Welcome to the B&G Network system. This world beating series of intelligent
navigational instruments has been brought to you through a combination of
scientific innovation and high quality production to create a computerised data
system you can trust. As an intelligent system each unit can be used by itself to
display specific data, alternatively any combination of units can be linked into a
Network with units processing their own data or acting as repeaters for data
from other units. This Network providing a comprehensive navigational system.
Screened cables combined with the latest technology provide protection from
interference between units and other systems.
The Network system is continuously expanding your options and currently
consists of the following units:

Network DEPTH
Network QUAD
Network WIND
Network TACK

GENERAL INTRODUCTION TO B&G NETWORK

3
The Network COMPASS unit uses the latest advances in electronics to display
Off Course, Cross Track Error (XTE)*, Rudder* and Head/Lift information on an
easy to read Liquid Crystal Display (LCD). Five keys on the unit select the
displayed data, calibration factors and alarms.
It can operate as a standalone unit compass display or as part of an Integrated
B&G Network Instrument System. The unit can also operate as a repeater of
course data received via the Network. These connections plug directly into the
rear of the display.
The Network COMPASS includes two adjustable alarms:
•Off course alarm
•Head alarm
An internal alarm buzzer will sound and the display will flash when the alarm
condition is met. Other Network instruments will also sound their alarms and
flash their displays.
Additionally a racing timer with alarm signals at set intervals is included in the
unit.
* These functions will only appear if the relevant sensors i.e. GPS or PILOT are
in the system
INTRODUCTION TO NETWORK COMPASS

Up to four COMPASS units can be connected to the system. Only one of these
should be linked to a fluxgate and set to transducer mode, the other three must
be set to repeater mode. Refer to SELECTING THE DISPLAY MODE for
details. The MODE key then cycles the display through Off Course, Cross
Track Error (XTE), Rudder and Head/Lift displays (if enabled).

Pressing the MODE key will cycle the display between Off Course, Cross Track
Error (XTE) if GPS is fitted, Rudder angle if Network PILOT fitted and the
Head/Lift display (if enabled).

The unit will autodetect the presence of a GPS or PILOT on the Network and
will activate the displays accordingly. The Off Course display is used to show
the difference between the current heading and the heading stored in the
selected course memory (see SETTING THE COURSE MEMORIES).
In this instance the vessel is heading starboard of the setting in course 2
memory, the display shows the current bearing. The Off Course scale is visible
below the bar graph which points to port, the legends STEER and PORT
indicate the direction required to steer to correct the error.
The Off Course scale indicates how many degrees the vessel is from its
intended heading.

Whilst in Off Course mode the two course memories may be set. The currently
active course memory is shown by the legend CRSE1 or CRSE2.
Pressing the LOCK key brings up the current course memory (e.g. CRSE1)
which will flash on the display. Pressing LOCK again displays the second
course memory (CRSE2). Whilst the setting is displayed it can be adjusted by
using the ▲and ▼keys (normally the MODE and TIMER keys). The display
will revert to normal four seconds after the last key is pressed.
Alternatively the displayed course memory can be reset by sailing on a heading
then depressing the LOCK key for one second. The current course will then be
stored in the selected course memory.
If a remote button, shown below, is fitted as an option then this performs the
same functions as the LOCK key.

REQUIRES A GPS ON THE NETWORK. The Cross Track Error display is
used to indicate how far the vessel is from the intended track (from waypoint to
waypoint).
In this instance the vessel is heading starboard of the planned course. The
display shows the current bearing and the XTE scale is visible above the bar
graph which points to port, the legends STEER and PORT indicate the direction
required to steer to correct the error.
The XTE scale indicates how many nautical miles the vessel is from the track
(waypoint to waypoint).

REQUIRES B&G NETWORK PILOT IN CIRCUIT. The rudder display indicates
the current angle of the rudder, which is particularly useful on wheel steered
boats.
The vessel is turning to starboard, the display shows the current heading and
the rudder scale is visible beneath the bar graph which points to port; the
direction to turn the wheel to straighten the rudder.
The scale indicates the degrees at which the rudder is angled.
