The DA15 video connector on the DECmate II (and Rainbow, Pro 3xx series)
carries the signals for an LK201 keyboard (the one used with the VT220,
etc terminal), a 12V power output to run a mono monitor, and composite
video. (RS170 -- I think that's the right standard -- US TV anyway). The
Pro and 'bow support a colour video card (I have no idea if the DECmate
does), and then you also get RGB (sync-on-green) video on this connector.
I can find a pinout if you're interested.

AFAIK you can't use a dumb terminal on a DECmate.
