PaulCasso Posted December 14, 2012 Share Posted December 14, 2012 OK . . . last night I was given 6 of these lights to incorporate into a in-house lighting rig.Not having any info on the I first plugged one up to my Enttec DMX Pro and using Pro utility found they were generic RGB+dimmer/strobe total 4 channel.Having tested on DMX ch 1-4, I then patched the 6 fixtures from 47 upwards !Problem . . . . . . when the fixture on the first of the 6 (ch47-50) the dimmer/strobe ch50 the fixture only worked as intermittent strobe ! 0- 250 nothing 255 FL a flickering strobe !When the DMX address on the fixture go's into 2 digits ch4 go's mental fixture unusable ! Anyone else had this issue or used this model ?Don't want to have to use and patch in pairs or have to re patch all my other moving heads . . . . . . . . just to get them on the first channels ch1, 5, 9 Also we have the smaller led version of this fixture 153.778 and they work great !

timsabre Posted December 14, 2012 Share Posted December 14, 2012 I am not familiar with these particular fixtures, but normally when this happens it is a problem with DMX being sent out too "fast".Most lighting consoles leave a little bit of idle time in between each DMX channel value, however DMX USB dongles often don't have this idle time. If the microprocessor in the fixture is struggling to keep up with the DMX data this will cause it to randomly drop channels causing flickering and odd behaviour. However it will work fine on a low DMX address because there's less chance of dropping channels. Unfortunately the only fix is to use a different controller or patch the fixture at low addresses. The Enttec interface allows you to adjust some of the timings, but unfortunately not the idle time. Link to comment Share on other sites More sharing options...

Thanks Tim,I spoke with Kevin last night to see if he had a fixture patch for it, unfortunately he couldn't help.In Showmagic can the idle time be changed Tim ?Regards,Paul C Link to comment Share on other sites More sharing options...

I don't know, if you mean Kevin from showmagic then he is the man to ask. Link to comment Share on other sites More sharing options...
