GENERAL INTRODUCTION TO B&G NETWORK The B&G Network range of instruments is designed to be used as individual units or connected together to form an integrated navigational system. A single network cable is used to carry data and power between units. The latest technology and screened cables throughout the Network System ensure the ultimate protection from interference between units and other systems.

INTRODUCTION TO NETWORK TACK NETWORK TACK DISPLAY UNIT The Network TACK unit is a analogue Magnified Wind Angle repeater used for sailing on the wind or running, with a backlit Liquid Crystal Display (LCD) that can show other wind information selected by pressing one of the five keys. It has no sensor interfaces as all data is passed to the unit via the system network cables.

EXAMPLES SYSTEMS USING NETWORK TACK Network QUAD, Network WIND and Network TACK units. Speed data being supplied from the Network QUAD unit for true wind and VMG functions. Network SPEED, Network DEPTH, Network WIND and Network TACK. Speed data being supplied from Network SPEED unit for true wind and VMG functions. The Network units can be connected together in any order as data is shared via the system network cable link.
PAGE 5
USING THE ANALOGUE DIAL AND POINTER The analogue pointer indicates magnified apparent wind angles up to 500 port or starboard when close hauled or running. EXAMPLE SAILING DOWNWIND EXAMPLE SAILING UPWIND Network WIND shows an AWA of about 30° to Port, relative to the bow. Network TACK shows an AWA of 35° to Port, relative to bow. The LCD is showing an AWS of 10 knots. The LCD is showing a TWA of 66°. Network WIND shows an AWA of about 150° to Starboard, relative to the bow.

USING THE AWA KEY USING THE TWS KEY Press the AWA key to display Apparent Wind Angle on the LCD. The LCD APP legend will be displayed. Press the TWS key to display True Wind Speed on the LCD. The LCD TRUE legend will be displayed. If boat speed data is not available the LCD digits will be blank and the TRUE legend will be displayed.
PAGE 7
USING THE TWA KEY USING THE VMG KEY Press the TWA key to display True Wind Angle on the LCD. The LCD TRUE legend will be displayed. Press the VMG key to display Velocity Made Good on the LCD. The LCD V legend will be displayed. If boat speed data is not available the LCD digits will be blank and the TRUE legend will be displayed. If boat speed data is not available the LCD digits will be blank and the V legend will be displayed.

USING VMG FOR BETTER PERFORMANCE VMG is an indication of how efficiently the yacht is sailing upwind or downwind. Maximising your VMG ensures you are following the fastest route upwind or downwind. USING THE LIGHTS KEY The Network TACK Display unit has 3 levels of illumination and off, controlled by the LIGHTS key. The level selected is for the whole Network system.
PAGE 9
INSTALLATION MOUNTING The display heads are supplied with a clip-in mounting bracket which allows for easy installation, access from behind is not necessary to secure the unit in place. However to prevent theft and permanently fix the unit in position, locking studs and thumb nuts are supplied. Use the cutting template supplied to mark the centres of the holes for the self-tapping screw, the fixing stud holes and the mounting bracket.

ABBREVIATIONS AND DEFINITIONS AWA Apparent Wind Angle - The angle between the boat's bow and the wind blowing across the deck (at mast height). AWS Apparent Wind Speed - The wind speed across the deck (at mast height). TWA True Wind Angle - The wind angle between the boat's heading and the true wind (at mast height). This is calculated from AWA, AWS and boat speed. This is the wind relative to the water, not the land.
