Preface
Purpose
Raymarine DSM300 Digital Sounder Modules provide echo sounder data that can
be displayed on Raymarine E Series, C Series, and hsb2 PLUS (Pathfinder) Series
display units. This handbook describes operating the DSM300 with hsb2 PLUS
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:
CAUTION: High Voltage
The DSM300 contains high voltages. Adjustments require specialized service
procedures and tools only available to qualified service technicians – there are no
user serviceable parts or adjustments. The operator should never remove the
cover or attempt to service the equipment.
CAUTION: Transducer Cable
Removing the transducer cable from the rear of the DSM300 while the sounder
module is powered on can cause sparks. Only remove the transducer cable after
power has been removed from the DSM300. As with any electronic device, be
sure the sounder module is mounted where it is well ventilated and free from
gasoline fumes.
If the transducer cable is accidentally removed while the DSM300 is powered on,
remove power from the sounder module, replace the transducer cable, and then
return power to the module. As a safety feature, the DSM300 only recognizes that
the transducer is connected at power-up.

2-
1
This handbook describes how to operate the DSM300 Digital Sounder Module
with hsb2 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 hsb2 PLUS (Pathfinder) Series display unit installed in your boat.
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 depends on your system configuration and set up options, 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 hsb2 PLUS (Pathfinder) Series display.
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.
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.

2.3 Selecting Sonar Mode
If properly connected to an hsb2 PLUS Series Radar, Chartplotter or Fishfinder
display unit, you can begin viewing echo sounder data by setting the display to
Sonar mode.
Note: Data, such as depth, speed, temperature, log, and trip are still available even if Sonar mode is not selected.

2.4 Selecting Repeater Mode
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 hsb2
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:
DISPLAY

DSM300 Operation with PLUS Series Displays
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.

with that unit.
Sonar Options
The DSM300 provides controls to select additional modes:
• Frequency – you can select the transducer frequency: 50 kHz for wide coverage 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.

2.7 Simulator Mode
The DSM300 includes a simulator function that enables you to practice operating
in Sonar Mode without data from the transducer.
Before using Simulator mode, make sure the display cable is connected from the
DSM300 to the display unit and that both the DSM300 and display unit are
connected to power.
If you have not fully installed the sonar module, you can still operate in Simulator
mode by connecting the DSM to the display device. Then connect the DSM300
and the display unit to a 10.7–32VDC power supply, attaching the red wire from
the power lead to positive (+) via a quick blow 8A fuse and the black wire to
negative (–).
Figure 2-5 demonstrates how to setup the DSM300 for Simulator mode.

Chapter 3: System Setup
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 the DSM300 Digital Sounder Module with a Raymarine
hsb2 PLUS (Pathfinder) Series display. Instructions for setting up the DSM300 with a C Series or E Series display are available in the handbooks for those products.
MENU
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.

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.
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) 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.
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.
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 instruments 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 and 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 available, 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.

Note: The DSM300 outputs the same depth value for DBT and DPT, regardless of the
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 options are switched on, each display shows 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 calibrate 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 hsb2 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 hsb2
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 hsb2 network).
Note: If you switch the PLUS Series fishfinder display from REPEATER to MASTER, you
must remove the DSM300 from the hsb2 network and power off & on the display unit for
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.
2. When the display is a PLUS Series fishfinder and you are using the DSM300,
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 hsb2 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.
Version/Serial Numbers
The area at the bottom of the Sonar Setup screen gives version information for the
system.
This area is informational only; it is not editable.
DISPLAY SW VERSION displays the software version of the display unit.
MASTER SW VERSION displays the software version and product type of the
master unit, which under most circumstances would be the DSM300.
MASTER S/N displays the serial number of the master unit, which under normal
circumstances would be the DSM300.
Chapter 4: Basic Display Controls

Chapter 4: Basic Display Controls
4.1 Introduction
This chapter will help you to become familiar with the functions of the hsb2 PLUS
Series display unit’s controls in Sonar mode. Information on operating Sonar
display mode is provided in Chapter 5. Instructions for operating the DSM300
with your C Series or E Series display are available in the handbooks for those
products.
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.
Simulator
The DSM300 includes a simulator function that enables you to practice operating
display controls in Sonar Mode without data from the transducer. Section 2.7
describes how to switch the display to simulator mode.
The DSM300 must be connected to an hsb2 PLUS Series, C Series or E Series display
unit to show echo sounder data.
4.2 Setting Color and Brightness
Brightness settings depend on the type of display you have. Monochrome
displays offer lighting and contrast settings, while color displays have brightness
and color settings.
Lighting and Contrast (Monochrome Displays)
You can change the level of backlighting and contrast for the screen and keys. The
key lighting is set the same as the screen lighting, except that it remains switched
on at its lowest level even when the screen lighting is turned off, so that you can
always find the keys.
➤ To change the lighting and contrast:
1. Press the MULTI key (or the MULTI knob on CRT radar units) to display the
soft key controls:

press and hold the trackpad to change the setting more rapidly. The lighting
level is adjusted as you change the setting.
5. Press the CONTRAST soft key. Adjust the setting in the same way as for the
lighting. There are 64 different contrast levels.
6. Press ENTER to return to the default screen, with the new lighting and contrast levels retained, or press CLEAR to discard the changes and return to the
default screen.
If lights are left ON when you switch off the display, the next time the display is
switched on, the lights will be ON, but at the default setting of 42%. The new
contrast level is retained until you reset it, unless you set the control very low or
very high; in this case, the contrast will be restored as follows:
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.

then use the trackpad to increase brightness. You can also press and hold MULTI for one
second to set the brightness to 100%.
Selecting the Background Color
Five colors are available for the sonar display background – black, dark gray, light
gray, white, and dark blue. The color you select is used on all the sounder windows
(scrolling bottom, Zoom, Bottom Lock, and A-Scope).
You will probably find that you need to change the background color in different
light conditions. For example, a white background is probably easiest to see in
bright sunlight, but a black background may be preferable at night.

• 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

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%

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).

image window is shifted up by the selected amount. Pressing the SHIFT keys
sets the range to MANUAL.
5. Press ENTER to return to the default display.
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:

1. Press the BTM. LOCK soft key. The Bottom Lock selection soft keys are displayed.
2. Press the BTM. LOCK OFF ON soft key to toggle the function ON.
3. Press the BTM. LOCK FULL SPLIT soft key to toggle between a full window
bottom lock image or split windows. The bottom lock image is displayed.
If you select split windows, the sounder display is split vertically, with the bottom lock image in the left hand window and the scrolling bottom display in
the right hand window.
In a split window display, a vertical bar appears (along the right hand edge of
the scrolling bottom image) that references the range being displayed in the
bottom lock window. This bar varies in height as the bottom lock range is
changed.
4. To adjust the range, press the appropriate BTM LOCK RANGE soft key: press
the up arrow to select a larger range, press the down arrow to select a smaller
range.

Chapter 5: Sonar Mode Operation
5.1 Introduction
Basic operation, including a description of the different 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 Raymarine hsb2 PLUS (Pathfinder) Series display. Instructions for operating the DSM300 with a C
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 the 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 line
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 LINE 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.

GAIN
MANUAL

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, weaker echoes (from air bubbles, for example)
are also displayed.
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:
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.
AUTO
TROLLING is a slightly higher gain setting that displays more detailed echos as
you search for targets.
45%
CRUISING
FISHING is the highest automatic gain setting. It gives the best details of the
targets you have located but also displays the most 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 select, 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
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.
MANUAL
50%
CLR GAIN
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

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

5.4 Waypoints
MARKS
The MARKS key lets you to place up to 998 waypoints. A waypoint is a position,
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.
Note: You can only place a waypoint in Sonar mode if you have valid position data from
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, depth 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.
72
