3CH DMX512 Constant Decoder Instruction
Welcome to use the 3CH constant decoder, which take advantage of advanced microelectronic control technology. This technology changes the international fashion DMX512/1990 standard digital control signals into analog control signals. There are 1~3 output channels, each channel can achieve 256 control levels. This constant decoder is used when DMX512 control equipment control general LED lighting.
Basic functions
***There are 3 output channels, can connect with single or RGB lamps.
***0~100% dimming output, each channel 256 gray levels.
***International standard DMX512 input protocol, address code set by DIP switches.
***Wide input voltage DC12V-DC24V.
***Each occupied by 3 DMX address.

How to use the 3CH DMX512 LED Decoder
The item have DMX512 function, can be used in serval online.
There are DMX512 signal mode and Automatic mode.
1.DMX MODE
In this mode, you can control the LED decoder with DMX512 console or PC DMX512 console.
Note: FUN=OFF (the tenth code switch up) means to accept DMX512 signal mode.
The first DMX address setting:
The decoder set the address bit by coding switch, of which 1-9 is for setting the start address of the Binary numeric code switch of DMX512, the first one is the lowest position, the ninth one is the highest.
Bit of address code can be set to 512.
DMX512 start address code is the sum of switch 1-9, at the same time turn downside of the code switch (ON set to"1" ), then the value of the bit can be gotten; coding switch up (set to "0" ), the value of the bit is 0.
Example 1:
As the following schematic 1, DMX512 start address is set to 38, encoding the No.2,3,6 position on switch dial to "1", others set to "0", then the sum of the switch 1-9 code value is 32+4+2, that is the DMX512 start address 38.
Example 2:
As the schematic 2, DMX512 start address is set to 388, encoding the no.3,8,9 switch dial to "1", others set to "0", then the sum of the switch 1-9 code value is 4+128+256=388.
2. AUTOMATIC MODE
In this mode, the LED decoder will run automatically.
Note: It will be automatic operation mode when the No.10 is turned down.
