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.

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
Example 2:
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.

Plan two:PC DMX512 Console+USD DMX controller+12CH DMX decoder
Installation Notes:
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:
FAQ:
1. Input voltage is normal?
Ensure input voltage DC 5-24V, cathode connected DC +, negative pole DC-. When the normal power supply, the controller red indicator light on.
2. The DMX decoder controller needs DMX master control.
The controller is a DMX decoder. You must use DMX master control it. DMX master such as: USB DMX master, DMX console.
3. The decoder is not controlled?
(1) Ensure that the decoder signal line connected to right. Negative signal decoder corresponding master negative, Positive signal decoder corresponding to the master positive, GND decoder corresponding to the master GND.
(2) Ensure that the decoder is DMX mode, DIP switch tenth position must be zero.
4. How adjustment whether the decoder received DMX signal?
The decoder of the green indicator light flashes slowly or does not flash when no signal is received, indicating that the received signal when the green indicator light quick flashes.
