Product Feature 

• As a constant voltage decoder, accept international popular DMX512 standard digital control signal, convert it to the PWM signal to drive LED lamps, applicable to a variety of constant voltage LED lamps, such as RGB LED module, lights, string lights, etc.
• DMX decoder can be controlled by DMX master, and the decoder can connect the signal line to continue to expand the channels up to 512, eventually be able to achieve more change in effect.
• When used alone, it also can be used as a RGB controller, with 9 modes in total, can be chosen by the DIP switch.
• In order to achieve synchronization of more LED lamps, RGB amplifier can be used.
• There channels for RGB output, maximum current of 6A/CH.
• 2-year warranty.

Direction for use 
This product is in compliance with DMX512 protocol, compatible autoindex addressing and manual establishment address. 
Each DMX512 decoder occupies 3 DMX addresses, adopt DIP switch to set up address: When set up the address via DIP switch, the 10th DIP switch bit is “off” status, and other 9 DIP switch(1-9)  bits are binary value code switch, which are used to set up the DMX starting address code. The first DIP switch’s bit is the lowest order bit, and the ninth’s is the highest order bit. That can set up 511 address codes. The DMX starting address code = (equal to ) sum of 1st to 9^th bit. If move down the DIP switch (“ON” set as “1”), you can get the Bit value of this DIP switch. If move up (set as “0”), the bit value is 0. For example: if you want to set up DMX starting address code for 73, you should move down the 7th, 4th, and 1st DIP switch as “1”, and others as “0”, Then the bit value sum of 1st to 9th is 64+8+1. That is to say, the DMX512 starting address code is 73. (The correspondence dials code position is as follows) 
To choose the channel from the Dial in-line Package (DIP) Switch: 

Number	1	2	3	4	5	6	7	8	9	10
Weight number	1	2	4	8	16	32	64	128	256	FUN

1. Example 1:

   Like figure 1, to set up the DMX starting address code for 37, should move down the 6th, 3th, 1st bit for “1”, others for “0”. Then the placevalue’s sum of 1st to 9th bit is 32+4+1, as is for 37. 

Figure 1 

2. Example 2: 

Like figure 2, to set up the DMX starting address code for 328, should move down the 9th, 7th, 4th bit for “1”, others for “0”. Then the placevalue’s sum of 1st to 9th bit is 256+64+8, as is for 328.

The function outside of the DMX 

1. Control with DIP switch 

1. Test function:

 The DIP switch’s 10th bit is “FUN”, for built-in function key. When “FUN”=”OFF”, is for DMX decoder function. This is used to adopt DMX signal. When “FUN”=”ON”, the test function like figure 3:
1-9 switch OFF: black
Switch 1=ON: red
Switch 2=ON: green
Switch 3=ON: blue
Switch 4=ON: yellow
Switch 5=ON: purple
Switch 6=ON: cyan
Switch 7=ON: white                                              Figure 3
Switch 8=ON: Seven-color jumpy changing (8 grades of speeds are available)
Switch 9=ON: All-color gradual changing (8 grades of speeds are available) 

2. Speed choice of jumpy changing and gradual changing’s effect: 

In test function, when switch 8=ON, is for seven-color jumpy changing effect. When switch 9=ON, is for seven-color gradual changing effect. 8 grades of speeds are available for each effect:
1-7 switch OFF: 0 grades of speeds
