Power/Data cable:
In order to guarantee a reliable operation, we strongly recommend the use of our Rainbow
Power/Data cable. This XLR4 pole cable contains two lines á 0,38 sqmm for the transmission of the
DMX signals, as well as two lines á 2,08 sqmm for the supply voltage of the Colour Changers. The
high cross-section of the live wired lines considerably increases the maximum cable length, which you
can use within the system. In order to ensure a reliable operation, you should not use more than 300
m total cable length (theoretical figure) per output. Please note that you have to differentiate between
the theoretical cable length and the actually usable cable length.

(You have to add the total cable length between each Colour Changer and the PSU in order to
calculate the theoretical figure.)
Control-displays:
The Maxi 4 PSU has 2 control LEDs, which are situated on the same side as the sockets:
The red LED shining permanent indicates that the 24 V DC supply is OK.
When the "termination"-switch is activated, the red LED is flashing.
The green LED indicates that a DMX signal is present at the XLR5pol. input.
The Micro PSU has three LEDs:
The yellow LED indicates that the "termination"-switch is activated.
The red LED shows, if the 24 V DC supply is OK.
The green LED indicates that a DMX signal is present at the XLR5pol. input.
