There are plenty of videos on YouTube that explain DMX. There are also web sites with written explanations that you can find via Google.

DMX is not easy to get your head around but once you do, it's simple. Tedious but simple.
Lets say you have a scanner light that has a moving mirror and 3 colors R.G.B. Lets say that light is a 7ch DMX light. The 7 channels would be...
Ch. 1) X movement of mirror (side to side)
Ch. 2) Y movement of mirror (Up and down)
Ch.3) Red
Ch. 4) Green
Ch. 5) Blue
Ch.6) Shutter
Ch. 7) Dimmer
The 1st slider on your DMX controller will control where you want your light to point at. (Side to side)
The 2nd slider will control what height you want the light to be at. (Up down)
The 3rd slider will turn on Red and control how bright you want Red to be.
The 4th slider will turn on Green and control how bright you want Green to be.
The 5th slider will turn on Blue and control how bright you want Blue to be.
The 6th slider will control the lens being open (to allow light to show) and strobe.
the 7th slider will control the overall dimmer of the light.
Each channel has a value from 1 - 255
Example... Ch. 4 (Green) 1-40 = dim green, 41-150 = brighter green, 151-255 = brightest green.
Example... Ch. 6 (Shutter) 1-25 = closed shutter. 25-150 = completely open shutter, 151-200 = slow strobe, 201-235 = faster strobe, 236-255 = fastest strobe.
THESE ARE NOT ACTUAL NUMBERS BUT A REPRESENTATION!
To set up your DMX light to do what you want it to do, you have to set up scenes. Your scenes consist of many steps.
Example...
Step 1. Open shutter
Step 2. Choose your color
Step 3. point light where you want it to be
Step 4. Choose how bright you want the color to be
THIS IS ONE SCENE.
You will do this many times to create your scenes.
Hope this helps

To add to what djcity has said:
DMX controlled lighting fixtures are assigned by the starting address, i.e. if you want to assign the fixture to channel 1, the address would be 1 and then would occupy an address range from 1 on to, for example, 7. Therefore, your must fixture must be assigned to the next available address:
For example: if Fixture 1 is addressed to channel 1 and uses 16 channels, the next fixture can be addressed no lower than channel 17, and so on.
Also, some DJ lighting controllers such as the Elation DMX Operator use fixed preset DMX ranges for each fixture (I think it's 16 channels on the Operator): Fixture 1 would of course would be channel 1, however, fixture 2, no mater how many DMX channels the fixture uses, would still need to be assigned to channel 17 and you would only use the channels and faders on the console that you need.
Additional things to consider: it is OK to assign multiple fixtures to the same starting address. I often do this with LED pars, however it doesn't work as effectively with moving heads (I like to have individual control of each moving head for pan/tilt purposes), but is still possible. Do not ever overlap fixture addresses (i.e. Fixture 1 is addressed to channel 1 and uses 7 channels, Fixture 2 is addressed to channel 6). You will find 90% of the time that fixture 1 works however fixture 2 will not or will do incredibly odd things and could lead to damage to the fixture. DMX or DMX512 has a maximum of 512 channels (1 thru 511). This means if you ever address up into that range your last fixture must end on or before 511.
Fixtures that address using dip switches are addressed in binary. Each switch 1-9 representing a binary digit: 1, 2, 4, 8, 16, 32, 64, 128, 256. For example: let's say that you want to address you fixture to channel 100: this would be accomplished by adding 64+32+4 or 001001100. There are many iOS and Android apps like DMXcalc that assist in the addressing this type of fixture.
Finally, I wanted to mention for those looking for a more advanced lighting controller without spending a ton of money there is Chamsys MagicQ. They make entertaiment consoles and controllers, as well as giving away their console software for free use on Mac/PC/Linux and can output DMX using a variety of USB/DMX interfaces (I use the ENTTEC USB/DMX Pro). Essentially you get a virtual Whole Hog II lighting console for the cost of a DMX interface. It is, however complicated, but like most things can be learned easily.
