GENERAL INTRODUCTION TO B&G NETWORK

The B&G Network range of instruments is 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 TACK

The Network TACK unit is a analogue Magnified Wind Angle
repeater used for sailing on the wind or running, with a back­lit Liquid Crystal Display (LCD) that can show other wind
information selected by pressing one of the five keys. It has
no sensor interfaces as all data is passed to the unit via the
system network cables. Network TACK must be connected
to a system that contains a Network WIND unit for wind data
and a Network SPEED unit (for true wind and VMG
functions) via the two network cable tails at the rear of the
unit.

The unit is capable of transmitting NMEA 0183 v1.5 data via
the network cables.

The five keys give the following selections:

NETWORK TACK DISPLAY UNIT

• AWA Apparent Wind Angle

• TWS True Wind Speed

• TWA True Wind Angle

• VMG Velocity Made Good

• LIGHTS Three levels of illumination and off.

EXAMPLES SYSTEMS USING NETWORK TACK

Network QUAD, Network WIND and Network TACK units.
Speed data being supplied from the Network QUAD unit for
true wind and VMG functions.

Up to a maximum of four Network TACK units maybe used
in an integrated Network Instrument System, where the total
number of units does not exceed twenty.

Network SPEED, Network DEPTH, Network WIND and
Network TACK. Speed data being supplied from Network
SPEED unit for true wind and VMG functions.

The Network units can be connected together in any order
as data is shared via the system network cable link.
