 Hello and welcome to The DMX Wiki, Hello and welcome to The DMX Wiki,

 Each one can contain some milk but only so much and that limit is '255' so the milk bottles in front of you represent the 512 Channels in DMX but what does that '255' refer to? Well that's the maximum 'Value' of the amount of milk your bottle can hold.  Each one can contain some milk but only so much and that limit is '255' so the milk bottles in front of you represent the 512 Channels in DMX but what does that '255' refer to?

 Well this is what we call Addressing in DMX every channel is fixed so imagine 512 milk bottles lined up in a row every single one has a number on it in order 1 to 512, rather like a street with houses that all have an address. Well this is what we call Addressing in DMX every channel is fixed so imagine 512 milk bottles lined up in a row every single one has a number on it in order 1 to 512, rather like a street with houses that all have an address.
  
-Your light needs an address so when your DMX Control Software or Hardware sets the values of a channel your light will respond (fills up a bottle and your light responds to that amount depending on how its programmed).+Your light needs an [[:dmx_basics:dmx_addresses|address]] so when your DMX Control Software or Hardware sets the values of a channel your light will respond (fills up a bottle and your light responds to that amount depending on how its programmed).
  
 Your light will say in the manual it needs a certain amount of channels to operate for example let's say 6 but how does your light know which 6 channels out of the 512 it needs? Your light will say in the manual it needs a certain amount of channels to operate for example let's say 6 but how does your light know which 6 channels out of the 512 it needs?
-It needs to know where its main address is within the 512 that's what you set on the light either with the display or using [[dmx_definitions:dip_switches|]]. Imagine your light being a property developer it's address is the first house it buys but it needs 6 to work so it buys 5 more next door to it's first, YOU decide the main house it buys by setting it's address then if its a 6 channel fixture it will automatically own the next 5 houses!+It needs to know where its main address is within the 512 that's what you set on the light either with the display or using [[:dmx_definitions:dip_switches|]].

-Basically adjusting the values manually on older DMX hardware involved a simple slider you tell that slider what channel it is then as you raise the slider up its raising the value of that channel up to 255 (or filling that milk bottle!) it's that simple but you needed to know what value did what to make it faster to program, DMX Software can do this by presenting you with Graphical buttons, sliders, positioning controls and colour pickers etc etc this makes your work flow so much easier but guess what? Every DMX Unit is different, How does your DMX Software know that to raise the 2nd channel (i.e. the second house it owns) to 255 makes your light go green or how does it even know if your light can even go green? That's where building profiles comes in...+Basically adjusting the values manually on older [[:dmx_hardware|DMX hardware]] involved a simple slider you tell that slider what channel it is then as you raise the slider up its raising the value of that channel up to 255 (or filling that milk bottle!) it's that simple but you needed to know what value did what to make it faster to program, [[:dmx_control_software:|DMX Software]] can do this by presenting you with Graphical buttons, sliders, positioning controls and colour pickers etc etc this makes your work flow so much easier but guess what?
