D6999_1

3. Click the appropriate softkey to adjust the gain control settings.
How do I get a clearer picture of the bottom?
You can get a clearer picture of the bottom using the Bottom Lock function. The normal scrolling bottom display provides a top-down view, referenced from the surface of the water. Bottom lock shows a water column of fixed height, referenced from the bottom that appears flat. It removes bottom detail to provide an image of objects directly above the bottom and is useful when you are looking for objects or fish that are feeding close to the bottom. You can select the bottom lock image to be vertically split with the scrolling bottom image, or to replace the scrolling bottom image.

D7000_1

The bottom lock image appears at the left hand side of the screen. The bottom appears as a straight line, but some features may extend above this line. Depth from the bottom is referenced at the right of the split screen, with the bottom shown as zero. Actual depth is shown in the bottom left of the screen. Bottom lock range is adjusted using the RANGE button. To display bottom lock image: 1. Click Bottom Lock. The bottom lock softkeys are displayed. 2. Click to select the way in which bottom lock is displayed.
How can I see a live image of whats below the boat?
The normal scrolling bottom display shows a historical record of sonar echoes. The AScope screen displays raw sonar data direct from the transducer beam. This gives you a real-time image of bottom structure and any fish directly below the transducer. This function is useful in showing the strength of echo returned from an object. A-Scope also displays the patented Bottom Coverage width indication.
A-Scope Mode 1 Mode 2 Mode 3
A-Scope can be displayed in three modes: Mode 1 -the image is angled outward as the signal width, indicated with dotted lines, increases with depth. Mode 2 - the image expands to take up the entire A-Scope pane, giving greater detail. Mode 3 - the left hand side of the Mode 2 image is expanded to the entire pane. This mode gives the greatest resolution.

D7001_1

If a bottom lock or zoom image is displayed, selecting A-Scope automatically switches them off. If you have split frequency images displayed, A-Scope is automatically displayed in both panes. To display the A-Scope image: 1. Click A-Scope. 2. Click A-Scope to ON. The A-Scope image will appear at the right of the screen. 3. Click right hand A-Scope to required mode.
How do I isolate objects near the bottom?
The white line feature separates echoes from objects near the bottom and the bottom itself. When white line is switched on, the sonar displays echoes differently.

White Line

The strongest echoes are displayed in the background with a thin line on top. All other echoes remain unchanged. To display white line: 1. Click Presentation. 2. Click White Line to ON. The scrolling bottom image will start to display white line from the right of the screen.

D7002_1

How do I get a closer view of an image?
Zoom enlarges all or part of the scrolling bottom display. You should select automatic zoom if you want to keep the bottom in the lower half of the display page. Alternatively you can select the level of zoom to a factor of x2, x4 or x6, proportional to the current range. You can also split the sonar image vertically to show the zoomed area on the left of the screen and the scrolling bottom on the right of the screen.

D7003_1

1. Click Zoom. The Zoom softkeys will be displayed. 2. Click Zoom to On. The Zoom image replaces the scrolling bottom image. 3. Click appropriate softkeys to set up zoom as required.
8.6 How do I mark a position on the screen?
You can use a sonar mark (sm) to indicate a position on the sonar image. The sm is stored in the waypoint list so that you can name it, save it as a waypoint and return to the same spot. A sm is displayed on the sonar image as a solid vertical line with the label sm displayed at intervals along the line. The sm scrolls across the screen with the image.

D7004_1

Sonar marks can be placed: At your boats position. At the cursor position. At a known position.
To place a sm at the boats current position: 1. Select Waypoint/Place Waypoint at Vessel. A new sm will be placed at the boats current position. The mark appears at the right of the screen and scrolls with the image.

.at the cursors position

To place a sm at the cursor position: 1. Select Waypoint/Place Waypoint at Cursor. 2. Move the cursor to where you want to place the sm. 3. Click and a new sm will appear in the selected position.
5. Enter the name for your new sm. Click OK. The waypoint properties dialog box appears.

Routes

A route is made up of a series of waypoint will To make a route a series of waypoints is placed on the chart, or can be selected from the Waypoint List. The boats track can also be saved and then converted to a route. When a route is created it becomes the current route and is displayed on-screen. The current route is maintained even when the system is powered-off. Only one route can be current and is displayed (if it is in the field-of-view) as solid lines connecting waypoints. If
the route is being followed, the current leg is shown as a dotted line and the previous legs are removed from the screen (although the waypoints remain displayed).

Tracks

The track function is used to mark on-screen the trail that the vessel has followed, as if it had left a visible wake. While the track is switched on it is recorded in the system memory. The interval at which track points are made and a line is drawn on-screen between each point. The current track remains on screen, even following a power off/on, until you clear the track.

Appendix B: Radar

This appendix describes the basics of radar and things that can affect the radar picture.

What is radar?

Radio Detection And Ranging (RADAR) is something that is in use all around us, although it is normally invisible. One of the most common uses of radar at sea is to detect the presence of objects, known as targets at a distance, and if they are moving, detect their speed. Until you are familiar with interpreting the radar display, every opportunity should be taken to compare the radar screen patterns with visual targets, such as other boats, buoys and coastal structures. You should practice harbor and coastal navigation during daylight hours and in clear weather conditions

Scanner

The radar scanner unit illuminates targets with microwave energy and then collects the returns from those targets. The scanner includes a sensitive low-noise front end receiver, and a variety of clutter attenuation controls to maintain target resolution. The scanner is adjusted and operated from the display screen. It can be switched between transmit and stand-by modes. It also has a power-saving timed transmit mode which pauses between bursts of transmissions.

Maximum radar range

Maximum radar range is essentially line of sight, so is limited by the height of the scanner and the height of the target as illustrated below:
Earth Radar Rmax h H Rmax = 2.23 ( h + H )
Cliff in nautical miles in metres in metres

D7005_1

maximum radar range radar antenna height target height
Rmax = radar horizon of antenna (a1) + radar horizon of target (a2)
The following table shows typical maximum radar ranges for various radar antenna and target heights. Remember that although the radar horizon is greater than the

optical horizon, the radar can only detect targets if a large enough target is above the radar horizon.

Antenna height (m) 5 5

Target height (m) 3 10
Maximum range (Nm) 10 10.9 8.9 12.0

Range control

The radar picture can be viewed at various scales. The shortest range scale gives a maximum range of 1/8 nm, measured from the default center to the top of the radar picture. The longest range scale gives a maximum range of between 24 and 72 nm depending on the scanner. Long range scales provide the best overview of the boats relationship to land masses, weather fronts and large ship targets in or beyond view. Short range scales provide greater detail of the radar echoes close to the boat, and should be used as the coastline, harbors or other boats in the area are approached. Concentric range rings are included to help in the judging of distances on the radar picture. Their number and spacing are adjusted automatically if the range scale is changed. Range rings can also be turned off.

Standard range scales

Standard ranges that can be selected are shown in the following table:
Maximum range (nm) 0.125 0.25 0.5 0.75 1.24* 48* 72* Number of range rings (nm) 6 Range ring interval (nm) 0.0625 0.125 0.125 0.25 0.25 0.8 12
*The maximum range depends on scanner type. The number of range rings shown in the table is the number to the selected range. Additional range rings are displayed to the edge of the radar picture, at the standard ring interval for the current range, and are visible when the center is offset.
Interpreting the radar picture
Navigational echoes may be large, small bright or faint, depending not only on the size of the object but also on its orientation and surface. Different objects reflect the radar signals in different ways. For example, vertical objects such as cliffs reflect signals better than sloping ones such as sandbanks. High coastlines and mountainous coastal regions can be observed at the longest radar range. However, the first sight of land may be a mountain several miles inland from the coastline. The actual coastline may not appear on the radar until the boat is close to the line of sight distance. The radar indication may not be similar to your visual observation; a nearby small object may appear to be the same size as a distant large object on the radar. However, with experience the approximate size of different objects can be determined by the relative size and brightness of the echoes. Some targets, such as buoys and small boats, can be difficult to differentiate, since they bob and toss about in the waves and do not represent a consistent reflecting surface. Consequently, these echoes have a tendency to fade and brighten, and at times, to

What is SeaTalk?

SeaTalk
The SeaTalk protocol was originally developed by Autohelm (part of Raymarine) and enables compatible instruments to be connected by a single cable carrying power (12 volts, 150 mA) and data in/out, without a central processor, creating a simple network. Additional instruments and functions can be added to a SeaTalk system, simply by plugging them into the network. SeaTalk equipment can also communicate with other non-SeaTalk equipment via the NMEA 0183 standard.

SeaTalk2

SeaTalk2 protocol was developed as the Controller Area Network (CAN) based version of SeaTalk.

What is hsb2?

The high speed bus 2 (hsb2) protocol was developed by Raymarine to enable up to ten multiple displays to be linked together. This enables all of the screens to display data from any unit connected the bus to any other unit which is connected to the bus. This data can be displayed in full, split and overlay screen modes.

What is NMEA?

NMEA 0183
The NMEA 0183 Data Interface Standard was developed by the National Marine Electronics Association of America. It is an international standard to enable equipment from many different manufacturers to be connected together and share information. The NMEA 0183 standard carries similar information to SeaTalk. However it has the important difference in that one cable will only carry information in one direction. For this reason NMEA 0183 is generally used to connect a data receiver and a transmitter together, e.g. a compass sensor transmitting heading to a radar display. This information is passed in sentences, each of which has a three-letter sentence identifier. It is therefore important when checking compatibility between items that the same sentence identifiers are used, e.g. VTG carries Course and Speed Over Ground data, GLL carries latitude and longitude, DBT carries water depth and MWV carries relative wind angle and wind speed data.

Installation Guidelines

EMC installation guidelines
All Raymarine equipment and accessories are designed to best industry standards for use in the recreational 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. Although every effort has been made to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product. The guidelines given here describe the conditions for optimum EMC performance, but it is recognized that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment. For optimum EMC performance, it is recommended that wherever possible: Raymarine equipment and cables connected to it are: At least 3 ft. (1m) from any equipment transmitting, or cables carrying radio signals, e.g. VHF radios, cables and antennas. In the case of Single Side Band (SSB) radios, the distance should be increased to 7 ft. (2m). More than 7 ft. (2m) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element. The equipment is supplied from a separate battery to that used for engine start. 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. Raymarine specified cables are used. 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 The illustration shows typical cable suppression ferrites used with Raymarine equipment. Always use the ferrites supplied by Raymarine.

D6626-1

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
Basic NMEA and RS-232 cabling principles
This section explains some of the basic principles involved with NMEA and RS-232 electrical connections. Knowledge of this information is not required to connect t RNS to your peripheral instrumentation: however, it is provided for the advanced user as a pertinent technical background.

NMEA basics

Most marine electronic devices that output data do so over NMEA ports. These ports are known as a balanced pair, which means that the data signal is carried over two wires (via an RS-422 electrical layer, in computer/datacom terminology). The signal level is determined by calculating the voltage difference between the two wires, hence the NMEA output signal is called a Differential Data Signal (DDS). This DDS should not be confused with Differential Global Positioning System (DGPS), which is a GPS system error correction method. DDS are designed to be error-resistant by keeping the positive and negative leads close together for the entire cable run. This means that they both pick up the same levels of noise, which is ultimately subtracted from the signal, preserving the signals data integrity. NMEA ports typically have four connections (two for each lead); Transmit (positive/ negative) and Receive (positive/negative). Some devices may use a single-direction port, meaning that they can transmit or receive only. To connect one NMEA device to another: 1. Connect device As positive Transmit (Tx+) lead to device Bs positive Receive (Rx+) lead. 2. Connect device As negative Transmit (Tx-) lead to device Bs negative Receive (Rx-) lead. IMPORTANT: When performing the above connection, make sure that you connect the devices directly; DO NOT use the boats DC grounding circuit to carry the Tx- signal. You may encounter a device that does not properly implement the NMEA specification, and shares its Tx- lead with the device DC power ground circuit. In this case, you must still run a cable directly between the Tx- and Rx- leads as previously stated. DO NOT share the DC power ground circuit.

Cables and cable runs

When installing system cables consider the following: All cables should be adequately secured, 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 feed-through should be used. Secure cables in place using tie-wraps or lacing twine. Coil any extra cable and tie it out of the way. Do not pull cables through a bulkhead or deckhead using a cord attached to the connector. This could damage the connections.

Proper cable shielding

For all but the shortest length cable runs, data cables must be shielded to prevent them from picking up electrical noise from other devices, and to keep them from radiating potential interference. If you encounter a data corruption problem, a good place to begin troubleshooting is with the cable shielding, especially on longer cable runs. Make sure the cable shielding hasnt been scraped off by being squeezed through a tight area.
Preventing interference and crosstalk
You should always run data cables: as isolated as possible. as far away from high current carrying AC and DC power lines as possible. as far away from antennas as possible. While it may be convenient to bundle power and data cables together, this causes crosstalk between them, which results in scrambled and unusable data. If you must cross a power cable when running a data cable, try to make the crossing as close to 90o as possible; never run power and data cables parallel within the same bundle. If you have long cable runs planned for data cables, and are using NMEA equipment, use a shielded twisted pair cable to eliminate the danger of interference and crosstalk.

Interfacing RNS

This section shows you how to connect various instruments and devices that can interface with RNS with systems that use: NMEA devices. SeaTalk devices. hsb2 devices.
Connecting RNS to your instruments
The connection between the PC that is running RNS and your instruments is achieved using a 9-pin cable, Raymarine Part No. E86001. One end connects directly to your PCs Serial Port, the other to the various devices.
Connecting directly to a GPS
Connecting RNS to a Global Positioning System (GPS) is the simplest way to get position data. To connect RNS directly to a GPS: 1. Verify that GPS NMEA output is turned ON. 2. Set the GPS datum to WGS84. 3. Using Raymarine Cable Part No.E86001, connect the cables as follows:

Cable color Yellow (Rx) Black (SGnd) Green (Tx) Black (SGnd)
GPS lead NMEA + output may also be labelled Tx, Tx+, Data out +, or NMEA OUT +. Not used Not used NMEA - output may also be labelled TX-, Data out-, NMEA- out, or Ground.
Connecting directly to NMEA equipped instruments
Most instrument systems are equipped to accept incoming NMEA data from your GPS, and will output additional collected NMEA data, such as position, heading, speed, water depth etc. To connect directly to an NMEA equipped instrument system: Connect the cables as follows:
Cable color Yellow (Rx) Black (SGnd) Green (Tx) Black (SGnd) NMEA instrument lead NMEA + output may also be labelled Tx, Tx+, Data out +, or NMEA OUT +. NMEA - Input may also be labelled RX-, Data In -, NMEA IN-, or Ground. NMEA + Input may also be labelled Rx, Rx+, Data In +, or NMEA IN +. NMEA - output may also be labelled TX-, Data out-, NMEA- out, or Ground.
Connecting directly to radar
In order for RNS to be able to display variable range markers (VRMs), electronic bearing lines (EBLs) and cursor information, the radar system you use must be able to output the NMEA RSD string. To display MARPA targets, your radar system must be able to output NMEA TLL or TTM strings. If you are using this feature, make sure your radar system is correctly tracking MARPA targets before connecting it to RNS. To connect RNS directly to a radar system: Connect the cables as follows:
Cable color Yellow (Rx) Black (SGnd) Green (Tx) Black (SGnd) NMEA instrument lead NMEA + output may also be labelled Tx, Tx+, Data out +, or NMEA OUT +. Not used Not used NMEA - output may also be labelled TX-, Data out-, NMEA- out, or Ground.
Connecting directly to an autopilot
The following cabling instructions apply to most autopilot systems, however, you should also refer to the Manufacturers handbook that came with your autopilot. Your autopilot must support NMEA 2.3 strings APA or APB. To connect RNS directly to an autopilot: Connect the cables as follows:
Cable color Yellow (Rx) Black (SGnd) Green (Tx) Black (SGnd) Autopilot lead Not used Not used NMEA + Input may also be labelled Rx, Rx+, Data In+, or NMEA IN+. NMEA - Input may also be labelled Rx-, Data In-, NMEA IN-, or Ground.

Wherever possible Raymarine recommend using a PC with a PCMCIA slot fitted as standard, e.g. a laptop. However, if RNS is being integrated into a desk top PC then it may be necessary to add a Type II compliant PCMCIA adapter. The following are typical installation instructions, but if you experience problems, contact your PC Manufacturer: 1. Install driver CD-ROM supplied with PCMCIA card adapter. 2. Follow the on-screen instructions to install driver software. 3. When the software is successfully installed, shut down and turn off the PC. 4. Open the PC case and plug the PCMCIA card adapter into a spare PCI slot. 5. Close the PC case and power up, as Windows opens the Found New Hardware wizard will appear. Follow the on-screen instructions. 6. Once you have installed the PCMCIA card adapter follow the instructions detailed in To connect an hsb2 PCMCIA card to your PC system: on page 32
Connecting to an Autohelm system
The optimum way to connect RNS to a Raytheon Autohelm system is to use the SeaTalk interface, Raymarine Part No. E85004. To connect RNS directly to an Autohelm system: Connect the cables as follows:
Cable color Yellow (Rx) Black (SGnd) Green (Tx) Black (SGnd) NMEA instrument lead RS-232 + output NMEA - input may also be labelled Rx-, Data IN -, or NMEA IN -, or Ground. NMEA + input may also be labelled Rx, Rx+, Data IN +, or NMEA IN +. NMEA - output may also be labelled Tx -, Data Out -, NMEA OUT-, or Ground.
Connecting to B & G Instruments
RNS connects to the B & G 290, 390, 690, 790 and 2000 instrumentation systems via the B & G Performance Board. Using the performance board has the advantage of enabling RNS to automatically send data back to the B & G unit for remote display. For details of how to connect to other B & G instruments, refer to the section NMEA basics page 22.
To install RNS to a B & G Performance Board: 1. Install a jumper on the performance board between Pin 7 (RTS) and Pin 8 (CTS). 2. Set the Output Baud Rate setting (cross track error calculation value 2) to 6.4 bps. Refer to the relevant Manufacturers handbook for instructions. 3. Connect the cables as follows:
Cable color Yellow (Rx) Black (SGnd) Green (Tx) Black (SGnd) Performance board pin Pin 10 Not used Pin 9 Pin 11
To connect RNS to a B & G NMEA FFD display Connect the cables as follows:
Cable color Yellow (RX) Black (SGnd) Green (Tx) Black (SGnd) NMEA FFD lead color Violet (NMEA output) Not used Not used Black (Ground)
Connecting to KVH Instruments
RNS connects to KVH instruments via the KVH NMEA box or Race box interface devices. Connecting via the Race box has the advantage of automatically sending RNS data back to the KVH system displays. Using the Race box also requires you to use the NMEA box, because the Race box does not propagate all of the NMEA data. For details of how to connect to an NMEA box, refer to the section NMEA basics in this appendix. To connect RNS to a Race box: Connect the cables as follows:

Cable color Yellow (Rx) Black (SGnd) Green (Tx) Black (SGnd) Race box terminal NMEA interface terminal 13 (Tx NMEA) NMEA interface terminal 14 (Negative) Race interface terminal 3 (Rx NMEA) Race interface terminal 5 (Negative)
