Overview

The Simrad 000-10186-001 is an AC70 course computer used with Simrad AP70 and AP80 autopilots to control a range of steering systems on board. It supports drive control for a reversible motor or galvanic non-isolated solenoids, and it accepts frequency rudder angle feedback for accurate steering response.

For system integration, it includes an IEC 61162-1 (NMEA 0183) RX/TX channel and is compatible with IEC 61162-1, 2, and 3. There is also a connection for NFU remote control, which is useful when you want simple jog control from a dedicated remote station.

Key features

• Works with Simrad AP70 and AP80 autopilots as the course computer in the steering system.
• Drive output supports reversible motor control or galvanic non-isolated solenoids.
• Frequency rudder angle feedback support for steering accuracy.
• Connection for NFU remote control for straightforward port and starboard jog control.
• IEC 61162-1 (NMEA 0183) RX/TX channel, compatible with IEC 61162-1, 2, and 3.

Installation and setup

This unit is typically mounted below decks in a location that stays dry and allows tidy cable runs to the steering drive, rudder feedback device, and the rest of the autopilot components. Plan the mounting so connectors are easy to reach for service, and route wiring away from high-heat areas and places that can see spray or washdown water.

Before purchase, confirm your steering drive control method matches the supported drive types (reversible motor or non-isolated solenoids) and that your rudder angle feedback signal is the frequency type expected by the system. After installation, the autopilot setup and dockside checks are where you confirm correct steering direction, response, and feedback behavior.

Compatibility and system integration

The AC70 is intended for Simrad AP70 and AP80 autopilot installations where the course computer is the part handling drive control and steering feedback. If you are tying the autopilot into other navigation electronics, use the IEC 61162-1 (NMEA 0183) RX/TX connection where appropriate and verify that your wiring and data settings match the equipment on the boat.

Use on board

This course computer is a good match for boats already set up around an AP70 or AP80 autopilot, especially when the steering drive is controlled by a reversible motor or non-isolated solenoids and rudder angle feedback is part of the installation. It fits well in systems where you want dependable steering control at the helm and the option to add NFU jog control at a remote station.
