Wire length?

J12 cant go to J2. 4 meets 8...

J8 - J5 (5Pin)
J10 - J2 (8 pin)
J14 - J6 (6pin)
J11 - 1 (4pin)
J12 - ? (4pin)
J13 - 3 (4pin)

This is me guessing using logic, (5,8,6 pins is easy) comparing photos and the schematic

.
As I'm away from my main board and the number for the connector between HC & RS is obscured by a hole or some shit I can't see it...

Is this information out there or are people just guessing from the photos here

http://www.e-licktronic.com/en/content/ ... e-finished

I guessed from the images, and "knowing" where different drumsounds came out of the mainboard and "knowing" wher they would end up at the outputboard. And of course matching pin1 to pin 1 and so on for each connector.

Hi Hoffman, the way I figured out where each group of 4 wires went was by looking at the picture in the directions. It happened to be in color so I could follow each group of wires from the IO board to the main board. Also you are correct as to the order the wires go in. You can see a small number 1 and 4 on each side of the connector point on the main board, then it's just a point of making sure the wires coming from the IO board stay in that same order.

The order is all the same with each connector point having #1 being the far left and #4 to the right, if you're looking at the board from the side of the bass drum/first section which would make the sequencer to your left, bottom of the board. The picture I spoke of in the directions is located in the IO board section, last page.

I hope this helps you.

Thanks for the reply man.

See this is the problem. People having to make guesses from photos because they are not grade 10 nerds. Me included!
This should be in the build guide...

You're welcome, and that's a very good idea you came up with to help out others. clear and concise.

In my last Nava build I used a different connector for the power connection. This connector makes crimping redundant. You really need a very good (and expensive) crimping tool to do proper crimping. Mine (KNIPEX 97 52 34) was around 80 Euro. Don't even try to go with cheaper stuff, you will very likely have bad crimps!

The MTA connectors are cheap and you get very good connections without crimping. You need to press the wire in the connector from the side and then solder it from the top. On my build it looks like this:

For the power connection use 20 AWG (0.5mm) stranded wire.
For the other ones use 24 AWG (0.2mm) stranded wire.

This is the power connector (5Pin - J8):

The counter part is here (be aware that the images don't show the correct header):

For J1, J3 and J4 you can use these:

For J14 these:

https://www.conrad.de/de/stiftleiste-st ... 78343.html

For J10 these:

https://www.conrad.de/de/buchsenleiste- ... 78100.html

https://www.conrad.de/de/stiftleiste-st ... 78345.html

You can also find these connectors at Mouser and many other shops. Just type in the manufacturer number and you'll find them.

Maybe this is useful for some of you guys...

Hi all very useful advice thank you - I am waiting to get all the last bits before I open all of the nava boxes and attempt to build.

I have seen a few people mention the pre crimped cables which to me seems very sensible.

There are a lot of options online - can any one advise wether you need male - male or male - female please?

Its been nearly a year waiting for all my components to arrive and these, some SIL IC sockets and a component tester are the only things still outstanding so want to order right first time.

any ideas would be appreciated

regards

I've used coloured flat ribbon cables, so everything looks nice and tidy.
First I was concerned about the cross section, but they should work fine in AWG 28 (except for the 5 pin power distribution cable)
