Soundproj-x Posted February 5, 2006 Share Posted February 5, 2006 Hi guys, I`m pretty new to this light, and I`m having a few probs programming it.the main problem is that it seems to be on a starting address (STCO) of 252. Does anyone know how I can change this down, because were only using a 256 channel desk.Cheers for your helpDave Link to comment Share on other sites More sharing options...
TommyToad Posted February 5, 2006 Share Posted February 5, 2006 Use the menu on the lantern. The lcd. Link to comment Share on other sites More sharing options...
P. Funk Posted February 5, 2006 Share Posted February 5, 2006 If you don't know much about them, the manual may be a better place to start than this forum - you'll get answers much quicker from a document designed to give you them! http://sse.martin.com/service/downloadfile...EN_E.PDF&cat=65 Link to comment Share on other sites More sharing options...
Soundproj-x Posted February 6, 2006 Author Share Posted February 6, 2006 Worked it out,We had the manual with us, but it was no help. Our problem was that the DMX start code on the screen was stuck on 252 with no way of changing it, and we obviously wanted on 0. We then remembered a problem we have come across before when we plug our NJD merlin desk into Martin lights, and that is the DMX +/- is reversed.So we plugged our pre-built reverser in and away it went, with a start code of 0Good old NJD, with their wisdom of reversing DMXCheers for your help anyway guys!!!

david.elsbury Posted February 6, 2006 Share Posted February 6, 2006 *nods confusedly*Why would the unit not let you change the address unless the reversing adaptor was in place? That doesn't sound right.... David Link to comment Share on other sites More sharing options...
paulears Posted February 6, 2006 Share Posted February 6, 2006 .... and I didn't know DMX address 0 was actually accepted - I though 500's start at 1 like everything else? Very strange. Link to comment Share on other sites More sharing options...
johnhuson Posted February 7, 2006 Share Posted February 7, 2006 I'm with you guys, doesn't sound like a MAC 500, or any moving light that I know! Link to comment Share on other sites More sharing options...
Tom Baldwin Posted February 7, 2006 Share Posted February 7, 2006 I don't think the OP was trying to change the DMX address, but rather the start code. If the MAC believed it was receiving Martin protocol (I'm right in thinking that the 500 was one of the last fixtures which could understand this, right?) - a possible outcome of phase reversal - then the start code might be other than 0. Once the MAC worked out that it was receiving DMX, then it would (should) be looking for start code 0.I think the OP might be a little confused about address vs. start code?

Soundproj-x Posted February 8, 2006 Author Share Posted February 8, 2006 Just to clear things up, this is what was happening. We plugged our new mac 500 into our njd merlin desk, The DMX light on the panel was instantly illuminated, we then tried to operate it with the mac in DMX4 mode, and the desk channels set 1-16 with corresponding sliders and the sliders at 0-255. But nothing happened, no life from the mac on any slider in any position. We then started looking at what the unit was set at, so looked through the manual checking all settings and personalities. We then got to (STCO) via (DMXL) in the menu, and it was displaying 252 and would constantly flicker to 254, so we thought this was the problem and hence my first post.The next day when we battled a little further, we remembered how in the past we have had to use a reverser in the chain to most non NJD lights, so we plugged one in, and hey presto, the mac fired up, and the home display was now showing 1, (which it wasn't before) So thanks for your help anyway guys Link to comment Share on other sites More sharing options...
goochr96 Posted February 8, 2006 Share Posted February 8, 2006 Hmm, sounds to me that it was your desk that was confusing things, do NJD use non compliant (backwards) DMX pin out wiring? Link to comment Share on other sites More sharing options...
Soundproj-x Posted February 10, 2006 Author Share Posted February 10, 2006 yes, Data + = pin 2, data - = pin 3 and earth pin 1 Link to comment Share on other sites More sharing options...
