ABSTRACT:
A DMX512 signal source distributor and a loader for a plurality of LED controllers can control LED devices such as an LED board. The DMX512 signal source distributor includes a UART, an MCU connecting to a memory, and a DMX512 encoder chip connecting to a memory. The UART is connected with a personal computer and the MCU, and the UART also can provide a wireless transmission function. The DMX512 encoder chip is further connected to several differential drivers. A loader includes a UART, a MCU connecting to a memory, a keyboard, and an LCM. The signal controllers are controlled by the DMX512 signal source distributor and the loader. The LED controllers can be modulized, which not only can work alone, but also can be combined into a complex system.
