and this is how DMX Works imagine your light needs 1 Channel (a milk bottle) and when that milk bottles empty (the values at 0) you get no light output but slowly as you fill the milk bottle with milk (increasing the value) your light gets brighter and brighter until your bottle has got 255 litres of milk (the max), need it dimmer? Then pour some of that milk out! every litre is activating a switch that does something on your light and some lights don't mind having a value within a range for example in the manual it will say 230 - 255 turns the light green so when you fill that bottle up once it reaches 230 and up until 255 your light will stay green! | and this is how DMX Works imagine your light needs 1 Channel (a milk bottle) and when that milk bottles empty (the values at 0) you get no light output but slowly as you fill the milk bottle with milk (increasing the value) your light gets brighter and brighter until your bottle has got 255 litres of milk (the max), need it dimmer?

+ | |||
+ | So to Summarise : | ||
+ | |||
+ | * Imagine the 512 Channels of DMX as 512 Milk Bottles. | ||
+ | * Each one can contain up to 255 units of milk (The Value). | ||
+ | * For every unit of milk added to the bottle it can make your light do different things or if you fill it up between xxx units and xxx units your light may activate one function like a colour change. | ||
+ | |||
+ | From now on we'll talk about these imaginary milk bottles as Channels and the contents of the bottles as Values. | ||
+ | |||
+ | So how does your light know what channels are assigned to it? | ||
+ | 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 [[: | ||
+ | |||
+ | 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 [[: | ||
+ | |||
+ | So again to Summarise : | ||
+ | |||
+ | * Your light needs a place to live along the street of 512 channels | ||
+ | * Your manual will tell you how many channels it needs to operate | ||
+ | * When you set the address your light will automatically know the next amount of channels are for it so that's in our example 1 (The adddress) and 5 more channels making 6 Channels altogether! | ||
+ | |||
+ | So if it's that simple then what's all this creating fixtures and profiles for say [[: | ||
+ | |||
+ | Basically adjusting the values manually on older [[: | ||
+ | |||
+ | Your Software is simply raising values up and down on different channels simple! | ||
+ | |||
+ | But to make things much faster it has ways to do things to make your life easier take for example your light has 20 different colours your software doesn' | ||
+ | |||
+ | So to recap : | ||
+ | |||
+ | * DMX Software and advanced ' | ||
+ | * But they don't know what lights are connected and how it that light operates | ||
+ | * Fixture profiles are your way of telling the software/ | ||
