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. Regards, Ron Scott C.I.D.

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.

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.
