You make the connection through any of four data transmis-
sion ports located at the back of the 961: three NMEA ports
and one aux port. Each can operate independently, giving you
the flexibility to control four separate devices simultaneously.
The ports are also independently configurable to meet the
specifications of most peripheral navigation equipment, a fea-
ture that ensures a customized setup for virtually any NMEA
0183-compatible device. Once configured, the 961 will contin-
uously send a stream of data to the device(s).
For complete technical details about changing port setup
options to interface your 961 with other equipment, see the
Northstar 961 GPS Chart Navigator Installation Manual.
The DATABASE FUNCTION screen provides access to several
database maintenance options. To display these options, press
the STAR key until you reach the SERVICE MENU screen,
then press the DATABASES AND LOG key.
Saving and restoring a 961 database
You can easily save, or backup, your entire database of
user-defined waypoints and routes as well as your user prefer-
ences to either floppy or Zip disks. (User preferences are the
display, navigation, chart, receiver, and port-setup features of
your 961.) Because the 961 is sold with a standard 1.44-MB
floppy disk drive, to save these databases to a Zip disk rather
than to a floppy, you must order the optional 100-MB Zip drive
to replace the standard floppy drive of your 961.
After saving, you can then restore these databases back to the
961. Why save and restore? One, you may want to keep sepa-
rate sets of waypoints and routes for different cruising areas so
you won't have to sort through one large database of way-
points and routes to select the ones you want (even though
the 961's search function is always quick and easy). Two, if
you ever have to return the 961 to the factory for service, it's a
good idea to have a separate copy of your waypoints, routes,
and user preferences from the system's hard drive, since it's
possible that this information may be lost during repair.
