I have one question regarding the fact that I can not have the time zone

Help / FAQ OPEN CPN As a Slave or as a master with the chart plotter

It will be nice with OPENCPN to behave as a slave or as a Master in front of NMEA connected GPS;

As a Slave:
The user create a waypoint on the GPS and navigate To this wyapoint;
In that case the NMEA sentences that will be send to the GPS will be something like

$GPXTE,A,A,0.0001,L,N,A*02
$GPAPB,A,A,0.0001,L,N,V,V,291.22,T,,291.22,T,,,A*3 4
$GPRMB,A,0.000,L,,Fin,4448.5490,N,00349.8640,W,223 .632,291.2,,V,A*1A
$GPBOD,291.2,T,291.5,M,Fin,*01
$GPBWC,132441,4448.5490,N,00349.8640,W,291.2,T,291 .5,M,223.632,N,Fin,A*3F

It will be nice if OPENCPN could understand this and could activate the waypoint created on the GPS as the Opencpn navigation target.

As a Master
If the user creates a Waypoint on OpenCPN and navigate to this Waypoint, it could be nice if Opencpn could send through NMEA the following sentences
$GPXTE,A,A,0.0001,L,N,A*02
$GPAPB,A,A,0.0001,L,N,V,V,291.22,T,,291.22,T,,,A*3 4
$GPRMB,A,0.000,L,,Fin,4448.5490,N,00349.8640,W,223 .632,291.2,,V,A*1A
$GPBOD,291.2,T,291.5,M,Fin,*01
$GPBWC,132441,4448.5490,N,00349.8640,W,291.2,T,291 .5,M,223.632,N,Fin,A*3F;
or depending on configuration
$ECXTE,A,A,0.0001,L,N,A*02
$ECAPB,A,A,0.0001,L,N,V,V,291.22,T,,291.22,T,,,A*3 4
$ECRMB,A,0.000,L,,Fin,4448.5490,N,00349.8640,W,223 .632,291.2,,V,A*1A
$ECBOD,291.2,T,291.5,M,Fin,*01
$ECBWC,132441,4448.5490,N,00349.8640,W,291.2,T,291 .5,M,223.632,N,Fin,A*3F

for the navigation system to display the navigation information to reach this waypoint.

The slave or master mode could be defined by configuration.



Today it seems that the sentences
XTE,APB,RMB,BOD,BWC are not manged by opencpn

I have raised a feature request in that direction, but maybe it can work and I miss it.
Can someone ccould help?
Best regards

Opencpn errors

I am just starting a cruise from Seattle to Sitka Alaska and using OpenCPN for the first time. On my laptop, running XP, the Night Navigation turned on, without touching, it three times. What is the fix? I really like OpenCPN and I am a twenty year Nobeltec user.

You might have activated the "Inland ECDIS Version 2.3" in OpenCPN version 4.6.1. This setting is in Options > User Interface. If you have a checkmark at the "Use settings for Inland ECDIS Version 2.3" then the "Dusk" color scheme will be set each time OpenCPN is started. Remove the checkmark to turn this off.

Paul,
Thank you for the quick reply. I checked the setting you suggested and it was not turned on. But it gave me a path to try.
This was my second cruising day of a trip that is taking my new boat from Seattle to my home in Sitka Alaska. I am running OpenCPN on a laptop with XP on the Flybidge (newer electronics at that station.) At the interior station is a laptop running OpenCPN on a Windows 8 base. The same problem occurred there today.
The program kind of locks up. I can use the F5 and F6 and Shift F6 and it seems to have little effect. Sometimes it comes back, some times it crashes and sometimes I have to shutdown the program.
This 1100 mile trip has some tricky and dangerous navigation. There are many narrows that must be passed through. Today the black screen appeared just as I wad entering Dodd Narrows in British Columbia. It is a short narrows and I hit at slack with good visibility.
What I noticed today was that the program blacks out when I have more than one function running. I had, Course Up, Follow Boat, Tracking, Currents and Tides running. If I dropped Currents and Tides it seemed to behave. But I need to have C&T up so I can decide on which side of an Island to run.
So your suggestion and the seemingly problem of having OpenCPN do to much has lead me to try turning off all Items I don't need. I still have a long way to go and my version of Nobeltec can't read Canadian charts. So any input or suggestions would be great.

Re: Help / FAQ

Today I hooked my new Standard Horizon GX2200 radio which has AIS and GPS. I hooked it up to a Brookhouse iMux. I made a connection to my in OpenCPN 4.4 (Win10) to the TCP output of the iMux. I was able to receive AIS signals and see AIS targets on the screen. I have the boat's GPS also connected to the iMux and am getting GPS in OpenCPN. So far so good. Everything is working fine. Then I sent my buddy a DSC position request and this crashed OpenCPN. I tried it a couple more times and each time the request was sent, OpenCPN crashed. So, I upgraded to 4.6 and everything was working. I could see AIS targets and the GPS was working. I sent a position request to my buddy and OpenCPN crashed. It is crashing when I send the request on the radio even if before I get a response. What else would be needed to debug this?

Unhandled exception at 0x017B9479 in opencpn.exe: RangeChecks instrumentation code detected an out of range array access. occurred
