FX9500 stopping reading instantly.

I've installed the EMDK for .NET and have upgraded the reader to the latest firmware. The reader has an IP address of and both the example application and my own application are reporting that the reader is successfully being connected to when reader.Connect() is called. The issue arises when I try to call reader.Actions.Inventory.Perform(null, null, null);. Again, in both the sample application and my own application the second LED on the reader does not turn on and no tags can be read. In addition the sample application displays 'Inventory Stopped' in the status bar. This leads me to believe that it is something to do with my config as the sample application is not working, however please feel free to correct me if this is not the case. Is there anything I can do to get some more debug information out of this in order to assist in pinpointing the issue?
