Uploading Waypoints from Other Devices
The CDU will accept waypoints from any device which follows the WPL formats identified
earlier in the Waypoint section. The first two characters following the $ can be any NMEA
defined talker ID. You do not have to calculate and include the checksum; however, you
must end each data record with a carriage return and line feed. If you do include the
checksum at the end of the data record, the CDU will verify the checksum. If the checksum
is invalid, the waypoint will be rejected.
Waypoints received on the data port will be stored to the waypoint location specified in
the WPL record. If the waypoint location specified in the WPL record is already occupied,
the CDU will overwrite the existing waypoint (if it is unlocked). If the existing waypoint is
locked, the WPL record received on the input port will be ignored and dropped.
The CDU will only recognize waypoints from one input port at any given time. This port is
defined in CFG1 => WPT & RTE In.
