That's standard behaviour IIRC. If you're not downloading archive data
correctly (which you're clearly not, as per your previous post) then
the barograph has got no permanent store of pressure data on which to
call to recreate the trace whenever it reopens the program. It does
separately maintain a temporary store of recent pressure data for as
long as the program is open, but that's lost when the program is
closed. Normal barograph service should be resumed if you can get the
archive downloads working and configure automatic archive downloads
appropriately.

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.

John Dannwww.weatherstations.co.uk

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

I think we crossed there. The Weather Envoy has always run on
batteries since I've had it, and the batteries have been changed a
couple of times without incident. The date/time appears to be in
synch, too. At the moment I'm still running the console with the data
logo plugged in directly. I will try clearing everything and starting
again.
Apologies to all on the newsgroup for taking up time and space with
this, and thanks to you for your continued help, John...
I've got Interenet problems, too at the moment which doesn't help - I
rely on Wimax here in the wilds of France, and it's been a bit hit and
miss for the last few days!

Right, I've cleared all the logs and set up a new station, and this
has been running for about an hour and a half, but no data is being
recorded at all. I don't know if this narrows down the problem or
not.

This is definitely an odd one!

So to recap:

Bulletin mode is definitely running perfectly well (other than the
detail of the barograph not being able to see a store of recent
pressure data), but when you go to download archive data, well,
nothing happens?

If you look at the archive interval, what's it currently set to?
Purely for test purposes, it's often useful to set a 1-minute interval
(just so that a significant amount of archive data accumulates
quickly.)

And when you try to do an archive download, what error message do you
see - 'No new data to download'? Or something else?

Presumably the Baud rate is definitely set to 19200 on _both_ console
and WL set-up?

And even though the time is roughly synchronised between console and
PC, did you definitely check that the year is the same too?

Year, date and time checked and the same on both.
"No new data to download" message on archive download.
I've set the archive to one minute intervals, so we'll see what (if
anything) happens.
Baud rate 19200 on both.
It gives the standard message that it's about to download the next
data record in 10 seconds, unless cancelled, but downloads nothing.

I lost my internet connection yesterday, again!
Anyway, the data logger has been running overnight attached to the
console and recorded nothing. I can only assume that it is faulty,
and I guess I'll have to get on to Davis. Thanks for your help, John.

I do wonder whether your Envoy unit got hit by a mains surge?
(Assuming that it was connected to the mains?)

But it is odd that Bulletin mode is apparently working OK on your main
console, while Archive mode isn't. Generally, if the logger is faulty
then neither work.

One last thing I'd be tempted to try: Fully power down the mains
console (ie remove both mains and battery power) and leave powered off
for at least 5-10 minutes - ideally longer. Then repower, check that
you hear 3 beeps etc.

There's on other oddity in your description: You've been writing that
the VCP driver is called CP2102... (ie in the Ports area of Device
Manager) whereas it normally appears as CP210x... Maybe this was just
a typo but it does make me wonder whether somehow there's still a
problem with the VCP driver.

There is of course nowadays a different mode that you can try for
connecting PC to USB logger, which is called USBXpress. I hesitate to
describe this because it can cause a lot of confusion and I wouldn't
recommend anyone else who might be reading this (is there anyone else
out there?) to try it. But since all else has failed it might be worth
a shot in this instance.

If you start the WL program and go to the Communications Port dialogue
under Setup and choose 'USB' and not Serial, as you will previously
have done, then you will initiate a process that will try to switch
the logger into USBX mode. A couple of warning messages may appear and
you may need to repeat the process until it's successful. And you may
also need to reboot your PC before the link works again. But it's just
conceivable that the logger will work in USBX mode while it wouldn't
in VCP mode. (NB You will no longer see a VCP entry under Ports in
Device Manager. Instead there will be a USBXpress entry under the USB
Controllers section.)

If you do need to go back to Davis then I'd be interested to hear the
outcome.

The Weather Envoy has always been battery powered...

I tried what you suggested, and although it said it had successfully
converted to a USB port, it makes no difference.

Now I have the data logger back in the Weather Envoy, the graphics on
the Bulletin window have gone up the shute again - nonsense barometer
reading, etc, and everything else blank.

I'll try and power everything down, but I have a feeling of doom about
all this.
