9 N2KView

This section details the configuration and operation of the N2KView station

component of the N2KView System.

9.1 General Concepts

9.1.1 Touch Screen Operation

N2KView was designed so that all functions in operational mode can be

performed with either a mouse or a touch screen. It is still required to have a

mouse and a keyboard to perform configuration of N2KView.

9.1.2 Keyboard Operation

A keyboard is required to configure N2KView. There are a number of fields that

need to be entered with text. In normal operation, if a keyboard is connected,

short cuts can be used to easily navigate from screen to screen.

In case there is no keyboard connected to the computer, a virtual keyboard will

be displayed on the screen the first time there is a need to enter textual data.

Pressing a key on a physical keyboard will remove the virtual keyboard from the

display. If you are using a physical keyboard, and then unplug the physical

keyboard, this action cannot be detected by the program and the virtual keyboard

will not appear. The program needs to be restarted to enable the virtual keyboard

again.

9.1.3 Parameters

The key concept of N2KView is the display of parameters. A parameter is a piece

of information about some function of the vessel. The parameter is defined by a

particular data type, such as engine speed or barometric pressure, and possibly

also by a particular instance of that data type; for example, the speed of the Port

Engine.

All of the available parameters that N2KView can display are listed in Section 9.6

on page 162. A device is required to be connected to the NMEA 2000 bus and

producing the relevant data for it to be displayed.

9.1.4 Components

Each parameter may be displayed by a component. A component is a graphical

display that is generally dedicated to the display of the value of a parameter.

Examples of components include the digital display, a gauge, and a bar graph. A
