Thanks for checking bitzerj!  Just to confirm, in CCP you are editing the MX-990 and not the MSC-400?  If I edit the MSC I see the ports but when I switch to editing the MX990 I do not.  What I mean is:



This is with a brand new clean project where I just added an MSC and MX990.  The MX990 is the one selected (double-clicked) in System Designer.  So I have no idea what the problem could be if you can see them and I cannot.  This is on two different machines.
