657x Digital How does digipat vector length loaded into card count against 128M Vector LVM?

Hi All,

I  pre-load about 30 digipat patterns to my 657x.  Each pattern is about 6M vectors long.  This would seem to be 30*6 = 180M Vectors loaded to card at start of test.  But, 657x spec says LVM is 128M Vectors.    I'm confused why I get no errors and the patterns run successfully.

Is there any documentation on what 'counts' as a vector against the 128M LVM?

Thanks
