GENERAL INTRODUCTION TO B&G NETWORK INTRODUCTION TO NETWORK QUAD 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 QUAD CONT'D NETWORK QUAD DISPLAY UNIT The Network QUAD unit has three adjustable alarms: 1. Shallow water alarm 2. Deep water alarm 3. Anchor alarm An internal alarm buzzer will sound when an alarm condition is met and the display will flash. The alarm is broadcast to all other Network Instruments in an integrated system, they will also sound their alarms and flash their displays (except Network WIND and Network TACK). The Network QUAD unit is NOT able to transmit NMEA 0183 (v1.
EXAMPLES SYSTEMS USING NETWORK QUAD Only one Network QUAD unit should have speed and depth sensors connected to it and set to transducer mode. Up to three more Network QUAD (set to repeater mode) or QUAD REPEATER units can be connected on to the system network. QUAD Main unit QUAD Repeater Mode QUAD Repeater Mode QUAD Speed Sensor When in repeater mode, if the data is not being received from the system network, the display will show OFF when a key is pressed.
SELECTING THE DISPLAY MODE The Network QUAD unit has two operating modes. The correct mode must be selected for your Network system to operate properly. tYPEt Transducer mode, the unit uses and displays speed and depth data from sensors connected directly into the display unit. tYPEr Repeater mode, the unit operates as a repeater using data from the system network. Press TIMER key to display stored log. 610-HB-0503-05 Press SETUP key to display the current mode.
USING THE SPEED KEY Boat speed information is permanently displayed in the top area of the LCD. Press the SPEED key to cycle through the following options: SPEED Current boat speed in Knots, can also be displayed in MPH. AVERAGE Average boat speed since the last reset of the trip log. SPEED MAX SPEED Maximum boat speed since the last reset of the trip log.
CALIBRATION AND OPERATING PARAMETERS When current boat speed is displayed, press the SETUP key to cycle through the following options: DAMPING The response time of the display to changes in boat speed. SPEED KNOT The boat speed can be displayed in Knots or MPH. This setting also changes the log units to Nautical or Statute Miles. CAL Manual boat speed and log calibration. LOG CAL Manual boat speed and log calibration. AUTO CAL Automatic boat speed and log calibration.
SETTING THE DISPLAY DAMPING Damping allows the response time of the displayed speed value to be slowed down if it is to jumpy in rough weather, or to sped it up when the conditions are calm. The damping works by averaging the values over a set time period; the longer the time period the smoother the readings, however the longer it takes to see a change. Similarly the shorter it is the jumpier the readings, but the faster the response.
SETTING THE SPEED AND LOG UNITS The Network QUAD can be set to display boat speed in Knots or MPH. If boat speed is in Knots then log is in Nautical Miles. If boat speed is in MPH then log is in Statute Miles. Press SPEED key to display current boat speed. 610-HB-0503-05 Press SETUP key twice. The speed digits will blank. Press ENTER key if the units are to be changed. Use S or T to change the units. Press ENTER key to memorise the change. Press SPEED key to display current boat speed.
SPEED AND LOG CALIBRATION Before Network QUAD is used for navigation the boat speed and log have to be calibrated to ensure accuracy for your installation and the boats hull characteristics. Three methods are available with the Network QUAD unit, two manual adjustments and one automatic: MANUAL CALIBRATION 1. CAL The displayed boat speed value is corrected manually to read a known measured speed. 2. LOG CAL The units calibration figure (Hz/Knot) is manually adjusted to correct log and speed inaccuracy.
METHOD 1. - MANUAL CALIBRATION - CAL This procedure requires a reference boat speed with which to compare the Network QUAD units displayed boat speed. For example, another boat with an accurate calibrated log, or if the top speed of the boat is known this value can be entered during a sea trial to correct the displayed value. IMPORTANT NOTE: This method of calibration must not be carried out at boat speeds of LESS THAN 3 KNOTS as inaccurate values can be entered into the units memory.
METHOD 2. - MANUAL CALIBRATION - LOG CAL If the log or boat speed is in error by a known percentage then this method allows the calibration figure or LOG CAL to be adjusted by that amount. The calibration figure is measured in Hertz per knot (Hz/kt), the factory set value is 6.25. NOTE: The accuracy of this method is dependant upon the accuracy of the calculated percentage error. Using the factory set LOG CAL of 6.25 Hz/kt: • If the display is under reading by 10% subtract 0.
METHOD 3. - AUTOMATIC CALIBRATION - AUTO CAL This procedure will automatically and accurately calibrate the boat speed and log and is the recommended method for most boats. • Press the ENTER key when in line with marker A, to start run 1. The display will flash AUTO CAL 1. Press ENTER key again when in line with marker B, to freeze run 1. The display will flash, showing the distance so far for one run. • Turn the boat around for run 2 in the opposite direction over the same measured distance.
AUTOMATIC CALIBRATION PROCEDURE Distance measured on a chart Start Run 1 Stop Run 1 Stop Run 2 Start Run 2 Start Run 3 Stop Run 3 ABORTING AUTO CAL 610-HB-0503-05 14
RESETTING THE DEAD RECKONED DISTANCE This facility allows the Dead Reckoned (DR) distance log to be reset. The Network QUAD unit cannot display the DR information, however Network SPEED and Network DATA both display it. Press SPEED key to display the current boat speed. 610-HB-0503-05 Press SETUP key 6 times to display dr. The display will flash. Press ENTER key, there will be no change on the QUAD unit LCD but the dr log has been reset.
USING THE DEPTH KEY The current water depth is permanently displayed in the bottom LCD area in metres, feet or fathoms. The unit is factory set to metres. The depth displayed is from the depth datum, see DEPTH DATUM. Press the DEPTH key to cycle through the following options: CAL The Depth Datum can be adjusted so the displayed water depth is from the waterline, the depth sensor (transducer) or the keel or outdrive depth. The unit is factory set to display water depth from the transducer.
THE DEPTH DATUM - CAL The depth datum CAL is an offset calibration value used to determine the displayed information reference point. It is added to the actual measured water depth to display the depth from the waterline, the depth sensor (transducer) or the keel/outdrive depth. The Network QUAD unit has factory set CAL of zero, i.e. the depth is displayed from the transducer. The CAL value is displayed in the same units as the depth.
SETTING THE DEPTH DATUM CAL zero, depth from transducer. CAL positive, depth from waterline. CAL negative, depth from keel. NOTE: If the CAL LOCK is set then the CAL value cannot be changed. Consult your B&G dealer for further advice. Press DEPTH key to display depth datum CAL. 610-HB-0503-05 Press SETUP key to display current datum value. The display will flash.
