DIP Switch Value
1 001
This decoder adopts Dip switch to set the address,
the Dip switches from 1 to 9 are a kind of binary
2 002
value coding switches which used for setting DMX512
3 004
initial address code, the correlative bits is the 1-9
4 008
bits of the DIP switch, the 1 bit is LSC, the 9 bit
5 016 MSC , 511 addresses totally.
DMX512 initial address is the total amount of the
6 032
Dip switches' number from 1 to 9, press Dip switch
7 064
downward (ON: at position "1"), user can get the
number of its position, if pressing upward (at
8 128
position "0"), the number of its position is 0.
9 256
Example 1: Set initial address to 37
st rd th
Set the 1 , 3 , 6 , bit of the DIP switch downward to "1"the rest to "0"
(picture 2), the summation from 1 to 9 is 1+4+ 32, so the DMX512 initial address
code is 37.
