Received my adapter today! Fits in the case great but I have a question about the ribbon cable for the master i/o unit.
I'm using a 4ms Row power with their shrouded bus stick.
The Master i/o cable has a red stripe which usually means its the ground.
However, the Master i/o cable has fewer pins than the 4ms bus AND the notch in the cable positions the red stripe up AWAY from ground on the bus stick. Is that correct or are the cables incompatible?
Thanks.
Vern

Could you post a picture of the cable and headers? EDIT: looking at the product photo on the adapter frame site: www.tangiblewaves.com/store/p48/AE_modular_Eurorack_adapter_frame_8U.html... it seems like the frame is just another Eurorack module with a regular ribbon cable. There should be a marking on the master I/O board indicating + or -12V. Plug the ribbon cable's small connector to it and follow the -12V wire to the TipTop header, making sure that it connects to its -12V as well. |

Hi, please connect the adapter cable at the MASTER module so it comes out to the left side without twists; then, the connector at the eurorack bus side should have the ribbon cable at the bottom part (where +/-12V is). Then everything is ok. It might be the case that the red stripe is not at the lower side (-12V) as it would be eurorack standard; this might have been my error.
And in worst case: The MASTER is protected against reverse polarity ;-)

Here’s 3 pictures. Note red Stripe is up not down. Cabels on Master i/o is factory installed. I will uninstall the master i/o to check cabling. http://instagr.am/p/BnWiAhbA7Dy |

That looks correct. Many Eurorack modules have thinner ribbon cables like this. The red stripe is usually -12V there, but on the AE it's apparently on +12V (which I think is also the "correct" way, but Eurorack did it the other way around). I would suggest to read up on the whole Eurorack power thing again, or check out my video  Don't look at red stripes for any specific thing, just follow the -12V wire in the ribbon cable from bus board to module and you will always be safe  |

Technobear, thanks for the link to your post. You wrote:
“Master module connection
2 Ribbons, one to eurorack, one for your modules (both supplied with AEM adapter)
Notes:
Eurorack : 12v RED Line at top”
I guess my cabling is correct. I know this is opposite Doepfer, which says red stripe should be down. People are going to install this cable backwards to their Eurorack bus sticks. My module came with no manual and I couldn't find one onthe Tangible Waves site.
Does the AE Master prevent burning out if the ribbon cable is backwards?

Nightmachines, Thanks for the advice. Your video was one I watched before. Also, Tom Whitwell's recent video on destroying a module. I did not power on because I had my doubts.
My Master i/o was factory installed on the Eurorack adapter, so I don't think I can see the modules -12 wire unless I take it apart. I need to find my hex tools to do that. I will just to make sure and learn good habits.
I really think these wiring discrepencies should be made explicit. There shoud at least be a one sheet with the Eurorack adapter.

yeah, unfortunately the AE Eurorack board does not have any markings on it (IIRC) and there is no manual  (hopefully robertlanger can fix this, as its important, even if its protected) however, I will say its reasonably obvious on the AEM side, as otherwise it would not 'exit' the adapter frame properly, you'd have to bend it unnaturally, so I suspect this would stop most getting it around the wrong way. funny this is all pretty topical after mylarmelodies 'rant' video yesterday on the subject |
