synlights Posted July 29, 2011 Share Posted July 29, 2011 Hi Guys, I was recently given a number of tigerscans and gs3s.. of which ive managed to get most of them working however one gs3 and one tigerscan have the same problem which im a little stuck on ... both work 100% fine when I put them on test via the dip switch on the base but once I plug them into a desk and try and run them over DMX they just sit there.. they both complete the test sequence without any problems.. As ive never run these fixtures before im wondering whether you could suggest some things to look at to sort this problem ... I have working units on site so can swap parts out to find problems ... just need pointing in the right direction cheers Link to comment Share on other sites More sharing options...
Mr Steve Posted July 29, 2011 Share Posted July 29, 2011 I had an issue with a Mini Scan that would complete the test perfectly, but go insane once DMX was applied. The only thing that fixed it was swapping out the main PCB (so I suspect the processor chip could have been at fault as I did the board as a whole). Failing that, might it be a dodgy DIP switch, possibly meaning that the address you are setting is not actually being set? Link to comment Share on other sites More sharing options...
synlights Posted July 31, 2011 Author Share Posted July 31, 2011 yeah was told it could be the chips.. but which one ?? thanks in advance :) Link to comment Share on other sites More sharing options...
JR Roughley Posted July 31, 2011 Share Posted July 31, 2011 HI Start by replacing the DMX line reciever chip, and make sure that the associated components supporting this chip are fine. Check for dry joints around the DMX connector in and out connectors. Swap the boards with other working units. Cheers JR Link to comment Share on other sites More sharing options...
