Application Note 2
Driving the Robertson Dataline X Central Display with Portable Navigator.
Portable Navigator's ability to manage routes and waypoints is no longer confined to the navigation table! If the vessel has a Dataline X system - CENTRAL display unit, fitted in the cockpit, then the SOG, COG, XTE, waypoint number, range and bearing, from portable navigators NMEA output, can all be monitored without going below. Coupled with automatic waypoint changing and route reversal facilities of portable navigator this provides useful hands off feedback to the helmsman.
- Use portable Navigator to average the SOG and COG over required time interval
- Steer to make the COG and BRG equal to eliminate cross tide effects
- Use the XTE display to monitor drift from intended course
- Instant new course update to helmsman when waypoint changes
To connect Portable Navigator to a Dataline system use the aux NMEA input on the databox via a NMEA - RS232 convertor cable. Portable navigator can then output the appropriate sentences to drive the Dataline X system.
Portable Navigator can also take other NMEA data from the Dataline X , e.g.
depth, windspeed etc., in DataLine X proprietory NMEA format, which can be logged to a text file.
