Octo (Reef Octopus) wave and return pumps control

Purchased Octo Pulse 4 wave pumps which are Apex Ready with 0-10V port, is it possible to control them using Profilux 4?

The standalone controller only allows 30% to 100% power.

Any Reef Octopus users?

Thanks for the quick reply. So this 0-10V cable can be purchased through GHL and it plugs straight into the back of the Profilux 4 or do I need a module similar to the GHL Vortech module?

A suitable cable is not available directly from GHL
There are several ways to connect the pump to the Profilux
1:
You buy a cable with RJ12 plug 6p6c and install the audio plug on one side.
2:
you buy a cable with the audio plug, and connect it with a 6p6c RJ12 plug.
3:
You buy a cable with the audio plug and connect it to a (LBF-AP) (PL-0067) if you can buy another one

Thank you.
So with both pumps connected to the Profilux, I can program them at any % power and to operate in sync or anti-sync (mirror) ?

Yes, with all the features the Profilux offers. You may have to increase Umin at the 1-10V settings. You have to try ~2.4V.

I have an audio splitter cable - 3.5mm that goes from a female connection into two audio plugs.

Inside there are four cables and they are very thin and appear to be red, blue, sort of yellow and green.

Does anyone have any idea about how those would fit into a RJ12 to provide control over two Reef Octopus pumps?

You can use the new S-Port & L-Port Breakout Box (S-L-Port-BoB)

Thanks Pit, I am aware of that. I still wouldn't know what wire goes where so what's the difference between attaching an RJ12 or using that box?

If you or someone else could help me with the question then that would be great.

The breakout box basically fills the incompatibility gap between the communication cable and the ProfiLux. If there is no dedicated GHL communication cable, users will still be able to control their 1-10V devices by connecting which ever communication cable to this breakout box. The other-end of this com cable is then connected to the port on the 1-10V device itself.

Thanks Vinny, I understand how the breakout box works. I still wouldn't know how to use this cable whether connecting it to the breakout box or an RJ12 as I have no idea which wires are which. If I knew that then I could use a breakout box or an RJ12.

The cable colors are not standardized, so we can't know which cable fits which pin.

I had a feeling that would be the case. So the only way is by seeing how the wire is connected to the aux pin and hoping it's the same at the other end...

All you have to do is measure the cable.

So probably easier to get a simple single cable and just connect the wire connected to the wide part of the connector to pin 3 and the other cable to pin 2 or 5, based on a diagram in another thread on here.

It looks like there should just be a negative and positive. Would there be any harm caused in getting them the wrong way around in a 2-wire cable that's just controlling a return pump?

Ok, I bought a Breakout Box.

The aux cable has three wires - bare (assuming it's the ground), white and red.

I bought a multimeter. No idea what I'm doing but connected the assumed ground and then found no variation on the reading with the red wire and various readings and varying pump speed with the white wire.

What wires should I connect to which terminals? I assume the bare wire to terminal 3. White to 2? Red to anything?

I think this is all you need:

Now you need to find out, which of the 2 rings resp. the tip of the jack belongs to which cable.
Usually the yellow ring is GND and goes to the shield (bare).
Not sure about the other 2, but a DMM will show you if they belong to red or white.

What's a DMM?

When testing the wires with a multimeter I get nothing from the red wire and fluctuating readings from the white wire, so I'm guessing that I just connect the bare ground wire to terminal 3 and the white wire to terminal 2, but I've not done this before or actually used a multimeter before so I'm hoping to get some confirmation?

I guess DMM = Digital MultiMeter...

So the wire that provides a reading would be the wire that I connect to terminal 2.

I'll give it a go and see what happens.

That worked fine. I assumed the bare wire was the ground and then found the wire that gave a reading with the multimeter. That wire was put in terminal 2 and it works fine. Using a multimeter was the key to this and once I got hold of one it was easy to get this working.

Far simpler than I was thinking and the breakout box does make it far easier than fiddling around trying to get two wires into the slots on an RJ12.

For all who are also looking for a well documented solution. After some trails and errors finaly this works for me to connect my octo pulse to the profilux.

Für alle die noch nach der Lösung suchen, wie die Steckerbelegung für die Octo Pulse Strömungspumpen auf der Break Out Box funktioniert (für mich war die Doku hier sowie die bei der Box beigelegte nicht ausreichend) anbei das Bild.

Excellent!
