Interestingly when you look inside a lot of fixtures, the male and female DMX connectors are just soldered onto one another in parallel.

Thus in essence if you are daisy chaining these fixtures, then you are passive splitting on the rear of the fixture. One leg is going into the electronics and one leg is going out to the next fixture.

Not saying it is/isn't OK... just saying, devil's advocate, maybe more people are passive splitting than realise it 😀

This is one of the arguments my colleague is making but when you look at some of the PCBs them leg going to the fixture has some circuitry I assume to act as an active split to the fixture but I'm no expert. 

Hello smart people.

A colleague and I have been discussing the topic of passively splitting a DMX signal. 

I am strongly against passive splits for DMX.

My colleague insists they are perfectly fine to use.

I know that it will work but it isn't the recommended or "proper" way to do it.

If possible I would like as in depth reason why or why not passive DMX splitters should be used as possible. 

We both are fairly smart people and have a good understanding of how DMX and rs-485 works.

Any additions would be greatly appreciated.

Thanks all.
