The Virtual Device – an Application Example
5
The VIRTUAL DEVICE Screen
The Virtual Device screen includes three buttons that trigger the switching of a switcher, scaler or a
similar device in the room1Figure 4 as well as a “Select Source” text label, see .
This screen is duplicated as the Virtual Device in the K-Config Virtual Device triggers layer.

K-Config software is used to write the control action list to the K-Config Virtual Device triggers
layer; and once the end user presses a button on the Virtual Device, this list of actions is executed.
3.4 Functionalities
The following sections describe how to:
• Establish a connection to the Master RC (see section 3.4.1)
• Send/receive data to/from Master RC (see section 3.4.2)
3.4.1 Establishing a Connection to the Master RC
The Virtual Device can be connected to the Master RC in various ways.
In the example described in section 3.3.1, the SETTINGS screen is used to enter the IP and the
K-NET ID, after which the CONNECT button is pressed to establish a connection with t he Master
RC.
Alternatively, this handshaking procedure can be executed automatically by the application upon
startup or within any other developer-defined event.
In any case, the connect procedure opens the UDP connection and once a connection is established
the Virtual Device sends the Handshaking command (see section 4):
