Networked Audio Tutorial
This tutorial demonstrates how to set up and communicate via a networked DIS radio using V+ between two desktop computers. There are many radio features available when using V+ that are not shown here. This tutorial is the simplest possible V+ design for networked radios in DIS.
This tutorial will work for cases where you need to setup just one computer to receive an existing DIS radio signal as well, just ignore the other computer.
This demo requires the items listed below. If SimPhonics' V+ Run-time System software is not installed on your system, you can download by clicking on the product name.
Complete the following setup on both computers.
Each desktop computer requires one V+ worksheet to operate. This file contains the Push-To-Talk (PTT) radio design and is installed with V+.
Complete the following procedure on both computers.
Assign one person to each computer. With headsets on, alternate talking and listening.
To talk on a radio, double click inside of the constant object to the right of the text Push To Talk (PPT). A control will appear as shown below. Click the screwdriver icon at the top right of this control and set 1.0 and click OK. Close the control by clicking on the top left of the control. When the control is set to 1.0 the transmitter is operational and your headset microphone audio is being transmitted to the other computer. When set to 0, the radio is receiving.
To add functionality, you simple add objects to the handle output pin of the radio. SimPhonics PTT headsets (available from SimPhonics) feature a PTT switch for example that can be connected to the PTT pin for control of the PTT switch from the headset. This is done through the Joystick I/O device in V+ since the PTT switch is exposed to V+ via a joystick input. In fact, a joystick could be used for this purpose also.
For example, the following graphic shows a radio connected to a wave file player object that could be used to simulate a jammer or generate automated chatter on the network from a wave file, or generate transmitted tones for secure radio types, and more.
V+ is a very powerful programming system. The applications are endless. Based on the objects in V+, if you can think of it, you can probably do it in V+. By using combinations of objects in V+, virtually any type of radio can be simulated from HAVEQUICK to secure systems.
