Imagine what it would to to the prices of all fairly cheap instruments
the moment they need a more powerfull processor and more memory to run
a TCP/IP stack......

What processor? Off-the-shelf components used to interface cheap
computers to TCP/IP?

Here's a whole Ethernet IP communications device on one IC...

IC

Oh, oh....I forgot.....these are STANDARIZED parts, not NMEA
manufacturer proprietaries.....(c;

Yeah, they'd raise the price $10/unit, I suppose.

Think the market would bear it if everything could talk to everything else?

Well I can't resist! The use of the TCP/IP stack for this application
is just plain stupid! Every recently manufactured car and there are a
hell of a lot of them has the Bosch 2 wire Controller Area Network
(CAN) communications bus connecting all the various elctronic
controllers. This bus is also the basis of NMEA 2000 spec. This
technology was designed for noisey environments, is robust and has very
high levels of silicon integration to get data on and off the bus.

BTW don't trash the technology just because the NMEA marketing arm has
it's 'head stuffed where the sun don't shine' It works very well in the
auto industry worldwide and should work as well in the marine industry
if the NMEA can get over their big boys club attitude to licensing IP!

Meindert is right TCP/IP is just plain stupid overkill!

Hear hear!

And indeed, NMEA should drop the prices. It's just too expensive for small
companies to pay $10,500 to get on the NMEA2000 train....

B.t.w.: it is not that hard to come up with a protocol/interface that
combines the simplicity of NMEA, the multi-talker features of SeaTalk and
the robustness of CAN for just a $1-2 per unit.

Same game they're playing with the yachtsmen. Planned obsolescence. Look
around any marina at the dead carcasses of NMEA's past renditions.....

How many NMEA serial port versions have there been? First we played the
data speed game. Then we "expanded" the protocol instructions.

Of course noone was to blame.....everyone was to blame.

What's your point? This has happened with ethernet as well (coax, twisted
pair, 10,100 and 1000Mbit...)

Don't forget industry consolidation too! Simrad bought out Navico,
support for Navico POOF. Try to get support for that brand now! B&G
users please take note.

That's why when I chucked out my Navico GPS and autopilot I went with
Raymarine!

It is a fact that technology is accellerating and if you need to stay
at the bleeding edge you pay a price. Sometimes it is worth it but I
fear most times it is not. Marketing departments are there to create a
need, often when none exists ;-) I know as I spent 25 years in sales
and marketing in the IT & T sector. Now talk about bleeding bloody edge
