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 LED module, lights, string lights, etc.
• SZ200-DECODER(1CH) special design for single color LEDs, each universal DMX decoder takes up 1 DMX address.
• 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 normal single color dimmer, with 9 modes in total.
• In order to achieve synchronization of more LED lamps, signal repeater can be used.
• 1 channel for single color output, maximum current up to 25A, 300W.
• 2-year warranty.

Direction for use 
This product is in compliance with DMX512 protocol, compatible autoindex addressing and manual establishment address.
Each universal DMX decoder takes up 1 DMX address. It adopts 2 ways (autoindex addressing and code switch) to set up the address. When adopting the autoindex addressing, all switches are “off” status. When adopting the code switch to set up address, the 10th bit(FUN) is “off” status, and other 9 bits are  binary value code switch which are used to set up the DMX starting address code. The first bit is the lowest order bit, and the ninth is the highest order bit. That can set up 511 address codes. The DMX starting address code is equal to the sum of 1st to 9th bit. If move down one bit of code switch (“ON” set “1”), you can get the placevalue of this bit. If move up (set “0”), the placevalue 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 bit of code switch for “1”, and others for “0”, Then the placevalue’s sum of 1st to 9th bit 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: 1% brightness
Switch 2=ON: 10% brightness
Switch 3=ON: 25% brightness
Switch 4=ON: 50% brightness
Switch 5=ON: 75% brightness
Switch 6=ON: 90% brightness                    Figure 3 
Switch 7=ON: 100% brightness                           
Switch 8=ON: single color flash (8 levels of speeds are adjustable)
Switch 9=ON: single color breath(8 levels of speeds are adjustable) 

2. Speed setting of “single color flash” and “single color breath”: 

In test function, when switch 8=ON, is for single color flash. When switch 9=ON, is for single color breath. 8 levels of speeds are adjustable for each effect: 
1-7 switch OFF: 0 grades of speeds
