n00b question: DMX Termination

[PhantomD]

In what situations does DMX need to be terminated?

We are currently running 3 DMX dimmers in series, as far as I can see it's non-terminated.

[Chris15]

I'm certain this has come up before. Did a search yield no results?

[PhantomD]

We don't need the attitude matey.

There are no threads specifically on DMX termination, and I am not going to go through each one specifically.

Now is there anybody who actually has something they could contribute, please?

[CURLS]

Yes, we have covered this question in this DMX & No Dimmer forum very extensively.

Most dimmers terminate at the end of a series or daisy chained connection anyways but if they dont put a xlr at the end with a simple 120 Ohm resistor between pins 2 and 3.
But, to really answer the question dmx should be terminated at the end of all daisy chains whether it be dimmers fixtures color changers. fart i mean fog machines. Well you get the picture and refer to the previous forum as to why. Or just type "DMX TERMINATION" in google thats how I tought myself a lot of stuff!

Hopes this helps!

I am now no longer hungry b/c i just SuPeER GRAND SLAMMED MY ASS AT DENNY"S!!!

I know that I am not alone in getting rather annoyed when the same thing gets covered in more than one thread. It means that when I want to know something that I have to trawl through umpteen different threads to have a chance at finding what I am after. You said that you did not want to read through all the threads. I don't either and as far as I am concerned, this thread just adds another one to the list of threads I have to check if I'm after info on DMX.

I think the consensus reached was that if it is working fine without a terminator then it will likely continue to do so. If there are problems, try using a terminator and see if that fixes them.

It is not that I have a problem with you, it is that you have hit my pet hate, multiple threads asking the same question. We might both be Aussies, but that does not automatically make me your mate.

[PhantomD]

Thanks, I'll stick with the "If it ain't broke don't fix it" rule mentioned in that thread.

Because there is no termination and it is working fine.

[Chris15]

Did not someone also say that in some cases, it even works better without termination? I'd be sticking to the it ain't broke so don't fix it unless you start to have the dimmers going haywire.

Could you please explain what you mean by that?

[jonhirsh]

The blue room is another technical forum that has a reputation for being crass and snarky towards members who do not use the search feature.
http://www.blue-room.org.uk/

and that is the reason i do not feel a need to involve my self with them any more. An simple hey did you use the search feature would be enough.
