GENERAL INTRODUCTION TO B&G NETWORKThe B&G Network range of instruments is designed to beused as individual units or connected together to form anintegrated navigational system. A single network cable isused to carry data and power between units. The latesttechnology and screened cables throughout the NetworkSystem ensure the ultimate protection from interferencebetween units and other systems. All Network instrumentscan be linked to Network PILOT, Network CHART, NetworkGPS or Network LORAN receivers or via NMEA 0183 (v1.5)to other navigational equipment.INSTRUMENTSNAVIGATIONAL AIDSNetwork SPEEDNetwork DEPTHNetwork QUADNetwork WINDNetwork TACKNetwork DATANetwork GPSNetwork LORANNetwork NAVNetwork CHARTAUTOPILOTSCOMMUNICATIONSNetwork PILOTNetwork VHFHB-0502-032

INTRODUCTION TO NETWORK WINDNETWORK WIND DISPLAY UNITThe Network WIND unit measures and displays wind0information on an analogue 360 Apparent Wind Angle meterand a back-lit Liquid Crystal Display (LCD). The five keysallow selection of the information displayed on the LCD andsetting of the units mode, Wind Sensor offset calibration anddisplay damping.It can operate as the main Network WIND unit either alone oras part of an Intregrated Network Instrument System takinginputs directly from a Wind Sensor which plugs into the socketat the rear of the display, or as a repeater of wind informationreceived via the two Network cable tails. For true windfunctions Network WIND must be connected to a system thatcontains a Network SPEED or Network QUAD unit as boatspeed is required.The unit is able to transmit NMEA 0183 v1.5 data via thenetwork cables to other Network units and connect to anNMEA device e.g. a position fixer, with a special NMEA outputcable.The unit has no internal alarm or alarm functions.IMPORTANT NOTEYour Network WIND unit must be setup and calibratedcorrectly before it is used as part of a navigational system.HB-0502-033

EXAMPLES SYSTEMS USING NETWORK WINDOnly one Network WIND unit should have a wind sensorconnected to it and set to transducer mode. Up to three moreNetwork WIND units can be connected on to the systemnetwork, these must be set to repeater mode.See SELECTING THE DISPLAY MODE. For True windfunctions the Network WIND must be part of a systemcontaining Network SPEED or Network QUAD.QUADWind SensorQUADWINDMaster UnitNetwork SPEED, Network DEPTH, Network WIND andNetwork TACK (magnified wind angle).WINDRepeaterWINDTACKWINDRepeaterThe Network units can be connected together in any order asdata is shared via the system network cable link.DepthHB-0502-03Speed4

SELECTING THE DISPLAY MODEThe Network WIND unit has three operating modes.The correct mode must be selected for your Networksystem to operate correctly.tuUnit mode, the unit uses and displays wind data from awind sensor connected directly into the display unit. Your unitis supplied in this mode.trRepeater mode, the unit operates as a wind repeaterusing data from the system network.tdDemo mode, the unit runs an internal demonstrationprogram.Press SETUP key 4 timesto display current mode.HB-0502-03Press ENTER key if themode needs to bechanged. The displayflashes.Use ¿ or À key tochange the mode.Press ENTER key tomemorise the new mode. After30 secs the display will revertto previously selected display.5

THE ANALOGUE DIAL AND POINTERUSING THE APP. KEYThe analogue pointer always indicates Apparent Wind Angle00on the 360 dial. Each division marker is at 30 intervals. TheLCD is offset to the left so when running with the wind asternthe wind angle can still be read clearly.Press the APP. key to display Apparent Wind Speed on theLCD. The LCD APP legend will be displayed.HB-0502-036

USING THE TRUE KEYUSING THE VOLTS KEYPress 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 blankand the TRUE legend will be displayed.Press the VOLTS key to display Battery Volts on the LCD.The LCD V legend will be displayed.HB-0502-037

USING THE SETUP KEYPress the SETUP key to cycle through the following optionson the LCD.dSDamping Speed, this is the response time of the LCDwind speed display.dADamping Analogue, this is the response time of theanalogue pointer.OFOffset, this is the offset calibration value to correctfor Wind Sensor misalignment.tuDisplay mode, this is the operating mode of the NetworkWIND unit.HB-0502-038

LCD WIND SPEED DAMPINGThe wind speed damping allows the response time of theLCD wind speed display to be slowed down if the values areto jumpy in gusty conditions. The damping works byaveraging the wind speed over a set time period, the longerthe time period the smoother the displayed values, howeverthe 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 unitis supplied with a factory set value of d4.HB-0502-039

Press SETUP keyonce to display dS,damping Speed.HB-0502-03Press ENTER key todisplay currentdamping speed. Thedisplay flashes.Use ¿ or À key tocycle through thedamping values.Press ENTER key tomemorise the new value.After 30 secs the displaywill revert to previouslyselected display.10

ANALOGUE POINTER DAMPINGThe analogue pointer damping allows the response time ofthe analogue display to be slowed down if the values are tojumpy in gusty conditions. The damping works by averagingthe wind angle over a set time period, the longer the timeperiod the smoother the displayed values, however the longerit 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 unitis supplied with a factory set value of d1.Press SETUP keytwice to display dA,damping Analogue.HB-0502-03Press ENTER key todisplay currentdamping speed. Thedisplay flashes.Use ¿ or À key tocycle through thedamping values.Press ENTER key tomemorise the new value.After 30 secs the display willrevert to previously selecteddisplay.11

WIND SENSOR MISALIGNMENT CORRECTIONFor accurate wind angle readings the wind sensor should bepointing forward and aligned with the centreline of the boat.However, this is not always possible, so Network WINDallows a wind sensor offset value to be entered tocompensate for the misalignment electronically.Firstly the amount of misalignment must be found. Thefollowing procedure will enable you, during the course of asea trial, to establish the value.3 Determine the direction of the misalignment and windsensor offset value by subtracting the Starboard value fromthe Port value, then dividing by two. e.g. Port 35 - Starboard25 10 2 5.If the value is positive the misalignment is to Port, if thevalue is negative it is to Starboard.4 Enter the wind sensor offset value into the NetworkWIND unit's memory by following the procedure below.1 Sail close-hauled on a Port Tack, note the set of all thesails.When the conditions are steady, note the apparent wind angle0(AWA) on the analogue display, e.g. Port 35 .5 The alignment procedure should be repeated until thedisplayed AWA is equal on both tacks.NOTE: If you have Network TACK or Network DATA theAWA can also be read from these.2 Turn the boat until close-hauled on a Starboard Tack,make sure the sails are set as for the Port Tack.When the conditions are steady, note the AWA on this0e.g. 25 .HB-0502-03tack,12

ADJUSTING THE WIND SENSOR OFFSETIf the value calculated is positive, the wind sensor ismisaligned to Port. To correct this the analogue pointer mustbe offset clockwise (towards starboard) by the valuecalculated. Use the ¿ key (up) to change the value displayedon the LCD.If the value is negative, the wind sensor is misaligned toStarboard. To correct this the analogue pointer must be offsetanti-clockwise (to port) by the value calculated. Use the À key(down) to change the value displayed on the LCD.Press SETUP key 3times to display OF,OFfset value.HB-0502-03Press ENTER key todisplay current value.The display flashes.Factory set to zero.Use ¿ or À key toadjust the value.¿ clockwiseÀ anti-clockwise.Press ENTER key tomemorise the newvalue. After 30 secsthe display will revert topreviously selecteddisplay.13

USING THE LIGHTS KEYThe Network WIND Display unit has 3 levels of illuminationand off, controlled by the LIGHTS key. The level selected isfor the whole Network system. L0L3L2L1OFFHighMediumLowThe LIGHTS key also changes the illumination level of thekey legends, it always remains illuminated so even incomplete darkness the key can be located.HB-0502-0314

INSTALLATIONMOUNTING THE UNITThe display heads are supplied with a clip-in mountingbracket which allows for easy installation, access from behindis not necessary to secure the unit in place. However toprevent theft and permanently fix the unit in position, lockingstuds and thumb nuts are supplied.Use the cutting template supplied to mark the centres of theholes for the self-tapping screw, the fixing stud holes and themounting bracket.SITING THE UNITAll Network Instruments are designed for mounting on orbelow deck. A mounting position should be selected wherethey are: Easy to read by the helmsman On a smooth and flat surface At least 100mm (4") from a compass Accessible from behind for fitting locking studs ifrequired.HB-0502-03 The template allows 4mm (5/32") between adjacentunitsfor the suncover, increase this distance if required tomaximum of 60mm (2 3/8") between units or180mm(3 1/8") between centres. For greater distances betweenunits extension cables are available. Use a 70mm (2 3/4") diameter hole-cutter for themounting bracket hole. Use a 2.9mm for the self-tapping screw holes. Use a 5mm (3/32") drill for the locking stud holes. Secure the mounting bracket to the bulkhead with theself-tapping screws supplied Fit the rubber sealing gasket around the mountingbracket. Screw the locking studs into the back of the displayhead(if required). Carefully pass the cable tails through the mountingbracket hole, connect the cables to the main units.
