any information you like here, such as the date the unit was installed, or the location in which it was

6.3.1.10 NMEA2000 PGN Enable/Disable
The ACM100 Alternating Current transmits a number of the NMEA2000
®
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 45).
