Approach Distance:
Sets the waypoint approach alarm distance (above) to sound if
your position is within the radius defined. The default setting is
0.30 Nm. This is a convenient tool for large boats and ships that
need to perform Transfer and Advance maneuvers prior to reach-
ing the waypoint.
Autopilot Alarm:
Causes an alarm when your position is outside the cross-track
error limit defined in
XTE Limit
(above) or when you change course
to a new leg in your route (manually or automatically passing a
waypoint) when
Yes
is selected. It also causes the NMEA data
records of APA, APB, and XTE to change their reported status of
Valid
to
Invalid
when you reach the waypoint of the current leg.
This tells the autopilot not to use the data from the receiver. When
the alarm is canceled, which requires your depression of the
Can-
cel Alarm
softkey (displayed during the alarm condition), these
data fields will revert to valid data and the autopilot will accept the
receiver data again.
This is provided as a safety feature so that the
boat does not turn toward a new direction without your knowing
of the impending change.
To disable the alarm, select
No
(the de-
fault condition) with the
Change
softkey.
NMEA Out 1 through n* - NMEA 0183 Output Data Control
These screens set the specific NMEA 0183 output record parameters
as well as the port control. The default setting is
No
. When this selec-
tion is changed to
Yes
, you can turn on individual data records. Refer
to the installation manual of the device you interfaced with the re-
ceiver to determine which output records are required. Refer to the
Installation & Service Manual
for receiver hardware interface infor-
mation.
* The number of user NMEA ports available depends on the model of

proprietary port (NMEA3) dedicated to the MX Marine smart
antenna.
MX420/8/AIS Model

two antenna ports (NMEA3 & 4) dedicated to the MX421 or
