Factory Default Output Messages

The factory default for the SF-3050 is to output 8 NCT messages via COM1 and USB1, and 3
NCT messages on all ports (see Table 6). The user has full control over the utilized message
types and their associated rates.

NMEA messages are not output by default. They must be scheduled by the user
via a user profile or the Input Terminal. Use the NMEA tab to view the scheduled
NMEA messages (see Figure 128).
