The
Refresh-button lets you query the current state of the ROS masters from all running master_discovery nodes.
The icons
and
show whether a connection to the host exists. The color of the
icon indicates the connection quality as determined by the master_discovery node.
The
next to each host name indicates whether the parameter servers will be synchronized by the master_sync node. You can toggle ROS master synchronization by click on this icon. A synchronisation dialog with additional options is available by
button on the `host description panel`.
The multimaster capabilities are disabled, if the local ROS_MASTER_URI is referenced to a remote host.
You can initiate the discovery process with the Start-button on the ROS Network widget. The discovery node can also be started on a remote host. Click on the Start-button and enter the hostname or IP address in the dialog below.

If no multicast communication is available sets the static hosts parameter to the list of availabele hosts separated by comma. This also increases the network load!
On problems while launch master discovery or master sync on remote hosts you can use
to get the log output from these node.
