Issues with existing profiles

Chauvet Q560Z Advanced mode - not able to control 'Shutter Strobe' parameter, either by encoder or command line. Parameter value remains zero.

Hello, David:

We believe this may be an issue with the "Strobe Mode" setting for the fixture.  The default mode is currently "Shutter Open."  In order for the "Shutter Strobe" parameter to function, one must first change the "Strobe Mode" to "Strobe 1 to 20 Hz."  This is set in this manner due to many requests from users that these values be able to be set manually within the profile.

Thank you,

Thanks, Sasha. This is what was going on. It doesn't completely make sense in this case, but I can see how it is consistent with the DMX profile for the fixture, so that's fine. Just on subject of strobe control, on Source 4 LED S2 Lustr QStage mode, the 'Shutter Strobe' parameter is user-bounded as '0 - 33Hz' but the fastest output rate is much slower than this. The manual just says 'variable strobe control'.

Hello, David:

How did you determine that the rate is slower?

The output range should be 0-33Hz, which is determined as follows;
The on pulse is always 10ms.  The shortest off is 20ms.  The total period of that range is 30mz, so one time in 30mz is 33Hz.

Thank you,

Hi Sasha, in general the strobe rate on these fixtures is much, much slower than the encoder value - just based on looking at the light output. I looked at it again last night, and it may actually be the case that the highest parameter value (33 / DMX 254) is 33Hz output - it is very fast - however the range on the fixture is definitely not linear. So with parameter set to 20 Hz, for example, the light output strobes at no more than 2 - 3 Hz.
