Hi guy's

Each time it too bad weather to sail I tried to finalize te setup of navigatrix.
The last thing is to succeed to get NMEA stream from my multiplexer.
The following configuration was used to work under windows ...

EM-Track connected through serial for GPS position and AIS. This one is working fine
Multiplexer (http://www.gadgetpool.de/nuke/downloads ... rEn1_8.pdf) is connected through USB. That's where my problem begins ... Up to now I didn't succeed to receive stream in openCPN. With Terminal, I didn't succeed to check if there is stream.

pegase@pegase-desktop:~$ dmesg | grep tty
[ 0.000000] console [tty0] enabled

pegase@pegase-desktop:~$

ttyUSB0 is member of dialout. I checked this with this command

ls -l /dev/ttyUSB0, that returns crw-rw---T 1 root dialout 188

Then I try to display the stream in Terminal with

cat /dev/ttyUSB0

But I get the message : device or drive busy.

For Opencpn config I attached printscreen.

And now
What can I do to go further ? What can be done ?

Many thanks in advance.

Hi Guy's

Just let you know that I found the solution.
In fact under Ubuntu GPSD is automatically activated and therefore ttyUSB is not available.

This function is described in OpenCPN user's manual... http://opencpn.org/ocpn/options_connections

Unlike Ubuntu, Navigatrix uses gpsd to:

• keep the system clock accurate,
• provide locations so the screen dims at night,
• inputs location into Airmail,
• the planetarium (Stellarium),
• as well as the obvious geolocation functions in other applications

...transparently.
