Configuration
Other Special Cases Affecting NMEA 0183 Records:
BWC, BWR, APA, APB, RMB, RMC, and Man Over Board (MOB):
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.
APA, APB, XTE, and the Navigation Autopilot Alarm:
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 depression of the
Cancel 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.
Output Port Configuration Conflicts:
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.
