For anyone that might be interested: We're currently trialling a Davis
6555 WeatherlinkIP logger. (If you've missed previous posts, this is a
new Weatherlink logger with an IP interface, meaning that it can be
plugged in directly to an Intenret connection.) I'll post some more
details once we've accumulated a bit of experience,

Davis seem to have decided to release this part more quickly than I
anticipated just a couple of weeks ago and it should be available here
hopefully within the next 2-3 weeks. Haven't got an official price yet
but apparently it will be the same as the other specialist loggers eg
6550.

You can see our data on the central Weatherlink website from this test
installation at:

http://www.weatherlink.com/user/prodata/

(NB This is only a test at our end at this stage and so the live data
may be limited and intermittent.)

That sounds very interesting. Let me know when you have more information
on this.

I'd be particularly interested if the IP logger can be used without the
weatherlink software. This would save me having to keep more than one
computer on all the time - especially if I can retrieve the data
remotely (my VP is still in Canterbury as a friend lives at my old house
but I have to keep a computer on there to retrieve the data over the
serial port and upload it to my own database).

The answer is yes to that, though with caveats.AFAICS the 6555 logger
will (initially at least) have two modes of operation.

One will be passing data locally to the Weatherlink software (v5.8 -
not yet formally available) in the familiar way.

The other will be uploading data directly - ie with no need at all for
a local PC, just an Ethernet connection to eg an ADSL/cable router -
to a server at Davis, which is what our test is currently doing. As
well as being able to view your data online in the standard Davis
format, it will then also be possible for you to download archive data
records (but not loop data, which won't AIUI be stored centrally) from
the Davis server. So the Davis server can in a sense be used as a
proxy source of the archive data.

In time there might be other modes of operation possible but it's
premature to speculate about that at present.

John,

Out of interest, is this a wired conection to the internet, or wireless ?

It's a generic TCP/IP connection. Typically it would be behind a
router of some sort but that router can be any flavour that can
establish a route to the target server for the data (ie currently the
Davis data server). So it can be cabled or wireless.

The demo that we have running currently is just behind a standard
office Draytek ADSL router but in principle anything appropriate
should be able to do the job, though obviously there might be some
practical details to sort out for more exotic hardware. To be clear,
you can't attach it directly to an ADSL-enabled phone line - there has
to be some sort of routing box that it plugs into, but any common and
inexpensive sort of modem/router providing an Internet connection
should suffice. If you're interested in any of the more technical
details then maybe contact me offline. Email address is valid.

I think Phil was asking what the logger uses to talk TCP/IP over. ie is it
a wireless device requiring a wireless network or does it just have a bog
standard ethernet port. I get the feeling it's the latter.

OK, to be 100% clear: The connection on the 6555 logger is a standard
cabled RJ45 Ethernet socket, ie requiring a cable to connect to some
other network access device like a hub/switch or directly to the
modem/router that provides Internet access for the local network.

The simplest configuration would be for the 6555 to be connected
directly to an Internet modem/router (indeed the simplest
configuration would be just the 6555 and a basic modem/router -
provided it can provide a DHCP service).

But the 6555 can optionally be connected to a hub/switch on a larger
LAN (which is actually the test configuration I currently have
running). And I can't see any reason - though haven't actually tested
this yet - why the 6555 can't be connected to the WiFi equivalent of a
hub/switch (is that a wireless access point - I get a bit confused
with the terminology of WiFi LANs, they seem perversely different from
cabled LANs to no great advantage though I dare say there are
technical niceties as to why something doing an apparently similar job
should be called something different) and thence have the weather data
relayed over a WiFi leg of a local LAN to the LAN's Internet access
point.

I can add a bit more to yesterday's report. I now have the 6555 logger
streaming data to a local copy of Weatherlink v5.8 (don't look for it
just yet, v5.8 is not quite available for public download right now,
v5.7.1 is the latest downloadable version) in Bulletin mode, at the
same time as streaming data up to the Davis website. So the capability
is there - should a user wish to do so - to use Weatherlink locally in
the time-honoured fashion at the same time as streaming data up to the
Davis website. This might typically be useful for someone to make
their weather data publicly available 24/7 via the Davis website
without needing to run their own PC continuously tp provide uploads to
their own website. The only device other than the VP/VP2 station and
6555 logger running continuously would need to be the Internet
modem/router, which is usually the case anyway. But as and when you
were ready to switch on your local PC you could still access all the
logger data (either directly ie straight from the logger itself or as
a download from the Davis website).

As i thought. B-) KISS applies, cabled LAN connections "just work" and
are more flexable, three options spring immediatly to mind, straight cable
to tyour LANS switch, wireless via a wireless bridge or powerline ethernet
(uses the mains power wiring to link ethernet devices).

And I can't see any reason - though haven't actually tested this yet -

Not helped by the rather generic marketing terms used for devices that
include, ADSL modem, firewall, router, ethernet switch and wireless access
point all in one box.

The only advantage is that you don't need a cable for your laptop or PDA
you can just "use it" anywhere within a few tens of metres of the Access
Point. The payment for this is lack of security of your network unless you
take action (change default users/passwords, enable or strengthen
encryption etc) and reliability/speed.

though I dare say there are technical niceties as to why something doing
an apparently similar job should be called something different)

A wireless Access Point provides access to a LAN via a wireless interface,
more than one remote device can access the LAN via a single Access Point.
To connect this new VP logging device wirelessly you'd need a wireless
bridge to plug the ethernet port of the logger into.

John,

I looked at the faq but didn't see an answer to my question, namely how
much data is transfered each minute? I would like to know the ball park on
this to see any possible impact on my data limits with my isp. Do you know
the value?

Cheers

Sky.
