GENERAL INTRODUCTION TO B&G NETWORK The B&G Network range of instruments are 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 DEPTH NETWORK DEPTH DISPLAY UNIT The Network DEPTH unit measures and displays Depth information on a large Liquid Crystal Display (LCD). The five keys allow selection of the displayed information and setting of the units mode, calibration factors and alarms. It can operate as the main Network DEPTH unit either alone or as part of an Integrated Network Instrument System taking inputs directly from a Depth Sensor that plugs directly into the rear of the display.
EXAMPLE SYSTEMS USING NETWORK DEPTH Only one Network DEPTH unit should have a depth sensor connected to it and set to transducer mode. Up to three more Network DEPTH units can be connected on to the system network, these must be set to repeater mode. See SELECTING THE DISPLAY MODE. 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. rEP Repeater mode, the unit operates as a depth repeater using data from the system network.
SELECTING THE DISPLAY MODE The Network DEPTH unit has two operating modes. The correct mode must be selected for your network system to operate properly. trA Transducer mode, the unit uses and displays depth data from a depth sensor connected directly into the display unit. rEP Repeater mode, the unit operates as a depth repeater using data from the system network. Press SIGNAL key. 610-HB-0501-04 Press SETUP key to display the current mode. Press ENTER key if the mode needs to be changed.
USING THE DEPTH KEY Press the DEPTH key to cycle through the following options: • DEPTH M The current water depth in metres M, can also be displayed in feet FT or fathoms FA. The unit is factory set to metres. The depth displayed is from the depth datum, see below. • D CAL M The Depth Datum can be adjusted so the displayed water depth is from the water- line, the depth sensor (transducer) or the keel/outdrive depth. The unit is factory set to display water depth from the transducer.
SETTING THE DEPTH UNITS The Network DEPTH unit can be set to display depth in Metres M, Feet FT or Fathoms FA. The selected units are used for displayed depth information on all Network instruments on the entire network system. Press DEPTH key to display the current depth. 610-HB-0501-04 Press SETUP key. The depth display will go 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 DEPTH to display current depth.
THE DEPTH DATUM - D CAL The depth datum D 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 DEPTH unit has factory set D CAL of zero, i.e. the depth is displayed from the transducer. The D CAL value is displayed in the same units as the depth.
SETTING THE DEPTH DATUM D CAL zero, depth from transducer CAL TRA. D CAL positive, depth from waterline CAL W/L. D CAL negative, depth from keel CAL KEEL. NOTE: If the CAL LOCK is set then the D CAL value cannot be changed. Press DEPTH key to display depth datum D CAL M. 610-HB-0501-04 Press SETUP key to display current datum value. Press ENTER to adjust the datum value. Use S or T to adjust the value. Press ENTER to memorise the new value. Press DEPTH to display the depth datum.
USING THE SIGNAL KEY Press the SIGNAL key to display a letter of merit from A to F, this is an indication of the return echo strength. A is excellent, F is poor. The sea bed can have an effect on the quality of the return echo strength, i.e. very good echoes are returned from rock, shale and sand, however poor echoes are returned from mud. Therefore the merit letter could be A or B for rocks but C or D for mud.
USING THE ALARM KEY Press the ALARM key to cycle through the following options: SHA A M DEP A M ANC A M Shallow Alarm, when enabled it will sound if the water depth is less than the alarm value. Deep Alarm, when enabled it will sound if the water depth is more than the alarm value. Anchor Alarm, when enabled it will sound if the water depth is outside two alarm limits. DEPTH ALARMS The display will show OFF if the alarm is disabled or the alarm value when enabled.
ENABLING/DISABLING THE SHALLOW ALARM Press ALARM key to display shallow alarm SHA A M. Press SETUP key, the alarm state will be displayed. Press ENTER key, the display will flash. Use S or T to enable/disable the alarm. Press ENTER to memorise the change. Press ALARM key, the value is displayed. Use S or T to adjust the value. Press ENTER key to memorise the new value. Press ALARM key, the alarm is displayed. ADJUSTING THE SHALLOW ALARM VALUE Press ALARM key to display shallow alarm SHA A M.
ENABLING/DISABLING THE DEEP ALARM Press ALARM key to display deep alarm DEP A M. Press SETUP key, the alarm state will be displayed. Press ENTER key, the display will flash. Use S or T to enable/disable the alarm. Press ENTER to memorise the change. Press ALARM key, the value is displayed. Use S or T to adjust the value. Press ENTER key to memorise the new value. Press ALARM key, the alarm is displayed.
USING THE ANCHOR ALARM The Anchor Alarm uses two adjustable alarm limits. The alarm will sound if the water is deeper or shallower, by the amount set, than the original depth when the alarm was enabled. This allows you to adjust your anchor chain according to the rise and fall of the tides. The Network DEPTH unit has a factory set low limit of 0.5m and a high limit of 1.0m. The anchor alarm depth limits are shown alternatively when they are enabled and displayed using the ALARM key.
ENABLING/DISABLING THE ANCHOR ALARM Press ALARM key to display anchor alarm ANC A M 610-HB-0501-04 Press SETUP key, the alarm state will be displayed. Press ENTER key, the display will flash. Use S or T to enable/disable the alarm. Press ENTER to memorise the change. Press ALARM key, to display the anchor alarm.
ADJUSTING THE ANCHOR ALARM LOW LIMIT Press ALARM key to display anchor alarm ANC A M. Press SETUP key twice to display ANCH LOW value. Press ENTER key, the display will flash. Use S or T to adjust the displayed value. Press ENTER to memorise the new value. Press ALARM key to display the anchor alarm. Use S or T to adjust the displayed value. Press ENTER key to memorise the new value. Press ALARM key to display the anchor alarm.
USING THE LIGHTS KEY The Network DEPTH Display unit has 3 levels of illumination and off, controlled by the LIGHTS key. It also changes the illumination level of the key legends. The LIGHTS key is always illuminated so even in complete darkness the key can be located.
SETTING THE DISPLAY LANGUAGE The Network DEPTH unit can show LCD text in English or French. To change the display language procede as follows. Press SIGNAL key. 610-HB-0501-04 Press SETUP key twice to display the language setting. Press ENTER key if the language needs to be changed. Use S or T to change the language. Press ENTER to memorise the new setting. Press SIGNAL key to complete the change. The LCD now shows French text.
NETWORK ALARMS The Network DEPTH unit has an internal buzzer that willsound when an alarm condition is met on a Network unitthat has alarm functions ie. Network DEPTH and NetworkQUAD for depth alarms and Network PILOT for WatchAlarm and Off Course alarms. The unit will also displaywhich alarm is activated. NETWORK PILOT ALARM DISPLAYS The Watch Alarm is a count-down timer with is activated at the end of the preset count-down period. The display alternates between the messages below.
FAULT AND ERROR MESSAGES NETWORK PILOT FAULT DISPLAY UNIT INTERNAL ERRORS If Network PILOT should have a fault the autopilot computer unit will send a message to all other Network Display Units. The Network DEPTH unit will alternately display the follow message, the actual fault will have to read from the Network PILOT Display unit. In the unlikely event that your Network DEPTH unit should develop an internal error, the unit will sound it's alarm continuously and the display will show an error number.
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.
