Hello,

I've read the manual and searched the net. I've tried what troubleshooting steps I found. I still can not get my MPS devices to be recognized by the aquabus. I have 2 a MPS 400 flow meter and a MPS 40 level indicator. The 2 work perfect by usb but never appear in aquasuite under connected aquabus devices or anywhere else. I feel the only thing left is hard reset. I took these steps out of the manual and just want to verify I have it correct.

1. Shut down the PC and disconnect all cables from the aquaero except
the power supply.
2. Place jumpers on temperature sensor input 5, 6, 7 and 8.
3. Supply power to the aquaero and wait for approximately 60 seconds.
The device display will show information on the deletion process.
4. Shut down the power supply and remove the jumpers from the tempera-
ture sensor inputs.
5. Connect the USB port of the aquaero to the PC's motherboard and turn
the power supply on.
6. Start the aquasuite software and perform a firmware update.
7. Shut down the PC, reconnect all cables, then reboot the PC.

Thanks for any help.

Hi apw63,

Did you set a different aquabus address for all the MPS devices using aquasuite? And then set the communication priority to aquabus?

Hard reset procedure you outlined looks correct, but that is usually only used when something goes wrong during a firmware update. Did you reseting the aquaero to factory defaults from aquasuite?

Kind regards,
Boris.

Yes I did set different address for the 2 MPS units (12 & 13) and set the priority to aquabus. I have also multiable times reset the MPS and aquaero to factory defaults.

You did not mention, but are you using a 4 pin cable between the MPS and the Aquaero.

The 4 pin cable is required to supply power to the MPS when the USB is not connected.

Yes using a 4 pin cable and a y splitter connected to the high side.

Thanks for the reply guys looking for any and all help with this.

Thank you all for the troubleshooting help and ideas. I'll be troubleshooting these this weekend and I'll keep you all updated,

Ok I was able to do some troubleshooting. Here is what I have found out. First I had the aquabus y cable one pin off on the high port., it is now attached correctly to all 4 pins. Now that would explane why I could not get any communication between MPS devices and the Aquaero. But this correction has not fixed my issues. I do get communication from the flow sensor. The flow sensor reports as a realtime clock under attached aquabus devices. I can not get the level sensor to report at all. So way is the flow sensor report as realtime clock? It only report when only attacted to the aquabus. If attached to both USB and bus nothing reports under attached devices. I tried switching the address and it still reports as realtime clock.

The y and cable length to each device is appropriately 12 inches total.

Any ideas or path forward before I ask for replacements?

What happens if you connect only one of them to the aquabus?

If I only connect the flow sensor it reports as a realtime clock. If I only connect the level indicator I get no communication.
