Matt,

If the C80 can get waypoints and routes from the NMEA messages
GPWPL/GPRTE, than if I connect directly my Garmin in the serial port
sending these messages to the C80 it could read these messages and
them, I would not need the CF card reader/writer, yes or no?

Thanks

Pascal

Addendum, I would not need the CF card nor the Raymarine expensiv
software ....

Probably not. The serial port is RS-232C. Ones and zeros are +12V and -
12V levels. NMEA's bus, in their infinite stupidity, used RS-422 standard
because it's cheaper to build a data system that uses 0V and +5V for zeros
and ones. Your serial port "may" respond correctly, but again it may not
because the voltage levels on the bus are all wrong.....sorry.

They didn't want you to hook it to a computer....They don't MAKE and SELL
computers....

That is nonsense. A line driver chip for RS-232 or RS-422 are about equally
cheap in quantities. RS-422 is much more robust in a noisiy environment
because of it's balanced nature.

That is indeed the case. It may or may not work. See
http://www.shipmodul.com/en/connections.html for instructions how to connect
a single ended interface (RS-232) to a differential one (RS-422) if you want
to try it, Pascal.

That is indeed correct. Although Raymarine makes Raytech Navigator, they are
reluctant to get into the computer business. We tried to hook them onto our
USB multiplexers, but they wouldn't. They just went for the serial one, with
the RS-232 interface stripped....... It had "NO PC connection" written all
over it....

Thanks Meindert,

My friends boat is being delivery from Rio Grande do Sul to Bahia next
month, and we definitively will try this, making a interface cable
based on your instructions.

BTW, the Raymarine site has the folowing information about the C80
Interface using a new free utility program to do this, using the Cf
card and Excel:

=== Transfer waypoint data between a Microsoft Excel file and
Raymarine C-Series displays.

Requirements:

Raymarine C70, C80 or C120 display

A Windows PC with a Compact Flash reader/writer

A Compact Flash Card. To ensure the integrity of your map data,
Raymarine does not recommend using the Navionics Gold map card for this
procedure.

Microsoft Excel



====To upload the wpts and routes from the CF card, the procedure
would be as folow:

Restoring Waypoints, Routes, and Tracks
If you had backed up data before the upgrade, you can now restore it
using this procedu

Insert a card into the card slot.
Press the DATA button.
Press the ARCHIVE & TRANSFER.
Press the RETRIEVE FROM CARD.
From SELECT LIST, choose WPT (Waypoint), RTE (Route), or TRK (Track).
The card contents for your selection appear on the screen.
Use the track pad (up/down) to select what you want to retrieve.
Press RETRIEVE ALL or RETRIEVE GROUP/ROUTE/TRACK as appropriate. A
message box appears to show that the information is being written to
the display.
When the transfer is complete a message will appear on the screen.
Note: Pressing the RETRIEVE ALL soft key, will retrieve all of a
Database list to the display.

Raymarine posts firmware updates for their C and E series equipment which
can be downloaded to CF and read into the equipment. The same CF can be used
to save waypoints prior to doing the update, provided you save them before
downloading onto the CF the new update.
Their is enough room on a Navionics chart to add the updates, but menus must
be set up correctly or the display will update every time it is powered up.
Raymarine tech support should be able to explain to you how to add an update
to a Navionics card so it updates only once.
