HX-DMXCM-3CH

DMX512 Decoder

HX-DMXCM-3CH, adopt the advanced micro control unit, it can receive the DMX-512 standard digital control signal which is internationally widely used. It changes the signal into PWM control signal to actuate the LED lamp. It can also connect the DMX digital master to change the light color or dynamic effect. In addition, when the decoder is not connected with the DMX master, it can be used as a synchronous controller. That is to say you can synchronously control number of decoders with LED lights.

Product Feature

 ● The DMXCM-3CH is 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.

 ● Except the manual-setting address by DIP switch.

 ● If no master, it also can be used as synchronized controller, all of them can synchronize work as a sync-work-system when connected by RJ45.

 ● When used alone, it also can be used as a normal RGB controller, with 9 modes in total.

 ● In order to achieve synchronization of more LED lamps, RGB amplifier can be used.

 ● There channels for RGB output, each allows a maximum current of 8A.

 ● 3-year warranty.

Direction for use 

This product is in compliance with DMX512 protocol, support manual establishment address by DIP switch.

Each universal DMX controller takes up 3 DMX addresses. When setting up the address via DIP switch, 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:

Decimals	1	2	3	4	5	6	7	8	9	10
Weightnumber	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.

Other function’s direction for use

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

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)

Figure 3

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

Switch 1=ON: 1 grade of speeds

Switch 2=ON: 2 grades of speeds

Switch 3=ON: 3 grades of speeds

Switch 4=ON: 4 grades of speeds

Switch 5=ON: 5 grades of speeds

Switch 6=ON: 6 grades of speeds

Switch 7=ON: 7 grades of speeds (maximum speed)

Figure 4

Like figure 4, when all switches are “ON” at the same time, the more value is taken as final. The state of decoder is gradual changing of test function. Its variable speed is 7. In addition, when signal 

indicator (green) blinks slowly, it runs the built-in program effectiveness of decoder. When the decoder receives the DMX signal, signal indicator will flash rapidly.
