Welcome to use the 30CH constant decoder, which take advantage of advanced microelectronic control technology. This technology changes the international fashion DMX512/1990 standard digital control signals into analog control signals.There are 1 ~ 30 output channels; each channel can achieve 256 control levels. This constant decoder is used when DMX512 control equipment control general LED lighting.

Basic functions:
There are 30 output channels, can connect with single or

RGB lamps
0-100% dimming output, each channel 256 gray levels
International standard DMX512 input protocol, address

code set by DIP switches;
Wide voltage DC input DC9V ~ DC24V;
Each occupied by 30 DMX address.
The decoder comes with 16 kinds of test patterns, 16

levels for rate of change
 
Decoder to use:

Note: FUN = OFF (the tenth code switch up) means to

accept DMX512 signal mode
The first DMX address setting:
The decoder set the address bit by coding switch, of

which 1-9 is for setting the start address of the Binary

numeric code switch of DMX512, the first one is the

lowest position,
the ninth one is the highestBit of address code can be

set to 255.
DMX512 start address code is the sum of switches 1-9, at

the same time turn downside of the code switch (ON set

to "1"), then the value of the bit can be gotten; coding

switch
up (set to "0"), the value of the bit is 0.

Example 1:
As the following Schematic 1, DMX512 start address is

set to 38, encoding the No. 6,3,2 position on switch

dial to "1", others set to "0", then the sum of the

switch 1-9 code value is
32 + 4 + 2, that is the DMX512 start address 38

 

Schematic 1

Example 2:

As the schematic 2, DMX512 start address is set to 388,

encoding the no. 2,3,6,8 switch dial to "1", others set

to "0",, then the sum of the switch 1-8 code value is 4

+ 128 + 256 = 388,
that is the DMX512 start address 388.

There are three kinds of using method:

one:
 

 

two:

 

three:
 
if you want to 5 v input, the connection is as follows :

if you need to connect two power supply, the connection is as follows:

 

Installation Notes:
1 This kind of controller works only under DC9V-24V,

which is provided by the matched controllable main

power, or else the controller will be damaged.
2 The UTP wire is connected hand in hand to make the

cable, when two or more controller connected.
3 The power supply should be off when connecting the

electric wires, and it can be turned on till making sure

the wires are connected correctly and the indicator of

main power in red is lighting.
4 Controller should work under the environment of

adequately ventilated, dry, not corroded, no flammable

gas and rust.
5   Please check the wires connection regularly so that

the wires of aged, rust-eaten, and damaged insulation

spacer can be replaced timely
Simple troubleshooting and maintenance:

Symptom	Reason Analysis	Solution
NO lighting	1,No power 2,Wrong connection of wire 3,Power protection setting	1,check power supply 2,check wire connection 3,check power failure, power on again
Red indication light is on, green indication light not flash	Didn’t make dip switch or dip switch is not in correct	Follow up the instruction to reset dip switch
The Light color is not show in correctly	1.RGB LED is not connection correctly 2.Dip switch is not in correct place	1,   Re-connect the RGB and wire 2,   Reset dip switch
Can’t be synchronization	1,The RJ45 cable is not connected or wrong connection 2,master and slave controller setting failure,The slaver is set dip switch effects	1,re-connect the RJ cable 2,reset master and slave controller to ensure only one master
Led brightness is different at beginning and end	1, Output line is too long 2, The diameter of wire is too thin 3, Overload working	1,   Use annular electric supply or shorten circuit 2,   Calculate electrical current, change strong wire 3,   Change power or increase controller
