Mitras Light Bar 2 Cable Length and Setup Questions

I require 4x 140cm lights, totalling approx 400w power. The max power unit available is 320w so i will require 2x 200w units. Is the below setup correct for my Profilux 3 with 4 Mitras Lightbar 2 units?


Profilux 3 > RS232 Active Splitter > (1x 200w power to 1x Lightbar Splitter > 2x Mitras Lightbar 2 fixtures) > (1x 200w power to 1x Lightbar Splitter > 2x Mitras Lightbar 2 fixtures).


Does this lightbar come with a cable already connected to the lightbar or must I purchase a cable? If connected, how long is it and can it be extended using the Mitras Extension cord?

I see the Active splitter includes 3 cables, a RS232 and 2x RJ45. Do I require any other cables?

Thank you.
