Nav4 - Sensor Input Navigation - Leica MX400 Operating Instructions Manual

Navigate
You will find the right hand window to be a nice tool. In addition to
identifying the waypoint you are currently approaching, it identifies
the waypoint at the end of the next leg as well. But the really unique
feature of this screen is the graphical representation of your actual
course line approach angle relative to the next leg of your course.
This approach angle is continuously updated in real time and will
help you setup for course changes.
Reset XTE and Skip Waypoint, described at the end of NAV2, is
also available in NAV3.

NAV4 - Sensor Input Navigation

The NAV 4 screen applies the wind instruments, speed log, com-
pass, and depth sounder inputs from external sensors to your active
route, as appropriate. You can set the sensors up in the CFG1
screen. The Installation & Service Manual will guide you through
the interfacing capabilities of the receiver.
Use the following CFG1 menus to set this screen up:
Compass - Sets the input port number, compass type (true or
magnetic), compass deviation table, and the input NMEA 0183
record to derive the compass information from. The NMEA
0183 record should be specified by the user, because several
NMEA 0183 records may contain compass information. This
provides you the capability of knowing exactly what the
compass source is. The receiver only accepts NMEA 0183
formatted data for the compass input. If you have a synchro or
stepper gyro compass, we offer a Smart Junction Box (SJB)
option to convert these signals to the NMEA 0183 format.
Details of the SJB are given in the Configuration section of this
manual, and in the Installation & Service Manual.
Depth - Sets the input port number, units of measure for depths and
Tide data, sensor offset, alarms, and the input NMEA 0183
record to derive the depth information from. The NMEA 0183
record should be specified by the user, because several NMEA
0183 records may contain depth information. This provides you
the capability of knowing exactly what the depth source is.
