[I got diagnosed with bipolarity disorder last year] -- I'm sorry to hear about that!!! And, please do take care, OK??? A good engineer friend of mine also had a "bipolar disorder" and he had a really tough time controlling himself, even to the point that he had decided to commit suicide while driving his car.....WITH ME IN IT!!! ..... He ended up being successful in his endeavor a few years later.☹️

GOOD LUCK!!!

Don't worry i don't drive ;) Thank you for sharing your experience. It tells everything.
 
...... As of yet, I have never seen any mechanical detail drawings showing this specific side-view aspect of the edge-connector to PCB-edge dimensions. THIS is a first!!! THANK YOU!!! for sharing this view and their dimensions!!!
They are not their dimensions. They are the dimensions that I worked out which only require a little attention.

If there is to be a "GroupDIY '500-Series' Format Standard", then every last friggin' and minute detail needs to be specifically defined.
There is already GDIY 51x format which differs from the VPR format that it is 11 slots wide with added + - 24V operation. I now have given all the critical dimensions. The rest is utterly unimportant and left to the manufacturer as long as the final end product rack fits in a standard 19" format cabinet.


I also believe that -- possibly -- due to the large worldwide customer base that this GroupDIY forum represents, having the lot of all of us coming up with "a settled upon and a collectively ratified set of electrical-details and mechanical-design dimensional criteria and parameters".....just -- might -- persuade all of the "BIG BOY COMPANIES" to modify their so-called standards and instead adopt what it is that we all have come up with!!! At least.....we can "dream", can't we???

No limits in dreaming, but if you think API or Radial are going to read this thread and change their products, then you are being naïve.

With my previous post I now have given all the critical dimensions. As for the electrical specifications, again the card edge pin configuration is already there.

However, you are of course free to design your own version.

[if you think API or Radial are going to read this thread and change their product, then you are being naïve] -- Something you don't know.....I once worked at the same concert sound-reinforcement company as the president of API, Inc. also once did, during the same time-period. And.....I also have his personal e-mail address.

You never know.....ya know?!?!?!?!?

Perhaps I am confused, or perhaps there are some crossed wires happening in this discussion.

Are we talking about establishing dimensional standards for a 500 module, or a chassis?

[Are we talking about establishing dimensional standards for a 500 module, or a chassis?] -- I don't know. Since (I think) most of the issues on this forum seem to be about the front-panels, that is what I thought this thread was mostly about. I could be wrong though. Other members seem to enjoy pointing that out.

However, since there has been some discussion about the electrical specifications and a whole bunch discussed about the front-panels, then we just might as well throw in the rack-chassis as well. You know, like at McDonald's.....a "Combo"!!! "Do you want Fries with that"???

Actually.....-- maybe, just maybe -- if the entire entity of all of us on here can actually come up with an entire set of electrical and mechanical details, as well as their specifications and a complete set of schematics and mechanical detail drawings (hint, hint) which covers -- ALL -- of the bases concerning a "GroupDIY '500-Series' Format Electrical & Mechanical Specifications Standards" document, that document would then be presented to all of the "Usual Suspects" within the professional audio industry for their consideration. With these documents clearly explaining all of the current shortcomings and confusion within the so-called current "Standard".....then maybe the industry will be able to see and understand for themselves how the current "Standard" needs to be updated and revised and something new adopted industry-wide.

On top of all of that, this new "GroupDIY '500-Series' Format Electrical & Mechanical Specifications Standards" would -- NOT -- be controlled, owned or dictated by any one company as the current "VPR Alliance" is by API, Inc.!!! -- THAT'S JUST NOT RIGHT!!! --

My inflationary devalued 2-cents worth.....

I will add to that (and it's a Noob question, please be parient and kind to me):

If we already have a 51x specification, why would we need to stablish our own 500 standard? Aren't they compatible? I was under the impression they were.

Also, why is nobody (CAPI, Sahib, Volker) selling the 51x anymore?

I still do. Currently a new batch of metalwork order is in place.

I think Volker and Jeff have also run out of metalwork.

I think we are most talking about modules. People here I suspect tend to buy a rack but like to populate it with some off the shelf modules and some they build themselves.

In my mind, the main target of the spec is people designing modules.

I don't think we need to go into details of the chassis as long as we are confident the module spec is comparable with what is currently available.

I think what we need as a definitive mechanical spec for a 500 series module.
