DMX-512 connection with DMX terminator
For installations where has it has too much lines or lights environment it is recommended to use a DMX
terminator. This helps in preventing corruption of the digital control signal by electrical noise. The DMX
terminator is simply an XLR plug with a 120 Ω resistor connected between pins 2 and 3,which is then plugged
into the output XLR socket of the last fixture in the chain.
5. DMX address setting
Each fixture must set a specific starting address. When receiving signal transmission, fixture will receive
channel control signals which from the starting address.
According to different requirements or easy to use, the user can set many value fixtures to the same address,
also can set up a separate address for every device.
If you set the same address,all the devices will receive from DMX channels signal. All connecting fixtures are
jointly controlled, controller can't separate control a device.
If you set a different address, each device will be separate from its particular set the starting address and begin
accepting DMX512 control signal, so that more convenient separate control one device. Using this method
must be based on channel quantity of device to determine a starting address.
This led moving head light has 23 channels.you should set the starting address of the first unit to 1, the second
unit to 24(23 + 1), the third unit to 47 (24+ 23), and so on.
