Chapter 12 KGP-920
Communication with external navigation system
12.2 Route data transfer
Only a single route date can be transferred to KGP-920.
Route data should consist of a combination of $--RTE (Route) and $--WPT (Waypoint) sentences
specified by IEC61162.
Maximum number of characters including checksum in a RTE sentence line is limited to 124 bytes.
Route data can be two kinds of data, a Complete route or a Working route. A Complete route can
contain 100 waypoints ( waypoints excess of 100 are ignored) while a Working route can contain 9
waypoints and the last passed over waypoint (waypoints excess of 9 are ignored).
In EXT. mode, working route has priority over other functions including route navigation. When
KGP-920 receives a Working route data, it automatically goes into Working route navigation.
Maximum waypoint storage capacity is for 400 points combined with both NORMAL and EXT. modes.
12.2.1 Complete route transfer
When KGP-920 receives a Complete route data, “OVERWRITING last sent route” is indicated and then
it indicates “LOADED ext. route” to notify the route was successfully transferred.
When consecutive more than single routes are received. It indicates “INVALID ext. route” and voids
received data but the previously loaded route data remains and valid.
KGP-920 judges data transfer is ended when more than 10 second interruption of data transfer occurs.
The Complete route is stored as number 19
th
route.
