WPL - Waypoint with Symbols & Description - NMEA 0183 Expanded:

Latitude and Longitude of specified waypoint. The content of this sentence will normally be

the position of the next waypoint in the route.

The CFG1 NMEA out WPL has a special “Send All” option. Selecting this feature will send

all the waypoints in the Waypoint Bank once independent of the WPL sentence setup as

ON or OFF. This format does not strictly conform to the NMEA 0183 standard, and may

not work with all equipment. It is provided for your use to store data on a PC using normal

ASCII text editors.

6. Waypoint identifier; 4 place numeric waypoint number, followed by 1 space,

followed by 10 characters for the top line of the description, followed by 10

characters for the bottom line of the description. When this field is output, you

may see spaces between the xxx and zzz. These are “fill characters” and are

necessary to fulfill the 10 character count to maintain character placement

when read back into the CDU.

Downloading Waypoints to a Personal Computer

You can use any terminal or communications program to download or upload waypoints

and routes to or from the CDU and a PC.

Set the PC to:

4800 baud 8 bits

1 stop bit no parity

no flow control

When sending data to the CDU, it must be sent in block form, followed by (with an appended)

CR (carriage return) and LF (line feed). Normal communications programs, like Windows

3.1 or 3.11 Terminal are sufficient to get the job done. Unfortunately, Hyperterminal in

Windows 95 doesn’t provide as simple a terminal emulation program as Windows 3.11, and

we have found it unreliable. We suggest that a third party terminal program be used with

Windows 95 (or higher).

Using Windows Terminal, do the following (from the Program Manager):

Connect the CDU’s port (1or 2) to the PC’s communications port (Refer to the

Appendix G of this manual).

On the CDU press the

2 CFG key.
