Welcome to use the12CH 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.

The first DMX address setting:
The decoder set the address bit by coding switch, of which 1-8 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 255.
DMX512 start address code is the sum of switches 1-8, 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 37, encoding the No. 6,3,1 position on switch dial to "1", others set to "0", then the sum of the switch 1-8 code value is 32 + 4 + 1, that is the DMX512 start address 37
Schematic 1
Example 2:
As the schematic 2, DMX512 start address is set to 166, 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 2 + 128 + 256 = 388, that is the DMX512 start address 166.
Schematic 2
1 This kind of controller works only under DC5V-24V, which is provided by the matched controllable main power, or else the controller will be damaged.
2 The UTP wire is connected hand in hand to make the cable, when two or more controller connected.
3 The power supply should be off when connecting the electric wires, and it can be turned on till making sure the wires are connected correctly and the indicator of main power in red is lighting.
4 Controller should work under the environment of adequately ventilated, dry, not corroded, no flammable gas and rust.
5 Please check the wires connection regularly so that the wires of aged, rust-eaten, and damaged insulation spacer can be replaced timely
Simple troubleshooting and maintenance:
Symptom |
Reason Analysis |
Solution |
NO lighting |
1 No power 2 Wrong connection of wire 3 Power protection setting |
1 check power supply 2 check wire connection 3 check power failure, power on again |
Red indication light is on, green indication light not flash |
Didn’t make dip switch or dip switch is not in correct |
Follow up the instruction to reset dip switch |
The Light color is not show in correctly |
1.RGB LED is not connection correctly 2.Dip switch is not in correct place |
1 Re-connect the RGB and wire 2 Reset dip switch |
Can’t be synchronization |
1 The RJ45 cable is not connected or wrong connection 2 master and slave controller setting failure,The slaver is set dip switch effects |
1 re-connect the RJ cable 2 reset master and slave controller to ensure only one master |
Led brightness is different at beginning and end |
1, Output line is too long 2, The diameter of wire is too thin 3, Overload working |
1, Use annular electric supply or shorten circuit 2, Calculate electrical current, change strong wire 3, Change power or increase controller |
