GENERAL INTRODUCTION TO B&G NETWORK

The B&G Network range of instruments has been 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. All Network instruments can be linked to Network PILOT, Network CHART, Network GPS or Network LORAN receivers or via NMEA 0183 (v1.5) to other navigational equipment.

INTRODUCTION TO NETWORK SPEED NETWORK SPEED DISPLAY UNIT

The Network SPEED unit measures and displays Speed, Log, Timer and Sea Temperature information on a large back-lit Liquid Crystal Display (LCD). The five keys allow selection of the displayed information and setting of the units mode, calibration factors and operating parameters.

It can operate as the main Network SPEED unit either alone or as part of an Integrated Network Instrument System taking inputs directly from a Speed Sensor which plugs into the socket at the rear of the display, or as a repeater of speed information received via the two Network cable tails.

The Network SPEED unit has no alarm functions, however it has an internal alarm buzzer that will sound when an alarm condition is met on Network Depth, Network QUAD or Network PILOT unit or to indicate a fault condition.

The unit is able to transmit NMEA 0183 (v1.5) data via the system network cables to other Network units and connect to an NMEA device e.g. a position fixer, with a special NMEA output cable.

IMPORTANT NOTE

Your Network SPEED unit must be setup and calibrated correctly before it is used as part of a navigational system.

EXAMPLES SYSTEMS USING NETWORK SPEED

Only one Network SPEED unit should have a speed sensor connected to it and set to transducer mode. Up to three more Network SPEED 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.

SELECTING THE DISPLAY MODE

The Network SPEED unit has three operating modes. The correct mode must be selected for your Network system to operate properly.

trA Transducer mode, the unit uses and displays speed

data from a speed sensor connected directly into the display unit.

rEP Repeater mode, the unit operates as a speed repeater

using data from the system network.

d Demo mode, the unit runs an internal demonstration

program.

Press LOG key to display stored log.

Press SETUP key to display the current mode.

Press ENTER key if the mode needs to be changed.

Use ¿ or À to change mode.

Press ENTER to store the new mode in memory.

Press LOG to complete the change.

USING THE SPEED KEY

Press the SPEED key to cycle through the following options:

• SPEED KT Current boat speed in Knots KT, can also be displayed in MPH MH.

• MX SP KT Maximum boat speed since the last reset

of the trip log.

• AV SP KT Average 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:

When in SETUP mode:

• DAMPING The response time of the display to changes in boat speed.

• SPEED KT The boat speed can be displayed in Knots KT or MPH MH. This setting also changes

the log units to Nautical Miles or Statute Miles.

• SPD CAL Manual boat speed and log calibration

• LOG CAL Manual boat speed and log calibration

• AUTO CAL Automatic boat speed and log calibration

The procedures for using the SETUP options are on the following pages.

• The SPEED key becomes the UP key ¿

• The LOG key becomes the DOWN key À

• The LIGHTS key becomes the ENTER key.

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 speed 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.

The Network SPEED unit has a factory set value of 5, this can be adjusted in the range 1 to 64, each step is approximately one second.

Press SPEED key to display current boat speed.

Press SETUP key twice to display damping value.

Press ENTER key if the value is to be changed.

Use ¿ or À to change the value.

Press ENTER key to memorise the change.
