horizon. In other instances where high-precision fixes are nec-
essary, the advanced user can modify this option to “hide” any
low satellites, thereby preventing their use as sources of GPS
position information, and avoiding potential errors.
If needed, this option is adjustable from 0° to 25°, in 5° incre-
ments. Northstar recommends that this option be left at the
factory setting of 10°.
To change this option, press the
menu key, then press

Changing port setup options
You can connect (or “interface”) the unit directly with a variety
of external devices, such as autopilots, radars, depth sounders,
computers, and so on. You also can connect one unit to
another (for example, connect two 952s, two 951s, a 951 and a
952, or either a 951 or 952 with a Northstar 941), so that two
or more units can “share” all the same waypoints and routes.
Depending on the device, connection is made through any of
three data transmission “ports” located on the back side of the
unit: two NMEA ports and one RS-232 port. Each is capable of
operating independently, thereby giving you the flexibility of
controlling three separate devices simultaneously. The ports
are also independently configurable to meet the specifications
of most peripheral navigation equipment. This ensures a cus-
tomized setup for virtually any NMEA 0183-compatible device.
Once configured, the unit continuously sends a stream of data
to the device(s).
To access the unit’s port setup options, press the
