I like this look. How do you anchor the truss? Is it just sandbagged, or do you have a base or ropes that aren't visible?

On most info sites, they talk about each channel going from 0-255. The board that comes with the package goes from 0-100. Is that the same thing only on a different scale?


How 'bout some specifics?  What board, etc.  You're probably correct in assuming so.  

And you'll probably get a better response by starting a new thread rather than putting a new subject in an old one.

Those are probably anchored to a base plate, a big, heavy piece of metal with wholes in it for bolting truss ends to.  But they should also be tied off at the top as nothing is 100% secure on one point.

I use 2 different methods to stand the truss upright.  The first is a simple flat baseplate. I have a pair made of diamond plate aluminum and 2X2 aluminum tube. I also have a pair of wooden baseplates made of 3/4" plywood and 3/4" plywood runners.

The flat baseplates are used when I stand up two sections (16' high total) of single hung truss.  I bolt the baseplates to the truss and weigh them down with about 150 lbs of sandbags or stage weights.

I also have a pair of wooden boxes I built. I wanted to have different heights of truss standing up, and a single 8' section didn't seem tall enough for me, so I built 3' high boxes. These boxes are made of 3/4" plywood  and 2X4 bracing, and have an open back so you can reach in an get to the bolts.  In use, I stack about 75 lbs of sandbags or stage weights in the box for stability. I only use a single 8' high section with a box base.

I have only used the truss standing up on sturdy stages at corporate type shows. I have not had a problem of the truss swaying or being indanger of falling or bumped into. I will only stack two section max on a baseplate and one section on a box.

Hello there

The DMX signal that your controller will send to a dimmer / fixture will basically have a value of anywhere between 0 and 255.

The 0-255 range is inherent in the actual structure of the DMX signal.

Controllers will be either from 0 to 10 or 0 to 100 because we can understand these ranges easier than 0 to 255.

If you actually look at the DMX output with a fader half way up, you will see an output of around the 127 - 128 mark.

Have a look at http://www.dmx512-online.com for one of the best explanations of DMX I have seen.

Cheerio!
