Hi,

I am using two PV780 on the same network with four Engines. PV780 is suppose to displaying two Engines each. PV780 software is the same and in setup I choose what NMEA2000 instance to display. Everything fine so far!

When the second display has booted up the first display freezes. I can see that the display is active on the bus but the buttons and display freezes. Can anyone Point me in the right directon on what to look at?

Address claim seems ok.
First display booting:

6 0EA00 FE->FF 3 00 EE 00 186534.237690 R
6 0EE00 F3->FF 8 88 97 F3 54 00 A0 A0 C0 186534.349310 R

Second display booting:

6 0EA00 FE->FF 3 00 EE 00 186581.837050 R
6 0EE00 F3->FF 8 88 97 F3 54 00 A0 A0 C0 186581.847720 R
6 0EE00 F2->FF 8 90 11 F3 54 00 A0 A0 C0 186581.893110 R

Now the first display has freezed.

J1939 name fields are the same so it seems that the serial number will decide who has the highest prio.
Don´t think this is the problem tough.

What can be the problem?

Thanks, Joakim

Hello Joakim,

Did you look to see what the screens are dependent on? What conditions cause a particular screen to display?

Is the second one transmitting something that the first one sees (a broadcast) that causes the first to freeze?

Since the first is still transmitting, it isn't totally dead. It leads me to believe it has received something and gone to some state that is freezing the screens. Or it is waiting on something before transitioning.

Nothing specific here, sorry.

Hi,

Sara, forget what I wrote to you in e-mail. Come to Think about that I fixed one bug also!
The displays are depentant of data from each other and in one of the recieving events I have managed to do an infinite loop. :)
Sorry for confusing you but the config is getting very complex at the moment so it is easy to miss a small error like that.

Thanks, Joakim
