DIGITAL YACHT

1. Introduction

Congratulations on the purchase of your WND100 Wind Transducer. It is recommended that this product is installed by a professional, marine electronics engineer.

Installation of the Wind Transducer should only be conducted when the mast is down.

2. Before you start

You will need the following items and tools to complete the installation:

• The WND100 Transducer with 20m Cable (supplied)
• A 1A inline fuse
• 3x Suitable M5 Nut and Bolts or No10 Self Tapping Screws to fix the transducer to the top of the mast
• A suitable waterproof deck gland for the cable to pass through

To display the wind data, you will need a suitably compatible device with an NMEA0183 data input at 4800 baud.

3. Installation

The WND100 Wind Transducer should be mounted so as to position its sensing parts, the cups and the vane, that they are always directly in the wind whatever direction it is coming from. In a boat the best place is high and forward of the mast. In fixed installations, the unit should be clear of a roof or similar obstructions, by at least half a meter.

It is very important that the WND100 is mounted parallel to the centre line of the boat. It is possible to calibrate the WND100 to remove any angular offset that might be introduced during installation, but if you can accurately position the transducer with the main shaft facing forward, parallel to the boat's centre line, then this will ensure best performance and accuracy.

Using the cable base as a template, spot mark through the fixing holes to the mast cap. The cable should run aft, with the single screw forward. Use stainless steel screws to fix the cap, (either No10 self-tapping screws, or M5 machine screws).

The WND100 can then be fitted to the base with the two screws provided. The 20m cable of the WND100 is terminated with bare ended wires.

Dimensions

4. Electrical Wiring

The WND100 is designed to work from a DC supply with a voltage range of 8V to 30V and typically consumes about 15mA (0.015A). To protect the wiring, it is recommended that an inline fuse of 1A is fitted to the Red (Power+) wire of the WND100 cable. This is not necessary when connecting it to the WindSense wireless interface, which has internal self-resetting fuses for the WND100.

Primarily the WND100 is designed to be used with Digital Yacht's wireless WindSense product, but it can also be used in various applications, such as replacing an existing wind transducer, providing a Wind Input to a Multi-Function Display (MFD), or getting Wind data onto a Personal Computer.

The WND100 uses an industry standard NMEA0183 interface to communicate wind data. The NMEA0183 signals are not true differential inputs and outputs. When connecting to an NMEA0183 device with a differential input, the device's negative Input should be connected to the Shield wire of the WND100.

NMEA0183 Wiring Diagram

Wiring diagram for NMEA0183 connection. It shows the 'Boat's DC Supply' (+12v, -0v) with a recommended 1A inline fuse on the RED wire of the 'WND100 Cable'. The cable includes RED (Power+), BLUE (WND100 NMEA Input+ [Not Connected]), YELLOW (WND100 NMEA Output+), and GREEN (Common Ground). These connect to the 'Equipment's NMEA0183 Input' (+ and -). A note specifies that if equipment has only one input, connect the WND100 Yellow wire to the equipment's Input+.

PC COM Port Wiring Diagram

The WND100's Blue (NMEA IN -), Yellow (NMEA IN +), and Shield (NMEA OUT) wires connect to specific pins on a 'COM PORT D CONNECTOR' (Pin 5 for GND, Pin 3 for NMEA IN +, Pin 2 for NMEA OUT).

USB to NMEA Converter Wiring Diagram

It shows the 'Boat's DC Supply' (+12v, -0v) with a recommended 1A inline fuse on the RED wire of the 'WND100 Cable'. The WND100 cable (RED, BLUE, YELLOW, GREEN) connects to the 'USB Connection to PC' via ORANGE (to BLUE), YELLOW (to YELLOW), and BLACK (to GREEN) wires.

Once wired, apply power. Ensure the equipment is set to receive NMEA0183 Wind Data at 4800 baud and verify valid Wind data is being received.
