Is there #### or a value or what do you see? Why do you use such an old Image Version for the Panel? (It has to be a Basic Panel 2nd Generation because a 1st Gen can only use up to V12 image, if you already have used a V14 image then you can also use V17 image. I would use the latest available Image for this combination) Bye Murof
