I did not understood, what you mean - that was already on library. Anyway I found that values should be signed, so I have to fix the code to handle that right.

Also you have N2kMsg.Priority=3; Where did you got that? I do not have document for right send period and priority. So if you have certified device, which sends that PGN, please report, what priority and send period it uses.

I am terribly sorry about opening this becouse i didnt checked your latest code. I wrote this code more then a year ago and decided to share but little after i noticed that you have wrote it allready. And i a m new to github and i didnt know how to delete this so is that i tried closing this as an issue.

[ttlappalainen]

That is OK. Anyway I'll fix handling within few days. I'll leave this open and inform, when I have done it.

And what about my question of priority and update speed?

http://forum.katera.ru/index.php?app=core&module=attach&section=attach&attach_id=135641 as far as i remember i have looked at here and https://www.maretron.com/support/manuals/USB100UM_1.7.pdf then i have examined your code and wrote it. I am no expert about NMEA bus, just trying to digitize my analog devices on my boat thanks to your source libraries.

This works right, except in case that for some reason send data length would be less than expected. In that case it will not return NA. I'll close this and fix it some day. There are other PGN:s, which has same problem.
