First, awesome progress.

Second, the Binary Output parts do in fact need to be added to the c1sus model.  They don't need to appear in the IOP though.  (They are somehow automatically taken care of by the IOP code). 

It looks like in the 2004 revision in SVN, the cdsCDO32 part (located in the CDS_PARTS.mdl/IO_PARTS) was broken.  I fixed it and updated the svn with it, so a svn update should pull the corrected version.

I'm not sure whats wrong with the DAQs.  I'll try to take a closer look at the model file tonight and see if I can make suggestions.  When you write outputs on DAC_0 or DAC_1 is the C1SUS GDS TP screen showing anything?
