SYSTEM CONFIGURATIONS

All NavNet products incorporate a “network circuit board” to integrate each NavNet product on board through an optional LAN cable (Ethernet 10BASE-T). Each NavNet product is assigned an IP address to enable transfer of images between other NavNet products. For example, video plotter pictures can be transferred to a radar and vice versa. Pictures received via the NavNet may be adjusted at the receiving end.

The number of display units which may be installed depends on the number of network sounder connected. For a system incorporating three or more products, a “hub” is required to process data.

For one network sounder: one radar and three plotters, or four plotters For two network sounder: one radar and two plotters, or four plotters

Note: NavNet2 equipment cannot be connected to initial version NavNet equipment.

1. OPERATIONAL OVERVIEW

This chapter provides the basic information needed to get you started using your radar, video plotter.

1.1 Operating Controls

Display unit controls

The radar, video plotter, sounder and chart systems are operated with the controls of the display unit. Ten keys are labeled and they provide the function shown on their labels. The five soft keys provide various functions according to current operating mode. The ENTER knob mainly functions to register selections on the menu and adjust the EBL, VRM and gain. The Trackball’s main function is to move the cursor across the screen. When you correctly execute an operation, the unit generates a beep. Invalid operation causes the unit to emit three beeps.

Displays the mode selection window.

Momentary press:

1.3 Turning the Unit On/Off

Press the POWER/BRILL key to turn the unit on. A beep sounds and then the equipment shows the startup NavNet screen (about 20 seconds), the product information screen, startup test results and chart usage disclaimer. During this period the equipment is inoperative. The startup test checks the ROM, RAM, internal battery and backup data for proper operation, displaying the results for each as OK or NG (No Good). If NG appears an appropriate message appears on the screen. For any NG, try to press any key to go to the chart disclaimer screen, then perform the diagnostic test as shown in the paragraph “8.8 Diagnostics.”

For start up with the radar display, the magnetron takes from one minute and thirty seconds to three minutes (depending on radar model) to warm up before the radar can be operated. The time remaining for warming up of the magnetron is counted down at the center of the display.

You may press any key at the chart disclaimer screen to show the last-used display, or wait several seconds to let the equipment do it for you.

To turn the unit off, press and hold down the POWER/BRILL key until the screen goes off (approx. 3 sec.). To protect the LCD attach the hard cover. Note that the network sounder will be turned off approx. three minutes after turning off the power. This is due to the system’s electrical characteristics.

Note: The first time you turn on the power (or any time the power is applied after a memory reset), you are asked if you want to start the simulation mode, which provides simulated operation of the equipment after the installation mode selection. Push the ENTER knob to start the simulation mode, or press the CLEAR key to start normal operation. For further details about the simulation mode, see the paragraph “1.10 Simulation Display.”

The simulation display, for use by service technicians for demonstration purposes, provides simulated operation to help acquaint you with the many features your unit has to offer. It allows you to view and control a simulated plotter, radar and sounder picture, without position-fixing equipment, network radar or a network sounder. Most controls are operative, thus you may practice setting destination, enter waypoints, measure range and bearing to a target, etc. Three simulation displays are provided for both the radar and echo sounder.

The simulation icon (SIM) appears when any simulation mode is active.

To start the simulation display;
