Interface Specifications

Direction for use

This product is in compliance with DMX512 protocol, compatible auto index addressing and manual establishment address.

Each universal DMX controller takes up 3 DMX addresses. It adopts 2 ways (auto index addressing and code switch) to set up the address. When adopting the auto index 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 place value of this bit. If move up (set "0"), the place value 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 place value'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:

Example:

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 place value's sum of 1st to 9th bit is 32+4+1, as is for 37.
