Chapter 1: Overview 1 Chapter 1: Overview 1.1 Introduction This handbook provides instructions to assist you to install and set up the following radar scanners: 18" Radome Scanner 24" Radome Scanner A typical Pathfinder Radar system is illustrated below. Scanner Display Unit GPS SeaTalk Compass Junction Box Distribution Panel NMEA 12/24V Supply 12V Supply 12V Supply D4288-2 This handbook is divided into three chapters as follows: Chapter One provides an overview of the scanner installation.
2 Pathfinder Radar Scanners EMC Installation Guidelines All Raytheon 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 configuration is essential to maintain EMC performance and CE compliance.
Chapter 1: Overview 3 If your Raytheon equipment is going to be connected to other equipment using a cable not supplied by Raytheon, a suppression ferrite MUST always be fitted to the cable close to the Raytheon unit. 1.2 Unpacking and Inspecting the Components Unpack your system carefully, to prevent damage to the equipment. It is good practice to save the carton and packing for future use, in case you need to return the unit for service. Check that you have all the correct system components.
4 Pathfinder Radar Scanners 1.3 Selecting the Scanner Unit Site This section provides information that affects the possible locations of the scanner, and its position relative to the display unit and to the power supply. The dimensions of the each scanner unit are shown in the following diagrams.
Chapter 1: Overview 5 large vessel can be detected at a much greater range. For this reason the angular width and relative bearing of any shadow sector must be determined at installation. Sometimes shadowing can be seen by increasing the radar gain until noise is present. Dark sectors indicate possible shadowed areas. This information should be posted near the display unit and operators must be alert for objects in these blind sectors.

Chapter 1: Overview 7 Setting the Radiation Plane The scanner unit should be mounted so that the array rotates parallel to the waterline. The radar beam is approximately 25° wide in the vertical direction, providing good target detection during the vessel’s pitching and rolling. Planing hull vessels, and some displacement hull vessels, adopt a higher bow angle when the vessel is at its cruising speed.
8 Pathfinder Radar Scanners 1.4 Cable Runs You need to consider the following before installing the system cables: – You need to fit the inter-unit cable and the power cable. – All cables should be adequately cleated and protected from physical damage and exposure to heat - avoid running cables through bilges or doorways, or close to moving or hot objects. – Acute bends must be avoided – Where a cable passes through an exposed bulkhead or deckhead, a watertight gland or swan neck tube should be provided.
Chapter 1: Overview 9 Scanner Package Inter-Unit Cable 2D (US) 10m light (2 power cores) 2DE (European) 15m light (2 power cores) 4D 15m heavy (4 power cores) The minimum bends permitted are: Minimum bend, light cable 60 mm (~2.5 in) radius Minimum bend, heavy cable 82 mm (~3.75 in) radius The length of the supplied cable should be sufficient to complete the cable run required on most small vessels.
10 Pathfinder Radar Scanners Note: This table applies to systems using the standard 1.5m power cable. If you extend the power cable you may need to select different inter-unit cable(s), as discussed in the following section Power Cable. Note: If you are mounting the scanner on a sailboat, and will need to unstep the mast, you should install a suitable junction box inside the boat.

Chapter 2: Installing the Scanner 13 Chapter 2: Installing the Scanner 2.1 Radome Scanner Securing the Radome Scanner to the Mounting Surface CAUTION THE DRAIN TUBE MUST ALWAYS BE USED, BUT MAY BE SHORTENED IF NECESSARY 1. Using the paper template supplied with the scanner mounting kit, mark the flat mounting surface with the mounting holes and drain tube hole, and drill the holes as indicated on the template.
14 Pathfinder Radar Scanners Connecting the Radome Scanner CAUTION: Before wiring the scanner unit, make sure that the inter-unit cable is not connected and power is not applied to the display unit. When you have run the inter-unit cable to the scanner location, connect the cable as follows: 1. Loosen the 4 (18") or 7 (24") screws securing the scanner cover. These screws are captive and should remain assembled to the lower flange assembly. Press the radome inwards to release the top.
Chapter 2: Installing the Scanner 15 5. Referring to the following illustration, remove the securing nut (1) from the watertight gland and grommet (2), where the inter-unit cable (3) will enter the base.

16 Pathfinder Radar Scanners Ensure that the flat, ferrite side of the clamp does not trap or pinch any of the cables. Note: on the 24" scanner, the clamp must be contained inside the inner cover. - With the clamp positioned correctly, close the clamp ensuring none of the cores are trapped by the hinge or latch. 9. Connect the 8-way plug (4) to the connector (5). The correct fitting is with the small arrow marked on the body of the plug facing upwards and to the left hand side.
Chapter 2: Installing the Scanner 17 2.2 System Connections Power is supplied to the scanner via the display unit; the power cable is supplied with the display unit, refer to your display unit Owner’s Handbook for details on connecting power. However, you should be aware of the following. Grounding the Radar System It is important that an effective RF ground is connected to the radar system.
18 Pathfinder Radar Scanners Scanner Connection The inter-unit cable is connected to the scanner as described in Section 2.1. If you are using an inter-unit extension cable, connect this to the display unit, and connect the supplied cable to the extension cable. The scanner connector pins are shown in the following diagram, together with the connections and core colours . CAUTION The display connector on the inter-unit cable is a moulded plug that cannot be replaced. DO NOT remove this molded plug.
Chapter 2: Installing the Scanner 19 Display Unit Connection The rear of the Pathfinder display provides the following connection sockets: • Scanner connection • HSB, for connecting to another HSB Series display (such as a chartplotter or second radar display) – not available on SL70 display • SeaTalk, for SeaTalk data input and output and connecting to another HSB Series display (such as a chartplotter or second radar display) • NMEA Output – not available on SL70 display • Power/NMEA Input, for 12V or 2

Chapter 3: Systems Test and Post Installation Alignment 21 Chapter 3: System Tests and Post Installation Alignment Once you have installed your radar scanner and display unit, and made all the connections, you need to check your installation. You can then set up the radar system, align the scanner and check the display timing. Set up, alignment and timing checks are perfomed from the radar system display unit.
22 Pathfinder Radar Scanners Bearing Alignment When the system is correctly installed, you must check the bearing alignment to ensure that targets appear at their correct bearing relative to the ship’s bow, and adjust the alignment if necessary. Display Timing Adjustment The display timing can be affected by the length of the cable used to connect the scanner to the display unit. This in turn affects the short range accuracy shown on the display.
