I do believe that you are wrong.  I also have an ancient but working
Diablo with the same configuration.

The DB15 connector is, if I remember correctly, for a sheet feeder (I
don't have one).  The DB50 (I think thats what it is called, is the
connector for BOTH serial and parallel input from the computer.

You must use the correct cable, which varies only in the manner in which
it is wired, for the type of interface desired.

Mine came with a parallel cable, but I do have the pin-outs for a serial
cable which I beleive are correct (someone please advise me if I am
wrong).  I haven't had time to wire it up yet, so I'm not absolutely sure
they are correct.

	Serial Interface  DB25 -> DB50

	3	24
	2	48
	20	49
	7	47
	5&6	25

You then need to set the switches inside the printer to conform to the
serial baud rate etc. that you intend to use.

I don't have the pin outs for the parallel cable, as I already had the
cable.

This info is not in any of the manuals that I am aware of.

Diablo (Xerox) Technical Support can still be obtained by calling
415 887-5903.

IMHO, the Diablo 630 is a wonderful, built like a brick sh*thouse
monstrosity.  I just hope the danged thing never breaks as no one can
afford the repair! (probably cheaper to buy another used one).
