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.
4
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.
6
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.
Press SPEED key
to display current
boat speed.
