How To Wire With DMX512 Digital Led Strip

When Editting Address And Controlling

DMX512 protocol was first developed by USITT (American Theatre Technology Association) to control dimmer from console with standard digital interface. DMX512 surpasses the analog system, but it can not completely replace the analog system. 
    The simplicity, reliability and flexibility of DMX512 make it is first choice of protocol when funds permit. DMX512 is still a new field of science, which is based on rules.DMX512 console control analog led strip light drawing. 

At present, A type of led strip called DMX512 digital led strip is designed based on DMX512 protocol. Its appearance is similar to the addressable led strip controlled by SPI signal. But the designer implants the DMX512 decoding module in the control chip, And the console can directly control the led strip lights. The drawing as below:

Greeled DMX512 digital led strips have two different types: single-line and double-line types.
Single-line DMX512 addressable led strips are controlled by "A" signal of console. These led strips have no DMX512 decoding module in chips. So we have to add external mini DMX512 to RS485 decoder at Inputting of led strip.
Double line DMX512 addressable led strip are controlled by AB differential signal. Then Stardard DMX console can control it directly. 
Before lighting on led strip, We must write address code in single-line/Double-line DMX512 digital led strip‘s chip by DMX address editor.
