Global Parameters

DMX channels that apply to the entire fixture when pixel-mapping with VRGB and RGB VW profiles.

When using lights in multi-pixel modes, like the RR and R2, the standard DMX channel package can get quite large. For example, in Profile 2 each pixel uses 8 DMX addresses.

When this profile is used on a Q100R2 in 48-pixel mode, it occupies 384 DMX addresses per fixture. That's most of the addresses in a single DMX universe.

Global Parameters are used to minimize the DMX footprint so users have more available addresses in a single universe when using the maximum pixel count on the RR or R2 lights. It takes common parameters (i.e. CCT, +/-Green, etc) and applies them globally to all pixels. Then your per-pixel data is usually just the R, G, B slots. This reduces the overall DMX footprint of each fixture when using maximum pixel counts.

With our VRGB (Video RGB) Profiles 61-66, and RGB VW (RGB Variable White) Profiles 53-56, we utilize Global Parameters to help reduce each fixture's total DMX footprint.

Note

Global Parameters patch at the end of your pixel count. So with Profile 64, in 48-pixel mode, that would be 6 addresses per pixel = addresses 1-288 worth of pixels, and then addresses 289-293 for Global Parameters.

This profile is only 6 channels per pixel plus 5 Global Parameters per fixture.

When this profile is used on a Q100R2 in 48-pixel mode, it occupies 293 DMX addresses versus the 384 addresses noted above in the Profile 2 example.
