81166_5.book Page 1 Friday, February 2, 2007 11:47 AM Introduction 1 Chapter 1: Introduction SeaTalk is the language used by Raymarine products to share information. This is unique to Raymarine. The PC/SeaTalk/NMEA Interface, by providing conversion between SeaTalk, RayTech PC and NMEA 0183 data formats, allows operation with other manufacturer's equipment and with PCs.

81166_5.book Page 3 Friday, February 2, 2007 11:47 AM Mounting 3 Chapter 2: Mounting Select a suitable location that is: • • • • away from direct contact with water clean and grease-free accessible for cabling reasonably well protected from physical damage. 1. Once a suitable location has been found, thoroughly clean the surface with an alcohol based cleaner. 2. Remove the protective backing from the PC/SeaTalk/NMEA Interface box and firmly press onto the mounting surface. D434-2 3.

Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised.
81166_5.book Page 6 Friday, February 2, 2007 11:47 AM 6 Operation/Wiring supply to our products, 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. • Raymarine specified cables are used at all times. Cutting and rejoining these cables can compromise EMC performance and so must be avoided unless doing so is detailed in the installation manual.

EMC Conformance Always check the installation before going to sea to make sure that it is not affected by radio transmissions, engine starting etc.
81166_5.book Page 8 Friday, February 2, 2007 11:47 AM 8 Operation/Wiring 3.1 NMEA Output Provided you have the appropriate SeaTalk instrumentation, the data listed below is transmitted in NMEA 0183 format for use with non-SeaTalk equipment. Note: NMEA is also output in response to NMEA input.

81166_5.book Page 11 Friday, February 2, 2007 11:47 AM Operation/Wiring 11 3.2 NMEA Input The PC/SeaTalk/NMEA Interface can also be used to convert NMEA 0183 data to SeaTalk. NMEA 0183 data is also retransmitted on NMEA "OUT" in response to NMEA "IN". This allows non-SeaTalk equipment to be connected directly to the SeaTalk bus. Note: Data will not be transmitted to SeaTalk if it is already on present on the SeaTalk bus.

81166_5.book Page 21 Friday, February 2, 2007 11:47 AM Fault Finding 21 Chapter 4: Fault Finding All Raymarine products are comprehensively tested prior to packing and shipment. In the unlikely event that a fault does occur, the following check list should help cure the problem. Fault Cause Action No operation No power supply Check the SeaTalk bus connections are correct between the interface box and the power supply. NMEA data not converted and transmitted onto the SeaTalk bus.
81166_5.book Page 22 Friday, February 2, 2007 11:47 AM 22 Fault Finding Servicing and Safety • Raymarine equipment should be serviced only by authorized Raymarine service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Raymarine product. • Some products generate high voltages, so never handle the cables/connectors when power is being supplied to the equipment.
