GENERAL INTRODUCTION TO B&G NETWORK
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 provides 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 COMPASS USER MANUAL
INTRODUCTION TO NETWORK COMPASS
The Network COMPASS unit uses the latest advances in electronics and magnetic
fluxgate technology to display a true or magnetic heading, as well as Off Course, Cross
Track Error (XTE)*, Rudder Angle* 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 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 -A- when the alarm
condition is met. Other Network instruments will also sound their alarms and flash their
displays, and the alarm condition can be cleared by pressing any key on any Network
instrument.
Additionally a racing timer with alarm signals at set intervals is included in the unit.
* These functions will only appear if the relevant sensors (for example, GPS
Network PILOT) are in the system.

EXAMPLE SYSTEMS USING 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 others must be set to repeater mode.
Refer to SELECTING THE DISPLAY MODE to see how to change modes.
In this configuration the main unit controls all the measurement parameters such as
offset and damping. These parameters can be changed via the keyboard on any of the
units: repeaters will send appropriate network messages to the main unit so that it can
keep its parameters up to date.

Page 5
NETWORK COMPA SS USER MANUAL
In this configuration the COMPASS unit is set to transducer mode and will send heading
data to the other instruments. The other Network units are also transmitting data that the
COMPASS may be able to use. For example, if the COMPASS is set to Head/Lift mode
the wind angle data will cause it to switch between port and starboard tacks
automatically.
INITIAL POWER-UP
When a COMPASS unit is powered up for the first time it will automatically adjust itself to
the phase characteristics of the fluxgate sensor, so if it is to be used with a fluxgate (that
is, in transducer mode) the fluxgate should be installed and connected before applying
power. Refer to the installation guidelines at the back of this manual for advice on
optimum siting of the fluxgate. During the phase adjustment the display will show PHS
and a pair of chevrons to indicate which of the phase settings is currently being tested.
When all the phase settings have been tested the optimum one is selected and stored for
future use. The complete phase adjustment procedure takes about 20 seconds.
The same phase adjustment is also carried out immediately before a calibration swing
(see CALIBRATING THE COMPASS, page 17).

CALIBRATING THE COMPASS
Remember that a compass offset may be entered if the heading shows a fixed error (see
section SETTING THE COMPASS OFFSET). The purpose of a calibration swing as
described in this section is to measure the deviation pattern of the compass at a large
number of points so that a more detailed correction can be made.
1. Press SETUP until the rotating segment is displayed.
2. Press ENTER to begin a calibration swing. This starts with a re-phasing of the fluxgate
signals which takes about 20 seconds (see INITIAL POWER-UP). The display shows
PHS and a pair of chevrons which move as successive phases are tested. When the
re-phasing has been completed the display shows a degree count, starting at zero.
3. Sail the vessel through a full circle. The display will count up to 360. During the turn
the bar graph shows the rate of turn in relation to the optimum rate of 4.5° per second:
chevrons on the left mean the turn rate is slower, chevrons on the right mean it is
faster. Slow turn rates are not a problem, but an excessively fast turn rate (say, greater
than 9° per second) may result in a failed calibration.

• The COMPASS unit can display rudder and compass information generated by the

PILOT
The Network is more efficient if the fluxgate is connected to the Network ACP Pilot and
the COMPASS is used as a data repeater. However, the system will operate normally
with the Pilot accepting data from the COMPASS unit.
Only one fluxgate is required per Network system. If a backup fluxgate is connected to
the COMPASS, it will override the PILOT's fluxgate if the COMPASS unit is set to
transducer mode. The PILOT will then act as a repeater for the COMPASS data. When
the backup fluxgate is not in use 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.

INSTALLATION
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.
SITING THE DISPLAY UNIT
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
MOUNTING THE DISPLAY UNIT
Use the cutting template supplied to mark the centres of the holes for the self-tapping
screws, 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 drill 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.
• Screw the locking studs into the back of the display head (if required).
• Carefully pass the cable tails through the mounting bracket hole and connect the
cables to the main units.
• Clip the display head into the mounting bracket.
• Secure the instrument with the thumb nuts supplied.

SITING THE FLUXGATE
Mount the unit upright on a flat vertical bulkhead where it will be:
• A safe distance from external magnetic interference: 1m/3ft from VHF, RDF,
loudspeakers, depth sounders, engines, or power cables carrying heavy current
• 3m/10ft from Radar and SSB equipment
• Externally mounted on steel hulled vessels
• Well protected from physical damage
• With the connector downwards
MOUNTING THE FLUXGATE
• Secure the unit in the selected site using the self tapping screws provided
• Route the cable to the Network COMPASS display unit avoiding other cables
carrying heavy currents (for example, engine starter or trim tabs)
• Secure in place using cable clips or tie-wraps
• Avoid bending the cable through a tight radius especially near the connector as
this may damage the wires inside the cable
