12CH-DMX512 Constant decoder Operation Instruction
Introduction:
Welcome to use the 12CH 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 ~ 12 output
channels; each channel can achieve 256 control levels. This constant decoder is used when DMX512 control equipment control general
LED lighting.

Decoder using the method
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 switches 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.
Decoder to use:
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 switches 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. 6,3,2 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
Schematic 1
Example2:
As the schematic 2, DMX512 start address is set to 388,
encoding the no. 2,3,6,8 switch dial to "1", others set to "0",
then the sum of the switch 1-8 code value is 4 + 128 + 256 = 388,
that is the DMX512 start address 388.
