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 speci-
fied 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
