Hi Jean Fredrik

I'm assuming the usb cable connections are good?

Tried another usb port on the Mac Mini ?

What messages do you have if you open Console, does it list any USB problems? If so what are they ?

rebooted WeatherCat to see if it finds the usb connections again ?

Rebooted the mac mini., to see if that re-connects the USB ?

Hi Jean Fredrik

I'm assuming the usb cable connections are good?  =>yes

Tried another usb port on the Mac Mini ? => same problem

What messages do you have if you open Console, does it list any USB problems? If so what are they ? => can you tell me the command in the console for log

rebooted WeatherCat to see if it finds the usb connections again ? => yes weathercat ok after rebooted WeatherCat

Rebooted the mac mini., to see if that re-connects the USB ? =>  yes weathercat ok after rebooted mac mini

HI

i will switch to a datalogger IP , i need stability;

can you confirm me that weatherlink IP is 100% ok with weathercat ?

thanks

No data logger IP available to test here on my side, but on the other side I can confirm that my Mac-USB-data logger connection is 100% stable. Just to make sure: Do you use a Mac data logger or is it a PC data logger? If it is a PC data logger, it *may* not work correct on a Mac.

Cheers,

Hi Jean and WeatherCat fans,

Sorry, what I'm about to suggest is only in English, but there is some troubleshooting tips for Davis Weather stations on the WeatherCat Wiki:

If you can make sense of the suggestions, it might help you at least rule out common connection problems.

Cheers, Edouard

hi edouard

I will eliminate the problems one by one

-i include a Ferrite core on the console end of the adapter power cable.

-i includes a Ferrite core on the usb cable datalogger .

Hi Jean Frederic and WeatherCat fans,

It appears to me that you have already done most of the troubleshooting suggestions we have on the Wiki.

Certainly, carefully look over your entire weather station setup for anything that might be damaged or out of place.

Check the cables to make sure they aren't cut or damaged in some other way.

Also, try removing the datalogger and carefully reseating it into position.  Dataloggers have gotten loose on the Vantage Vue.  Never heard of it on the Vantage Pro-2.

If you try all these things and you still have problems, I recommend that you get in touch with Davis Instruments.  You should be able to easily get the same reliability as the rest of us.  If you are having problems, it is because of a bad component somewhere.

Best of luck getting your station to upload reliably!! 

Cheers, Edouard

hi

i think found the problem:

my AC adapter have not a Ferrite core on the console end of the adapter power cable. so i include one ferrite at the end of the adapter power cable and now no problem with the datalogger and lost usb coonection

and now i try the weatherllink-ip => 

cheers

Dear Jean and WeatherCat fans,

Glad you found plausible source of electrical interference and were able to solve the problem by putting a ferrite clamp.  For intermittent errors like this, interference is the most likely cause.

Glad you found our community and are enjoying WeatherCat!

Hi Edouard

something very important to have the firmware of the console with the correct update
I use a weather envoy and I did not understand some troubles with both the USB datalogger and the IP (errors coms)
I verified the firmware, it dates from 2008 (no comment please ) i update the firmware with the latest available and everything is impeccable 

Good data elements received from weather station:
42885
Data link timeout errors:
0
Data link invalid data errors:
0
Weather station sensor errors:
0
 

cheers
