The autopilot is mounted between the tiller and a single attachment point on the boat’s structure. It is designed for owner installation and is ready for use after connection to the boat’s 12 V electrical system. ## Operating modes The tiller pilot has four operating modes: * Standby mode: autopilot off, manual steering * Auto mode: autopilot engaged and locked onto a heading * Track mode: autopilot maintaining a track between two waypoints created on a navigation system * Wind mode: autopilot maintaining a stablished angle with the relative wind ## Tiller pilot control Fenix tiller pilot can implement different devices to control the autopilot. {% hint style="info" %} At least one Control Device shall be available with minimum User Functions implemented. {% endhint %} ### Virtuino Mobile App An App based on [Virtuino](https://virtuino.com/) is available to [Android](https://play.google.com/store/apps/details?id=com.virtuino_automations.virtuino\&pcampaignid=web_share) mobiles. This App provides full capability to control tiller pilot. ### $PEMC Serial Interface Fenix Autopilot implements a complete set of $PEMC messages to commission and configure the system from a PC/laptop. * $PEMC are messages following NMEA 0183 rules. * $PEMC messages also allows additional fixed and hand-held Fenix Autopilot compatible control units to be easily connected at alternative steering and control positions. ### NMEA Interface The tiller pilot is NMEA compatible, so it can share data transmitted from other NMEA instruments, track information, from any navigator transmiting NMEA 0183 data (eg. OpenCPN, AVNav), enables the autopilot to provide waypoint control. ## About this Handbook This handbook contains important information about installing, using and maintaining Fenix tiller pilot. To get the best from the system, please read this handbook thoroughly. ## Safety notices #### WARNING: Product installation {% hint style="danger" %} WARNING: Passage making under autopilot control can lead to the relaxation of the permanent watch. Always maintain a permanent watch no matter how clear the sea may appear to be. {% endhint %} #### WARNING: Electrical safety {% hint style="danger" %} Make sure the power supply is switched off before you make any electrical connections. {% endhint %} #### WARNING: Navigation aid {% hint style="danger" %} Although we have designed this product to be accurate and reliable, many factors can affect its performance. As a result, it should only be used as an aid to navigation and should never replace common sense and navigational judgement. Always maintain a permanent watch so you can respond to situations as they develop. {% endhint %} It is the skipper’s responsibility to ensure the safety of the boat at all times by following these basic rules: * [x] Ensure that someone is present at the helm AT ALL TIMES, to take manual control in an emergency. * [x] Make sure that all crew members know how to disengage the autopilot. * [x] Regularly check for other boats and any obstacles to navigation – no matter how clear the sea may appear, a dangerous situation can develop rapidly. * [x] Maintain an accurate record of the boat’s position by using either a navigation aid or visual bearings. * [x] Maintain a continuous plot of your boat’s position on a current chart. Ensure that the locked autopilot heading will steer the boat clear of all obstacles. Make proper allowance for tidal set – the autopilot cannot. * [x] Even when your autopilot is locked onto the desired track using a navigation aid, always maintain a log and make regular positional plots. Navigation signals can produce significant errors under some circumstances and the autopilot will not be able to detect these errors. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://spascual90.gitbook.io/fenix-autopilot/introduction/overview.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
