Is the profile the same as far as channel assignments, etc.?

Hey Len,

The latest version of the DS250 (v1.3) is exactly the same as the DS250 Pro. Older versions have some differences which are major as far as channel 16 (Fixture commands channel) goes. There are also some minor differences in other channels.

When I program intensity I just keep the shutter open through the cue and control the dimmer through a fader. For some reason, when I pull the fader down on the 250pro, the shutter doesn't close all the way. Will have to investigate further tomorrow and see if it's the entire rig.

Have you tried resetting the fixture via the console and/or on the fixture itself? Every once-in-a-while a fixture will do that on me and a reset fixes it.

Also, which console are you using? It might be an issue in the profile if it is doing it across more then one fixture. Are you using an old DS250 profile by chance? The old DS250 was at 0% intensity when channel 12 is at DMX value 15 vs 0 for version 1.3 and the DS250 Pro.
