Installation

2.1 Unpacking the Box
When unpacking the box containing the Maretron WSO200, you should find the following items:

1 – WSO200 Ultrasonic Wind/Weather Station
1 – Pole Mount Base
3 – Mounting Screws and Lock Washers
1 – WSO200 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 WSO200. The mounting location and orientation of the WSO200 should be:

1. Level with the earth’s horizontal plane – This gives the WSO200 wind/weather sensor the best accuracy of wind speed and direction over the widest range of heel angles.
2. High Enough to have a clear view of the sky to the horizon in all directions unblocked by sails or boat structures – The WSO200 provides the best readings when wind  through it is unimpeded by sails or structures on the boat.

2.3 Mounting the WSO200
The Maretron WSO200 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 WSO200 to a Standard Marine Pole Mount
Screw the included WSO200 mounting bracket to the standard marine pole mount. If you do not have a device capable of configuring installation offset in the WSO200, 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 device capable of configuring installation offset in the WSO200, 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 WSO200 unit (see Section 2.4 below). Finally, attach the WSO200 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 WSO200 to a standard marine pole mount, be sure to first screw the WSO200 mounting bracket to the pole mount. Then, attach the WSO200 to the WSO200 mounting bracket with the three screws which connect these two components. DO NOT first attach the WSO200 mounting bracket to the WSO200 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 WSO200 from a standard marine pole mount, be sure to first remove the three screws attaching the WSO200 to the WSO200 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.

2.4 Connecting the WSO200
The Maretron WSO200 provides a connection to an NMEA 2000® interface through a connector that can be found on the bottom of the device (see Figure 2).

The NMEA 2000® connector is a five-pin male connector (see Figure 3). You connect the WSO200 to an NMEA 2000® network using a Maretron NMEA 2000® cable (or compatible cable) by connecting the female end of the cable to the WSO200 (note the key on the male connector and keyway on the female connector). Be sure the cable is connected securely and that the collar on the cable connector is tightened firmly. Connect the other end of the cable (male) to the NMEA 2000® network in the same manner. The WSO200 is designed such that you can plug or unplug it from an NMEA 2000® network while the power to the network is connected or disconnected. Please follow recommended practices for installing NMEA 2000® network products.

2.4.1 Checking Connections
Once the NMEA 2000® connection to the Maretron WSO200 has been completed, check to see that wind speed information is being properly transmitted by observing an appropriate display. Refer to Section 5, “Troubleshooting”, if no heading information appears.
2.5 Configuring the WSO200
The WSO200 has several configurable parameters, which are shown in the following sections.
If you are not using the default values, then you will need to refer to the corresponding section for configuring the WSO200 appropriately.

The WSO200 can be configured in any of the following ways:

• DSM410 Multifunction Display
• DSM570 Multifunction Display
• N2KAnalyzer Network Analysis / Configuration Software. This will require a Windows PC and one of the following:
  o USB100 NMEA 2000/USB Gateway, or
  o IPG100 Internet Protocol Gateway

2.5.1 Device Label
Program this parameter with a text string which identifies this device. Maretron display products will display this label text when you are selecting data to display.
2.5.2 Installation Offset Calibration
You may compensate the wind direction readings transmitted by the WSO200 in order to create a 0° apparent wind direction when the wind is blowing directly onto the bow of the boat. This compensates for installations where the WSO200 is not aligned exactly with the boat’s centerline.
2.5.3 Wind Data Damping Period
You may adjust the damping that the WSO200 applies to transmitted wind speed and direction readings. The WSO200 comes from the factory preset with a damping period of 1.5 seconds, which should be appropriate for most applications. However, you may tune the damping period to anywhere between 0.1 seconds and 5.0 seconds if you desire.
2.5.4 Barometric Pressure Offset Calibration
If you wish to apply an offset to the barometric pressure reported by the WSO200, you may change the barometric pressure to match the value you wish displayed, which will create and apply an offset to future barometric pressure readings.
2.5.5 Outside Humidity Offset Calibration
If you wish to apply an offset to the humidity reported by the WSO200, you may change the humidity to match the value you wish displayed, which will create and apply an offset to future humidity readings.
2.5.6 Outside Temperature Offset Calibration
If you wish to apply an offset to the temperature reported by the WSO200, you may change the temperature to match the value you wish displayed, which will create and apply an offset to future temperature readings.
2.5.7 Advanced Configuration…
Certain parameters do not normally need to be set for normal operation but are included in an advanced configuration section for use in special situations.
2.5.7.1 Device Instance Configuration
This entry allows you to program the NMEA 2000 device instance for the unit. You usually will not need to modify the default value of “0” unless you have multiple units on the network. Device instance is always used in the Wind PGNs.
2.5.7.2 Instance – Humidity Configuration
This entry allows you to program the NMEA 2000 device instance for the humidity transmitted in PGN 130313. You usually will not need to modify the default value of “0” unless you have multiple humidity sensors on the network.
2.5.7.3 Instance – Pressure Configuration
This entry allows you to program the NMEA 2000 device instance for the air pressure transmitted in PGN 130314. You usually will not need to modify the default value of “0” unless you have multiple pressure sensors on the network.
2.5.7.4 Instance – Temperature Configuration
This entry allows you to program the NMEA 2000 device instance for the temperature transmitted in PGN 130312. You usually will not need to modify the default value of “0” unless you have multiple temperature sensors on the network. Note that the TMP100 module also generates these PGNs.
2.5.7.5 Installation Description Configuration
The WSO200, along with all other certified NMEA 2000 devices, has two user- programmable installation description fields. You may program these fields with information specific to the device, such as date installed, the initials/name of the installer, the physical location of the device, etc. This configuration option will allow you to program the values of these fields.
2.5.7.6 NMEA 2000 PGN Enable/Disable Configuration
The WSO200 is capable of transmitting NMEA 2000® messages. You may individually enable or disable each of these messages. You may also change the rate of transmission of each of these messages if desired.
2.5.7.7 Restore Factory Defaults
Selecting this configuration option causes all stored parameters in the WSO200 to be reset to the values they contained when the unit was manufactured.

Operation

As shipped from the factory, the WSO200 automatically provides apparent wind direction, apparent wind speed, outside air temperature, relative humidity, and barometric pressure and requires no user configuration. However, some of the WSO200 parameters are user configurable as described below:

• Installation Offset – As shipped from the factory, the WSO200 will read 0° apparent wind direction when the wind blows into the sensor directly from the direction of the post nearest the black humidity sensor that protrudes from the bottom of the sensor. If the WSO200 is mounted with this post facing directly towards the bow of the boat, no adjustment is necessary; however, if the sensor is mounted in any other orientation, the installation offset can be used to compensate the apparent wind direction reading such that it will read 0° when the apparent wind is blowing directly into the bow of the vessel.
• Wind Speed Damping Period – As shipped from the factory, the WSO200 uses a damping period of 1.5 seconds to filter short-term variations in wind speed and direction and provide a more stable, usable output. This damping period can be changed by the user to increase or decrease the amount of filtering.
• Periodic Rate of Transmission – As shipped from the factory, the WSO200 transmits PGNs at a periodic rate. Alternatively, a PGN can be disabled by programming its  periodic rate to zero.

Users with direct access to the NMEA 2000® interface may configure these parameters directly through the NMEA 2000® interface. Please refer to Appendix A for a  description of the NMEA 2000® messages used to configure these parameters.

3.1 Ultrasonic Wind Speed Sensing
The wind speed measurement portion of the WSO200 consists of three sets of ultrasonic transducers spaced equally around a horizontally-aligned circle.
The wind speed is measured by measuring the time of flight of an ultrasonic sound pulse generated by one set of sensors and received by the other two sets of sensors. Each of the three sets of sensors takes a turn at being the transmitter, which the remaining two sensors receive the pulse. Wind blowing in the direction of flight of a pulse increases the speed of the pulse by the amount of the wind speed. Measuring the time of flight in both directions between a given pair of transducers allows the speed of sound to be cancelled out of the calculation, making the wind speed computation independent of air temperature and relative humidity. The ultrasonic transducers are robust, yet sensitive instruments. The transducers themselves must be kept free of any coating, such as paint. The WSO200 unit itself, especially the area between the transducers, must be kept clean and free of debris for maximum wind speed and direction accuracy.

Maintenance

Regular maintenance is important to ensure continued proper operation of the Maretron WSO200. Perform the following tasks periodically:

• Clean the unit with a soft cloth. Do not use chemical cleaners as they may remove paint or markings or may corrode the WSO200 enclosure or seals. Do not use any cleaners containing acetone, as they will deteriorate the plastic enclosure. Any spider webs, etc. that accumulate inside the open portion of the WSO200 may be cleaned out with a water spray.
• Ensure that the unit is mounted securely and cannot be moved relative to the mounting surface. If the unit is loose, tighten the mounting screws.
• Check the security of the cable connected to the NMEA 2000® interface and tighten if necessary.

4.1 Replacing the Humidity Sensor
After extended service in an ocean environment, the humidity sensor may need to be replaced.

Please follow these steps to replace the humidity sensor:

1. Remove the two screws holding the existing humidity sensor in place.
2. Remove the existing humidity sensor by grasping the tab on the humidity sensor holder and pulling straight up.
3. Remove the humidity sensor O-ring.
4. Snap the new humidity sensor PCBA into the humidity sensor holder. Please note that the PCBA and the humidity sensor holder are keyed, so that there is only one way to snap them together.
5. Place the new humidity sensor O-ring into the humidity sensor recess on the bottom of the WSO200, centering it on the raised rib.
6. Plug the assembled humidity sensor cover and humidity sensor PCBA into the humidity sensor recess on the bottom of the WSO200 until it is completely seated. Please ensure that the pins on the humidity sensor PCBA plug into the connector inside the WSO200. Also, please note that the humidity sensor cover is keyed so that there is only one way to plug it in.
7. Place the two screws into the screw holes in the humidity sensor and tighten until snug.

Troubleshooting

If you notice unexpected operation of the Maretron WSO200, follow the troubleshooting procedures in this section to remedy simple problems.

if necessary
Ensure that power is supplied to the connected NMEA 2000®  cable
