I'll try anyways

Will this cable work with a Reefkeeper's 0-10v pump controller? RKL/RKE or otherwise?

This cable will not connect to RKL/RKE as is.

The connection on these are ethernet and RKL/RKE has a special connector. If you had the RKL/RFE connector, then the end of this cable could be cut off and modified with the correct connection, then it would work. I do not have a RKL/RKE, so I am not 100% on the connection type, I just know it is not ethernet. If there was a place to get these connections, I could build one that would work for RKL/RKE.

ReefKeeper Switch Adapter Kit Digital Aquatics would work if you have one and the wires can be spliced into this harness. I will do some reading today to see a little more, so far I haven't even had a morning coffee.

k...first coffee in the system.

Pretty sure the ALC module uses these, they look like 2 pin molex, but I do not know anyone who has a RKL/RKE to confirm.

No.

The relevant Reefkeeper module is the APC controller (Automatic Pump Controller, not the ALC = Automatic Light Controller)



Secondly, the control cable connector is based, I think, (NOT sure) upon a RJ45 jack ending (it could well be RJ11 though). The APC module is intended to control the Tunze line of powerheads.

Reefkeeper bus cables are based upon a RJ11 jack, though the pin out is different from a std phone cable, on that I am 100% certain.

IGNORE THE ABOVE

Yes and No.

there IS a two pin 0-10v connector on the ALC and MLC controllers based upon a small 2 pin molex.



The relevant Reefkeeper module for pump control, for what it is worth is the APC controller (Automatic Pump Controller, not the ALC = Automatic Light Controller). Though yes, the ALC does have a two pin style connector that can 0-10v and is a FAR more common module among RK owners.



The APC module has 4 connectors to control the Tunze line of pupmp based upon a RJ11 connector. The APC module is intended to control the Tunze line of powerheads. I know that people have used Cat5 as an underlying cable without problem though if modified properly to terminate in RJ11.

Reefkeeper bus cables are also based upon a RJ11 jack, though the pin out is different from a std phone cable, on that I am 100% certain.

I would predict that if you can modify your cable for use with a Reefkeeper APC? Or the 0-10v connector on an ALC, you could sell a LOT of these cables!

Thank you Steel_Wind.

You basically posted everything I have just read and I agree with all of it. I am just looking for the pin out on them, but my morning is being broken up with tank maintenance and other pets plus kids, so I keep getting interrupted LoL. The pinout is all that matters, which pin is + and which is -?

Cable shot.

Here is the original post which talk about how to create a 0-10v control cable for use with a Kessil A360 and the ALC 2 pin 0-10v controller. This probably tells you which is + and - to those who understand such basic things better than I.

"Then the right and white has the hots for the reds on the ALC..." So it would appear on that above picture of the ALC on top of the yellow felt, it is the one with the red wires that is +, i.e., the one on the left.

See here:

So red is + and black is - on the ALC. Pretty typical, but you never know if a company switches up the wire colors. I can easily make one of these for someone if the demand is there.

What about the APC? The APC probably would be the better unit to use.
