Just been pointed at this month's L & S I, where on page 100, a rather bold statement has appeared, causing a couple of people I now to have a bit of a flat panic!!

Now, without starting into the whole 3 pin vs 5 pin discussion/argument again, what I do find is that this is a rather inflammatory statement for the industry mag to be making...
And of course, whilst there may be some who'd LIKE it to be illegal, it most certainly is NOT!!!

I've dropped the LSI editor a quick mail suggesting an addendum to clarify might be worthwhile.

I had a great business plan ... I was going to build bungalows for Snow White's seven dwarfs...
However, there was just one tiny flaw .............

If I spent my time correcting LS&I I'd get nothing else done.

While 3 pin connectors contravene the standard, the standard itself has no standing in US Code or UK Statute Law so there is no Law to contravene.

Would RJ45s also be 'illegal' too? The only connector that used to be in the spec was the 5 pin.

I seem to recall RJ45s are in the standard, together with with a pin out for cat5.

Inflammatory, incorrect, and pointless. LSI should know better.

The word illegal is often used in computing, such as illegal command / illegal operation - it just means against the rules of the current context.

Even chess uses the term for moves which are not allowed - but I don't think you'll end up in jail for being bad at chess.

The spec says 5 pin must be used, unless the physical size of the XLR connector prohibits its use. As 3 pin connectors are identical in size, that means it's not acceptable. RJ45 however is allowed as it's smaller (not sure where you'd stand with EtherCON, but I think that's just delibritely picking holes in the spec!

This is funny as Artistic Licence also sell product with 3pin XLR connectors.

Yesterday being dated 5/12 across the pond led to my Facebook being filled with various DMX related posts, including some pretty militant views about the use of 3 pin. The posters were not just some random lampies, but actually pretty influential people in the US production tech scene. I'd not be at all surprised if some states didn't make using 3 pin for DMX a capital offence, so strong was the sentiment.

Don't even mention Cat 5 cable or RJ45.

CAT5 /5e/6 is much better than audio XLR for DMX transmission!

I find this quite surprising, in my experience 3 pin DMX is widely used in the UK events industry. I don't do all that much theatre stuff, or any global touring productions or anything like that so that might be different. Maybe it is just the medium budget range events I tend to work in, but a lot of fixtures provide both connection as standard.
