I have spoken with their tech support and so far have them stumped.
The manual (and Chauvet-produced youtube video confirms) states that in SEND DMX 2 enter presses gets you into the SEND DMX options menu. Once there, the list should show 6 choices... starting with EDIT MODE, followed by 5 more. Mine (the latest, v1.3) does not have EDIT MODE, but rather DIMMER CHECK. The following 5 are the same.
Question #1: What does yours have?
Question #2: What does DIMMER CHECK (on/off) do?
Edit:
After hours of meetings, the engineering, sales, marketing, and support staff at Chauvet have determined that the manual and video are wrong and were based on the first iteration of the unit. However, support could not tell me what the function did. I discovered that it is a similar function, renamed. When on, channel settings are retained when moving to another channel. When off, they revert to 0. I don't see the usefulness of off, at all.
