In parallel I contacted the support folks at Microsemi via their 
website.  They were kind enough to reply to let me know that the 142-615 
will not work with the downconverted XL-DC model above.  They suggested 
that perhaps a 142-603 or 142-610 would work so I'll cast about the web 
some more.

happy benchmarking,
