anyone tried to using Jebo WP40?

Thanks. I am just wondering what would be required for interfacing with the Apex module. The board that elFloyd referenced earlier is said to be working, but that is a 0-10V interface.

As long as it's analog (not familiar with Apex) it should work. You would need to limit it to 0-5v in your code. Either that or use the RA adapter if you can. I think Roboerto put some extra gizmuchies (non-technical term for electronic parts/pieces) in the harness to cut the feed in half. I believe the harness will work for either PWM or analog feed too. Best to check the thread over on the RA forums to be sure though.

See post #841 just above. Apparently that will not work for the Apex.

Thanks bhazard for the info. So the harness will eliminate the pump controller and interface directly with the pumps?

I was wanting to interface directly to the Apex and program it to control the waves. That way I have access to feed modes, sync, etc. If I have to use the controller that came with the pumps, it would not be the end of the world.

There are multiple ways to go about control. With the 0-10v module, technically you could just set it on the high power mode, and still control the pump however you'd like with the Apex. If you wanted the randomness of the ELSE mode, you would still be able to use it, and have the Apex control its intensity.

Interfacing directly to the pump with the Apex will lose the ability to access the other modes. Since the Apex doesn't have a random mode for the pumps, it would be beneficial to keep the controller in the chain.
 
This is a repeat, but no one answered.

Any thoughts as to whether or not you could SPLICE two pumps to one controller???

I would like the pumps to work in sync. Pretty hard to do manually.

Oh, so these can't be interfaced like the Tunze pumps. I was assuming they would.

I just didn't want my 2 pumps running at full blast at the same time. I wanted one to run at a max power, while the other was running at a low speed, then reverse after a time.

With two 0-10v PWM modules, you can do that. You can either have the pumps share one ethernet cord to the apex, or use two ethernet cords if the two VDM ports arent being used. You can then synch the pumps via the apex, or program them however you want.
 
Just ordered 3 WP-40's, now comes the waiting... Anyone else go thru the pre-order process? If so, any remembrance of time frame until shipped?

BTW, connecting the VA wire to an Apex cord directly on the positive side and providing less than 5v doesn't spin the pump either. Tried that too.

Did you connect the ground wire on the 0-10V port to the ground of the pump? Otherwise they are operating with potentially isolated grounds. I would suggest putting a meter on the +0-10V output after you connect the ground and before you hook it to the VA line just to make sure that the reading is in range.

Also you are disconnecting the VA line from the Chinese controller or running without it entirely? If you are simply trying to connect to the VA line with it still hooked to the Chinese controller, you will not be successful.

The Apex 0-10V *should* work as the RA is already able to control it with its 0-10V output.

So is this pump going to get quieter over time or what? Pretty noisy brand new....

Just thinking aloud here but I have a few observations.

1. The controller in the pump already has the ability to limit the pump speed (as evidenced by the H/L setting.

2. There is likely a microcontroller which has been programmed at the factory to perform these settings - I haven't seen anyone ID it yet - but I'm assuming that it is a standard chip.

3. My assumption is that with a standard chip it may be able to be reprogrammed or replaced allowing us to customize the modes that are available with the existing buttons and/or interface with some other signal (from a separate controller).

Out to lunch here?

I keep forgetting about the grounds. Makes sense. VA is removed during the attempt.

I have each pin connected to wire nuts for easy swapping, since I've done it so many times already. If I was going this route, I'd rather wait for the RA harness, since it would be nice and clean.

Can't wait to see these things being controlled and synced. We should all share programs too.
 
I've noticed one of my pumps is a little more audible than the other at the same setting. Could be the same way for each of our pumps, with a slight variation in noise between them all.

My overflow and return pump drown both out anyway, but I could clearly hear my MP40's over them when they were up.
