1. 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 Wind Sensor 20 QUAD WIND WIND WIND Master Unit Repeater Repeater 135 F ag HB 0502 03 Network SPEED Network DEPTH Network WIND and Network TACK magnified wind angle QUAD WIND SPEED 625 125 6 155 ae UY pt p os 1 US a i la The Network units can be connected together in any order as data is shared via the system network cable link 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 usin2. note the set of all the sails When the conditions are steady note the apparent wind angle AWA on the analogue display e g Port 35 NOTE If you have Network TACK or Network DATA the AWA 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 this tack e g 25 HB 0502 03 3 Determine the direction of the misalignment and wind sensor offset value by subtracting the Starboard value from the Port value then dividing by two e g Port 35 Starboard 25 10 2 5 If the value is positive the misalignment is to Port if the value is negative it is to Starboard 4 Enter the wind sensor offset value into the Network WIND unit s memory by following the procedure below 5 The alignment procedure should be repeated until the displayed AWA is equal on both tacks 12 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 A 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 w key down to change the value displayed on the LCD Press SETUP key 3 Press EN
