Reference Manual Revision B
Northstar’s networking technology lets you connect two or more 972 units in order to share navigation data (including radar and sounder data) and all waypoints and routes between the units. The system can be operated from any connected unit, and all changes to routes and waypoints are reflected on all the networked units. Networking is fully automatic on the 972 — no special steps are necessary
One display unit is designated as the master, and all others as slaves. The only restrictions on networking are the following:
there must be one and only one master
unit operating in a network
all units must have the same software
version.
If, for example, a slave unit is turned on before the master, a message is displayed reminding you to turn on the master unit before using the slave. In case the master unit is not available (removed for service, for example), brief instructions show how to temporarily convert a slave into a master unit.
For details on networking, see Networking, starting on page 141.

Maintaining the 972

Basic maintenance

To help retain the 972’s best possible performance, Northstar recommends the following:
keep fingerprints off the display screen
(remove any prints with a lens cleaning cloth)
remove dirt and grime using a soft
cloth and Windex or soap and water
don’t scratch the display by wiping a
Pre-packaged moist towellettes (especially those containing a small amount of alcohol) are excellent for cleaning the display window. You might want to keep a supply on hand to wipe off fingerprints and other smudges.
sandy or salty cloth across it
use the 972’s protective plastic
sunshield when not in use (excessive heat from the sun can cause damage)
don’t open the 972 case—there aren’t
any user-serviceable parts inside
always keep the rear connectors’ plastic
caps on when they are not in use (the connectors are not waterproof unless covered)
nician should perform these installations. For details, contact your local authorized Northstar dealer.

Cleaning the display screen

Be careful when cleaning the glass window covering the display screen. Although the window is scratch-resistant, you may damage the anti-reflective coating if you use a dry cloth to wipe dirt off. Always use a damp cloth with plenty of water to remove salt or dirt. To remove any oil or grease on the screen, use a clean, dry microfiber-type lens cleaning cloth or a small amount of window cleaner.
Avoid touching the window with your fingers. The natural oils from your hand will temporarily affect the characteristics of the screen and cause your fingerprints to appear as bright reflections. Fingerprints will disappear when you clean the screen as described in the previous paragraph.

One of the 972’s unique features is the ability to display both raster and vector charts. In split screen mode, you can even display a raster chart and a vector chart side by side. This is a great way to under­stand the differences and similarities between the two.

Raster Charts

Raster charts are literally digital scans of paper charts. In most cases, these paper charts are issued by the local government. The scans, like digital photos, are a matrix of dots. The challenge in raster charts — the earth is round (3D) and the chart is flat (2D) — is to be able to determine the precise latitude and longitude of each dot at any zoom level.
One of the biggest benefits of raster charts is their appearance – it is identical to the
Getting Started
Electronic Charts and the 972
paper charts. It’s like having the paper chart on the screen.
This is also one of the drawbacks to raster charts. Since the chart is just a matrix of dots, the chart plotter cannot tell the differ­ence between a navaid and a depth sounding. Furthermore, they really only look great at one particular zoom level. Zooming in or out from that level compro­mises display quality.

Vector Charts

Vector charts, on the other hand, are drawn on the screen from a set of rules specific to each chart — instead of a digi­tized photo of the chart, it’s a mathematical description of the chart. The chart plotter interprets the description and then draws (renders) the chart. Whatever the screen resolution or zoom level, they always look great. Rather than being a
Northstar 972
matrix of dots, the vector chart is a series of lines and shapes. The shapes are then filled in with colors.
Another advantage is the ability to “layer” the data. The user can shut off certain layers so the display is less cluttered.
One of the biggest benefits of vector charts is that navaids and other points of interest are specified in the chart data, so the plotter can highlight navaids, and do intel­ligent things when the vessel or the cursor gets near a navaid. This increased flexi­bility is virtually boundless in the power it offers.

Purchasing charts

Purchasing charts for your 972 is quick and easy, because all available charts are

already stored on a hard disk drive in its processor module. There’s no waiting for delivery or visits to dealers — you only need to purchase a chart permit to use them.
To purchase additional charts:
One of the drawbacks of vector charts has been that they don’t look identical to the raster charts. With advances in technolo­gies – both in cartography and marine electronics – this disadvantage is disappearing.
See page 28 for more on charts in the 972.
In addition, a menu key for purchasing charts is displayed on the chart screen, whenever there are additional charts that you have not purchased, at the current vessel position.
1. Press the STAR key several times to display the Passport OnBoard screen.
2. Note the Passport OnBoard serial number, and contact Jeppesen Marine by telephone or the Internet to purchase the chart permits you need.
3. Enter the chart permit and press ENTER.
4. Wait for the chart to be activated (up to five minutes).

Quickstart Guide Revision B
The Northstar 972 can guide you directly to any point on the chart screen that you designate. “Point-and-shoot” navigation, as it is called, is often the easiest way to go to a waypoint or a series of waypoints: Just select the points right on the chart and go to them, one after another. This technique provides the most flexibility in deciding where you want to travel. Simply move the cursor wherever you want, press a key, and you’re navigating.

Using the alarms

The 972 has several alarms that automati­cally alert you to certain situations. For example, the 972 lets you know when you’re approaching a waypoint by sounding a beep and flashing an alarm icon on the screen. The icon explains the reason for the alarm. Most of the common alarms automatically cancel themselves after ten seconds or after the condition ends. For details, see Alarms, starting on page 132.
