Autopilot Core Pack
This pack includes the Simrad NAC-2
autopilot computer, RF25N rudder feedback unit, Precision-9
solid-state compass, plus all cabling and connectors required to
build an NMEA 2000® network backbone or connect your autopilot
system to an existing NMEA 2000® network. To create a complete
Simrad Continuum autopilot system, just add a hydraulic pump or
mechanical drive unit to suit your steering system, and choose a
dedicated autopilot controller or Simrad multifunction display.
NAC-2 Autopilot Computer
The NAC-2 Autopilot Computer is recommended for boats up to 10
metres (35 feet) in length. It delivers standard power output of
up to eight amps continuous and 16 amps peak, plus a clutch
output; this is suitable to operate low-current drive pumps
including the Simrad RPU80, mechanical drives such as the Simrad
SD10, hydraulic linear drives such as the HLD350, and solenoid
Multiple Control Options
Choose from a range of dedicated autopilot controllers, or
control your autopilot from your existing multifunction display or
glass bridge with full Simrad display integration. Install extra
autopilot stations, ideal for dual-helm vessels, or add the Simrad
WR10 wireless remote for instant steering and autopilot control
from anywhere on board.
RF25N Rudder Feedback Unit
Rudder feedback units are sensors that connect to your rudder
via a mechanical linkage and continuously report actual rudder
position to your autopilot computer – allowing the Simrad
Continuum steering algorithm to make the best-informed steering
decisions possible. These sensors are typically used on boats with
inboard engines, on larger vessels, and in special applications
where Virtual Rudder Feedback may not be suitable. The RF25N
included in this pack connects directly to your boat’s NMEA 2000®
network, simplifying the cabling required for installation.
Simrad Precision-9 Compass
The Precision-9 Compass supplies accurate heading and
rate-of-turn information to your autopilot and other onboard
systems over an NMEA 2000® connection. Heading is determined by an
internal array of solid-state sensors that constantly measure
motion and orientation on nine axes. The Precision-9’s solid state
technology is not only accurate and precise, but also exremely
reliable with no internal moving parts. An easily adjustable
mounting bracket and single-cable connection allow simple
installation aboard any vessel, including up-mast mounting
suitable for interference-free operation with steel hulls.
Automatic Tuning and Calibration
Auto-tuning simplifies setup and ensures optimal steering
performance. Automatic compass calibration improves heading
accuracy as you travel, using data gathered by the Simrad
Precision-9’s internal array of solid-state sensors.
Plug-and-play connectors facilitate easy installation,
minimising the wiring necessary to install your autopilot system.
Industry-standard NMEA 2000® networking offers simple connectivity
to sensors, autopilot controllers, and multifunction displays
located anywhere on board.
