Power/Data cable
In order to guarantee a reliable operation, we strongly recommend the use of our Major
Power/Data cable. This XLR4 pole cable contains two lines á 0,38 mm² for the
transmission of the DMX signals, as well as two lines à 2,08 mm² 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.
Example:
1. Actually usable cable length: 145 m (see systemdrawing)
2. Theoretical cable length: 290 m (please see calculation chart below):
Colour Changer no. 1
=
50 m
=
50 m
Colour Changer no. 2
=
50 m + 45 m
=
95 m
Colour Changer no. 3
=
50 m + 45 m +50 m =
145 m
Total theoretical cable length in this drawing
=
290 m
(You have to add the total cable length between each Colour Changer and the PSU in
order to calculate the theoretical figure.)
