DNC is 'Distributed Numeric Control' where the information is passed to several machines as in a network.
Unfortunately there is also another definition using DNC (Direct Numeric control) which refers to the program being stored on the host and drip fed to the machine.
Cadem use the first definition.
Drip feed loads the machine buffer with program segments as needed.
The listings of machine details they show has been contributed by users of their software, so it may just be that no one has bothered to confirm with them what para. and hardware work with the 900, if it was not changed greatly from 850 to 900 there is a good chance it will be the same, you may have to confirm this from a differnent source or from other users here.
