Dear rockers,

I am working on including the Vicon component to my RoCK network of 
components. I run the test_vicon.rb script provided with the Vicon 
component but I only get NaN NaN NaN repeatedly in the output.

I am using a Vicon setup with 10 cameras (MX 13+ and T20) and the Vicon 
hubs Ultranet and Giganet. I am running the Vicon Nexus (version 1.8.5) 
software in a Windows PC that is connected to the hubs. This machine has 
an additional network card to connect to the lab network.

I have properly provided to the RoCK execution machine the IP of the 
Windows PC (ping is successful) and defined the Subject and Segment that I 
want to track.

I have the feeling that I am missing something in the Vicon Nexus software 
environment to make it ready to provide in real-time during the test the 
position and orientation data of the subject that is being tracked.

Someone with experience using the Vicon component can point me in the 
right direction here?

Kind regards and happy holidays,
