In the Controller mode, at the last fixture in the chain, the DMX output has to be connected with a DMX terminator. This prevents
electrical noise from disturbing and corrupting the DMX control signals.
The DMX terminator is simply an XLR connector with a 120

(ohm) resistor connected across pins 2 and 3, which is then plugged
into the output socket on the last projector in the chain.The connections are illustrated below

DMX STARTADDRESS
Each projector must be given a DMX start address so that the correct projector responds to the correct control signals. This DMX start
address is the channel number from which the projector starts to “listen” to the digital control information being sent out from the
controller. The projector has 3 DMX modes. There are short mode ,standard mode and extended mode. For example standard mode
has 52
c hannels, so set the No. 1 projector’s address 001, No. 2 projector’s address 053, No. 3 projector’s address 105, No. 4
projector’s address157, and so on.
