How to use DMX512 pixel LEDs with pixel LED controllers

DMX512 Protocol

Digital Multiplex is a communication protocol used to remotely control lighting dimmers and intelligent devices. DMX is an  asynchronous serial digital data protocol .  It’s designed to provide a common communications standard between these lighting devices . So that deferent devises from different manufactures can work together.  

The number 512 after the DMX refers to the number of control channels used on one network segment of devices.  In a simple dimming system, one channel controls the intensity of one dimmer.  A single intelligent device may require several channels to control its various parameters .

The DMX 512 protocol is based on the Standard 485 or RS-485 (EIA/TIA-485 standard), which uses asynchronous, differential data transmission.  This standard supports 32 devices on one network at a distance of up to 4000 feet.  One device functions as the master (the DMX controller) on a network, while the rest function as slaves (dimmers, intelligent fixtures, etc.).  Only the master transmits over the network, and all slaves receive the same data.

Creating Pixel LED Using TM1812

TM1812 is a 12 output RGB LED drive IC , which means single TM1812 IC can drive 4 RGB LEDs.This IC consists of data latch , signal reshape and high voltage regulator circuits. It can be used for outdoor large-screen and color dot-matrix control applications.Since it can control 4 RGB LEDs  ,this IC is most suitable for designing pixel LED strips .
