There is this distribution panel on eBay at the
moment, but I think
this might be the H3173-A version for the M3104 DHV11 / M3107 DHQ11
Yes, it is - I got several of those from him, but he only had one of the
DZV11/DZQ11 ones (which are, simply by looking at them, indistinquishable
from the DHV11/DHQ11 ones - one has to look at the part
numbers to
distinguish them, they are so similar - well, to be hyper-precise, there
are
two variants of the DHV11/DHQ11 one, one with the Berg on the side, and one
with the one of the top, and it's the latter which is visually almost
identical).
The 70-19964-00 distribution panels I have for the
M7957 DZV11 / M3106
DZQ11 have arrows screened on to the front of the panels between the
DB25 connectors. (I'm not sure what the arrow is supposed to indicate).
Which way around to install them, or which port is #0, would be my guess.
I've seen a similar arrow on the dist panel for the DLV11-J (which also comes
in two distinct variants).
