 The LAV-11 is limited to LA180, the LPV-11 is configurable for LA180
 I've used both for "other" though the LAV-11 needed a few red wires. 

I'm late to this discussion so I'm not sure exactly what
is needed. The LSI-11 Systems Service Manual has a page or
two on both the LAV11 and the LPV11 (and I promise to start
uploading it all to manx tonight ...).

The LAV11 uses a BC11S cable for the LA180 and a 7009087 for
Centronics models (101, 101A, 101D, 102A and 303).

In the case of the LA180/BC11S, the P2 end of the cable attaches
to the LA180. You also need to fiddle with the LA180 jumpers and
the LAV11 jumpers. The LPV11 is the replacement for the LAV11.

If what is really needed is the pinout of the BC11S, then 
none of this will help (unless knowing the cable type helps
- there seems to be one place on the net selling these).

What is missed being late is the printer at the end is not a DEC
LA series or DataProducts.  He wishes to use a PC compatable 
(centronics) printer.  Thats doable but the cable is not DEC
stock though one could be modified to match the pinout.
