[. . . ] © Raymarine Ltd 2001. Universal I/O Drive - Installation Guide 3 Introduction Product description Welcome to the installation guide for the Raymarine universal inboard/outboard drive (also known as an I/O or stern drive). This product is intended to operate the boat's steering mechanism as part of a Raymarine autopilot system. CAUTION: This drive is only designed to drive cable operated, power assisted steering systems. Any attempt to install an I/O drive to a non-compatible engine type may void the warranty on both the drive and the engine. The drive operates the power steering valve in the same way as the steering cable. [. . . ] Voltage drops below 10 V, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. Cutting and rejoining these cables can compromise EMC performance and must be avoided unless doing so is detailed in the installation manual. If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position. · · · Suppression ferrites Figure 3 shows typical cable suppression ferrites used with Raymarine equipment. Use the ferrites supplied by Raymarine. Connections to other equipment If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite MUST always be attached to the cable near to the Raymarine unit.
