Summarization

The DMX-SPI decoder adopts the advanced micro control unit, it receives standard DMX-512 digital control signal that is widely used in the international and transformers it into SPI signal to drive LED, it supports 10 kinds of different model of lights, at the same time the port of DMX signal has lightning protection measures; you could connect the DMX decoder with DMX digital console to achieve dimming or various changes in procedures. Not connected with DMX console, you can choose select the built-in 35 kinds of default patterns through the modle button, the default points is 512.

Direction for use

1.      parameters settings of decoder

You can modify the light type that decoder supports through the DIP switch. The decoder can support 10 kinds of SPI strips in market. As follows:

If there are 2 signal lines, then you need to connect the ground wire, clock line, data line with GND、CLK、DATA; if it is 1 signal line, then just need to connect the ground wire, data line with GND、DATA.

Remark: if the V+ voltage of strip is the same with controller input voltage, then it can directly connect with the controller V+; if not, you need to connect another power supply.

Since the specifications of light in the market are different, the sequence of RGB may be different, the sequence of some lights is RGB, some sequence is RBG, GRB and so on, so the  DIP switch provides modification of RGB sequence.

DIP switch is shown as below:

IC type: selection of light type. The accumulation of first four DIP is 1*1+2*0+4*0+8*0=1, lookup the table, you can find it is LPD6803.

LED Sequence: selection of RGB sequence. DIP 5 above is pressed, it indicates that the color sequence of light is RGB.

Remark: if the accumulation of IC type is more than 10, such as 12, 14, the default is 10, that is P9813; when LED sequence, there are two or more DIP are press, such as 5, 7, 9 are pressed simultaneously, default it will take the largest value 9, that is BRG.

2. Indicator description: the signal lights up indicates that it detectes button is pressed, the signal is off indicates there is not button pressed.

3. Buttons can only be used when the controller is not connected with DMX signal, when controller is connected with DMX console, the mode of console is priority, and the buttons will not have any effect. 

Mode changes are as the following table:
