[mod.computers.vax] DMB-32 printer interface info wanted

LLACROIX@carleton.EDU.UUCP (03/27/87)

Greetings--

We are upgrading our 11/750 to an 8530 (both VMS) quite soon now.  We have most
everything under control, except plans for our line printer.  We
currently have a Dataproducts B1000 attached to a Datasystems DLP-1132.
On the 8530 there is currently scheduled to be a DMB-32, and it is
our intention to run the line printer off the printer port.  My questions:
	a) What kind of a connector is on the DMB-32?  Is it a female
	   DB-37 like on the DMF-32?  Is it a pair of them (the DMF-32
	   manual shows connectors J13 and J14 as both used for the
	   line printer interface--I think)?  I would hope that
	   the DMB-32 and DMF-32 have compatible interfaces.  I think
	   that DEC recommends the same cables (BC27-A) to get from
	   either of these to an LPxx.
	b) Has anyone out there connected a B1000 to a DMB/DMF?  Do
	   you know what the pinouts are?
	c) Is there any real good reason why we shouldn't just buy
	   a DMF-32 instead, and hook it off our unibus?
The main reason we are considering a DMF-32 is that we need an RSCS
(JNET) link to a 2400 baud line.  We just saw a quote from DEC for
the software license and maintenance on the DMB-32 sync driver, and boy
is it pricey.
