About the application notes
General purpose
This document includes application notes for DEIF’s wind sensors type WSS 550 and WSS 750
in system solution with one or more XDi-N display-based wind indicators.
XDi-N is available in three sizes: XDi 96 N, XDi 144 N and XDi 192 N.
The DEIF XDi-N Wind version is delivered with a pre-installed indicator library with a selection of
standard wind indicators to choose from during installation.
The setup guidance in this application note refers to the DEIF standard wind indicator library:
Library owner: 000002 Library no. 001 for XDi 144 N and XDi 192 N.
A similar library is available for XDi 96 N with the same owner and library number.
In this document, you can find typical application examples for different types of vessels.
In the application examples, the DEIF standard heated wind sensor WSS 550 is used.
For demanding applications, the WSS 550 can be directly replaced by the DEIF high performance
WSS 750 sensor.
It is also possible to use another manufacturer’s wind sensor providing a standard NMEA wind
data output.
The general purpose of the application notes is to provide the necessary design information about
typical wind measuring systems.
Intended users
The document is mainly intended for the person responsible for the technical designing of wind
indicator systems for ships. In most cases, this would be a system integrator or bridge panel
designer. Naturally, other users might also find useful information in this document.
It is important to read the user and installation documentation in addition to the information you get
in this application note.
Contents/overall structure
The document is divided into chapters and in order to make the structure of the document simple
and easy to use, each chapter will begin from the top of a new page.

Product installation details
XDi-N connections
In the following, the term XDi-N represents any of the three sizes: XDi 96 N, XDi 144 N or XDi
192 N.
To present wind data from a wind sensor, an NX2 NMEA I/O extension module must be mounted
to the rear of the XDi housing. The 3 NMEA inputs on the NX2 module enable the XDi-N to receive
NMEA data from a wind sensor, true wind data from another system or speed and heading data
to enable internal calculation of true wind data.
When the XDi-N is used as a second or third wind indicator in a system, it can receive wind data
directly from the CAN bus using the XDi-net protocol. In this case, no NX2 NMEA extension
module is required.
Which type of input data to be used depends much on the application as you will see in the
different application examples later in this document.
To make the installation setup of the XDi-N, please see appendix 1 where you will find a detailed
description of how to select the right setup for dimmer, selection of virtual indicator and input
setup. The XDi-N setup wizard will guide you through these selections.

Wind system accessories
Different length of extension cable for the sensor and a connection box is available as
accessories.
When using extension cable, it is important to read the installation guidelines in the wind sensor
documentation.
Other manufacturer’s wind sensors
The DEIF wind sensors shown in all the system applications in this document may be replaced
with a similar wind sensor from another manufacturer. The sensor must have either RS-422 or
RS-485 output, and it must output relative wind data sent in the NMEA 0183 MWV sentence. The
wind speed can be either m/s or knots.
If the sensor has an RS-422 output, it is recommended to connect it to one of the standard NMEA
inputs (input RX1 or RX3) on the NX2 module. If the interface is RS-485, use the same input as
the DEIF sensor (RX/TX2, RS-485).

System 3 - Relative and true wind indication
In this application, the XDi-N indicator is able to present both the relative (apparent) wind speed
and direction and in addition, the true wind speed and direction relative to the bow of the ship
(see Appendix 6 for definitions of true wind).
The XDi-N wind indicator receives the relative wind data via the RS-485 NMEA input from any of
the DEIF wind sensors, either the WSS 550 or WSS 750.
XDi-N can calculate the true wind data if the ship’s speed data is available from the speed log or
navigation system. Both speed over ground and speed through water can be used for the
calculation.
XDi-N can receive speed data if an NMEA output providing the speed data is connected to one
of the two standard NMEA inputs on the NX2 module (RX1 or RX3). The following NMEA
sentences may contain the ship’s speed and can be used as input to the true wind calculation:

Instead of calculating true and geographic true wind, the XDi-N can also receive those
System 4 - relative, true and geographic true wind indication
In this application, the three XDi screens from system 3 are extended with one screen more
presenting geographic true wind (see Appendix 6 for definitions of true wind).
The XDi-N wind indicator receives the relative wind data via the RS-485 NMEA input from any of
the DEIF wind sensors, either the WSS 550 or WSS 750.
The XDi-N can calculate the true wind data if the ship’s speed and heading data is available from
the speed log, heading compass or navigation system. Both speed over ground and speed
through water can be used for the calculation.
To be able to calculate true wind, the XDi-N must receive speed and heading data from the ship’s
systems connected to the standard NMEA inputs on the NX2 module (RX1 and/or RX3).
The following NMEA sentences contain the ship’s speed and heading information used as input
to the true and geographic true wind calculation.
Speed: VHW, VBW, VTG, RMC
Heading: HMR, THS, HTD, VHW, HDT, HDG
Magnetic variation: HMR, RMC, HDG (this parameter is used to calculate between magnetic and
true heading)
data directly from another system connected to one of the NMEA inputs. The NMEA
sentence must be MWD (geographic) and MWV (true).

Installation and setting
Using the DEIF standard wind library 001, different wind indicators can be selected during setup.
The library contains a design suitable for installation on a normal forward-looking bridge (forward)
and a design for mounting on an aft bridge.
A standard indicator for this application can be VI005 wind relative and true FWD. This indicator
has 4 screens that can be toggled between using the left push-button on the front of the XDi-N.
(Toggle between the screens is also possible from an external push-button).
Use the left button on the front to toggle between the four screens showing: relative wind, true
wind, geographic true wind and a combination of relative and true wind.

Dimming
Standard dimming of the XDi-N is done via the two centre buttons on the front of the XDi-N unit.
Alternatively, the XDi-N can be set up for external dimming control from either push-buttons or
potentiometer, please see Appendix 4 for details.
Installation wizard
When the XDi-N has not yet been set up, it will automatically start the start-up wizard.
Settings to be selected in the start-up wizard to show a wind system presenting relative, true and
geographical wind for a forward bridge with dimming controlled using front buttons is seen in the
tables below.
Select a CAN NodeID.
In this system, CAN/XDi-net is not used, so just press OK to select the default CAN NodeID = 40.
