Configuration
Other Special Cases Affecting NMEA 0183 Records:
BWC, BWR, APA, APB, RMB, RMC, and Man Over Board (MOB):
APA, APB, XTE, and the Navigation Autopilot Alarm:
Output Port Configuration Conflicts:
Version 3.0
During the period when the Man Over Board function is activated,
NMEA 0183 records which contain bearing and range data, such as
those identified above (but not limited to these), will reflect the
bearing and range back to the MOB position until the MOB func-
tion is canceled. Refer to the MOB section of this manual.
Refer to the CFG Navigation section. When the Autopilot Alarm
is set to No, the receiver always indicates a mode 'A', or valid data
to the autopilot or other marine device which might be receiving
this data. If the Autopilot Alarm is set to Yes, then the receiver
changes the mode 'A' to 'V', indicating invalid data when you
reach a waypoint or exceed your cross-track error limit set in the
CFG Navigation XTE Limit field. When the alarm is canceled, which
requires your highlighting of the Cancel Alarm softkey then press-
ing ENT (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.
The NMEA output ports can only be assigned once. If you have
already defined a given port for one format, and you attempt to
define a different format for the same port, the receiver will warn
you of the port conflict. The first format to be defined on a port
maintains the port. The second format will be ignored.
