The availability of the Receivers in the Listen To tab is indicated by the following icons:

not connected the Receiver cannot be synchronised because is not currently connected to the tRio server.

circular the Receiver cannot be synchronised with because it is listening to this unit
standby the Receiver cannot be synchronised with because it is in Standby mode
private the Receiver cannot be synchronised with because its access level is set to Private
protected the Receiver can be synchronised with, but not controlled by this Receiver
  public the Receiver can be both synchronised with and controlled from this Receiver


Troubleshooting

Getting "The page cannot be displayed" error.
  1. Check that the tRio Server is running.
  2. Check that the xxxx part of the address points to the correct host name or ip address.
  3. Check that you have not missed out the :8090 part of the address.
  4. Check for the "Warning: LocalHost lookup failed" message in the tRio console (see below).
Getting "Applet failed to initialise" error.

Ensure that you have installed Java 1.4.2 as the default plug-in for your web browser.

This can be confirmed by looking at the very 1st line in the java console (accessed via the coffee mug in the System Tray). It should read:

Java(TM) Plug-in: Version 1.4.2

 

Drag and Drop not working for from shoutcast.com
  1. Ensure that you are dragging the icons and not the station descriptions.
  2. The stations must be dropped into the Player tab.

 

WARNING: LocalHost lookup failed. You may experience problems connecting via the Web font-end. Please specify the host-name in trio.xml.

If this message appears in the tRio console then change the following line in trio.xml:

<rmi create-registry="true"/>

to:

<rmi create-registry="true" host-name="xxxx"/>

where xxxx is either the host name or ip address of the machine that the tRio server is running on.
