AUTOHELM ST 50 plus - Operation with a Navcenter

3 .8 Operation with a Navcenter
The Navcenter is a much simpler and more powerful way of setting
waypoints and routes . This is due to its ability to display them graphically
on an electronic chart .
For this reason, all waypoints and route planning should be done on a
Navcenter whenever there is one included in the system
.
When a Navcenter is included, the ST50 Plus GPS/Navdata should be set
to REPEAT mode (refer to Chapter 5, Calibration) .
In REPEAT mode the waypoint display and enter functions of the GPS/
Navdata are turned off . The SeaTalk system then uses the
waypoints and
routes set on the
Navcenter . The GPS/Navcenter TRACK key can then be
used to control the Navcenters track functions as follows :
1 .

Put the Navcenter onto track control
Track may be re-defined at any time from the vessels
current
position
to
the target waypoint by a
single press
of the
TRACK key . This will reset
cross track error to zero .
2 .

Advance Navcenter to the next waypoint
To advance the Navcenter to the next waypoint in a route, press and hold
TRACK on the GPS/Navdata for 1 second .
