8 NAVIGATE MODE§
Navigate Mode is only available if there is a GPS or other source of NMEA 0183 data
connected to the NAV6 NMEA input.
The GPS icon in the status bar at the top of the display will be illuminated only if there
is position data available on the NMEA input.
There are five fixed-format Navigate data display views and four user configurable
views. These can be selected from within the Navigate Mode using the VIEW softkey.
The five fixed views are:
Position View
Combined View
Waypoint View
Conning View
Log View
The User Configurable Views are User Views 1,2,3 and 4.
(Tip: Disable views that are not required, in [Setup Mode ⇒
⇒⇒
⇒ Navigate ⇒
⇒⇒
⇒ Options Page
and Setup Mode ⇒
⇒⇒
⇒ Navigate ⇒
⇒⇒
⇒ User View Page]. Display units can be changed in the
Navigate Options page).
Note: Data fields that are not available on the NMEA input are indicated by a series of
dashes (e.g. ---.--).
Important
The correct magnetic variation must be input at the navigation instruments (e.g. GPS,
electronic compass) for the accurate display of COG, set, waypoint bearing and
heading.
For the purposes of testing your installation, you may wish to use your GPS’s
simulator mode to generate data for the NAV6. Please check your GPS User Manual
to find out whether it transmits valid NMEA data whilst it is in its simulator mode –
many GPS’s do not set the ‘data valid’ flag in the NMEA sentences during simulation.
As a safety feature, the NAV6 will ignore any NMEA sentences where the ‘data valid’
flag is not set.
The NAV6 has a built in NMEA simulator mode – please ensure that it is switched
OFF in normal operation.
