Reef Octopus VarioS pump control (0-10V)

I did ask Reef Octopus do they provide 0-10V cable to control their varioS-pumps and they told me to get this. Is there any way to connect it directly to Profilux 4, as the Icecap cable uses a standard ethernet jack to connect, and there for doesn´t fit to P4s 0-10V ports? Or should I connect the pumps through LBF-AP?

With their control cable you will be able to cut the Ethernet end of the cable and connect it directly to our LBF-AP box.
