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.

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 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. It will also
operate as a repeater of depth information received via
the two Network cable tails.

The Network Depth 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). The Network
DEPTH unit will also indicated Network PILOT alarms and
fault conditions.

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.

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.

The Network DEPTH unit can measure and display water
depth in the following ranges:

•

0.7 to 180 metres

•

2'4" to 590'

•

0.37 to 98.4 fathoms

•

Accuracy ± 2% or ± 0.2m (± 8")

If the Network DEPTH unit losses valid depth data, due
either the actual depth being outside the working range,
or to extreme turbulence in the water the LCD will show 3
"floating" bars. This shows that the unit is attempting to
calculate the depth and is still functioning.

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.
