NMEA 2000 Device Prioritisation
When there is more
than one device of the same type (like a GPS) on the NMEA 2000 network,
the
NGW-1 will use the data from the highest priority (lowest source
address). If the device you'd rather
use as a secondary Talker for the NGW-1 claims a lower source address
then unfortunately there is no easy way to change this. The first step
would be to try changing the device instance of the secondary Talker to
'instance 1' (leaving the primary at 'instance 0').
