SPI-DMX512 LED Decoder
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 transformes 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.

Controller External Dimension:
Interface of DMX signal adopts the 6PIN green terminal interface,
wiring is as follows
DMX IN: input interface of DMX signal, D+ should be connected with
positive of signal, D- connected with negative of signal, Gnd
connected with ground.
DMX OUT: output interface of DMX signal, D+ should be connected
with positive of signal, D- connected with negative of signal, Gnd
connected with ground.
Power and load output adopts the 6PIN green terminal, wiring is as
POWER: input interface of power, V+ should be connected with
positive of power, V- connected with
negative of power, the range of supply voltage is DC5-24V
OUT PUT: load output interface, V+ should be connected with the
positive of light, GND connected with negative, DATA connected with
data interface of light, CLK connected with clock interface of
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.
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
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
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
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
Single power connect single signal line strip condition: if the V+
voltage of strip is the same with controller input voltage,and the
light signal is single then it can directly connect with the
