stuartsl Posted April 24, 2008 Share Posted April 24, 2008 Heya, I'm planning to use a load of Chroma Q DB4's to uplight a load of white flats, but I've been reading up about them and they look all too confusing to use...all I want is to access is simpe RGB from my desk, three channels, so I can program in my own colours, the same on each block, so each block should have the same start address, I was reading the manual and it was talking about up to 16 channels?! any thoughts would be greatly appricated, Thanks in advance Stuart Link to comment Share on other sites More sharing options...

peternewman Posted April 24, 2008 Share Posted April 24, 2008 do you set the DMX address on the DB4's them selfs or the PSU?Yes just on the PSU (at least I'm 99% certain that's the case, it's been a while since I last used some). Link to comment Share on other sites More sharing options...
stuartsl Posted April 24, 2008 Author Share Posted April 24, 2008 so does this mean that if I was to have 5 DB4's running off one PSU I could not control each individual block seperatly? as if the DMX address is set on the PSU I dont see how it can control individual DB4 blocks??

paulears Posted April 24, 2008 Share Posted April 24, 2008 Stuart - there's a nice table in the manual that shows you how to set the things up as a 5 individual blocks, individuals, or all as one! Link to comment Share on other sites More sharing options...
peternewman Posted April 24, 2008 Share Posted April 24, 2008 The communication between Colour Blocks doesn't necessarily, and indeed probably doesn't use true DMX, so it can control each indvidual DB4 and indeed each pixel on each DB4 by addressing them depending on the order they are connected to the PSU. So at a guess the first one will take the first three control channels and then only send on everything after this, so the next one takes the first three it receives (actually 4-6) etc. If you run in Mode 3 you get RGB control of 20 cells (5 fixtures on the PSU and 4 cells/pixels on each DB4).
