DIN 41612 cable
« on: March 19, 2014, 06:46:14 am »
Where can you buy an assembled  DIN 41612 extender cable, like in the most recent eevblog video:


I 2 of these cables, ~2 feet long. All I can find is websites selling the connector... but I want an assembled cable like dave jones has.

The cable Dave has (ribbon) will only have rows A and C connected B is not connected. Not a true extender. Easy to make if it will do.

ok, what do you propose? I have a test equipment I need to get a card out of. The extenders are not available.

should I buy that, get a segment of parallel cable and solder it?

I have done this in the past, but remember wires are delicate and you will need to be careful. Extender cards are better, more robust.

Get 8 pcs of these (the listing is for 5)

http://www.ebay.ca/itm/New-5PCS-20cm-Dupont-Wire-Cable-8P-8P-Pin-Header-2-54mm-Pitch-/330737532282?pt=LH_DefaultDomain_0&hash=item4d017e3d7a

Get 6 of these (most people have these, listing is for 10)

http://www.ebay.ca/itm/New-10pcs-40-Pin-1x40-Male-2-54-breakable-pin-header-3238-/171186838668?pt=LH_DefaultDomain_2&hash=item27db87dc8c

- Check the cables and make sure the pins are correctly inserted.
- Plug the cables into the socket and put hot glue on the point in which the wire enters the connector. Once set you can remove. To assist with removal you would can put teflon tape in between the connectors and use that to pull the connector out. You need to add it before you start. The teflon tape lays very flat and slips nicely.
- Next you will need to make a gender changer to plug into the other end. Use the header pins, you will need to solder them end to end to get the necessary reach. Use the existing female connector to get the alignment correct. The holders for these pins are plastic so unless the are held by the connector they will not align correctly. Once done attach the other end of the cable and use hot glue to secure. Make sure it cools fully so the pins don't shift.

Use masking tape to catch drips of hot glue. Don't apply glue the original connectors only the one you are making. Check pin alignment and adjust before insertion.

Use the shortest wire possible.

well how about just buying the actual din 41612 socket and then buying a very wide ribbon cable ( i think they sell them at like 200 wires wide) and solder it? Like using 2 of these, a strip of wood and ribbon cable to make a ghetto extender card:
http://www.ebay.ca/sch/i.html?_trksid=p2047675.m570.l1313.TR1.TRC0.A0.H0.X+din+41612+&_nkw=+din+41612+&_sacat=0&_from=R40

what you propose is what I was originally going to do many months ago but it seems like a lot of effort and VERY bootleg, so I lost drive, but if you say it works I might as

well.. I have the materials on hand to make a frankencable but I just figured that the reliability of epoxying a bunch of headers and shit together would be pretty bad. IT worked out OK for you? I would not mind saving some dollars, good tip on the teflon tape thats a trap for young players no doubt

If the board you have is 96 pin then you need 96 pin, double check that. I used the method I described because that it stuff that I had stocked, and it is cheap. Regardless of what you use the length of the extender can screw up your circuit (even a pcb based one).

Here is a link for a VME extender, it should work but you may have to slice it up the middle. Very good price for what it is.

Yes, the unit I have is 96 pins. Are any pins shorted on that VME card? I cannot tell from the pictures.

I've never seen it (shorted pins), typically the power traces are wider other than that nothing.
