While this might sound like you’re headed out to do a bunch of math – never fear! Your console or software likely will handle all the number-crunching for you in the “Patch” screen. If you don’t do this, you’ll be trying to control one light, and another one may start doing something you did not expect! So, if you have a 3-channel fixture starting at channel 28, the next open address would be address 31. However, if it is a multiple channel fixture, like an LED or moving light, you need to be sure and leave the total amount of channels the fixture takes open before patching the next fixture. This would give you the first on address 1, the second on 2, etc. If you have a one-channel device, like a single-colored light that simply turns on and off, then you can address the fixtures one right after another. Often, this is referred to as the “start address” since it is the first address that a given fixture uses. One of the first things you’ll have to do when you begin lighting is to address your fixtures.Īn address is the location in the 512-channel universe that the DMX device begins. This is one of the biggest advantages of DMX and why it’s the standard that we use to control stage lighting today. DMX-controlled lights from any manufacturer can be controlled by any DMX console – even if that console is made by someone else. This means that you plug the initial DMX cable into the first fixture, the “OUT” of the first fixture into the second fixture, etc, up to 32 fixtures maximum – more on that below.ĭMX is not manufacturer specific. This is pretty incredible if you remember some old analog control systems where you had 1 pair of wires for each channel of the console!ĭata is sent down this line via pulses of electricity from a lighting console, into your fixtures that are usually “daisy-chained” together. This may be a color like red, green or blue, and intensity, strobe, pan/tilt or other attributes. This means that 512 channels are controlled digitally through 1 data cable.Ī channel is a set of 255 steps that are assigned to control attributes in each light.
Let’s dive in! What is DMX 512?ĭMX512 stands for digital multiple x 512.

Then, we dive deeper and show you how to do some deeper level wiring, splitting and converting. On the other hand, if you don’t follow the rules, you’ll run into some serious headaches and trouble! Below, I cover the basic terms and information that you need to begin with DMX. When you follow the rules, your gear will work great and be a blessing to you. Whether you’re 100% new to lighting or have been around the block, it’s super-important to have an understanding of DMX so that you can set your lights up correctly and troubleshoot any problems that come up.ĭMX can be your best friend or your worst enemy. In lighting, DMX is everywhere, and it is how our lights get information on what to do from our consoles or software. When you’re beginning with lighting, it’s not going to be long before you have questions about DMX.
