Operation and Installation 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.
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 clea n the surface with an alcohol based cleaner.

Operation and Installation 3. Alternatively, the PC/SeaTalk/NMEA Interface box may be attached using the 2 self tapping screws provided. 4. Remove the top of the Interface box by squeezing the lid at each end and pull away from the base. 5.
Chapter 3: Operation/Wiring EMC Installation Guidelines All Raymarine equipment and accessories are designed to the best industry standards for use in the leisure marine environment. Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised.
• 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.
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. Data Apparent Wind Angle Apparent Wind Speed Bearing to Waypoint Course Over Ground (M) Cross Track Error...

Operation and Installation 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 re-transmitted 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.

3.5 Connecting to a PC with RayTech Navigator The PC/SeaTalk/NMEA Interface can be used to connect a SeaTalk system to a personal computer equiped with RayTech Navigator charting software. Connection is via the "RS232 OUT and NMEA IN" terminals, as shown in the following illustration.
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 No operation NMEA data not converted Equipment not set up to and transmitted onto the transmit correct NMEA SeaTalk bus.
