24CH DMX512 Decoder

Detailed Product Description

 

Summarization

  The decoder adopt the advanced micro-computer control technology and converted the DMX512 digital signal widely used in international to the analog control signal. 1~24 channels output for option and each channel able to achieve 256 gradations of controlling, and also it can be used as the connector of PC digital light controller and analog light modulator. It is mainly used for the controlling of buildings & lights applied LED.

• Address code setting on/off: Please see the operating instruction next page. 
• Power input interface: DC12~25V input,supplied power with the decoder and the lamps it takes.
• Drive output interface: Common in anode-V+ and with 8pcs of V+ interface & 24pcs of R, G, B output interface. Not only does it apply to the various of LED module in full-color & mono color, but also it can self-trimming the output current based on the load of LED module. 

 

Remark:

Connect the anode and RGB wire of common anode RGB module to the output interface of decoder directly; Connect the anode wire of single-color module to V+ on decoder, and connect the cathode wire to one of RGB pin according to the LED's color; Connect several colors single-color module to one decoder, please connect their anode wires to V+ pin on decoder.

 

Direction for use

1. Connecting of DMX-512 Signal Cable:

DMX signal cable used the CAT-5 cable,and DMX signal tells positive(+) from negative (-). While welding the DMX signal cable plug, there must pay much attention to know positive (+) from negative (-), and then connect the DMX512 signal cable with the corresponding input interface of DMX512 decoder correctly.

1. DMX-512 address code set:

DIP switch of DMX512 decoder is with the function of writting the binary system and reading the DMX512 address code. DMX512 decoder is a decoder with 24 channels, When it is on-line job, the second DMX512 decoder should be set the address code as the 25th channel. The 10th bit is TERM and will be the terminal while it is off.(Only used for the signals circuit setting).The bits from1 to 9 of DIP switch are as the key of writing DMX address code, 1 is LSB and 9 is MSB; total 512 address codes. The initial address code is the DMX signal received by the No.1 channel of decoder, Calculational formula: [ Sum of 1~9 bits of DIP switch ] = DMX initial address code Set the n(th) bit of DIP switch up(set to“1”)to get the value of such bit; Set the n(th) bit of the DIP switch down “0”),so the value of this bit is 0.

Note: The 10th bit is the terminal.

Value of each DIP:

DIP	1	2	3	4	5	6	7	8	9
Value	1	2	4	8	16	32	64	128	256

 

Example 2: Set to 226

Set the 8th,7th,6th,1st bit to “1”,others set to“0”,then the sum of the 1~9 is 128+64+32+2,is the start address 226.

That is: [ 128 + 64 + 32 + 2 ] = 226
