The invention provides an intelligent RDM coder which realizes the coder scheme that the size is small, additional installation and debugging are convenient and networking control can be achieved. Theintelligent RDM coder comprises a shell, a built-in circuit, a plurality of buttons and connecting terminals, wherein the buttons and the connecting terminals are arranged on the shell. The built-incircuit comprises a power supply module, a processor module, a WIFI module and a DMX bus module, wherein the WIFI module and the DMX bus module are connected with the processor module. The processor module comprises an MCU, the MCU is connected with the buttons and is connected with upper control equipment through the WIFI module, and the buttons at least comprise a setting button. The connectingterminals comprise the DC+ terminal andthe DC-terminal and further comprises theD+ terminal, the D-terminal and the GND terminal which areconnected with a DMX bus in a hanging mode. The power supply module is provided with a DC power supply interface. According to the intelligent RDM coder, construction is convenient, operation is easy, compatibility is high, most products with the RDM function onthe market can be controlled and subjected to parameter browsing and setting, and the products can be controlled after being connected with a handheld terminal; and the light dimming modes are diversified, and single-address dimming, group address dimming and broadcast dimming can be carried out.
