NovaHot1,
Core clearly state that Datajack provide DNI (p. 222) and core clearly state that you can link DNI wireless (p. 163).
Since the two entries are spread apart it might be possible to miss; hence Mission added it in their FAQ
...but how you still can argue (after 3 pages) that core doesn't say that Datajack provide DNI and/or that DNI cannot be linked wireless is, to be honest, rather ignorant.
Did you maybe miss a word when reading the description of Datajack (p. 452) when it clarified that it also (as in addition to wireless) comes with a cable that let you directly interface....?
