3CH 4CH RGB RGBW LED DMX Decoder
This DMX512 decoder adopts the advanced micro control unit, It can receive the DMX-512 standard digital control signal which is internationally widely used. It changes the signal PWM control signal to actuate the LED lamp. It can also connect the DMX digital console to change the light or each dynamic effect. In addition, when the decoder is not connected with the DMX console, it can be used as a synchronous controller. That is to say you can Synchronously control number of decoders and LED lights.
This product is in compliance with DMX512 protocol, and compatible auto-index addressing and manual establishment address.
1. Each universal DMX controller takes up 4 DMX addresses. It adopts 2 ways 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)
