be connected together in this manner! From the third device, please connect to power supply to
get power for the second link; when the voltage is over 200V~240V, only four devices may be
connected together in this manner! From the fifthly device, please connect to power supply to get
power for the second link.

7. DMX-512 CONNECTION WITH DMX TERMINATOR

For installations where the DMX cable has to run over a long distance or is in an electrically
noisy environment, such as in a discotheque, it is recommended to use a DMX terminator. This
helps in preventing corruption of the digital control signal caused by electrical noise. The DMX
terminator is an XLR plug with a 120 resistor connected between pins 2 and 3,which is then
plugged into the output (female) XLR socket of the last fixture in the chain. Please see
illustrations below.
