1 Introduction
Congratulations on your purchase of the Maretron WSO100 Ultrasonic Wind / Weather Station.
Maretron has designed and built your WSO100 to the highest standards for years of reliable,
dependable, and accurate service.
The Maretron WSO100 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless
installed and maintained in the correct manner. Please read carefully and follow these
instructions for installation and usage of the Maretron WSO100 in order to ensure optimal
performance.
1.1 Firmware Revision
This manual corresponds to WSO100 firmware revision 1.0.x .
1.2 WSO100 Features
The Maretron WSO100 has the following features.
• NMEA 2000® Interface
• Ultrasonic Wind Sensor
• Relative Humidity Sensor
• Barometric Pressure Sensor
• Temperature Sensor
• Waterproof Enclosure and Cable System
2 Installation
2.1 Unpacking the Box
When unpacking the box containing the Maretron WSO100, you should find the following
items:
1 - WSO100 Ultrasonic Wind/Weather Station
1 - Pole Mount Base
3 - Mounting Screws and Lock Washers
1 - WSO100 User’s Manual
1 - Warranty Registration Card
If any of these items are missing or damaged, please contact Maretron.
2.2 Choosing a Mounting Location
The selection of a suitable mounting location is important for the optimal performance of the
Maretron WSO100. The mounting location and orientation of the WSO100 should be:
1. Level with the earth’s horizontal plane – This gives the WSO100 wind / weather sensor the
best accuracy of wind speed and direction over the widest range of heel angles.
Revision 1.2 Page 1
WSO100 User’s Manual
2. High Enough to have a clear view of the sky to the horizon in all directions unblocked by
sails or boat structures – The WSO100 provides the best readings when wind through it is
unimpeded by sails or structures on the boat.
2.3 Mounting the WSO100
The Maretron WSO100 can be mounted on top of a 1” 14 threads per inch standard marine
pole mount (Section 2.3.1).
2.3.1 Mounting the WSO100 to a Standard Marine Pole Mount
Screw the included WSO100 mounting bracket to the standard marine pole mount. If you do
not have a DSM200 or other display unit capable of configuring installation offset in the
WSO100, ensure that the pole mount is oriented as follows. The pole mount base has three
small holes for mounting screws and one larger hole for the humidity sensor. Ensure that the
small (mounting screw) hole which is nearest the larger (humidity sensor) hole is oriented such
that it faces directly forward in the vessel. If you do have a DSM200 or other display unit
capable of configuring installation offset in the WSO100, you may mount the sensor in any
orientation and adjust for it by configuring the installation offset appropriately (please refer to
the display user’s manual for details).
Route the NMEA 2000® cable through the standard marine pole mount and the pole mount
base and connect it to the WSO100 unit (see Section 2.4 below). Finally, attach the WSO100
to the pole mount base using the included brass mounting screws and lock washers as shown
in Figure 1. Do not use threadlocking compounds containing methacrylate ester, such as
Loctite Red (271), as they will cause stress cracking of the plastic enclosure.
WARNING
• When installing the WSO100 to a standard marine pole mount, be sure
to first screw the WSO100 mounting bracket to the pole mount. Then,
attach the WSO100 to the WSO100 mounting bracket with the three
screws which connect these two components. DO NOT first attach the
WSO100 mounting bracket to the WSO100 with the three screws and
then screw the entire assembly onto the pole mount. Doing this will
put excessive torque on the NMEA 2000 connector from the attached
cable and cause damage to the connector which is not covered under
the product warranty.
• Likewise, when uninstalling the WSO100 from a standard marine pole
mount, be sure to first remove the three screws attaching the
WSO100 to the WSO100 mounting bracket. DO NOT first unscrew the
entire assembly from the pole mount before removing the three
screws. Doing this will put excessive torque on the NMEA 2000
connector from the attached cable and cause damage to the
connector which is not covered under the product warranty.
