6 DSM300 Operation with PLUS Series Displays

Preface

Purpose

Raymarine DSM300 Digital So under Modules provide echo sounder data that ca n be displayed on Raymarine E Series, C Series, and hsb display units. This handbook describes operating the DSM300 with hsb Series displays. Instructions for using the DSM300 with E Series and C Series displays are available in the handbooks for those products. The DSM300 will not work with older HSB (non-PLUS) displays.

DSM300 Digital Sounder Modules are intended for recreational depth finding and fishfinding purposes. Echo sounder systems require an appropriate Raymarine transducer unit and inter-connecting cable.

To obtain the best results in DSM300 operation and performance, please read this handbook thoroughly. Raymarine’s Technical Services representatives or your local dealer will be available to answer any questions you may have.

SAFETY NOTICE

This equipment must be installed and operated in accordance with the instructions contained in this manual. Failure to do so can result in personal injury and/or navigational inaccuracies. In particular:

Chapter 1: Overview

1.1 Introduction

This handbook describes how to operate the DSM300 Digital Sounder Module with hsb

PLUS (Pathfinder) Series displays. The DSM300 emits and receives sonar signals from a transducer mounted in the water, then interprets and transmits the data to a separate hsb

PLUS (Pathfinder) Series display unit installed in your boat.

D7462-1

Figure 1-1: DSM300 Digital Sounder Module

The DSM300 employs a very high transmission repetition or “ping” rate which, along with the digital adaptive high sample rate receiver, ensures that fish and bottom structure are presented in superb detail and optimal color allocation. The DSM300 digital bandwidth adaptation adjusts the receiver band width dynamically from very wide to very narrow, as required by the actual water conditions. This provides superior fish and bottom detection in all surroundings.

The DSM300 features dual frequency (200 kHz and 50 kHz) operation and— depending on the transducer installed and conditions—up to 1000 watts RMS output power and performance from 3 ft (1m) up to 5000 ft (1700 m).

Note:

Many illustrations in this handbook show example screens. The screen you see on your display depe nds on your system configuration and set up option s, so it may differ from the illustration.

Chapter 2: Getting Started

2.1 Introduction

This chapter provides basic instructions to get you started using the DSM300 Digital Sounder Module with a Raymarine hsb Instructions for operating the DSM300 with a C Series or E Series display are available in the handbooks for those products.

This chapter also describes Simulator mode and helps you to become familiar with the basic functions of the display’s controls in Sonar operation mode. More detailed information on using the controls and operating in Sonar mode is provided in Chapter 4 and Chapter 5, respectively.

Note:

All settings described in this chapter are retained when the unit is powered off. However, there is a one-minute delay from the time you make the setting change to when the DSM300 places it in memory. If you power down the sounder less than one minute after making a change, the setting is lost.

PLUS (Pathfinder) Series display.

2.2 Powering on the Sounder Module

There is no power switch on the DSM300. The unit turns on when the power cord is attached to boat’s power and plugged into the POWER connector on the connector panel.

CAUTION: The DSM300 should be located so that the power cord can be easily removed, if necessary. If the sounder is placed in a difficultto-reach location, Raymarine strongly suggests installing a power switch on the DSM300 power cord at a point where it is easily accessible.

Status LED

The LED on the front panel blinks green when the module is powered on and operating normally. If the unit detects a problem, the LED blinks amber to indicate a warning or red for an error. The number of times the LED blinks is a code representing the nature of the problem. For an explanation of the various error codes, refer to the DSM300 Installation Manual.

2.4 Selecting Repeater Mode

DISPLAY

SONAR

SET UP¬

Depth data that is to be shared over the hsb2 network is sourced from the device that has been designated as the master sonar unit. Only a DSM300 or an hsb

PLUS Series fishfinder display can be a master unit. For the DSM300 master to repeat its sonar image data to a display unit, the display must be designated as the REPEATER.

When using the DSM300 with a PLUS radar or chartplotter display, this is not an issue—the DSM300 is automatically set as the master and the display unit the repeater. However, the DSM300 can also repeat its image data on a fishfinder display. In this case, both units are capable of collecting sonar data. You must tell the display it is to be a repeater for the DSM300 and not a master unit on its own.

If your DSM300 is repeating its sonar data over a PLUS Series radar or chartplotter display, the proper settings are made automatically. You need do nothing else.

However, if your repeater display is a PLUS Series fishfinder, you must tell the unit to be a repeater.

➤ To set the fishfinder display to be the sonar repeater:

1. Press the DISPLAY key until SONAR mode is selected, as described in the

previous section.

2. Press the MENU key.

The Menu soft keys appear.

3. Press the SONAR SET UP soft key.

The Sonar Set Up menu appears.

4. Press the trackpad until the SONAR HSB MODE parameter is highlighted

(selected).

5. Press the REPEATER soft key.

6. Press ENTER. The display unit is now designated as the Repeater.

Details on setting up your DSM300 and display are given in Chapter 3.

2.5 Sonar Mode Display

When you first switch the display unit into Sonar mode, the scrolling bottom graph is displayed. This is a graphical representation of the echoes seen by the DSM300. As time passes, this display scrolls from right to left and becomes a record of the echoes seen. A typical display is shown in Figure 2-2.

The images at the right hand side of the display are the most recent echoes. Some echoes indicate fish, and others show the bottom. It can also indicate bottom structures, such as a reef or shipwreck. The upper and lower depth range limits are shown.

The sonar screen includes a status bar that displays transducer frequency and indicates which auto settings are enabled (Gain, Color Gain, Range, Zoom and Frequency), and alarm status (fish and shallow/deep water depths).

You can customize the sounder by choosing what is displayed and how it is displayed (including language and units). For example, you can set the scroll speed of the bottom graph display, and you can select the range to adjust the depth displayed.

You can view the cursor position and a variety of data (such as speed and depth) from the transducer and other equipment in user-selectable data boxes. These data boxes can be moved around the screen and they can be switched on or off.

Chapter 4 includes details on adjusting the display; other set up options are described in Section 3.4.

Sonar Options

The DSM300 provides controls to select additional modes:

• Frequency – you can select the transducer frequency: 50 kHz for wide cover-

age and deep water, 200 kHz for a detailed view, both frequencies simultaneously or auto-frequency. The default setting is auto-frequency, which determines the optimum frequency of operation based on the current depth.

• Bottom Lock – changes the operating mode to re-set the bottom. It provides a

bottom-up view: the bottom is used as the reference, its image is flattened and depths are displayed here. Bottom lock mode is used primarily to filter out the bottom structure and display fish details only.

• A-Scope – displays a real-time image of the bottom structure and fish directly

below the transducer. The A-Scope window also displays the patented Bottom Coverage width indication.

• Zoom – enlarges all or part of the bottom graph display. You can select x2, x4,

or x6 magnification and the zoom area can be automatically or manually adjusted.

20 DSM300 Operation with PLUS Series Displays

You can select the Zoom or Bottom Lock image to be displayed in place of the regular bottom graph display. Alternatively, you can set the display window to be split vertically with the bottom graph displayed in the right hand screen and the Zoom or Bottom Lock image displayed in the left hand screen. See Figure 2-4.

If you choose dual frequency, the scrolling bottom graph is displayed in both frequencies, split horizontally. Zoom, Bottom Lock, or A-Scope can be displayed with the dual frequency graph.

All of these options are available when the sonar data is displayed in a half-screen window.

Sounder Functions

The DSM300 includes the following functions:

• Automatic or manual selection of scroll speed for bottom graph display

• Automatic or manual selection of transducer frequency

• Automatic or manual selection of depth range limits

• Automatic or manual selection of Gain, Color Gain, and STC settings

• Set up alarms for Fish, Shallow water and Deep water

3.1 Introduction

Once you have installed your DSM300 and are familiar with its basic operation (described in Chapter 1 and Chapter 2), you need to set it up so that it displays information according to your preferences.

Note:

This chapter describes using th e DSM300 Digital Sounder Module with a Raymarine

PLUS (Pathfinder) Series display. Instructions for setting up the DSM300 with a C Se-

hsb ries or E Series display are available in the handbooks for those products.

This is achieved using the soft key controls that are displayed when you press the

MENU key.

In most cases, you will only need to use the MENU key options when you first set up your system. As you become more familiar with your system, you may decide to customize some aspects, such as the screen and help setting.

Note:

This chapter covers the following topics:

• Changing the default set up parameters

• Sounder specific parameter functions and default settings

You should check the functions of the parameters and decide on the new settings before making the changes.

3.2 Changing the Set Up Parameters

The set up parameters are divided into two sections:

•

System, to control the aspects of the system that are not specific to the

sounder module.

•

Sonar, to control the Sonar-mode display preferences, including HSB mode,

calibration, and simulator.

This section provides instructions for displaying and changing the default values. The following sections list the parameters and their possible settings and describe the function of each parameter in turn.

Data Boxes

Press the SELECT BOXES soft key to display the data box sub-menu. This enables you to select up to 6 data boxes that you can display on the sounder.

Notes: (1)

Data boxes provide regularly used data in a compact form so that most of the graphics can still be seen. The ones you select here can be turned on and off as a group during normal operation, and you can also move them around the screen individually using the context-sensitive cursor. See “Viewing Data Boxes” on page 50.

A fixed set of sixteen (nine in the monochrome displays) of these data

items are available for display in the Nav Data half-screen window.

(2)

In addition to these grouped data boxes, boxes for the cursor readout, VRM/EBL data, waypoint data, MOB data and simulator status are displayed when selected or when the appropriate function is active.

(3)

Radar data is available only if radar equipment is installed and connected.

Bearing Mode

The mode (magnetic or true) of all the bearing and heading data displayed. This is indicated in the radar status bar after the heading value, if displayed.

28 DSM300 Operation with PLUS Series Displays

Cursor Reference

The mode of the bearing data displayed for the cursor readout. The bearing information can be displayed in either of two forms:

• Relative: The bearing relative to your boat’s heading.

• Mag/True: The actual bearing in either degrees magnetic or degrees true. This

option is only available in Radar mode if your system includes a radar display and you have heading data from a compass.

If you choose this mode, the selection you made for the previous parameter (Bearing Mode), °M or °T, is displayed in the cursor (Rng/Brg) data boxes. The current units are shown for the heading value in the status bar at the top of the screen.

Cursor Readout

This option controls whether radar cursor data is shown in latitude and longitude or in range and bearing. Alternatively you can show both types of readout in separate boxes or turn the cursor data box off.

You can also turn the cursor readout box(es) on and off during normal operation, via the SCREEN default soft key.

Day/Night

This option enables you to change the display between day and night modes.

On a color LCD, NIGHT mode uses a different color palette, more suited to night time viewing. The default setting is DAY.

For monochrome displays, the normal DAY presentation displays black targets on a white background. If you select NIGHT, the picture is reversed, so that white targets are shown on a black background to reduce the intensity of the image.

Help

When Help is set to ON, a prompt appears when selecting a soft key or menu choice and when using the context-sensitive cursor. The help message is cleared when an action is selected.

Soft Keys

When the Soft Keys option is set to ON, the default soft keys are displayed if no other operation is in progress.

Chapter 3: System Setup 29

When the Soft Keys option is set to OFF, the default soft keys are only displayed when a soft key is pressed and they disappear if no operation is performed for 10 seconds.

Key Beep

This option controls whether or not the keys sound a tone when you press them.

MOB Data

This option controls whether MOB data is based on position data, or on dead reckoning (DR). Dead reckoning normally provides a better indication of the course to an object in the water, on the assumption that your boat and the object are both subject to the same tide and wind effects.

Autopilot Pop Up

This option controls whether or not the autopilot pop up is displayed. When set to ON, when the status and locked heading of the autopilot changes, they are displayed in a pop up box. The box is removed from the display after two seconds. When Autopilot Pop set to OFF, the pop up box is disabled.

Menu Timeout Period

With no timeout set, menus and soft key labels remain displayed until you clear them by pressing ENTER, CLEAR or the appropriate dedicated key.

If you set a value here, the menus and soft key labels are cleared if a key has not been pressed for the specified number of seconds.

This setting does not affect the default soft key labels, which are controlled by the Soft Keys option (see above).

Units

You can set the units for speed, depth, and temperature. The units you set will be used to display all data , including information received from other instrument s on the system. However, the distance units do not affect the instrumented range of the radar, which is always in nautical miles.

Note:

The ‘Units’ values set here are also used in the other display modes.

30 DSM300 Operation with PLUS Series Displays

Variation Source

The variation value is the difference between True a nd Magnetic direction data for heading or bearing values. The Variation Source option provides soft keys for selecting Auto or Manual variation mode, displays the current variation value for each and highlights the currently selected mode.

Auto Mode

If you select Auto mode, the unit obtains the value of variation automatically, normally from received data. The variation value that is used depends on the data available and is selected in the following order of priority:

1. Variation value from the same source as the heading data:

• If heading data is being taken from NMEA, then variation is also taken

from NMEA

• If heading is taken from SeaTalk, then SeaTalk variation is used

2. Variation value from a different source:

• If heading data is being taken from NMEA, but no NMEA variation is avail-

able, then variation is taken from SeaTalk

• If heading is taken from SeaTalk, but no SeaTalk variation is available,

then variation is taken from NMEA

3. A calculated variation value, using position data, if no SeaTalk or NMEA value is available

4. The current manual variation value, if no SeaTalk or NMEA value and no position data is available

Manual Mode

If you select Manual mode, by pressing either of the MANUAL keys, you can specify the local variation value according to the area in which you are operating. Press the appropriate MANUAL key to adjust the variation up or down, to a maximum of 30° East or West.

This value is then transmitted to any other SeaTalk instruments on your system. It is retained if you turn the display off and on again.

In Manual mode, incoming NMEA variation is ignored. However, if the variation is changed on another SeaTalk instrument, the new value is used and the manual value that is displayed is updated.

Note:

The Manual variation value defaults to 0°, so it is important to set up a value if vari-

ation is not available from an external source.

Chapter 3: System Setup 31

Bridge NMEA Heading

The display unit sends NMEA input data to the SeaTalk bus. The Bridge NMEA Heading option can be used to prevent NMEA heading data being bridged onto the SeaTalk bus.

For example, if you have a course computer connected on SeaTalk and NMEA, and an active compass connected on NMEA (for MARPA), SeaTalk data overrides NMEA data in the course computer.

You should therefore switch OFF the Bridge NMEA Heading option to ensure the course computer receives the same NMEA heading input as the rest of the system.

NMEA-Out Set Up

This option lets you disable the transmission of specific NMEA sentences, which may be necessary if you have other instruments sending the same data as your sounder.

For example, if the DPT (depth) sentence is set ON but the sounder’s transducer is designed to sense temperature and speed only, the depth value will be transmitted as zero. If you also have an ST60 Depth instrument installed, there may be confusion between the zero depth sent by the sounder and the actual depth sent by the ST60. Turning OFF the DPT sentence disables the reading from the sounder.

The factory default for all NMEA sentences is transmission ON. Disable the sentence by selecting the OFF soft key.

The following table displays the available NMEA sentences and their meanings. Table 3-2: NMEA Sentences

Depth Offset value in Sonar Setup.

Cursor Echo

You can set up an integrated system so that radar and chartplotter displays connected via SeaTalk can display each other’s cursors. Cursor echo functions so that you can display a chart cursor on the radar picture, or a radar cursor on the chart picture (you cannot display a remote radar cursor in a radar window nor can you display a remote chart cursor in a chart window). When the appropriate opt ions are switched on, each display show s its own cursor, plus the cursor of the other display with appropriate cursor text (RDR or CHRT) to indicate its origin. This means that you could move the cursor over a target on the radar display and check the identity of the target by looking at the radar cursor position on the chartplotter.

Press the CURSOR ECHO soft key to display the cursor transfer soft keys. The following options can be toggled ON or OFF:

Chapter 3: System Setup 33

• Radar Cursor In: displays the cursor from another radar on the chart display or chart window (default - OFF).

• Chart Cursor In: displays the cursor from another or chartplotter on the radar display or radar window (default - OFF).

Note:

The remote display must have SeaTalk Cursor Out enabled.

• SeaTalk Cursor Out: enables the output, onto SeaTalk, of the display’s own cursor (default - OFF).

• Cursor Echo Local: echoes the cursor position between open windows on the same display (default - ON).

If you set the options to OFF, no cursor echo information is displayed.

Date and Time Settings

Set your preferred date format (DD/MM/YY or MM/DD/YY) and time format (12 or 24 hour). If you wish to display local time, use the soft keys to change from UTC to the desired time offset. This can be up to plus or minus 12 hours, in hourly steps.

GPS SOG/COG Filter

The SOG/COG filter averages the velocity vectors to compensate for the oscillating motion of the boat, giving a clearer indication of the boat’s course and speed. The filter does not affect the calculation of the GPS position. The velocity vectors calculated from the GPS Signal give an instantaneous measure of speed and direction of the GPS antenna. The COG and SOG can therefore seem erratic under certain conditions. For example, when a boat is moving slowly through rough seas, the antenna moves from side to side as well as in the direction of the boat.

Slow moving boats, or boats sailing in rough seas will benefit from a high setting, whereas a power boat that can quickly change speed and direction will benefit from a low setting.

Select the SOG/COG filter setting as required. This can be set to HIGH, MEDIUM or LOW.

Compass Set Up

This option is used to calibrat e a Raymarine heading sensor such as the Pathfinder Smart Heading System. Controls are provided for LINEARISE COMPASS, which detects and corrects for heading errors caused by metal objects, and ALIGN HEADING, which matches the displayed heading to a known heading or transit.

Refer to the Handbook supplied with your heading sensor for more details.

34 DSM300 Operation with PLUS Series Displays

Language

Select the language in which you wish information to be displayed. The selected language will be used for screen text, labels, menus, and options, but will not affect the letters displayed by the context-sensitive cursor. The language setting also affects the display format for lat/long position information.

Simulator

The simulator enables you to operate your display without data from the transducer and/or external data sources. The system set up simulator options have the following functions:

• Data provides simulated numerical data, and a waypoint display.

• Radar provides simulated radar picture, with example targets. The picture

does not change if you change the range, although the range rings are adjusted (see radar documentation).

• Both provides simulated data and radar picture. When the simulator is switched on, a SIMULATOR data box is displayed during

operation, showing the simulation selected.

Sonar simulator mode is set in the Sonar setup menu, described in Section 3.4.

Target Depth ID

You can select whether the depth is shown for sonar echoes displayed on the screen. When Target Depth ID is set to ON, the depth is displayed just above each fish echo. When set to OFF, the depth of each echo is not displayed.

Color Bar

The color bar indicates the range of echoes displayed in each color (shade of gray for monochrome displays). When set to ON the color bar is displayed on the right hand side of the display.

Depth Digit Size

The depth under the boat is displayed in the bottom left hand corner of the display. You can select small or large digits for the depth display.

Sonar HSB Mode

Note:

This parameter only pertains when the display to which you are outputting DSM300 image data is a PLUS Series fishfinder. If your display is a PLUS Series radar or chartplotter display, the REPEATER setting is automatically selected and cannot be changed.

The Sonar HSB Mode setting designates whether the display showing sounder data is the MASTER unit from which depth data is to be sourced or a REPEATER of sonar data received from a master unit. Only one unit should be designated the master at a time.

36 DSM300 Operation with PLUS Series Displays

Note:

Ensure that there is only one sonar master unit on the hsb2 network. Having more

than one master unit will cause unpredictable results.

A sonar MASTER unit is connected directly to the transducer. Only a DSM300 or a PLUS Series fishfinder display can be designated as the master. A REPEATER display is connected via hsb

to the master unit so it can display sonar data the master has collected. A REPEATER can be a radar, chartplotter or fishfinder display. Because the DSM300 does not have a display of its own, the DSM300 is always designated as the MASTER. Therefore, all display units showing sonar data from the DSM300 must be designated as a REPEATER.

This is not an issue when showing DSM300 data on a radar or chart display because these units can never be a sonar master. In this case, the DSM300 is automatically set as the master and the display unit as the repeater. In fact, the MASTER selection is grayed out when the sounder module is connected to a PLUS Series radar or chart display.

However, if the display unit is a PLUS Series fishfinder, you are given a choice. You must set the fishfinder display to REPEATER so that there is no conflict on the hsb network (the DSM300 is always designated as a master). You would only select MASTER when you want to control the PLUS Series fishfinder display rather than the DSM300. In this case, the fishfinder display unit must have its own transducer connected and the DSM300 must be powered off or have its HSB cable disconnected (thus removing it from the hsb

If you switch the PLUS Series fishfinder display from REPEATER to MASTER, you must remove the DSM300 from the hsb the changes to take effect.

Summary

1. When the display is a PLUS Series radar or chart unit, you can ignore this

parameter; the REPEATER setting is made for you automatically.

select REPEATER.

3. When the display is a PLUS Series fishfinder and you want the display to show

its own sonar data rather than that of the DSM300, select MASTER. In this scenario, the DSM300 must be powered off or be physically removed from the

hsb

network.

Depth Offset

The depth offset is added to the measured depth value before it is displayed. You can specify the depth as a positive value (WATERLINE OFFSET) or a negative value (KEEL OFFSET). The depth offset can be set adjusted in 0.1 increments of the units

Chapter 3: System Setup 37

you have assigned for Depth Units in the setup parameters of the display unit: meters, fathoms, or feet.

Speed Calibrate

If the transducer is equipped with a speed paddle wheel, the DSM300 calculates the speed of the boat through the water. The speed calibrate option enables you to adjust the displayed speed so that it matches your actual speed through the water. You can adjust the displayed speed from 1% to 200%.

If the sounder reading is too low, set Speed Calibration to more than 100%. If the sounder reading is too high, set Speed Calibration to less than 100%.

Temperature Calibrate

If the transducer is equipped with a thermistor, the DSM300 calculates the temperature of the water. The temperature calibrate option enables you to adjust the displayed temperature. You can adjust the displayed temperature by –9.0°F to +9.0°F.

Sonar History

Sonar History determines the number of data sample columns that appear on the screen at one time. The options are: SMALL, which displays 240 columns of data or LARGE, which shows 480 columns.

Information displayed in a single column using the LARGE setting would occupy two columns with SMALL. As a result, twice as much data history is displayed under the LARGE setting. Data displayed using SMALL appears wider and scrolls across the screen faster.

Sonar Interference Rejection

Two or more sonar-equipped boats operating within range of each other can create interference on the sounder screen. This usually appears as vertical streaks in the water that do not represent actual targets.

The DSM300 includes a SONAR INT REJ option that can reduce such interference, either manually or automatically. LOW rejects only a small amount of the extraneous objects. Use this setting when you want to be sure that what has been removed are really false returns. HIGH cleans up much more interference but can degrade the appearance of actual targets. AUTOMATIC selects the best rejection level for you.

The default setting is AUTOMATIC.

38 DSM300 Operation with PLUS Series Displays

Sonar Simulator

The simulator enables you to operate your display without data from the transducer, in order to become familiar with the sounder features and functions.

All controls are functional in Simulator mode with the exception of STC.

Contrast set > 30% restored to 30% Contrast set > 70% restored to 70%

Brightness and Color Settings (Color Displays)

The MULTI key on a color LCD unit provides controls to set up the display colors and brightness. You can choose the background color and the color threshold; color threshold lets you determine which echoes are displayed, by selecting the minimum color strength the sounder uses.

You can also select the color set, for a bold or soft color palette. The brightness of the screen can be adjusted over a wide range, suitable for viewing in daylight (high brightness level) or at night (low brightness level).

The key lighting is automatically adjusted as you alter the screen lighting, so that you can always find the keys. If you set the backlight to a high level, the key lighting is dimmed; if you set the backlight to a low level, the key lighting level is increased.

4.4 Display Control Functions

Sonar mode automatically locates the bottom and displays the information using an appropriate scroll speed and range. However, controls are provided so you can adjust scroll speed and range. You can also select the transducer frequency and select certain data for display. This section describes how to use the controls to set-up your sounder display:

• Viewing databoxes

• Changing the scroll speed

• Changing the range

• Selecting the power setting

• Selecting the frequency

In addition this section describes how to select the Sonar mode display options.

• Display Bottom Lock

• Display A-Scope

• Zoom an area of the image.

Viewing Data Boxes

The cursor data box and a group of up to six data boxes can be displayed if the information is available on your system. You select which data is displayed in the boxes during system set up as described in Chapter 3. The default data box positions are along the bottom of the display. Each box can be moved to the desired position on the screen using the context-sensitive cursor.

Chapter 4: Basic Display Controls 51

To switch data boxes on and off as a group you need to go to Chart mode. Switching the databoxes on/off in Chart mode also affects their display in Sonar mode and vice-versa. You can switch them off and on individually using the System Set Up menu, as described in Section 3.3.

Changing the Scroll Speed

The standard fishfinder display is the scrolling bottom image. This is a graphical representation of the echoes seen by the sounder. New information appears at the right hand side of the display and scrolls to the left.

The speed at which the display scrolls is adjustable. As illustrated in Figure 4-7 , if you select a faster speed, more detail is displayed and is useful when you are looking for fish; if you select a slower speed the information remains on the display for longer.

Figure 4-7: Effect of the Scroll Speed

The DSM300 defaults to manual scroll adjustment at full speed (100%). Use the trackpad to decrease the scroll speed in 10% increments down to 0% (pause). Unlike automatic adjustment, manual scroll speed is not related to boat speed over the bottom.

Or you can have the sounder automatically adjust the scroll speed, based on boat speed. If you select automatic adjustment, the scroll speed is related to boat speed as follows:

• Less than, or equal to 0.5 kts, scroll speed is constant at 10%

• Between 0.5–15 kts, scroll speed varies linearly with boat speed

• Greater than 15 kts, scroll speed is constant at 100%

POWER

AUTO

Selecting the Power Setting

The POWER soft key provides adjustment of the transducer signal. When AUTO is selected (default), the sounder automatically determines the optimal power setting based on the current depth, speed, and (bottom) signal strength. When AUTO is selected the current automatic power setting is indicated in the top status line by an L (low) or H (high).

If, however, you wish to manually adjust the power to suit current conditions, you can select either LO or HI power. LO power (100 W) is normally used in depth ranges less than 8 ft (2.4 m) and HI power (600 or 1000 W, depending on your transducer) is typically selected for depths greater than 12 ft (3.7 m).

Selecting the Frequency

The DSM300 uses dual frequency sonar—50 kHz and 200 kHz—and can be used in either auto or manual modes.

The DSM300 can automatically select the appropriate frequency, based on the current display range. As the depth increases while in Auto Frequency mode, the sounder module shifts from 200 kHz to 50 kHz at 250 ft (80 m). As the depth decreases, the sounder module switches from 50 kHz to 200 kHz at 150 ft (50 m).

The Auto Frequency setting is also useful for automatically searching for bottom.

Chapter 4: Basic Display Controls 55

Alternatively, you can manually select either frequency, or both frequencies simultaneously (split frequency). Each is suitable for a particular purpose:

50 kHz Frequency

When using this frequency, the transducer scans a wide area. The 50 kHz signal penetrates water well, so is good for use in deep water.

200 kHz Frequency

When using this frequency, the transducer scans a narrower area, but produces a more detailed view. The 200 kHz signal is good for finding fish near the bottom or close together. It is better for use in shallow water.

Split Frequency

The transducer can operate in both 50 kHz and 200 kHz frequencies at the same time. If you choose split frequency operation, the scrolling bottom display is split horizontally; the upper half shows the 200 kHz detailed view and the lower half shows the 50 kHz image.

➤ To change the frequency:

FREQUENCY

1. Press the FREQUENCY soft key. The frequency selection soft keys are displayed.

2. Press the appropriate soft key – 50 KHZ, 200 KHZ or SPLIT. The scrolling bottom is displayed in the selected frequency. If you choose split, the scrolling bottom is displayed in both frequencies with 200 kHz in the upper window and 50 kHz in the lower window.

3. If desired, press the AUTO FREQUENCY soft key to set AUTO mode ON. AUTO frequency is indicated by the letter F in the status bar.

4. Press

ENTER or CLEAR to return to the default display.

You can choose the split frequency display with the sonar display options, Bottom Lock, A-Scope, or Zoom.

Using Bottom Lock

The 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 fish that feed close to the bottom.

You can select the Bottom Lock image to be vertically split with the scrolling bottom display or it can replace the scrolling bottom display.

56 DSM300 Operation with PLUS Series Displays

As illustrated in Figure 4-8 , the bottom is shown as a straight line. Note that some bottom features may extend above this line. The actual depth reading is given in the bottom left hand corner of the Bottom Lock display.

Range intervals on Bottom Lock are measured up from the bottom (rather than down from the surface). Thus, the bottom is shown as zero and the top number indicates the maximum distance above the bottom being displayed. You can adjust the Bottom Lock range.

If the A-Scope or Zoom image was displayed, selecting Bottom Lock automatically switches OFF A-Scope and Zoom. If you have split frequency selected, the Bottom Lock image is displayed in both frequency windows.

If Target Depth ID is ON, the target depth is displayed as distance from the bottom. See “Target Depth ID” on page 35.

➤ To display the Bottom Lock image:

Chapter 5: Sonar Mode Operation 63

Chapter 5: Sonar Mode Operation

5.1 Introduction

Basic operation, including a description of the diff erent display options, was given in Chapter 4. This chapter explains how to use the display unit to show sonar data. It describes how to fine-tune the image and use the controls to get additional information.

Note:

This chapter describes using the DSM300 Digital Sounder Module with a Rayma-

PLUS (Pathfinder) Series display. Instructions for operating the DSM300 with a C

rine hsb Series or E Series display are available in the handbooks for those products.

This chapter covers the following topics:

• Interpreting and Adjusting the Sounder Image, including fish and bottom

indications, using the white line feature and adjusting gain (sensitivity)

• Viewing Data Windows

• Setting up and Using Alarms for fish, shallow water and deep water

• Using a VRM to Determine Depth and Distance from Boat to a particular spot

• Placing Waypoints

• Using the Man Overboard (MOB) function

Note:

The settings described in this chapter are retained when the unit is powered off. However, there is a one-minute delay from the time you change the setting to when the DSM300 places it in memory. If you power down the sounder less than one minute after making a change, the setting is lost.

Many of the parameters on the DSM300 have both manual and automatic modes. The automatic setting takes advantage the hardware’s advanced digital technology. As a result, the sounder typically performs better in automatic mode than in manual. For better performance, Raymarine recommends that you select AUTO mode wherever it is an option.

64 DSM300 Operation with PLUS Series Displays

5.2 Interpreting and Adjusting the Sounder Image

The DSM300 uses sound waves to find fish and show bottom structure. The transducer sends high-frequency sound waves into the water; these sound waves strike fish, the bottom, or other objects in the water and return as echoes. The DSM300 interprets these echoes to present an image of the fish and bottom.

The strength of echoes is indicated by different colors (or shades of gray in monochrome displays). You can use this information to determine the size of fish and the bottom structure. Other objects in the water, such as debris and air bubbles, also return echoes; these echoes are generally weaker than the fish or bottom echoes and produce background noise or clutter on the display.

The digital sounder provides controls to reduce the background noise and to adjust the way in which echoes of different strengths are displayed. The color displays also let you select the background color and remove the display colors for weaker echoes.

The sounder provides a White Line feature which helps to distinguish between the bottom and fish (or other objects such as weed) that are close to the bottom.

Target Indications

When the sounder detects a target echo such as a fish, it displays a representative image on t he LCD. The shape and size of this image is influenced by a combination of factors:

Boat speed

The shape of the target changes along with your speed. Slower speeds return flatter, more horizontal images. As your boat’s speed increases, the image will tend to thicken and arch slightly.

The depth of the target

The closer the target to the surface the larger the image on screen.

To display the depth of individual targets, switch on the TARGET DEPTH ID from the menu, as described on page 44.

The size of the target

The larger the target, the larger the return on the fishfinder display. The size of a fish target is however dependent upon the size of the fish’s swim bladder rather than its overall size. This swim bladder will vary in size between different breeds of fish.

Chapter 5: Sonar Mode Operation 65

The frequency of the transducer

The same target will appear differently when the transducer frequency is changed. Generally, the lower the frequency the broader the image.

Using White Line

The White Line feature separates echoes from fish near the bottom and the bottom itself. When the White Line is switched on, the sounder displays the echoes differently.

On color LCDs, the strongest echoes are displayed in the background color with a thin line on top. All other echoes remain unchanged.

On monochrome displays, the weakest echoes continue to be displayed in the background color (white), but colors for the other signal are reversed. Thus, from the strongest to the second weakest the colors are: light gray with a thin black li ne on top, dark gray, black.

➤ To switch the white line feature on and off:

MULTI

WHT LINE

OFF ON

1. Press the MULTI key (knob). The WHT LIN E soft key is displayed.

2. Press the WHT LINE soft key to toggle the white line feature ON or OFF.

Adjusting Display Gain (Sensitivity)

The sounder provides controls for GAIN, COLOR GAIN, and STC. These controls, accessed from the GAIN key (or GAIN knob on radar CRT units), are used to reduce background noise and determine how different strength echoes are shown. You can set automatic adjustment of each of these parameters or manually adjust the settings using the trackpad.

Note:

Because the changes to the settings take effect immediately, you cannot revert to

the previous settings by pressing CLEAR.

5. When you have set all the controls to the levels you desire, press ENTER or

CLEAR to return to the default display.

Gain

The GAIN, or sensitivity, of the display adjusts background noise by varying echo strength for display. The value of the gain control determines the strength above which echoes are displayed. If the gain is low only the strongest echoes are displayed. As the gain is increased, wea ker echoes (f rom air bubbles, for example) are also displayed.

MANUAL

80%

GAIN

Pressing the GAIN soft key cycles the sounder from manual through three levels of automatic gain adjustment.

Manual gain should be set high enough to see fish and bottom detail but without too much background noise. Generally, a high gain is used in deep and/or clear water; a low gain in shallow and/or murky water.

The automatic gain modes finds the ideal sensitivity level for you, based on depth and water conditions. Automatic gain modes take advantage the hardware’s advanced DSP technology. As a result, the sounder typically achieves a sharper image in any of the automatic gain modes than is possible in manual mode.

Chapter 5: Sonar Mode Operation 67

The DSM300 provides three pre-defined automatic gain settings:

AUTO

45%

CRUISING

GAIN

MANUAL

50%

CLR GAIN

CRUISING is the lowest automatic gain setting. It is ideal for viewing sonar image with a minimum of background noise as you are travelling to your fishing spot.

TROLLING is a slightly higher gain setting that displays more detailed echos as you search for targets.

FISHING is the highest automatic gain setting. It gives the best details of the targets you have located but also displays the m ost background noise and surface clutter.

Note:

The automatic gain modes are named so as to suggest when you might use them. However, it is not necessary for you to sel ect, for example, Fishing Mode only when you are fishing. You may want to take advantage of Fishing Mode’s higher gain even when cruising at high speeds. Your personal preference should determine which automatic gain mode you use, not necessarily your boat speed.

Color Gain

The COLOR GAIN determines how echoes of different strengths are displayed. Three shades of gray (monochrome display) or seven colors (color LCD) per palette are available and the echo strengths are divided into three (monochrome) or seven (color) bands to correspond with each shade of gray/color.

The color bar on the right hand side of the display, when set to ON in the Sonar Set Up menu (see Section 3.4), shows the colors being used, with strongest echo color at the top and the weakest echo color at the bottom.

The COLOR GAIN control sets the lower limit for the top color band: All echoes with a signal strength above this value are displayed in the strongest shade/color. All echoes weaker than this value are divided equally between the remaining shades/colors.

Setting a low value produces wide band for the weakest color, but a small signal band for the other colors; setting a high value gives a wide band for the strongest color, but a small signal band for the other colors.

Note:

On a color LCD, the sounder also provides a COLOR THRESHOLD control to reduce the number of colors displayed. Use COLOR THRESHOLD with COLOR GAIN to determine how echoes are displayed.

The DSM300 provides automatic or manual COLOR GAIN adjustment. Automatic adjustment displays colors based on current conditions, with as many colors as possible, while minimizing noise and clutter. As conditions change the auto-color gain adjusts. If you select manual adjustment, you will need to re-adjust the gain as conditions change.

68 DSM300 Operation with PLUS Series Displays

STC

GAIN

MANUAL

15%

STC

STC (Sensitivity Time Control) reduces surface clutter by reducing the gain in the top 100 ft of the display. This function is useful for reducing noise (caused by air bubbles and floating debris) that often appears in shallow water. A low STC value has little effect on gain in shallow water; a high STC value decreases the gain in shallow water so that only the strongest echoes are displayed.

Although you can manually set the STC level, Raymarine recommends letting the sounder module choose the proper level for you by selecting AUTO STC. Automatic STC mode takes advantage the hardware’s advanced DSP technology, which typically achieves a sharper image in auto mode than is possible in manual mode.

STC is not available in Sonar Simulator mode.

Using Alarms

ALARMS

The ALARMS key is used to set up alarms; three alarms are available to alert you of fish, shallow water, and deep water. Each alarm can be toggled ON and OFF and you set the depth at which shallow and deep water alarms are triggered: ranging from 2–3000 ft (or 2–4900 ft for high performance transducers).

You may want to use the shallow and deep water alarms when you are anchored. Set the limits to just above and below your anchor depth; the sounder triggers an alarm if the anchor drags and the boat moves into shallower or deeper water.

• Fish Alarm – If this alarm is ON the unit sounds a buzzer whenever it finds a fish. Different buzzer tones are used to indicate fish detected by the 50 kHz and 200 kHz frequencies.

• Shallow water – You set depth at which the shallow water alarm triggers. When the depth is less than that set, the buzzer sounds and a pop-up window describing the alarm is displayed. You cannot set the shallow alarm to be deeper than the deep alarm.

• Deep water – You set depth at which the deep water alarm triggers.When the depth is more than that set, the buzzer sounds and a pop-up window describing the alarm is displayed. You cannot set the deep alarm to be shallower than the shallow alarm.

Note:

The Deep Alarm must be set at a depth that is greater than the depth at which the Shallow Alarm is set. Conversely, the Shallow Alarm must be set at a depth that is less than the depth at which the Deep Alarm is set.

After you have acknowledged the sounding of a shallow or deep water alarm, a minimum of 30 seconds must elapse before a another shallow/deep alarm can sound again.

Chapter 5: Sonar Mode Operation 69

The top line status bar shows the condition of the alarms:

• indicates an alarm is enabled. The speaker symbol is unfilled until an alarm is triggered and silenced, then the symbol is shown solid.

• S indicates the shallow alarm is enabled; a pop-up window indicates when the alarm is triggered.

• D indicates the deep alarm is enabled; a pop-up window indicates when the alarm is triggered.

• indicates the fish alarm is enabled.

External Alarms

All SeaTalk system alarms (except autopilot, shallow, and deep) alarms are received and displayed in Sonar mode. You can silence these alarms by pressing any key. No other action is taken except to silence the alarm.

5.3 Using VRM

VRM/EBL

The VRM (variable range marker) key is used in Sonar mode to determine the depth and distance-behind-boat of an object on the display. The VRM function is available on the scrolling sonar display, bottom lock, and zoom windows.

A VRM is displayed as a cross hair with height and width of the display window. The center of the crosshair is the reference for which depth and distance-behindboat are displayed. You can use the context-sensitive cursor to move the VRM over a particular object.

Depth is displayed, in the system units, on the right hand edge of horizontal line. In the scrolling sonar and zoom windows depth is measured from the surface down. In the bottom lock window, depth is measure from the bottom up.

Distance-behind-boat is displayed next to the vertical line, at the top of the window. The VRM distance units correspond to the depth units assigned in the system set up parameters you have assigned for your display unit, as follows:

System Depth Unit VRM Distance Unit

Meters meters

Feet feet

Fathoms feet

The distance-from-boat continues to update as your boat moves.

However, the vertical line does not scroll with the scrolling sonar image. If the display range changes, the VRM adjusts its relative position so that it does not move out of the visible display area.

When you switch on the VRM, it is displayed at its last position (unless off screen, in which case it is displayed on-screen).

VRM/EBL

If the sounder is in split frequency display mode or a zoom window is displayed with the scrolling sonar image, then the VRM is shown in both windows at the same position. If bottom lock is displayed with the scrolling sonar image, the crosshair lines appear in bottom lock window but not in the scrolling sonar window.

➤ To switch the VRM on, or re-position an off-screen VRM:

1. Press VRM/EBL. The VRM is displayed in its last-used position.

Chapter 5: Sonar Mode Operation 71

The cursor is positioned at the center of the crosshair and has control of the VRM, as indicated by four-way arrow, the solid crosshair and the text VRM.

2. Use the trackpad to position the center of the crosshair over the desired object. The depth and distance-from-boat are updated as you move the cursor.

3. Press ENTER to drop the VRM. The crosshair is displayed as a dashed line.

➤ To move a VRM:

1. Move the cursor over the VRM you wish to change then press ENTER.

normally entered on a chart as a reference, or as a place to go to. This section provides details that are specific to placing Waypoints in Sonar mode.

You can only place a waypoint in Sonar mode if you have valid position data from

Note:

a GPS.

A waypoint can be placed at the cursor position or at the boat’s current position (this is sometimes known as an event mark); all waypoints placed on the sounder are stored in a waypoint database list with position, de pth and temperature when it was placed.

Waypoints placed on the sounder are displayed as a solid vertical line on the scrolling bottom, Zoom and Bottom Lock displays. The waypoint number is shown at the top of the vertical line. The waypoint scrolls to the left with the scrolling bottom display.

If you place a waypoint at the cursor position in Sonar mode and a chart window is open, the waypoint is displayed on the chart. You can GOTO, EDIT and ERASE a cursor waypoint.
