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 9 channels.you should set the starting address of the first unit to 1, the
second unit to 10(9 + 1), the third unit to 19 (10+ 9), and so on.
