 1,"ON" // Set Label "PC SELECTED" on Virtual Device

#... (some others commands)

~01@BTN 1,11,R OK // ACK for command from Master RC

The application catches the answer and changes the button color to "RED" and the label to "PC

SELECTED", as illustrated in Figure 8:
