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 WIND NETWORK WIND DISPLAY UNIT The Network WIND unit measures and displays wind 0 information on an analogue 360 Apparent Wind Angle meter and a back-lit Liquid Crystal Display (LCD). The five keys allow selection of the information displayed on the LCD and setting of the units mode, Wind Sensor offset calibration and display damping.
EXAMPLES SYSTEMS USING NETWORK WIND Only one Network WIND unit should have a wind sensor connected to it and set to transducer mode. Up to three more Network WIND units can be connected on to the system network, these must be set to repeater mode. See SELECTING THE DISPLAY MODE. For True wind functions the Network WIND must be part of a system containing Network SPEED or Network QUAD.
SELECTING THE DISPLAY MODE The Network WIND unit has three operating modes. The correct mode must be selected for your Network system to operate correctly. tu Unit mode, the unit uses and displays wind data from a wind sensor connected directly into the display unit. Your unit is supplied in this mode. tr Repeater mode, the unit operates as a wind repeater using data from the system network. td Demo mode, the unit runs an internal demonstration program. Press SETUP key 4 times to display current mode.
THE ANALOGUE DIAL AND POINTER USING THE APP. KEY The analogue pointer always indicates Apparent Wind Angle 0 0 on the 360 dial. Each division marker is at 30 intervals. The LCD is offset to the left so when running with the wind astern the wind angle can still be read clearly. Press the APP. key to display Apparent Wind Speed on the LCD. The LCD APP legend will be displayed.
USING THE TRUE KEY USING THE VOLTS KEY Press the TRUE 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. Press the VOLTS key to display Battery Volts on the LCD. The LCD V legend will be displayed.
USING THE SETUP KEY Press the SETUP key to cycle through the following options on the LCD. dS Damping Speed, this is the response time of the LCD wind speed display. dA Damping Analogue, this is the response time of the analogue pointer. OF Offset, this is the offset calibration value to correct for Wind Sensor misalignment. tu Display mode, this is the operating mode of the Network WIND unit.
LCD WIND SPEED DAMPING The wind speed damping allows the response time of the LCD wind speed display to be slowed down if the values are to jumpy in gusty conditions. The damping works by averaging the wind speed over a set time period, the longer the time period the smoother the displayed values, however the longer it takes to see any change. Network WIND allows selection of four damping values, d1, d2, d4, d8, each is the approximate time in seconds. The unit is supplied with a factory set value of d4.
Press SETUP key once to display dS, damping Speed. HB-0502-03 Press ENTER key to display current damping speed. The display flashes. Use ¿ or À key to cycle through the damping values. Press ENTER key to memorise the new value. After 30 secs the display will revert to previously selected display.
ANALOGUE POINTER DAMPING The analogue pointer damping allows the response time of the analogue display to be slowed down if the values are to jumpy in gusty conditions. The damping works by averaging the wind angle over a set time period, the longer the time period the smoother the displayed values, however the longer it takes to see any change. Network WIND allows selection of four damping values, d1, d2, d4, d8, each is the approximate time in seconds. The unit is supplied with a factory set value of d1.
WIND SENSOR MISALIGNMENT CORRECTION For accurate wind angle readings the wind sensor should be pointing forward and aligned with the centreline of the boat. However, this is not always possible, so Network WIND allows a wind sensor offset value to be entered to compensate for the misalignment electronically. Firstly the amount of misalignment must be found. The following procedure will enable you, during the course of a sea trial, to establish the value.
ADJUSTING THE WIND SENSOR OFFSET If the value calculated is positive, the wind sensor is misaligned to Port. To correct this the analogue pointer must be offset clockwise (towards starboard) by the value calculated. Use the ¿ key (up) to change the value displayed on the LCD. If the value is negative, the wind sensor is misaligned to Starboard. To correct this the analogue pointer must be offset anti-clockwise (to port) by the value calculated. Use the À key (down) to change the value displayed on the LCD.
USING THE LIGHTS KEY The Network WIND Display unit has 3 levels of illumination and off, controlled by the LIGHTS key. The level selected is for the whole Network system. • • • • L0 L3 L2 L1 OFF High Medium Low The LIGHTS key also changes the illumination level of the key legends, it always remains illuminated so even in complete darkness the key can be located.
INSTALLATION MOUNTING THE UNIT 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 THE WIND TRIANGLE 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.
