The drop down options have troubleshooting steps associated to specific gWind devices and scenarios
Basic Inspection and Troubleshooting (all wind sensors)
Visually inspect and verify the wind sensor is freely moving in the wind
Inspect any cable connections related to the wind sensor and instrument display to ensure that there are no loose or chaffed wires or connectors
When trying to troubleshoot the wind sensor, make sure the display is set to apparent wind angle/speed (AWA/AWS)
Power cycle the display and NMEA Network
Ensure the NMEA 2000 device Load Equivalent Numbers (LEN) do not exceed the NMEA 2000 network capability for the network
Ensure the System Software is up to date
Identify if the GND 10 NMEA 2000 and NEXUS status light color and if it is solid or flashing (See GND 10 Owners/Installation Manual for "Status LEDs" code)
Unplug the wind transducer from the GND 10 NEXUS port and plug it into the other NEXUS port, (may require GND 10 to be power cycled, as well)
Check inside the Nexus Field Installable Connector for "wire-to-terminal" assignment and security and for electrical opens / continuity / shorts to other wires in the connector / cable
Requires an Allen Wrench, .90mm hex key (the Allen wrench came with the connector, however it may also be found online or possibly a RC Hobby stores)

gWind Wireless 2 (Current Model)
The gWind Wireless 2 connects wirelessly to a compatible chartplotter or GNX Wind display.
NOTE: The gWind Wireless 2 transducer can be identified by the BLUE colored support shaft of the wind transducer.
The gWind Wireless 2 wind sensor can connect up to 50ft away from the device it is paired to, as long as there is a clear line-of-sight between the devices
If the line-of- sight is obstructed, the signal strength may be diminished or significantly reduced. Positioning & structures, including but not limited to: Device mounting location in interior salons/cabins, Biminis, Fiberglass, Metal, Wood, Carbon Fiber, Kevlar, Sails, Masts, Booms, Rigging, and Instrument pods can have adverse affect to signal strength
When the RSSI signal strength is low (25 and less), the wireless signal can also be disrupted by VHF / HF, Cell phone / tower signals, Wi-Fi and Electro Magnetic Interference
When the gWind Wireless 2 transducer is paired to a single chartplotter or GNX Wind, the wind information will flow via the NMEA 2000 network to other networked devices
NOTE: If a vessel is equipped with more than one GNX Wind instrument or a combination of GNX Wind and compatible chartplotters, DO NOT wirelessly pair multiple devices to the same gWind Wireless 2 transducer at the same time. If that is done, the wind information may be erratic or lost.
