48 | Keypad & Display Description

The CDU outputs these sentences in the following format:

Rnn - Routes:

Waypoint identifiers, listed in order with starting waypoint first, for route number “nn”. The

active route in the CDU is always route zero, but in the Rnn sentence the route number can

be transmitted as either route 00 or 01.

Rnn is NMEA version 1.5. Use of GPRTE is recommended to comply with NMEA version

2.1.

field#: 1 2 3 4 1 1 1

4 5 6

$GPRnn,cccc,cccc,cccc,.....,cccc,cccc*hh<CR><LF>

Explanation / actual use:

1: nn = active route number, 00 or 01

can be set to 00 or 01 (default 00).

2 - 15: 14 field sequence of route waypoint IDs.

16: Checksum can be set on or off (default on).

RTE - Active Route:

Waypoint identifiers, listed in order with starting waypoint first, for the identified route.

Two modes of transmission are provided: “c” indicates that the complete list of waypoints

in the route are being transmitted; “w” indicates a working route (active) where the first

listed waypoint is always the last waypoint that has been reached (FROM), while the second

listed waypoint is always the waypoint that you are currently heading toward (TO). The

remaining list of waypoints represents the remainder of the route.

RTE can be sent as version 2.1 and 2.0.

field#: 2 3 4 5 6 1 1 1

5 6 7

$GPRTE,x,x,a,cccc,cccc,.....,cccc,cccc*hh<CR><LF>

Explanation / actual use:

2: Total number of messages being transmitted (a single route may require

the transmission of multiple messages). A maximum of 11 waypoints are

transmitted in each messages.

3: Message number.

4: Message mode: c = complete route, all waypoints, w = working , 1

listed

waypoint is ‘FROM’, 2

is ‘TO’ and remaining are the rest. c/w can be set to c

or w (default w).

5: Route identifier, always 00 (Active Route only).

6 - 16: Waypoint identifiers, (less than 11 waypoints may be in the message).

The number of remaining waypoints can be set to 1, 2 or “all” (default all)

shortening the drawn track on the plotter.

17: Checksum can be set on or off (default on).

WPL - Waypoint Location - NMEA 0183 Standard:

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 conforms to the NMEA 0183 standard.

WPL can be sent as version 1.5, 2.0 or 2.1.
