The SIMRAD HR20 is a hand remote designed to provide convenient remote operation of SIMRAD TP20, TP30, and WP30 Cockpit Autopilots from various locations on a vessel. This device enhances the user's control over their autopilot system, offering flexibility and ease of use, particularly when the main autopilot unit is not within immediate reach. The HR20 is a compact and intuitive tool that integrates seamlessly with existing SIMRAD autopilot setups, allowing for a more dynamic and responsive navigation experience.
The primary function of the SIMRAD HR20 is to act as a remote interface for SIMRAD cockpit autopilots. It allows users to engage and disengage the autopilot, adjust the vessel's course, and initiate advanced maneuvers such as autotacking, all from a handheld unit. This remote capability is crucial for situations where the helmsman needs to move around the boat or when a secondary control point is desired, providing an added layer of convenience and safety.
The HR20 connects to the autopilot system via a 4-way bulkhead socket and cable assembly, which interfaces with the autopilot's NMEA input terminals and the vessel's power supply. This connection ensures reliable communication between the remote and the autopilot, allowing for precise control. The design of the HR20 emphasizes user-friendliness, with clearly labeled buttons for various functions, making it accessible even for those new to remote autopilot operation.
The SIMRAD HR20 offers a range of usage features that simplify autopilot control:
Engaging and Disengaging the Autopilot: To activate the autopilot, the user first steers the vessel to the desired course. Then, a simple press of the "STBY/AUTO" button on the HR20 engages the autopilot. An illuminated LED on the remote confirms that the autopilot is active. To disengage, the user presses the "STBY/AUTO" button again. This straightforward on/off control ensures quick and intuitive management of the autopilot system.
Remote Steering in Standby Mode: Even when the autopilot is in "Standby Mode" (not actively steering the vessel), the HR20 allows for "power steering." The arrowed "Port" and "Starboard" buttons can be used to manually steer the vessel. This feature is particularly useful for making minor course corrections or maneuvering the boat without fully engaging the autopilot, providing a degree of manual control through the autopilot's steering mechanism.
Course Adjustment in Auto Mode: When the autopilot is in "Auto Mode" (actively steering the vessel), the HR20 provides precise course adjustment capabilities. A single press of the "Port" or "Starboard" button will alter the course by 1 degree in the desired direction. For larger adjustments, pressing and holding these buttons will change the course in 10-degree increments. This dual-increment adjustment allows for both fine-tuning and rapid course changes, adapting to various navigational needs.
Autotack Facility: The HR20 includes an "Autotack" feature, which enables the autopilot to automatically tack the vessel through a preset angle. To initiate an autotack, the user presses and holds the "TACK" button. While holding "TACK," they then press either the "Port" or "Starboard" button, depending on the desired tacking direction. This automated maneuver simplifies sailing, especially for single-handed sailors or when navigating in challenging conditions.
Installation Flexibility: The HR20 is designed for a neat installation. It comes with a 4-way bulkhead socket and cable assembly that connects to the vessel's power supply and the autopilot's NMEA input terminals. If a GPS or other NMEA0183 compatible navigational receiver is already interfaced with the autopilot, the HR20's wiring scheme allows for seamless integration. The green (Com) and white (Data) wires of the Hand Remote socket assembly are re-linked to the existing GPS wires, while the blue (NMEA Com - Autopilot) and yellow (NMEA Data - Autopilot) wires from the HR20 replace the removed NMEA cable. The red (12v+ DC) and black (0v) wires connect to a 12v supply. This thoughtful wiring design ensures that the HR20 can be added to an existing system without disrupting other NMEA connections.
Autopilot and NMEA Link Functionality: An important design consideration is that the autopilot and its NMEA link will continue to function even if the HR20 is unplugged from its socket. This ensures that the core navigation system remains operational, providing redundancy and peace of mind in case the remote is accidentally disconnected or removed.
While the SIMRAD HR20 is primarily a control device, its design incorporates aspects that contribute to its longevity and ease of maintenance:
Robust Construction: The HR20 is built to withstand the marine environment, ensuring durability and reliable performance in various weather conditions. Its robust construction minimizes the need for frequent repairs or replacements.
Simple Wiring Diagram: The provided installation and wiring diagram is clear and easy to follow, facilitating correct setup and troubleshooting. Proper installation is key to the device's long-term performance and minimizes potential electrical issues.
Modular Design: The use of a 4-way bulkhead socket and cable assembly allows for easy connection and disconnection. This modularity simplifies installation and, if necessary, replacement of the remote unit or its cable without affecting the entire autopilot system.
Minimal User Intervention: The HR20 is designed for operational simplicity, requiring minimal user intervention beyond its intended control functions. There are no complex settings or calibration procedures required for its daily use, reducing the likelihood of user-induced errors or maintenance needs.
Compatibility with Existing Systems: The HR20's compatibility with existing SIMRAD autopilot models (TP20, TP30, WP30) and its ability to integrate with NMEA0183 compatible navigational receivers mean that users can leverage their current setup without extensive overhauls. This backward compatibility simplifies upgrades and reduces the overall maintenance burden associated with integrating new equipment.
In summary, the SIMRAD HR20 Hand Remote is a valuable accessory for SIMRAD autopilot users, offering enhanced control, flexibility, and convenience. Its intuitive design, comprehensive usage features, and thoughtful integration capabilities make it an essential tool for modern marine navigation.
