This is per the manual on the various panel.cfg files..
To activate and animate the LSO, add the following lines to the panel.cfg for the aircraft you wish to use with the CV-6.
WindowXX=Batsman//--------------------------------------------------------
[WindowXX]
size_mm=256,256
windowsize_ratio=1.0
window_pos= 0.75, 0.0
position=8
visible=1
ident=10004
gauge00=vstudios!LSO.xml, 0, 0, 256, 256//--------------------------------------------------------
No rocket science here. I did notice that the entry references an xml file instead of a specific gauge. the vstudios folder is in the right location with all the right files.
