PGNs which can be
turned on or turned off by the DSM250 display. For reasons of compatibility with older NMEA2000
devices, some of these PGNs are redundant; disabling these PGNs will reduce the amount of traffic
on the NMEA2000
®
bus. Pressing the Enter key with “NMEA2000 PGN Enable/Disable…” menu item
selected causes the DSM250 to display the following screen (Figure 214).
