1.How to understand DMX?
DMX stands for Digital Multiplex interface.
Each universe 512 channels and is wired using 3-pins or 5-pins.
So it is sometimes called DMX 512, because it can be used to control up to 512 channels. To better understand the word channel, think of a DMX "Channel" as a "Color", so if you have an RGB light this light would use 3 "Channels" or "Colors". You can control up to 170 RGB Lights in a single DMX universe or up to 512 single color lights in one DMX universe. Each fixture is specifically addressed within the 512 universe using a DMX Decoder/Driver, and you program your light scenes according to the DMX address that you assigned to each fixture.
2. DMX code is needed for each light or color
The number of different fixtures or groups of fixtures that you would like individual control over is important because each section is going to need a specialized DMX address through a DMX Decoder/Driver unit. It is also important to know how many channels or colors that each section is going to need in order to be controlled. For example if you would like to control a single color LED light then you will need a single channel DMX Decoder/Driver. For an RGB fixture you will need 3 channels in order to control all 3 colors, so a 3 channel DMX Decoder/Driver will be necessary. If you are using an RGBW fixture then you will need a 4 channel driver/decoder and so on.
3.Where to buy DMX controller
It is important to figure out the number of fixtures that you would like to control as well as the total number of DMX Channels you will be using before purchasing a DMX Controller as some controllers are limited in the amount of DMX Channels they can control as well as their memory capacity. Our U6 DMX Controller can control up to 60 DMX Channels with limited memory, while our Stick Controller can control 2 full DMX Universes (1024 Channels) with unlimited memory. This is why it is important to know what you want to do with your lights and how many DMX Channels you will be using before you purchase a DMX Controller.
