Page 12: Autopilot Computer Installation
2.5 Autopilot computer installation The autopilot computer is designed to operate in a location with ambient temperatures below +55°C (+130°F). The autopilot computer units (AC12 and AC42) should be mounted vertically in a place between the control unit and the drive unit. The unit should not be exposed to dripping or splashing water. - Page 13 Refer to the table below for recommended cable sizes. Cable length Drive unit voltage 1. Breaker panel to autopilot computer. 12 V 24 V 2. Autopilot computer to drive unit motor (Length refers to each of the two cables) Up to 3 m (10 ft.) Up to 6 m (20 ft.) Up to 10 m (32 ft.) Up to 16 m (52 ft.)
- Page 14 A SimNet cable is supplied with the autopilot computer. It has a connector only at the control unit end. The other end is prepared for screw terminals. AC12 Board Terminals AC42 Board Terminals Polarity protection The fuse located in the lower left corner of the AC board is not put in its final position when supplied from factory.

A rudder feedback alarm may be the result if the alignment instructions as per Figure 2-5 are neglected. Figure 2-5 Rudder feedback mounting (019356) Note that the transmitter lever has two slots for the transmitter link. The slots enable maximum flexibility to provide the 1:1 mechanical linkage relationship.

2.13 S35 NFU Lever installation The unit is mounted to a bulkhead or panel by two screws from the front. The cable is connected to the autopilot computer according to Figure 2-19. Interchange the Port and Stbd wires to the screw terminals if necessary to make the direction of the lever movement coincide with the direction of the rudder movement. -
Page 27: Simnet
2.15 SimNet The SimNet cable system with very small plugs in both ends makes it easy to run the cables, only 10 mm (3/8”) holes are required through panels and bulkheads. The SimNet accessory program contains the necessary items to make a successful installation. Refer to SimNet cables and accessories, page 33. - Page 28 SimNet must be properly terminated, i.e. unless it is a small system (see Figure 2-20) there must be terminations at each end of the Simrad backbone. The SimNet network has to be terminated according to the number and type of products connected.
