I am trying to move my WMII onto a low powered 'Justo'p which runs
Windows 8.1, soon to be upgraded to Windows 10. Only just got it.

The problem I have is my Weather Station is connected via a USB to
Serial adaptor cable. This has been working on my old Windows XP PC for
some years now. I have found the old CD with the driver but it still
won't recognise any ports.

Any ideas or help would much appreciated.

I am running Windows 8 and using several usb to serial adapters. I've
just checked in Device Manager and the following drivers are loaded:

Prolific USB-to-Serial Comm Port (COM1 & COM5)
Silicon Labs CP210x USB to UART (COM3)

You can get the Silicon Labs latest driver from here (which I think you
will need for the Davis AWS to work):
http://www.silabs.com/products/mcu/P...CPDrivers.aspx

And the Prolific drivers from he
http://www.prolific.com.tw/US/ShowPr...id=225&pcid=41

Hope this helps.

===========================

The Prolific drivers will be for the old 8434 Davis serial-to-USB adapter
(or some other adapter that also uses the Prolific chipset) and, to the best
of my knowledge, aren't compatible with modern versions of Windows such as 8
and 10.

The SiLabs one will be for the Davis USB logger, which Keith will not have
for a WMII.

Only solution that I know offhand is to get a new serial to USB adapter that
does definitely have a Win10 compatible driver, preferably an FTDI chipset
one - they seem to keep their drivers more up-to-date than any other chip
designer. If you get stuck then we do sell an FTDI one - it's not the
cheapest but it does definitely seem to be compatible.

Dang 'n' darnation, for some reason I read Keith's email that he was
going to upgrade to Windows 8.1.

It's been a long week......... I need some hot sun on me old bones.

Thanks John,

I think I have tried some of the drivers mentioned above, abut will give
it another go tomorrow. do you have a link to a new serial to usb
adaptor which should be compatible with Win 10?

Much appreciated all the replies.

The old Prolific chipsets don't have drivers for Win8 either AFAIK (I think
that any driver that works under Win8 should also work under Win10 and vice
versa). The problem is that just saying Prolific doesn't really define the
chipset - I think there are at least two sets of Prolific chipsets (very
possibly 2) and while there may well be Win8/10 drivers for more recent
ones, these don't necessarily work for the older chipsets eg as were used in
the Davis 8434 adapters. That's why I prefer FTDI - they do seem to be able
to maintain both chipset and driver compatibility over time.

@Keith: Drop us an email or phone on Monday morning and we can talk further.

I have a USB to serial converter I purchased from Maplin some time ago
which I still use for downloading data from my Garmin GPS. I have just
plugged it in to the USB port on my Windows 10 desktop and it shows up as a
Prolific USb to serial COM3 port, the port number is dependant on the USB
port in use.

I am almost ceratin that I never explicityly loaded these drivers so I
think they are available from within either Windows 8 or 10; the PC came
with Windows 8 originally. In any case the Prolific drivers can be found
online. I have just checked and it is working fine.

========================================

Sure, it's always worth trying it before concluding that something new is
needed - Win8/10 etc are getting much better at finding drivers
automatically than ever used to be the case with older versions of Windows.

But Prolific in particular went through a phase where they were very slow to
write new drivers especially for their older USB chipsets. To the best of my
knowledge, some of the older ones have still never been updated for Win8/10
compatibility - maybe there's some technical issue as to why it can't be
done.

Looking at the Prolific website it does state:
NOTE:

Windows 8/8.1/10 are NOT supported in PL-2303HXA and PL-2303X EOL chip versions.
Run PL2303 CheckChipVersion tool program in Windows XP/Vista/7 to check chip version.
Windows XP, 2000, 98 and Windows ME driver technical support is discontinued.
Prolific recommends to use PL-2303HXD (HX Rev D) or PL2303TA chip.

Just tried again testing each COM Port 1 to 10 individually, no joy.

I'll be in touch John :-)
