16bit scanner programming issues

that sounds like an issue i was having with some Techno Beams......what lighting fixture are you using?

Martin 918's and 518's....I think the issue happens with any 16 bit light but it is really noticeable on scanners because they react instantly. Just look at the DMX output window when you trigger the cue and notice the problem is somewhere in the software, not the lights.

Try a few things for me, see if we can narrow down the issue a little bit here. I attached a link bellow to the 918 user manual, the data and layouts are similar between the two types of lights. First, on page 12/13 of the manual it tells you how to reset the fixtures to default settings. This will clear up any preset issues that might cause errors in the data. Second, on page 14, it tells you how to set the mode of DMX...for the controller you are using, Mod2 is what you want. The Vector mode is more for when you have a fader control where you jump scene to scene. (mod3/4) if it is Vector, it is told a point to go to and a time to get there....it could possibly be getting a feed back after the scene is finished (that is what was happening with the Technobeams i was using) I reset it to normal default in 8bit and it fixed the problem.
Now, if it is in vector mode and your scene is set to loop, you will get that twitch because it is being retold to go to that point X in y time frame. So, the last thing to do is open up the scenes and make sure that you are not in loop.

The last thing to do as well is double check with data mode the light is set too. These lights have a hardwire mode that you can change from DMX to the Martin Controler. This controller, the 2/3 pins are phase reversed. To check that your light is in the correct mode, check page 19 in the manual "Changing the XLR pin-out"

Let me know how it looks after all of that. Hope this helps you out.

I know for a fact they are in MODE 4 right now. I will try MODE 2 and report back. It might be a few weeks, I'm not around the lights a the moment.

awesome, let me know

Here's what I have found out. MODE 2 was no different, still having issues. However, I found that you don't even need to fire up the light to see that there is a problem because it is apparent in the output window. In fact, I chose another fixture to try and it still happens. The issue occurs with any 16 bit fixture! The fine pan and tilt channels will go to zero, then right back to their values when the fade completes.

can you save your show and send it to me in an email? i want to see exactly how you have this set up...im not able to see what you are saying. When i set up those exact lights, the fine P/T do go back to zero exactly how the fade should work, but do not go to the values like you are talking about. If you could send me the show, i might be able to see if that is a setting issue or what is going on
