Navigating challenging waters demands equipment that stands up to constant exposure to salt, waves, and extreme conditions. The Simrad AC70 Course Computer steps in as a reliable b ackbone for professional autopilots like the AP70 and AP80 systems, delivering precise control over your vessel's steering. Engineered for rudders driven by reversible motors or non-isolated solenoids, this drive computer processes frequency-based rudder angle feedback to ensure steady, responsive performance on long hauls or in rough seas. Core Features of the Simrad AC70 Robust Drive Control: Handles reversible motors or non-isolated solenoids seamlessly, providing the muscle for hydraulic steering setups common in commercial and workboats. Precision Feedback: Integrates frequency rudder angle sensors for accurate position tracking, minimizing drift and enhancing course-holding even in crosswinds or currents. NFU Connectivity: Supports Non-Follow-Up remote controls, giving operators quick manual override options from the helm or flybridge. NMEA Communication: Features a single-channel IEC 61162-1 (NMEA 0183) RX/TX port, with compatibility for protocols 61162-1, 2, and 3, allowing integration into broader navigation networks for data sharing on heading, wind, and GPS inputs. Power Versatility: Operates on 12-24V DC systems with a 30-amp maximum draw, fitting a wide range of vessel electrical setups. Why Boaters Trust the AC70 for Demanding Operations In the world of marine electronics, reliability isn't optional—it's essential. This course computer shines in high-stakes environments, from offshore fishing charters to supply vessels, by offering stable autopilot performance that reduces crew fatigue during extended voyages. Its compact design simplifies retrofits into existing AP70/AP80 systems, while the built-in safeguards against power surges protect your investment in harsh saltwater conditions. Users report smoother rides with less rudder hunting, thanks to the optimized processing of rudder feedback signals. Pair it with Simrad's ecosystem, and you unlock layered automation: wind vane steering modes, route following, and adaptive gain adjustments that learn your boat's behavior over time. Complete Kit for Seamless Setup Every AC70 package equips you with essentials for straightforward installation: T-Connector for easy network integration. 2-meter power network cable with terminator to maintain signal integrity. 0.6-meter pigtail male connector for quick solenoid or motor hookups. These components cut down wiring hassles, letting installers focus on calibration rather than fabrication. Pro Tips for Optimal AC70 Performance Mount the unit in a dry, ventilated spot away from engine heat. During commissioning, zero in on rudder feedback calibration using your vessel's full lock-to-lock travel—this ensures the autopilot compensates accurately for your hull's hydrodynamics. For multi-station helms, leverage the NFU port to sync joysticks without signal conflicts. Regularly inspect connections for corrosion, a common culprit in marine setups, to sustain peak efficiency.
