  • Page 9: Chapter 1: Introduction To The Wtp2

    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.

  • Page 10: Typical Setup

    Chapter 1 Introduction to the WTP2 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.

    FFDs correctly. Page Key Operation of this single key enables the user to quickly access eight functions of the WTP2 System, by selecting any one of the four pre-set page displays (2 functions per page) with a simple key press.
  • Page 12 Chapter 2 Basic Operation Notes • If you are ‘lost’ in the system, press the Page Key to immediately return to the top-level display. • The initial four pages can be reconfigured using the remaining keys and the menu system (see Page Display Configuration below).

  • Page 13: Examples Of Operation

    Our second example is configuring the NAV key. The NAV key allows the user to select either Rhumb Line or Great Circle navigation information to be displayed; by default the FFDs show Rhumb Line pages. WTP2 only uses Great Circle waypoint data so we need to modify this page. To select the Great Circle mode, proceed as follows: Press the Page Key once.

  • Page 14: Input Selection Via Deckman

    Multiple Compass, Boat Speed and GPS Inputs WTP2 is able to handle up to three compass inputs (as well as associated heel and trim values), two boat speed inputs and two GPS inputs. This is useful for testing purposes, to compare different sensors, or as a backup.

  • Page 16 The raw data from the standard port and starboard paddle inputs (63 and 64 respectively) are combined to make Boatspeed, the WTP2 uses Heel Angle to determine which of the two inputs to use. The raw data from the second speed sensor is used to make Boatspeed2 (Note that this stage is necessary in order to filter the raw data from the sensors).

  • Page 17: Deckman Control Facilities

    Deckman Control Facilities To access the WTP2 control facilities in Deckman, choose gmenu → instrument control. You will then see a dialog on the screen. Each box along the top of the dialog accesses a different control facility, as described below.
  • Page 18 Chapter 2 Basic Operation Calibration Controls the calibration of variables by allowing you to input a calibration value to a particular variable: Bspd_port and Bspd_stbd are boat speed calibrations for the port and starboard side respectively in Hertz/knot. If you have only one boat speed sensor enter the same value in both port and starboard.
  • Page 19 Chapter 2 Basic Operation Settings The settings dialogue controls all the normal items required to setup the WTP2. mast_height is used for wind calculations involving the rate gyros. This should be set to the distance from the waterline to the masthead sensor in feet.

    Deckman and displays (/data/ directory). Note that if you modify files with WTP Guru you will need to re-boot the WTP2 before they take effect – as such it is often just as easy to use the FTP access to the files for this purpose which allows the backup of the existing files before making changes.

    At this stage it is likely that an error dialogue will appear advising that it is not possible to connect anonymously to the WTP2, at this stage it is necessary to clear the dialogue box and select the ‘Login As…’ option from the file menu.

  • Page 25: Chapter 4: Data Files

    ‘Deckman Control Facilities’, see page 2.7. The configuration of the WTP2 can be changed to suit individual requirements by using the data files. The data files described below control how data is input onto the WTP2, stored in the variable database and output to Deckman and the displays.

  • Page 26: Defining The Variables

    Defining the variables bg_vars.d This file is the most important on the WTP2, as it lists all of the variables in the system - if variables are not listed here then they will not be in the WTP2 at all.

    This file controls the configuration of the standard function menus onto the FFD displays – the menu items which are standard parts of the WTP2 system but are not declared normally by the FFD are declared here.

Defining Custom Fastnet Menus usermenu.d This file enables you to either add a function to an existing menu or add a new menu with associated functions. In the file example shown below we have added two new menus called DECKMAN and SAILS with functions and we have also added two functions to the existing PARAMTR menu.

  • Page 40 Chapter 4 Data Files ============================================ Each line defines a single variable that is output to Deckman; the operation of this file varies slightly depending on whether the communication with Deckman is serial or Ethernet. For Serial communications the entire contents of the file, including duplicate items, are sent once per second - so in the example above there are some variables (55, 18, 17, 91, 2) which are repeated five times, these variables are therefore sent five times per second (5Hz), 5Hz is the maximum rate used on the serial output.

  • Page 47 The addition of this file allows the WTP2 to accept serial inputs from loadcell systems which are generally used for large numbers of loadcells. If a small number of loadcells are installed it is normal to use an analogue device and to connect to analogue inputs on the WTP2.

  • Page 48: Example On Using The Data Files

    This would give out a voltage that would need to be fed onto the analogue. Note: If your system requires additional inputs, the WTP2 can be supplied with an analogue expansion card. In this example we will add a variable called ‘mastfoot’ which we will input to analogue channel 8.

  • Page 50 Chapter 4 Data Files Example The new variable we are adding here is a Moving Average for the True Wind Direction, we will call the variable MA_TWD. In bg_vars.d we add a line to define the new variable, in this case the next available variable number is 110, so we add the following line setting variable 110 to be MA_TWD, has zero decimal places and is 0-360 data.

  • Page 51: Chapter 5: Parameters

    Each variable requiring calibration has its own calibration file (.cal file extension), all calibration files are located in the Calibs directory. Various calibration functions are available to the WTP2 but most of them are variations on linear as in the diagram. The first parameter describes the type of calibration:...
  • Page 52 Here, the offset to the compass heading is altered by the heel angle. Of course, the corrections in the previous table will continue to be applied before the corrections with respect to heel. Here you can see that, as well as interpolating within the calibration points you enter, the WTP2 will also extrapolate outside them.
  • Page 53 3.3. Calibration example 5 By way of an example we will attempt to recreate the leeway calculation that WTP2 does as standard. The standard calculation is based on the formula:...

  • Page 54: Sensor Calibration

    Identifiers recognised are table, constant and variable. Number ‘–1’ indicates that the calibrations are applied directly to the variable. Any other number indicates that the calibration is with respect to a different variable in the WTP2 database, with the number being the variable number from bg_vars.d.
  • Page 55 The B&G systems use W = (1/A)H + B where A is calibration in Hz/kt, H is the anemometer frequency and B is an offset. So for the standard of A=1.04 and B=1.04 the equivalent WTP2 calibration is (0, 1.04) and (10.4, 11.04).

  • Page 57 >9 Wind To fully understand the filtering of the wind functions it is necessary to consider the order in which WTP2 calculates the various functions and where filtering is applied. When the wind is measured it is initially corrected for masthead unit offset and mast rotation (or twist), then the rate-gyro corrections for pitching and rolling are applied and then the triangulation with Boat Speed is done and Course added to get the Original Wind speed and Wind Direction.

  • Page 61: Chapter 6: Installation

    The engine box is NOT a good place to install your instrument system processors; it is hot and electrically noisy. The WTP2 unit is fixed to the mounting surface via 4 mounting lugs, it is recommended that the unit is located on a batten to reduce shock loading on the mounting lugs in extreme conditions.
