I'll try that, John. I uninstalled the CP2102 USB to UART Bridge
Controller from Device Manager , then disconnected the data logger.
When I reconnected the dater logger it was recognised as a USB device
(CP2102 USB to UART Bridge Controller) and installed itself, but could
find no drivers, even on the Weatherlink CD. so I'll download the
latest version from Davis. And I've not installed any other drivers
recently, and yes it did just stop working. I did expect the CP2102
to also be present in the Universal "Serial Bus Controllers" drop down
in Device Manager, but it is only in "Other Devices"

Thanks, CK

Updated to v5.8.3 - still the same, plug in the Weather Envoy, the
CP2102 device is recognised and asks for the drivers. I point it to
the folders where the drivers are, but still won't install. What a
pain. I give in !!

OK, it does rather look as if this is an awkward problem.

A couple of observations:

You shouldn't need to point to any driver location when you connect up
the the USB logger - it should self-install. If it doesn't then it's
an indication of something more basic wrong, perhaps with Windows.

Have you installed Weatherlink under an admin login? (If not then
there could be some obscure permissions problem).

If you run the 'CP210x USB USB to Serial Converter' which is a simple
utility found on the Windows Start menu in the Weatherlink group (and
'press any key to continue') then does it say anything other than that
the logger is already in serial mode?

If none of these give a clue then there are a couple of other options,
but I don't want to suggest those until you're tried the above.

A little progress, but not much. Ran the USB to Serial converter
utility, which told me that it was now operating correctly.
Auto Detect now informs me that a Vantage Pro Station has been found
on COM4 (which is a step in the right direction).
Attempts to download data result in "No new data to download" (The
last record was at 22:00 on 7th June).
Opening the Vantage Bulletin window results in gibberish - the
graphics are there, but not filled with data apart from the total rain
for the month and year, and the barometer reads: -1109655.5 mb!. No
temperature, humidty, wind data, etc., etc.

On going through the setup walkthrough, when it came to "Set
barometer", the console reading is ".. mb", and pressing OK eventually
resulted in a message that "Computer gave up waiting for response from
station. Check port setting and connections. This is becoming like a
merry-go-round!

Brief comment till the morning: I would

1. Completely power down the Envoy - both mains and battery. Give it a
good rest overnight;

2. Power up again in the morning. If you can re-establish contact with
the Envoy then that check date and time, not forgetting year, are all
synchronised with PC!

3. If still no joy then move the logger to your main console, if
feasible, and see how that goes. At least that might tell you whether
it's the logger or console that has a problem.

Didn't see your last until this morning - I've now connected the data
logger module direct to the console, and that seems to work OK.

Having said that, although the graphics appear to display correctly,
nothing appears to be being downloaded or saved since 22:00 7/6/09

This is usually a date/time issue, either on the console or on the PC
- they need to be approximately synchronised, preferably with the
current date/time! (Presumably the logger did give 3 beeps when you
powered up the console again after installing the logger?)

It could be that if your Envoy console has developed a hardware fault
(which would be quite a rare occurrence - unless caused by a mains
surge) then it may have corrupted some of the data in the logger and
this is preventing proper logging/downloading of new data. I would
try:

1. As a test, try creating a new station in Weatherlink and
downloading into that. Sometimes, if there is a data corruption issue,
it may have also corrupted the main monthly data file on the PC and
this is preventing correct data downloads. It's worth trying to do
this first before...

2. Clear the logger to see if this will also clear any corrupted data,
leave the logger for a while to accumulate new data and try again. To
state the obvious, the step will delete any (valid and invalid) data
in the logger that hasn't previously been downloaded. Of course if
your Envoy may have been faulty for a while then there may not be much
valid data to lose.

.... and when I open the programme, the barograph trace starts from
that moment. If I leave the programme running, the trace increases
with time. If I close the programme and re-open it, the barograph

expect it all to go *its up so soon, it's less than 2 years old!
