5pin 3pin DMX

Simple, that is NOT DMX. The other two lines in DMX were for expansion that never happened. Some companies try to use them for other things, most common being a second universe. What you have is the more dangerous of the two, running power down the line. You can fry all your DMX drives in your controllers and/or fixtures that way real easy.

That Datamoon must use some sort of proprietary controller and/or adapter. You won't find anything that uses DMX standard that sends power down the line. 4 pin is different just for this reason. You don't end up frying something even though they could have just used 5 pin instead and not needed another type of cable to control things.

Edit:

Yup, I was right.
"3) Externally controlled from any DMX controller such as
Merlin, IQ-MX80, IQ-MX60 or IQ-MX40. see page 7
The Datamoon may be controlled from the Merlin, or any of
the NJD IQ-MX range of controllers, or any lighting desk with DMX
or 0-10V analogue outputs.
4) Analogue control from a 0-10V output controller
(Touch panel, or AR1 remote controller) see page 10.
0-10V can be used to directly control the colour and
movement, or to select the sound animated patterns."

It lies, DMX does not put out 0-10v on any line. According to the 2008 revision, pins 4 and 5 may only be used for an optional secondary data link aka another universe or control method (like rack monitoring, etc), not power.

Right that sounds okay, so if i just get a converter from 3pin to 5pin i should be able to link this up in my chain of DMX lines and run it via My DMX (sorry abit of a novice)
Thanks Mark

No, Serra was pointing out that the specs are wrong even on the product page. You cannot use this fixture with my dmx. Sorry.

Ummmm right, i just been playing about with it for abit and i have got it working with my dmx, think i just need to make a profile for it because all the controles are all over the channles at the min.
Thanks Tho
