  1. Thanks, Keith, that was it exactly - you need to hold down the GO button, then 'rS' flashes and changes to 'CL'. I must have missed that in the manual. All sorted! Nigel
  2. I have been using a Lightmaster XLS to control four analogue dimmer packs for some years, and we are moving over to DMX control (actually one DMX pack and a demux). When I connected up, the demux and DMX pack indicated they were receiving a signal, but I could only get one channel to respond and on an unrelated dimmer. Yes - I had done a super user reset, which, as I understand it will remap the dimmer to DMX output to 1=1, 2=2, 3=3, etc. However, because of pressure of getting the show going, we had to resort to ananlogue control. I investigated further, without time pressure. I did a super user reset again, and examined the patching (as per manual). It was all over the place and only one DMX xhannel in the range 1-24 was mapped to a dimmer channel. I then remapped channels 1-24 to their respective dimmer channels, and now everything appears fine. So I think I have solved the problem, but I do not understand why the super user reset did not restore the default mapping, which I understand to be 1=1, etc. The procedure is to press 'GO', when 'rS' is displayed, isn't it?

  3. There's a number of inexpensive demuxes availbable, e.g. Multi Exchanger from Thomann.
  4. A secondhand Lightmaster XLS would have 0-10V and DMX (for future development).
  5. It sounds as though you've found the problem here. I managed to repair a Sirius 24 which was, as bought on eBay, completely non-functional. Several of these LM324s had burnt out, together with two of the 4051s feeding them and a transistor and electrolytic in their power supply. Almost as though someone plugged the output into the mains! The PCB is clearly laid out in a logical way, though, which makes troubleshooting fairly straightforward. You may find it worth removing and reseating all the ICs as, over the years, the contact can become intermittent. Nigel
