Monitor Property Box
In the network panel, click on a monitor icon and select Properties... in the popup menu.
Audio Video
Audio On: Check this box to enable the audio of both monitors connected to the same receiver (see note below). When the audio is enabled, a small loudspeaker is added to the monitor icon.
Audio Volume: Use this slider to set the volume to correct level (see note below).
Video On: Check this box to enable the video to this monitor. No video is sent to the monitor when this box is unchecked and the monitor icon should be grey.
Note: On the contrary of video, the two monitors connected to the same receiver are supplied with the same audio. These monitors are close to each other, so I would make no sense to use different audio settings to back to back monitors. Audio commands apply to both monitors. If monitors are different or need different audio settings, use the monitor specific settings to do so.
Connection
Set up the serial RS232 monitor connection. The monitor serial interface must be configured for 8-bit, one stop-bit, no parity-bit.
By using the Bit Rate combo box, select a data rate from 1200 to 115200 bps, or (recommended) select Same as Broadcaster.
Bidirectional Serial Connection: Check this box if your monitor need a bidirectional connection - touch screen monitor for example. A small double arrow is added to the monitor icon when the receiver provides a bidirectional connection.
Note: If several monitors are using bidirectional connections, the result is unpredictable if several of them "speak" at same time. There may be a mix of monitor responses at Player level like if they were transmitting on same wire. The default DS Network implementation does its best to guaranty that all messages are carried to their destination, but cannot provide any protocol to discipline the monitor responses, since it does not know how the Player and Monitors work. However, any protocol implemented by the Player and the Monitors will be transparently carried by the DS Network.
DDC
To simplify, we can say that DDC (Display Data Channel) is a VESA standard that rules the information sent by monitors to computers through the VGA interface for plug and play connections. The computer OS and video driver use this information to set up the video card according to the monitor capabilities. If the computer does not receive this information, it assumes that the monitor is dumb and uses default values that may not fit the monitor requirements.
In a networking system such as DSNet, the Player computer may be connected to thousands of monitors. DSNet allows to use one of these monitors as model. The broadcaster will send a copy of the model-monitor DDC information on each Player request. Of course, it is easy to understand that things will go better if all monitors in the network are similar to the model monitor.
Click Capture Monitor Information to read the monitor DDC information
Click Send to Broadcaster to use this information as model. Starting from now, the broadcaster will emulate this monitor model.
