DAVIS NOT FOUND

[meteoperugia]

Hi everybody.
My old iMac (late 2006, OSX Lion) dedicated to weather station can't start because of a videoboard problem (ATI on board). If I start iMac in secure mode (with shift) machine start and run without problem but WC can't find my Davis and in the WC panel thEre aren't USB ports available (no more silicon labs UART port). I've dowloaded and reinstalled Silicon Lab driver but without results. Maybe in secure mode OSX can't see/use 3rd part drivers....?

There is a way to run WeatherCat in Secure Mode?

Thanks in advance.....

Im not sure, but maybe the secure boot switchs off the usb ports?..

Other USB devices but Davis are running. UART USB 201x is present in system features list but not in WeatherCat port list, so I belive that the problem is 3rd party driver and not USB ports......

I don't know why system boot and run only in secure mode but I think is a logic unit problem. I'm wondering to run WC with secure boot.......

Have U tryet it in other usb port?

[meteoperugia]

..yes!

Ok. Maybe like U said, os x dont load 3d party drivers in secure boot...

Hi Federico and WeatherCat fans,

My old iMac (late 2006, OSX Lion) dedicated to weather station can't start because of a videoboard problem (ATI on board).

I don't think there is any way to connect to your weather station in safe mode.  Safe mode disables the loading of all drivers.  That's a feature not a bug since of course the drivers could be the cause of the problem you are trying solve.

So I'm afraid you are going to have to resolve that video board problem before you can get do your weather station.  If it is any comfort, you have some time to do that before your data logger will completely fill up.  Here is the information on how much time you have depending on your sample interval:

Good luck Federico!!

Thanks Edouard, that's as I supposed…..

I contacted someone who says be able to repair the logic unit and recover video board. I'm waiting for reply…….
Maybe lose a few days of weather data at this time due to the data logger but this is a minor problem.

Thanks again and cheers!

Federico, let us know how that repair turns out. Sometimes, the right guy can work magic.

Hi Federico, Blick, and WeatherCat Davis fans,

Hope that works out.  Fixing hardware is getting difficult because of the complexity.

Maybe lose a few days of weather data at this time due to the data logger but this is a minor problem.

If you have sample interval set to 5 minutes, you have a little under 9 days of storage on the Davis station itself.  Hopefully that's enough if your guy can make the repair quickly.

Good luck Federico!

Cheers, Edouard
