What do I need?

[Mark Bianco]

Roger,

I control my two 6105 with my Apex I want to be able to add two more pumps, two pumps in paralle on one channel and two pumps in paralle on the other chanel. I guess what I need is two splitters.

Thanks in advance
Mark

I think what you would need would be from Apex, I think they offer such an adapter. We have our splitter 7092.340 but I am not sure if it works with the Apex.

Tunze Splitter does not work with the Apex. Each port on the Apex will control 2 Tunze pumps. Apex makes a cable for this OR you can find the pin out for the cables all over the internet and make your own cable.

When I had an Apex I made a cable that allowed each Apex port to control 4 tunze, but the Apex will see two Tunze as one so you cannot control each Tunze by itself.

Roger,

So in other words the Tunze branch adapter 7092.34 will not work for what I want to do?

Having never used an APEX, I would have to defer to Pyton, it doesn't sound like it would work.

If you are referring to the 7092.340, yes it would work. I am running one now. You would need a 2 channel Apex cable to plug into the 7092.340. This would then Y off both cables and you would use the cables supplied with the 7092.340 to plug to the pumps.

The other maybe simpler option would be just two 2 channel Apex cables and give each set of pumps the same profile and call it a day.

Neptune Systems can say it was never meant to be run that way and void your warranty, If you use the splitter. That is why I said it will not work. Research the net about this issue it is pretty well documented. I went through a a couple of them because the 1-10V port were going bad. After the second one I was told one port one cable, that is why they sell the add-on module.
