MX510/MX512 Operator & Installation Manual - Simrad Professional ...

WPL - Waypoint Location Data Record:
The MX51x outputs all of the waypoints in the active route. If you want to output the
complete Waypoint Bank, simply highlight the Send All softkey then press ENT
from the NMEA WPL screen.
The WPL record, as defined by the NMEA 0183 standard, technically does not
allow the output of waypoint descriptions when interfacing to other devices such
as Chart Plotters. However, MX Marine realizes that with 2000 waypoints, you
have spent a lot of time preparing your library of waypoints with definitions and
symbols. You probably will want to record these to a PC or USB memory stick,
just in case the memory in the MX51x fails in the future. For this reason, we have
provided you the option to Include Waypoint Names in the WPL record to save
your waypoints or to meet the NMEA 0183 standard for interfacing to other marine
equipment. The definition of the differences between these two formats is given
in the WPT section of this manual and in the NMEA 0183 format section in the
Installation section of this manual.
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 function 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
MX51x 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 MX51x 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 pressing ENT (displayed during the alarm condition),
these data fields will revert to Valid data and the autopilot will accept the MX51x
data again. This is provided as a safety feature so that the boat does not turn
toward a new direction without you 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 MX51x 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.
