Installation accessories
AC12/AC42 Installation Manual
Compass (FC40 or RC42) with 5,5 m (18') SimNet
cable attached
Feedback unit (RF300 or RF25) with transmission rod
and cable attached.
Appropriate drive unit for the installation (unless the
autopilot is going to operate an existing drive unit or
solenoids).
Optional equipment that may have been ordered for
the installation.
2.3 Determine system configuration
It is important to become familiar with the configuration
of the system prior to beginning the installation. An
autopilot basic single station system is shown in Figure
2-1 and a system layout with options is shown in Figure
2-2
Plan your cabling and configure the SimNet network in
accordance with chapter 2.15 on page 26. Pay particular
attention to the autopilot computer/drive unit
combinations.
As most of the units are communicating on a common
network (SimNet) with identical connectors, the
installation is simple. Try to mount the units within the
standard cable length supplied with each unit. SimNet
cables are available from your distributor (see page 33)
for connection to other SimNet devices and cable
extension.
1 On boats powered by outboards or stern drives it
may be difficult to install a rudder feedback unit
(Refer to RF300, RF25 or LF3000 in this manual).
Use of the Virtual Rudder Feedback, VRF™,
algorithms in the software may then be preferred
as this requires no installation of a rudder feedback
