NMEA Setup
To prepare the unit to support an NMEA device, press AUX 6. Follow
the message prompts to activate the dataport and select the output
message that is required by your equipment. (See page 5-9.)
Activating NMEA Support
The unit supports NMEA devices only when it is in continuous opera-
tion (Battery Saver off or using external power), the dataport is on,
output has been activated by pressing POS, NAV, or VEL, and position
fixes are being obtained.
Do not turn the external device on until you are sure the unit is
emitting data. Data is emitted only after the unit has obtained its first
fix (usually within 1 minute), and is then updated every 2 seconds.
Successful NMEA support of external devices requires that the follow-
ing parameters be set:
o
cables are connected
o
unit is ON
o
route is set
o
unit is operating with Battery Saver off or from extemal power
o
dataport is on and set to a message output acceptable to your
device
o
external device is turned on
o
unit is getting position fixes
ENTERING DATA

keypad to enter an initial position, to manually enter a waypoint, or to
