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:

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).

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.

THE HEAD/LIFT PAGE HAS TO BE ENABLED IN THE SET UP MENU before
it can be displayed.
The port and starboard tacks are stored manually as PORT and STBD
headings (see SETTING THE COURSE MEMORIES). When the helmsman
has to vary from these headings due to wind changes the legends HEAD or
LIFT will appear on the display for the relevant tack. If wind data is available
over the Network a tack will automatically change between the PORT and
STBD reference course. Otherwise it can be switched manually by two short
presses of the LOCK key or the remote button. The HEAD/LIFT values are
displayed in the analogue bar graph as degrees. If the Off Course alarm is
enabled the unit will sound an alarm and HEAD will flash if a head occurs,
pressing ENTER on the unit will cancel the alarm. The alarm will not sound for
a lift.

Pressing the TIMER key enters the timer display mode, this is shown by the
presence of a colon which flashes every second.
The timer can be set to any required value to a maximum time period of 99
hours 59 minutes and 50 seconds. The analogue bar graph shows the time left,
in minutes, from 30 minutes before time zero (bar graph on the left) to 30
minutes after (bar graph on the right).
The unit will also beep to indicate the passage of set units of time, the number
and frequency of beeps depending on the time left to time zero, there are no
beeps after time zero. The beep sequences are shown in the table below.
Beeps begin at Beeps end at Number of beeps Frequency
< 60 hours 1 hour 5 every hour
< 1 hour =>10 minutes 4 every 10 minutes
< 10 minutes => 1 minute 3 every minute
< 1 minute => 10 seconds 2 every 10 seconds
< 10 seconds >0 1 every second
= 0 >-10 seconds continuous for 10 seconds
This means that for the example given above of 1 hour 48 minutes the following
beeps will occur:
•5 beeps at 1:00
•4 beeps at 0:50; 0:40; 0:30; 0:20; 0:10
•3 beeps at 0:09; 0:08; 0:07; 0:06...0:01
•2 beeps at 0:00:50; 0:00:40...0:00:10
•1 beep at 0:00:09; 0:00:08; 0:00:07...0:00:01
•continuous beep at 0:00:00 for ten seconds
At each of these periods the display will briefly show the time left.

REQUIRES A B&G NETWORK AUTOPILOT IN SYSTEM. If a B&G Network
autopilot is present in the system, and the unit is set up within a system that
includes a Network ACP1 or ACP2 then there are two options for the Network
configuration.
•The COMPASS unit can display rudder and compass information
generated by the PILOT.
•The fluxgate sensor can be connected to the COMPASS unit giving an
alternate remote fluxgate option.
The Network is more efficient if the fluxgate is connected to the Network ACP
Pilot and the COMPASS is used as a repeater for the data but the system will
operate normally with the pilot accepting data from the COMPASS unit.
Only one fluxgate is necessary for the Network but if a backup fluxgate is added
and fitted into the COMPASS unit then it will override the PILOT's internal
compass. The PILOT will then act as a repeater for the COMPASS data. It is
important that the COMPASS is specifically set up in repeater mode. The
fluxgate on the Network COMPASS may be enabled by changing modes in the
event of a PILOT/FLUXGATE failure.
PILOT Off Course data is not fed into the COMPASS unit through the Network.
If this information is required the PILOT heading can be manually entered into
one of the COMPASS course memories.

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.
All Network Instruments are designed for mounting on or below deck. A
mounting position should be selected where they are:
•Easy to read by the helmsman
•On a smooth and flat surface
•At least 100mm (4") from a compass
•Accessible from behind for fitting locking studs if required.
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.
•The template allows 4mm (5/32") between adjacent units for the suncover,
increase this distance if required to maximum of 60mm (2 3/8") between
units or 180mm (3 1/8") between centres. For greater distances between
units extension cables are available.
•
••
•Use a 70mm (2 3/4") diameter hole-cutter for the mounting bracket hole.
•
••
•Use a 2.9mm for the self-tapping screw holes. Use a 5mm (3/32") drill for
the locking stud holes.
•
••
•Secure the mounting bracket to the bulkhead with the self-tapping screws
supplied
•
••
•Fit the rubber sealing gasket around the mounting bracket.
