Matthew,
I have to disagree with you on this point. If you take a male and female
DIN and put them side by side, you will obviously note that pin matches
up with pin 1. So you build your DIN symbol to match a spec sheet.
However, when you rotate the part to hook up, you'll see 1 is matched up
with (e.g.)78. If you have mirrored one of the connectors pin 1 will
then go to pin 1 but you still won't be able to plug them together
because of either outer shell differences or keyway mating. I think the
original problem was that Ted was forced to build a part that doesn't
match the data sheet. All the engineer had to do was flip the symbol in
the schematic. That would have preserved the data sheet. Data sheets are
not irrelevant.

You should do it the proper way, not bodge it.
Bodging comes back to bite you later on.
AFAIKR pin 1 always goes to pin 1 on a connector, if it does not then
surely someone is mis-using the connectors. Even if you mirror it, then
pin 1 will still be pin 1, perhaps he actually has his other side
connected up wrongly?
I have had the 32 & 64 way DIN41612 (or whatever they are) connectors
placed every way & often making a mess of things by previous people in
my position, makes it awfully hard to know what's going on & has caused
me (who did it right, pin 1 - pin 1) to "cock up" a board or two because
the connecting one was wrong.
Do it right.

Subject: [DC] Din connectors
When building footprints for connectors do you follow the pin numbering
for the connector, or the mating connector? I know what the answer is
going to be, I am just fighting with one of the engineers over this and
I want to confirm that I am correct.
I have a 96 pin male din connector on the main board, I have a
96 pin female din on the daughter card. The female connector is mounted
to the secondary side of the pcb. I tried to tell the Engineer that
moving the pins around is only going to make things more confusing to
the assembly house. This was his response.
would you PLEASE use the same pin numbers that are on the XYZ.
the part data sheet is totally irrelevant.
it only plugs into one thing. it has no other use.
right or wrong the XYZ is the master document and the only reason for
the boards existence.
