Change GP330B PGN update frequency

[Wdeertz]

I have a SCX20 as my primary position/heading sensor but have a GP330B on my n2k network as a backup. I've rationalized the PGN update frequency for the SCX20 directly on my TZTBBX. My n2k network has many devices and often gets too busy with bus errors. As such I'd like to update the PGN frequency send frequency for the GP330B but can't find a way to do this. How can the GP330B PGN update frequency be altered?

No they can't be changed. Unless you have a massive bus exceeding the 50 device limit by NMEA, the bus errors are not likely related to the rate you are having data go to the bus. I would look for noise. Last boat I had with lots of bus issues had a LED spot light cable running across the NMEA 2000 cable and noise was inducting into the bus. Motors, pumps, other power cables, there are many sources of noise on boats unfortunately. Bus issues can be a real challenge.
