® 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.
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.

WSO100 User’s Manual 2.4 Connecting the WSO100 The Maretron WSO100 provides a connection to an NMEA 2000® interface through a connector that can be found on the bottom of the device (see Figure 2). Figure 2 – WSO100 Interface Connector The NMEA 2000® connector is a five pin male connector (see Figure 3).
® 2.4.1 Checking Connections Once the NMEA 2000® connection to the Maretron WSO100 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 WSO100 The WSO100 has several configurable parameters, which are shown in the following sections.
WSO100 User’s Manual 2.5.7 Advanced Configuration… Certain parameters do not normally need to be set in order 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.
® requires no user configuration. However, some of the WSO100 parameters are user configurable as described below: • • • Installation Offset – As shipped from the factory, the WSO100 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.
WSO100 User’s Manual 4 Maintenance Regular maintenance is important to ensure continued proper operation of the Maretron WSO100. 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 WSO100 enclosure or seals. Do not use any cleaners containing acetone, as they will deteriorate the plastic enclosure. Any spider webs, etc.

® 8 Maretron (2 Year) Limited Warranty Maretron warrants the WSO100 to be free from defects in materials and workmanship for two (2) years from the date of original purchase. If within the applicable period any such products shall be proved to Maretron’s satisfaction to fail to meet the above limited warranty, such products shall be repaired or replaced at Maretron’s option.

® Appendix A – NMEA 2000® Interfacing WSO100 NMEA 2000® Periodic Data Transmitted PGNs PGN 130306 – Wind Data The WSO100 uses this PGN to provide a regular transmission of apparent wind speed and direction data. The factory default for periodic transmission rate is ten times per second. The transmission of this PGN can be disabled (see PGN 126208 – NMEA Request Group Function – Transmission Periodic Rate). Field 1: SID – The sequence identifier field is used to tie related PGNs together.
WSO100 User’s Manual Field 1: 2: 3: 4: 5: 6: SID – The sequence identifier field is used to tie related PGNs together. For example, the WSO100 will transmit identical SIDs for 130306 (Wind Data) and 130311 (Environmental Parameters) to indicate that the readings are linked together (i.e., the data from each PGN was taken at the same time although they are reported at slightly different times).
® 3: Pressure Source – The WSO100 sets this field to a value of 0x00 to indicate that the temperature reading is a reading of atmospheric pressure. 4: Pressure– This field is used to indicate the atmospheric pressure in units of 0.1Pa. 5: Set Humidity – This field is not used by the WSO100 and is set to a value of “Data Not Available”. 6: Reserved Revision 1.
