The SL 1100 is a completely different animal versus the DSX.

Programming is completely different and models somewhat after the SV 8100.

When it first came out there was a certification on line which to me was a little raw and confusing,i did go thru it.

The best way is get registered with NTAC site and poke around on the site, which will answer many of your questions.

Is it the path to take ? That question would have to be judged
by the Installer using it. NEC should be around for awhile, so
That is one favor for the person getting involved.

Good luck with the SL 1100.
