DMX512 ADDRESSING
WHEN ADDRESSING YOUR FIXTURES FOLLOW THE STARTING ADDRESS IN
THIS BOOK NOT THE ADDRESSING FOUND IN YOUR FIXTURE MANUAL
DMX 512 is a type of protocol that sends out up to 512 multiplex
channels at once down a common cable. Each channels has a
value from 0 to 255. You set the address for each receiver(fixture) by
using Dip switches or some type of digital readout
While DMX 512 is the standard used to control lighting, at this time,
there are some differences you should know about. One is pin con-
figuration. The DATA + And DATA- are reversed. This can be corrected
by using the reversal switch on the DMX Operator. If you have some
fixtures from each polarity use adapter Z-DMXADAPT between the
fixtures.
Each Dip switch has an ADDRESS based on binary code.
Dip switch
#1 #2 #3 #4 #5 #6 #7 #8 #9
Value 1 2 4 8 16 32 64 128 256
YOU SELECT THE ADDRESS WANTED BY ADDING THE TOTAL OF DIP
SWITCHES ON.
Dip switch #10 is not used with DMX but normally to select some
Function ie: Master / Slave, Sound Activation or to receive DMX
Control.
