DMX Channel Count

[Ed Slonka Jr]

Just need to get this straight in my head. If you have a 2801 pixel string with 50
nodes on the string is this 50 dmx channels or 150 dmx channels because of the RGB?

I keep confusing myself!

Thanks, Ed

A pixel is 3 channels as it is Red, Green and Blue to each LED light. So a 50 pixel string will be 150 channels

Thanks Eddy, I thought that and then I started to like I said.... confuse myself!

Think like this:

RGB Pixels = 3 channels per node.

Dumb RGB = 3 channels per string.

Thanks Slite!

does this also apply to strings of led/incandescent lights that are the same colour. If so how many lights-bulbs are counted as channel. ie 20 metre string of warm white (for example) is this equivalent to 3 channels.
Eg DMX universe has 512 channels does this mean i could run 170 strings (length ????)

A single string like the one you reference to would be considered as 1 channel as thats all that it will use. Now if that same string had 2 sections and you controlled each section individually then that would be considered as 2 channels because thats how many you would have had to use..

ok thanks for that eddy, much clearer now

Hi,

First time posting. I'm new to this and just to see if I have this right, if I have 8 strings of 50 pixels (400 pixels total), and I want to control each bulb, that 1200 channels which would equate to 3 universes?

Thanks,
Fran

8 strings x 50 pixels = 400 pixels

each pixel will use up 3 channels, one for Red, one for green and one for Blue

so 400 pixels x 3 = 1200 channels


So yes 1200 channels which you will need 3 universes to run as each universe is 510 channels when using pixels.

Thank you! Glad to know that I finally got unconfused...
