Product Liability and Safety Warnings
Brookes and Gatehouse Limited accept no responsibility for the use and/or operation of this equipment. It is the
user’s responsibility to ensure that under all circumstances the equipment is used for the purposes for which it has
been designed.
Warning: Calibration
The safe operation of this equipment is dependent on accurate and correct calibration. Incorrect
calibration of this equipment may lead to false and inaccurate navigational readings placing the
yacht into danger.
Warning: Navigation Hazard
The WTP2 system is an Electronic Navigation aid and is designed to assist in the navigation of
your yacht. It is not designed to totally replace conventional navigation procedures and
precautions and all necessary precautions should be taken to ensure that the yacht is not placed
into danger.
Caution: Electrical Supply
This equipment is designed for use with a power supply source of 12V dc. The application of
any other power supply may result in permanent damage to the equipment and invalidating the
warranty.
Caution: Cleaning
The use of alcohol or solvent-based cleaners will damage this equipment and any warranty in
force will be invalidated.
Caution: Display Installation
Displays installed into locations manufactured from conductive materials (e.g. Steel, Carbon
Fibre etc.) should be insulated from the structure to prevent damage to the casings as a result of
the effects of electrolysis.

Preface
This manual is in three parts:
Basic Operation
Chapter 1: is a brief introduction to the WTP2, outlining the way the unit works and some of the differences
with other instrument systems.
Chapter 2: contains information about the basic operation of the WTP2 in conjunction with the B&G Deckman
software.
Most users should be able to operate the WTP2 from Deckman using the information contained in this section.
Customisation
Chapter 3: outlines the way a PC can be used to upload or download files to or from the WTP2.
Chapter 4: contains information on the use of the data files; these allow you to control the input of variables
onto the system and the way these are sent back out to the displays.
Chapter 5: concerns the calibration, damping and settings options available.
These chapters are mainly aimed at more experienced users, who may wish to alter variable inputs and outputs.
Installation and Maintenance
Chapter 6: outlines the installation of a number of different components, and is therefore aimed primarily at
those involved with the initial installation of the system; general wiring information is also included
in this section.
This section is aimed mainly to assist with the installation or maintenance of the system.

Chapter 1: Introduction to the WTP2
System Description
The B&G Wave Technology Processor in combination with the B&G Deckman software and range of H2000
displays make for the highest-level yacht racing instrument system in the world today.
Central to this high performance is the WTP2, a powerful processor running a Windows CE™ operating system and
a high speed analogue to digital board; such that calculations run some hundreds of times faster than on standard
instrument systems. This provides several benefits:
• All of the sensors can be sampled at higher data rates (100 times per second on analogue inputs)
• Wind calculations are improved by the addition of rate-gyro sensors to measure boat motion
• Compass inputs are enhanced using the same sensors
• Ethernet communications are used to allow high-speed communication with one or more PCs running the
Deckman tactical software
• The ability for users to create their own variables based on existing data
• Boat performance polars have a simple description and interpolation using cubic splines
• Additional terms are included to improve filtering and calibration (see Chapter 5:)
• Data is written to the display network at high rates (up to 10Hz)
• Users can configure the way information is displayed in menus with intelligent data switching.
Sensors
The WTP2 is designed to accept numerous different sensor types to allow the system designer to use the most
appropriate device in each application. All of the standard B&G H2000 sensors are compatible except that the
WTP2 uses an active NMEA sensor for Depth rather than the passive sensors normally used on H2000.
In addition to the normal sensors the WTP2 system also includes a 3-Axis Rate-Gyro sensor unit for measuring the
pitch, roll and yaw motion of the boat. It is this sensor that gives the WTP2 its name because it allows the removal
of the wave inertia components from the wind measured at the masthead.
If you have any sensor compatibility requirements that the standard WTP2 does not support please contact the B&G
Custom Projects team.

Typical Setup
The WTP2 is supplied with a straight through Ethernet patch cable that allows the WTP2 to be connected to an
onboard PC network via a hub or router.
