System overview
Key facts
The Simrad EQ60 echo sounders is designed for the
professional fishery community implementing the latest
innovations.
• The EQ60 system is flexible and easy to configure due to the
modular design.
• Echo sounders ranging from relatively low-cost single beam
to large multi-frequency systems can be realised.
• Menus and dialogue boxes are operated by a standard mouse
or a roller ball.
• Large colour liquid crystal displays (LCD) are used. A
standard computer mouse may be used.
• The EQ60 uses the Microsoft Windows® display interface.
Operation is to a large extent self-explanatory. Getting started
is easy if you are familiar with standard Microsoft
Windows® programs.
• A store/replay function reduces the need for echogram
printout on paper. The unprocessed transducer signal is
recorded on the internal harddisk. During replay, this signal
is injected into the EQ60 processing software as if it arrived
directly from the transceiver.
Main units
The standard version of the EQ60 echo sounder consists of the
following units:
• a display unit with built-in echo sounder transceiver and
processor units
• a transducer
If required, the system can be expanded with additional
frequency channels by adding single beam General Purpose
Transceiver (GPT) units.

System description
Wave propagation
The velocity of sound wave propagation in the sea varies
slightly with temperature, salinity and pressure. The velocity
varies between 1440 and 1520 m/s in shallow sea water, while a
velocity around 1480 m/s can be expected at 1000 m depth. In
shallow fresh water the velocity is approximately 1430 m/s.
A good average value to be used in the Environment dialogue
box is 1470 m/s.
Figure 1 The
wave propagation
principles
The EQ60 transmits high energy sound wave pulses into the sea.
A flat bottom reflects the transmitted wave as if it were a mirror.
The propagating energy is spread over a larger and larger area as
it travels down to the bottom and up again. The energy is spread
over a four times larger area every time the travel distance
doubles.
A large school of fish reflects sound waves similarly. This type
of spreading is referred to as square-law or 20 log TVG (Time
Varying Gain) spreading.
The situation is slightly different when observing the echoes
from individual fish. The transmitted wave undergoes
square-law spreading when travelling from the surface and
down to the fish. The swim bladder of the fish scatters a small
fraction of the arriving energy in all directions. Travelling from
the fish and back towards the surface the scattered wave
undergoes another square-law spreading. The combined effect is
referred to as quad-law or 40 log TVG spreading.

Simrad EQ60
Propagation losses due to absorption are much higher in sea
water than in fresh water. Absorption also increases with
frequency. At 38 kHz the absorption is 0.5 dB/km in fresh water
and 10 dB/km in sea water. At 200 kHz the absorption is 10
dB/km in fresh water and 50 dB/km in salt water. The echo
sounder must know which water type is present in order to
compensate for these losses correctly.
(The dB (decibel) unit has long traditions in underwater
acoustics and other fields in physics. It is a logarithmic measure
for the ratio between two quantities).

System description
Bottom echo
A hard flat bottom reflects the transmitted signal as if it were a
mirror. The transmitted pulse hits the illuminated bottom area at
nearly the same instant, and the echo from different parts of this
area arrive back at the surface also at nearly the same instant.
Figure 2
Bottom echo
The received echo signal is basically an attenuated copy of the
short transmit pulse. The echo signal from a sloped bottom is
characterised by having a longer duration and a slower rise and
fall time. The transmitted pulse first hits the slope at point A,
and as time elapses the reflection point travels along the slope
towards point B. Many locations do not have a solid hard
bottom. Frequently, the bottom is composed of layers of mud,
clay and sand which can be observed as coloured bands on the
echo sounder display.
The bottom detection algorithm is implemented solely in
software, and separate algorithms are run for each frequency
channel. The algorithm is designed with emphasis on reliability
in the sense that erroneous depth detections are never output.
Whenever the quality of a detection is questionable the
algorithm outputs a depth of 0.00 to indicate that no reliable
detection was obtained. The EQ60 algorithm is designed to
handle a number of difficult situations. The algorithm maintains
bottom lock for a discontinuous jump in bottom depth. It avoids
false bottom detections on a dense school of fish. The algorithm
chooses the upper boundary of the first layer when the bottom
consists of layers.

Simrad EQ60
The bottom detection algorithm locks to the first good bottom
return. The depth at point A rather than the depth along the
transducer axis will be output for a sloped bottom. The detected
depth value is always smaller than the depth along the
transducer axis implying that a safety margin is automatically
included.

System description
Observation range
Absorption increases dramatically with frequency in salt water.
For maximum observation range you should select a low
operating frequency, a large transducer and the maximum
transmit power.
Figure 3 Observation range
Typical observation ranges are shown in the figure. Using the
Simrad 27-26/21 transducer (27 kHz, 10x13 degrees, 3000 W)
you can observe a 60 centimeter cod down to 800 meters, and
bottom detection works down to 3800 meters. However, with
the Simrad 200-7F transducer (200 kHz, 7x7 degrees, 1000 W)
you can only observe that same cod down to 260 meters, and
bottom detection becomes unreliable below 500 meters.
These range calculations assume a normal sea water salinity
(3.5%) and temperature (+10 degC), an average bottom (surface
backscattering strength = -20 dB) and a noise level typical for a
moving vessel.

Echo frames
Overview
The EQ60 Echo frames are the main information bearer on the
echo sounder display. The Echo frames are usually presented in
pairs with two echo frames for each channel.
The Echo frame contains the following views:
(A) Echogram and Range view
(B) Scope view
B
(CD10207)
A
Echogram and Range
The Echogram and Range view consists of an Echogram field
to the left and a Range field to the right. These are separated by
the vertical range axis. The Echogram field contains
information about the acoustical values, while the Range field is
used for specifying the range used in the Echogram field. The
settings in the Colour Scale is used to present the information.
When you place the cursor in the Echogram field, you can use
the mouse wheel to modify the gain setting, and hence the
display colour sensitivity. Each click of the wheel corresponds
to a 1 dB change. The same gain setting is available from the
Colour Scale dialogue box.
857-164342 / Rev.C
21
Simrad EQ60
Whenever the cursor is located within the Echogram field, a
small yellow label is visible. The label provides the following
information:
• Left: Depth at the cursor position
• Middle: Diameter coverage from the transducer beam
• Right: Current gain setting
To change the range, you can also use the mouse wheel. Place
the cursor inside the Range field to do this:
• In a surface related echogram you will modify the range,
while for a bottom related echogram, you will change the
start range.
• If you press the left mouse button while you use the mouse
wheel, the surface echogram will change its start value, while
the bottom related echogram will change its range.

Scope
The Scope view is the rightmost view and shows a oscilloscope
view of the last ping corresponding to the settings in the
Echogram view.
This view draws a range of horizontal symmetrical colour lines.
The distance from the vertical centre axis and the line colour
reflects the received echo amplitude. A black horizontal line
across the view indicates the current bottom view.
If you press the right mouse button with the mouse pointer
positioned in the Scope view, the graphic presentation will be
replaced by a text based presentation of the data. The following
information is provided:
Channel:
Background Noise: yyy.y dBW
Receiver Amplitude: xxx.x dBW
Alongship angle: z.zz deg
Athwarthship Angle: z.zz deg
The background noise shown is the median of 20 equidistance
power samples in the total range of the current ping. The
receiver and the two angles (alongship and athwarthship) are
sampled at 100 m depth. During replay, you may find that this
depth setting is not availbale because the depth is less than 100
m. The receiver amplitude is then set to a minimum (235 dBW),
and the angles are set to zero.

History and printer views
Overview
The echogram information provided on the display will differ
slightly from the information provided on the printer and in the
History files. This is because the annotation settings differ
between the two media.
The annotations provided for display output are controlled by
the Annotations dialogue box. When enabled in the Prister
and History dialogue box, the annotations will also be sent to
the printer and to the History files.
The Printer and History dialogue box also enables additional
annotations to be printed.
The most important difference is that the annotations added to
the echogram will only show in full on the printer and in the
History dialogue box. To demonstrate this difference, refer to
the two illustrations.

Start-up
Overview
This chapter provides the basic procedure required to power up
the echo sounder and start the pinging.
Power-up procedure
After these initial preparations you can open the EQ60 program
on the computer. The “power on” procedure is described in
detail in the Operational procedures chapter.
The menu system
The menu system is based on the Microsoft Windows®
commercial standard interface. An overall explanation of the
menu system with a description of the various views are
presented in the Display views chapter.
Transceiver inspection
First, we need to check that the transceiver (or transceivers) are
connected.
Open the Install menu, choose the Transceiver command to
open the Transceiver Installation Mode dialogue box. In this
dialogue, press the Inspect button to open the Transceiver
Settings dialogue box.
You may now check that the transceivers are installed correctly.
Active transceivers appear in green text in the Frequency
Channel Selection box.
Click the Cancel button to finish.
If none of the transceivers listed appear in green text, check the
connections and re-install the transceiver(s).
Environmental parameters
To obtain correct values for the various acoustical parameters
calculated by the EQ60 program, it is important that you provide
the EQ60 program with accurate parameters describing the
environment; sea temperature, salinity and sound velocity.
These values are defined in the Environment dialogue box.
Open the Install menu, choose the Environment command to
open the Environment dialogue box.
Unless the default values are acceptable, you must select Fresh
or Salt water, and enter the current sound velocity. This
information is used to calculate depth and absorption
coefficient.
Click OK when you have finished.

857-164342 / Rev.C
Getting started
Navigation interface
To link acoustical data with navigational data the EQ60 must be
able to receive data provided by a GPS or another positioning
system. The Navigation Interface dialogue box is used to
define the parameters to achieve this.
Open the Install menu, choose the Navigation command to
open the Navigation Interface dialogue box.
Specify how the EQ60 will receive navigational data. Since the
NMEA standard has been implemented, you only need to
choose between NMEA or ASCII.
Click OK when you have made the setting.
Additional interfaces
Additional interfaces have been provided for other peripheral
systems.
• If you need to link recorded acoustical data with trawl
position data, choose the Trawl command on the Install
menu to specify the trawl position interface.
• If you need to connect your EQ60 to a purse seine system,
choose the Purse seine command on the Install menu to

Operation
Overview
This chapter describes a few of the most common functions used
during normal operation.
Selecting operational mode
You are now ready to start the actual operation of the EQ60
echo sounder. The first thing to do is to choose operational
mode.
Open the File menu, choose Operation to open the Operation
dialogue box. In the Mode group, click Normal for normal
mode.
(You may alternatively click Replay for replay mode, but you
must then also click Files to choose a replay file. Note that
operating in replay mode will restrict you from changing certain
parameters during operation.)
Next, you need to define the ping rate. To do this, locate the
Ping Rate group box, and set the ping rate to Interval for
manual setting of the ping interval. For this exercise, set the
ping interval time to 1 second, and click OK to finish.
The echo sounder will now start pinging, and after a few
moments the echogram field on the display will present a new
echo line. The various fields on the display are explained in
detail in the Display views chapter.
Transceiver settings
The operational mode and the transceiver frequency are
displayed to the far left in the Header view. A dedicated
dialogue box - Transceiver Settings - is used to define various
parameters associated with the transceiver. These settings
include transceiver mode, the depth of the transducer surface,
the transmit power, and the pulse length.
Note that if you operate in Replay mode, the transceiver settings
can not be changed.
Additional information about the transceiver settings are
available if you press the Advanced button in the Transceiver
Settings dialogue box.
32
857-164342 / Rev.C
Getting started
Bottom detector settings
The Header view on the display is also used to present the
current depth. The Bottom Detector dialogue box is used to
define various parameters associated with the bottom detection.
These include the depth range, where the EQ60 searches for the
bottom.
To open the Bottom Detector dialogue box, position the cursor
over the displayed depth in the Header view, and click the right
mouse button.
In our example we will assume that the depth will vary between
30 and 200 meters. Therefore, set Minimum Depth to 30 m and
Maximum Depth to 200 m. Click OK to accept the settings.
Note
Setting both Minimum Depth and Maximum Depth to 0 m will
turn off bottom detection.
Colour scale
The Colour Scale field is used to display the colour scale for
mapping acoustical values. These colours are used in the
Echogram And Range view. Each colour always represents a
3 dB value range. Using all 12 colours in the colour scale thus
enables mapping of a 36 dB value range to colours.
Position the cursor over the colour scale, click the right mouse
button to open the Colour Scale dialogue box. Accept the
default settings and click OK.
Echogram and Range view
The Echogram and Range view consists of an Echogram field
to the left and a Range field to the right. These are separated by
the range axis. The Echogram field contains information about
the acoustical values, while the Range field is used for
specifying the range used in the Echogram field.
Echogram field
The Echogram field is used to display acoustical values for
each ping. The settings in the Colour Scale are used to
determine the colour sensitivity in the echogram.
Position the cursor in the Echogram field, and click the right
mouse button to open the Echogram dialogue box.
857-164342 / Rev.C
33
Simrad EQ60
The Echogram dialogue box allows you to define the area of
interest for the echogram. Your choice will affect the meaning
and the options in the Range field in the Echogram view. You
can also choose the TVG function used to calculate the
acoustical values.
In this example, choose Surface – Manual to enable a surface
related echogram. Then, choose the School gain TVG function
for calculating sV-values. Finally, click OK to accept the
settings.
Range field
The Range field allows you to read and specify the range used
in the Echogram field. The current range is displayed on the
range axis. In the Range dialogue box you can define the area of
interest for the echogram.
Position the cursor in the Range field, click the right mouse
button. Observe a dialogue box referring to either Surface,
Bottom, or Trawl depending on your choice in the Echogram
dialogue box.
In this case, check that you have the Surface Range dialogue
open.
Set Range to 200 m and Start Relative Surface to 0 m, then
click OK to accept the settings.
Comments to the Echogram and Range view
Two echograms are shown for each Channel. The second
echogram for the present Channel may be used in the current
example to show the distribution of fish close to the bottom.
• Use the Echogram dialogue in the second Echogram view
to set the Echogram to Bottom and choose the School gain
TVG function for calculating SV-values.
• Use the corresponding Bottom Range dialogue to set Range
to 20 m and Stop Relative Bottom to 5 m for the echogram
to show values calculated from 15 m above the detected
bottom to 5 m below the bottom.
When you place the cursor in the Echogram field, you can use
the mouse wheel to modify the receiver gain level, and hence
the display colour sensitivity. Each click of the wheel
corresponds to a 1 dB change. The same colour sensitivity
setting is available from the Color Scale dialogue box.
Whenever the cursor is located within the Echogram field, a
small yellow label is visible. The label provides the following
information:
34
857-164342 / Rev.C
Getting started
• Left: Depth at the cursor position
• Middle: Diameter coverage at the transducer beam at the
current cursor position
• Right: Current gain setting
To change the range, you can also use the mouse wheel. Place
the cursor inside the Range field to do this:
• In a surface related echogram you will modify the range,
while for a bottom related echogram, you will change the
start range.
• If you press the left mouse button while using the mouse
wheel, the surface echogram will change its start value, while
the bottom related echogram will change its range.
Scope view
The Scope view is the rightmost view and shows a scope view
of the last ping corresponding to the settings in the Echogram
view.
This view draws a range of horizontal symmetrical colour lines.
The distance from the vertical center axis and the line colour
reflects the received echo amplitude. A black horizontal line
across the view indicates the current bottom view.

Data storage
Overview
This chapter presents a brief description of the data storage
functionality.
Note that you can not perform all the operations described here
if your echo sounder does not have a keyboard.
Define storage parameters
It will often be beneficial to store some of the echo information
recorded during an operation. This allows you to change certain
parameter settings when operating in replay mode at a later
time.
Open the File menu, choose Store to open the Store dialogue
box.
Note that Store is not available when operating in Replay mode.
The Store dialogue box allows you to set various parameters
associated with data storage. You can define a specific directory,
and limit the file sizes.
Click Browse in the Survey box. Browse to the desired
directory for file storage, or enter the directory name directly
into the text box. If the directory does not exists it will be
created.
Click the Save Raw Data check box to save raw data. Define
maximum file sizes by entering the desired value in the Max
File Size box, and click OK to accept the settings.
When Save Raw Data is checked, the raw unprocessed
transceiver data containing amplitude and angle information for
the split beam transducers will be recorded.
Start and stop data storage
To start and stop data storing, use the Line field in the Status
bar. The Line field is marked LXXXX and shows the current
survey line number.
Position the cursor over the Line field in the Status bar and
click the left mouse button. Observe that the survey line number
increments, and that the line colour changes from black to red.
To stop data recording click the Line field again.
The red colour indicates that data recording is active. When the
recording stops, the colour is changed back to black. The file
names used for the stored data are determined by the survey line
number and the date and time when recording started. A new
file is created for each new survey line number.

Record and playback
Overview
You can set up the echo sounder to record the unprocessed
transducer signals on the internal harddisk or other recordable
media. This recorded signal may later be injected into the echo
sounder’s processing software as if it arrived directly from the
transceiver.
During this replay, you may experiment with some of the echo
sounder settings.
This feature is useful during training and demonstration. It is
also useful for memorising a particularly interesting observation
at the fishing grounds.
You can also use the built-in History function to record
echogram data.
Record
Preparations
The recording is prepared as follows.
4
Select Store on the File menu.
- Observe the Store dialogue box appear.
Select the complete path of the survey directory.
- The directory is selected when you click the OK
button. Click the Browse button if you wish to navigate
through the disk directories. A new directory is created
if the requested does not exist.
Select if you wish to save raw and/or output data.
- Raw data: The unprocessed transceiver data are stored
in standard computer files. These files contain all the
necessary data for reconstruction of the situation during
the real survey. Thus the data include amplitude, phase,
navigation data, annotation input etc. The echo sounder
program reads these files during replay.
- Output data: This is the processed output data;
navigational data, bottom detections, annotations etc
Select the initial line number.

Stop recording
To stop the recording:
1
Click the Line field once again.
- The original colour is restored.
Size of stored raw data
The total size of raw data files stored on disk during operation
depends on several user selections. From these selections you
may estimate approximately the total amount of raw data stored
in a given time period for each installed channel using the
following equation:
X = (B bytes per sample) S ((8 S R) / (c S tau samples per ping))
S (M ping per sec) S 24 S (3600 sec per day) S (K days)
Where:
X = Total amount of stored raw data in bytes for one channel
B = 4 (Given by the echo sounder)
R = Maximum range in meters (User set)
c = Sound speed in water in meters per sec (User set)
tau = Pulse duration in seconds (User set)
M = Ping rate in ping per seconds (User set)
K = Number of operating/storage days (User set)
Thus, you can affect the amount of stored raw data by changing
e.g. the range, pulse duration, and ping rate settings.
Example:
With range = 10 m, pulse length = 256 µS, 15 pings per second
and sound velocity = 1500 m/s, the storage requirement will be
45 Mb per hour. If you increase the range to 80 m, and reduce
the ping rate to 7 pings per second, the storage requirement will
be 60 Mb per hour.

When replaying the recorded signal, the ping rate is not limited
by the speed of sound in water. Hence, a higher ping rate is
possible during replay than during normal operation.

History
The History function is used to store echograms on bitmap
format. The echo sounder may continuously save echogram
pictures to the internal harddisk or an other recordable media.
These can later be recalled on the display. The information in
the History window is the same as on the printer.
The horizontal width of each echogram picture roughly
corresponds to the the half width of the display. The number of
history files is limited. After reaching the maximum number of
files, the newest echogram picture overwrites the oldest one.
The history function allows you to quickly look through
echogram pictures covering several hours.

Software installation and upgrades
Overview
The echo sounder is initially delivered with all necessary
software installed and configured. Software upgrades are useful
if your echo sounder fails, and you suspect a software error. An
upgrade is also required whenever the echo sounder software is
modified.
The computer should automatically detect the insertion of the
CD-ROM and open the Installation program dialogue box. If
this is not the case, you must manually run the Setup.exe
program on the CD-ROM’s root directory.
When the echo sounder software is upgraded, the software will
automatically detect the presence of General Purpose
Transceiver(s), but you will need to check that the correct
transducer(s) are enabled.
Whenever new echo sounder software is installed, you will need
to define all serial lines, transducer(s) and transceiver(s).

Advanced Transceiver
This dialogue box is accessed from the Transceiver Settings
dialogue box. It displays detailed numeric information
characterising the channel. This includes transducer parameters,
exact transmit frequency and receiver processing parameters.
Parameters
The parameters shown in this dialogue box are determined
during the transceiver installation procedure.
The descriptions are included for information only. You do not
need to understand these parameters to operate the echo sounder.
Frequency [Hz] - This is the nominal resonant frequency for
the transducer.
Beam type - Three different transducer beam types are
available: Single, Split and Triple. If your system is capable of
operating a Split- or Triple beam transducer, it will also be able
to measure the position of a target in the beam. The echo
sounder can then compensate for the known beam pattern to
obtain a true target strength.
Gain [dB] - The transducer gain presented by calculating the
directivity multiplied with the transducer’s efficiency. The value
is obtained during system calibration. If no calibration takes
place, the manufacturer’s default setting is used.
Two-way beam angle [dB] - This is a key transducer
parameter. The value describes the solid angle at the apex of the
ideal conical beam.
Sa Correction [dB] - This parameter is determined during the
calibration process. The value represents the correction required
to the Sv constant to harmonize the TS and sA measurements.
68
857-164342 / Rev.C
Instruction manual
Absorption [dB/km] - This value describes the absorption of
sound in the water. The default values are computed according
to Francois and Garrison, Journal of Acoustic Society,
December 1982. The most important environmental variable
affecting this parameter is found in the Environment dialogue
box.
Bandwidth [Hz] - This is the resulting system bandwidth of the
analogue and digital filters in the echo sounder receiver. The
bandwidth is a function of the selected pulselength at a given
frequency.
Sound velocity [m/s] - The speed of the sound through the
water varies with temperature, salinity and pressure. The
soundings provided by the EQ60 are compensated for this.
Sample interval [m] - This value is always 1/4 of the current
pulse length. In distance, the sample interval will be expressed
as (sound velocity multiplied with pulse length) divided by
eight.
Angle sensitivity - In order to convert the raw angle samples
into mechanical degrees for fore-and-aft and athwartship
directions, this parameter is required. It represents the ratio of
electrical degrees to mechanical degrees for the current
transducer. This ratio is not used with single beam transducers,
and the value is set to 0.
3dB beam width [degrees] - This value presents the 3 dB
beamwidth of the current transducer in the fore-and-aft and
athwartship directions. The value is estimated during
calibration. If no calibration takes place, the default value is

The EQ60 echo sounder supports these different types of
annotation:
• Text - use this function to enter your own text.
• Time - use this annotation to automatically generate a time
marker at specified intervals.
• Event - use this annotation to generate an event number with
optional addition of time and/or navigation.
• External - this function allows automatic annotation from an
external source.
Note that the Text annotation is only available if you have a
keyboard connected to the echo sounder.
An annotation telegram is written into the replay data file and
the output data file. The annotation message is only shown
inside the history window and on the echogram printout.

Text
The annotation text is entered here. Note that you need to have a
keyboard connected to the echo sounder. The text can be entered
freely, for example ”Dangerous wreck”. When you press the
OK button the text is written into the echogram. The next time
you open the Annotation dialogue box, the text is cleared, and
you must enter new information.
Time
Click Active to activate automatic time annotation. Enter the
desired time interval between the annotations. When activated,
the sounder automatically generates annotations containing the
current time at the chosen interval.
Event
Each event annotation is identified with an individual event
number. The event annotation is then generated every time an
event is generated. The event number is initially chosen here,
and thereafter automatically incremented or decremented every
time a new event is generated.
To generate an event, click Event in the Status bar.
The Event annotation can include current time and/or current
longitude and latitude. Click applicable Add Time or Add
Navigation to select. Without time or position data selected, the
annotation message will simply contain the event number.
External events
External annotations may be input via the serial port for
navigation as an NMEA telegram. The Annotation dialogue
box does not support direct control of this function.
The external annotation has the following format:
$??ATS,this is a test<CR><LF>
The telegram header consists of:
857-164342 / Rev.C
1
the $ character
2
two letters ?? (disregarded by the echo sounder, identifies
the sender of the telegram)
3
three letters ATS (Annotation Text String - identifies the
type of NMEA telegram).
4
a comma (NMEA separation character).
5
Text string (The echo sounder handles the string as an
ordinary text. You can not use commas in the text string.)
71

Bottom Detector
The Bottom Detector dialogue box is opened when you
right-click on the numeric depth value in the Header view on
the display.
This dialogue box is used to define the upper and lower depth
limits most likely to be used during the echo sounder operation.
These limits may be used to obtain ”bottom lock” on the depth
when the echo sounder is pinging. The sounder needs this lock
to locate the correct depth, and to stay on it during the
operation, even though the depth changes continuously.
The dialogue box is also used to set alarms to notify you if
maximum or minimum depths are exceeded.
Parameters
Minimum Depth - The bottom detector starts the search for the
bottom echo at this depth. The detector will fail in shallow
water if you select a too large depth value, and the tail of the
transmitting pulse may cause problems if a too small value is
set.
857-164342 / Rev.C
75
Simrad EQ60
Maximum Depth - The search for the bottom echo extends
down to this depth whenever bottom track is lost. Enter a
slightly larger depth value than the deepest spot you expect to
visit in order to avoid annoyingly long ping intervals every time
bottom track is lost. A depth value of either 0 or less than the
minimum depth disables the bottom detector.
Bottom Lost Warning - A warning is activated whenever
bottom track is lost. The warning is presented as a message in
the Status bar and as an audio signal.
Min. Depth Alarm - An alarm is activated whenever the
detected bottom depth is smaller than the chosen alarm
threshold. The warning is presented as a pop-up message and as
an audio signal. When the depth value is set to 0, this function is
disabled.
Max. Depth Alarm - An alarm is activated whenever the
detected bottom depth exceeds the alarm threshold The warning
is presented as a message on the display and as an audio signal.
When the depth value is set to 0, this function is disabled.
Backstep Min. Level - After the estimated depth of the bottom
detector, the detected depth is automatically adjusted by
stepping back according to the value of the setting you have
chosen. This allows the EQ60 to verify that the correct bottom
depth has been located. If the value you enter is too large (close
to 0 dB) the adjustments will be very small.
The default value is -50 dB.
Bottom Smoothing - If bottom track is lost, the detected
bottom depth is repeated for a maximum of three consecutive
pings.
Alternative Bottom Detector - This bottom detector resembles
the Simrad ES 380 bottom detector algorithm. This function
may be useful in a steep bottom slope situation.

Bottom Range
The Bottom Range dialogue box opens if you click the right
mouse button in the range field in the Echogram and Range
view while operating with a Bottom Range echogram.
The different echograms are explained in the Echogram
dialogue box.
Range - This parameter controls the vertical depth range across
the echogram.
Stop Relative Bottom - This parameter controls the depth offset
at the lower boundary of the echogram relative to the detected
bottom; positive values downwards.
Note that you can also change the range using the mouse wheel.

Colour Scale
The Colour Scale dialogue box is opened when you right-click
on the colour scale in the Header view.
This dialogue controls the mapping of echo strength into one out
of 12 colours, light blue for weak signals and dark brown for
strong signals. Each discrete colour represents a 3 dB range of
echo signal strength implying that the next colour is selected
every time the echo strength doubles.
Parameters
A high numeric value displays weak echo signals properly while
the stronger signals saturate into dark brown colour. A low
numeric value displays strong echo signals properly. Weak
signals below the lower limit of the colour scale are not
displayed (the display background colour is used).
School Gain - This parameter controls the display sensitivity of
the echo sounder down to the detected bottom depth when
School Gain is selected in the Echogram dialogue box. A
numeric value of 70 sets the lower limit of the echogram colour
scale equal to a volume backscattering strength of -70 dB.
Fish Gain - This parameter controls the display sensitivity of
the echo sounder down to the detected bottom depth when Fish
Gain is selected in the Echogram dialogue box. A numeric
value of 50 sets the lower limit of the echogram colour scale
equal to a target strength of -50 dB.
78
857-164342 / Rev.C
Instruction manual
Limit gain regulation - Due to the high dynamic range in the
EQ60 echo sounder, invidious gain settings may result in
unwanted noise. This will also cause the fish size estimates to be
erroneous. This gain regulation setting will limit the receiver
gain to maximum 100 dB. The limitation will prevent the echo
sounder from saturation.
Bottom Gain - This parameter controls the display sensitivity
of the echo sounder below the detected bottom depth. A
numeric value of 70 sets the lower limit of the echogram colour
scale equal to a surface backscattering strength of -70 dB.
No TVG - This parameter controls the display sensitivity of the
echo sounder when No TVG is selected in the Echogram
dialogue box. A numeric value of 70 sets the lower limit of the
echogram colour scale equal to a measured input level of -70
dB.
Removing colours
By left-clicking on the colours in the colour rectangle in the
upper right-hand corner of the screen, the selected colour will
become the weakest colour shown in the Echogram and Single
Echo views.
To restore the colour range, click on the removed colour’s
position.
Note that this is a display function only. It does not have any
effect on the sounder’s performance. It will however affect the
recordings made by the History function.

Depth Output
The Depth Output dialogue box is called from the Heave
Sensor, Trawl Interface and Navigation Interface dialogue
boxes. These are in turn accessed from the Install menu.
It allows you to control the depth data output.
Parameters
Depth output - Check to enable the depth output.
Checksum - A checksum may optionally be appended to the
NMEA output telegrams (according to the NMEA standard).
Channel - NMEA depth telegrams are only output from one
channel at a time. Select channel from the list of installed
frequency channels.
The GPT uses its Ethernet address for unique identification, and
the PCT uses its ISA bus parameters; IO address, DMA channel
and IRQ number. The channel number identifies individual
channels within a multi-channel transceiver.
Telegram - The echo sounder can output three different types of
NMEA depth telegrams. However, only one telegram type at a
time can be generated. You can select the telegram type here.
• The $SDDBS telegram contains the depth below the surface.
• The $SDDBT telegram contains the depth below the
transducer.
• The $SDDPT telegram contains the depth below the
transducer and the distance between the transducer and the
waterline.
The EQ60 can also output the EA 500/EK500 compatible depth
telegrams; D1, D2 etc. Output for Atlas echo sounders are also
provided.

Simrad EQ60
Surface - Auto Start - The echogram is related to the sea
surface. Vertical range is manually selected in the Surface
Range dialogue box. The EQ60 performs automatic adjustment
of the start depth keeping the bottom echo inside the visible
echogram.
Bottom - The echogram is related to the detected bottom. Stop
depth (lower echogram boundary) and vertical range are
manually selected in the Bottom Range dialogue box. The
echogram is only drawn for pings having a successful bottom
detection.
Trawl - Trawl sensor systems communicate headrope depth and
headrope-to-footrope distance to the EQ60 at regular intervals.
The echogram covers the vertical opening of the trawl including
a small margin at each side. The headrope and footrope margins
are identical. Their size is selected in the Trawl Range dialogue
box. The headrope-to-footrope distance can be manually set in
the Trawl Interface dialogue box for trawl sensor systems not
measuring the trawl opening, or when the measured
headrope-to-footrope distance is unreliable. The echogram is
only drawn when trawl position information is available.
Horizontal Depth Lines
Scale - Equidistant horizontal scale lines are drawn inside the
echogram in the current foreground colour; black during day
and white during night. A maximum of 50 scale lines can be
drawn. No scale lines are drawn when the scale line count is set
to zero.
Bottom:
• On - The detected bottom depth is shown as a thin line in the
echogram. The line is drawn in the current foreground
colour; black during day and white during night.
• Off - The bottom line is switched off.
• White Line - A band in the current background colour is
drawn below the detected bottom depth.
Variable Depth - When enabled a horizontal depth line is
placed wherever you click in the Echogram view. The depth of
the line is displayed at the left end of it. In the History diagram
the depth for each ping is displayed individually.
Trawl - Headrope and footrope depth are indicated by two red
lines in the echogram. Continuous lines are drawn when the
current depth values are available, and dotted lines are drawn
for a period of two minutes when this information is not
available. No lines are drawn after two minutes.
82
857-164342 / Rev.C
Instruction manual
Range other - Two horizontal lines indicate the range presented
in the lower echo frame.
Purse Seine - The depth of the purse seine sensor is indicated.
Vertical Markers
Event - A vertical line is drawn when a new event is generated.
Minute - A short vertical line is drawn in the upper part of the
echogram once every minute.
New Range - A vertical line is drawn when the range is
changed. The old range is written on the screen as an
annotation.
Gain
No - No TVG is applied. The echogram displays the input
power level at the transducer terminals. This echogram type is
used for special purposes when TVG is not applicable or
required..
School - The echogram displays volume backscattering strength
above the detected bottom, and surface backscattering strength
below the detected bottom. Volume backscattering strength is
suitable when observing a school of fish, and surface
backscattering strength is suitable when studying the properties
of the bottom.
Fish - The echogram displays target strength above the detected
bottom and surface backscattering strength below the detected
bottom. Target strength is suitable when observing individual
fish, and surface backscattering strength is suitable when
studying the properties of the bottom.
RCG (Reverberation Controlled Gain)
Apply this filter to enhance the detection of single fish on a
background of reverberation or noise.
Ping Filter
The ping-to-ping filter ”cleans up” the echogram by removing
random noise spikes with no correlation with the previous ping.
The function will thus make echoes appear more stable.
The ping filtering effect may be varied using the three different
settings provided, or it may be switched off.
Weak - Only two pings are correlated
Medium - Four pings are correlated
Strong - Eight pings are correlated.

Instruction manual
Environment
The Environment dialogue box is available from the Install
menu.
Many other echo sounders are calibrated to a sound velocity of
1500 m/s. If the EQ60 is used together with other sounders it is
advantageous to adjust the sound velocity on the EQ60 as well,
in order to have the same depth readings.
Salt Water / Fresh Water - Propagation losses due to
absorption are much higher in sea water than in fresh water.
Correct compensation for these losses therefore relies on the
echo sounder knowing which water type is present.
Sound Velocity - For accurate measurement of bottom depth the
correct sound velocity must be entered. Normally, 1470 m/s is a
good average value.

History
The History dialogue box is accessed from the View menu.
It displays echogram views previously saved during normal
echo sounder operation. This function greatly reduces the need
for echogram printout on paper. The presentation is made in a
separate window, and the echo sounder operates normally in the
background.
Note that the number of history files is limited to 400 in the
same directory.
Echograms covering the past hours can be viewed by operating
the scroll bar at the bottom of the dialogue; the oldest echogram
view to the left, the newest echogram view to the right.
Click the button in the lower right corner if you wish to print the
current view. If you wish to print a series of echograms click the
button with the + sign.
The echograms stored in the history files are available on

IP Address
The IP Address dialogue box is used when you need to change
the echo sounder’s addressing.
Note that this operation is not required on a daily basis. You
only need to modify the address if your echo sounder system
shall be connected to an existing computer network on the
vessel. As long as the EQ60 operates as a stand-alone system
using the hardware supplied by Simrad, you will not need to
change anything.
To access this dialogue box, open the Transceiver Installation
dialogue box from the Install menu, select a transceiver, and
click Set new GPT IP Address. The echo sounder will stop
automatically.
If you need to change the address, keep 157 and 237 as the two
first bytes, as these are common for all Simrad equipment. The
two remaining digits can be chosen freely, provided that no
other Simrad equipment with the same address is connected to
the same network. Thus, if you operate with more than one
GPT, these must be set up with different IP addresses.
Background theory
IP addresses are shown as four decimal integer numbers, where
each integer number corresponds to eight bits (or one byte) of
the address.
An IP address consists of a network address and a host address.
Three address classes are defined:
Class A used on large networks:
0NNNNNNN HHHHHHHH HHHHHHHH HHHHHHHH
Class B used on medium size networks:
10NNNNNN NNNNNNNN HHHHHHHH HHHHHHHH
Class C used on small networks:
11NNNNNN NNNNNNNN NNNNNNNN HHHHHHHH
857-164342 / Rev.C
91
Simrad EQ60
The address class is determined from the high-order bits of the
first byte.
• The first byte of a Class A address contains a zero and seven
network bits. The next 24 bites identify the host.
• A Class B address contains a one, a zero, 14 network bits and
16 host bits.
• Finally, a Class C address contains a one, a one, 22 network
bits and 8 host bits.
The echo sounder computer, GPT transceiver(s) and other
computers that communicate on the ethernet must reside on the
same network. This requirement is met only if the host part of
the address differs.

Operation
The Operation dialogue box is accessed from the File menu.
This is the main dialogue box for operational control. You can
select operational mode and ping rate, and you can initiate
recording of the echo sounder information. The sounder has two
functions to greatly reduce the need for echogram printout
paper: Store/Replay and History.
The Store/Replay function records the unprocessed transceiver
data on the internal harddisk. These data are later injected into
the echo sounder processing software as if it arrived directly
from the transducer. When replaying the recorded signal, you
are free to experiment with the echo sounder settings.
This feature is useful during training and demonstration. It is
also useful for memorising a particularly interesting observation
out at the fishing grounds.
The Store dialogue box is available from the File menu. The
Replay dialogue box is available from this dialogue box when
you click on the Files button.
857-164342 / Rev.C
97
Simrad EQ60
The History function is equivalent to the print function. The
echo sounder continuously saves echogram ”printouts” or
echogram pictures to the internal harddisk. These can later can
be recalled on the display.
The horizontal width of each echogram picture roughly
corresponds to the width of the display. History memory is
organised as a circular loop; the newest echogram picture
overwrites the oldest one. The circular memory holds several
hours of echogram recording. The history function allows you
to quickly look through echogram pictures covering the past
hours.
Mode
The echo sounder either pings normally displaying the echo
signal received at the transducer, or it replays a previously
recorded echo signal stored in one of the four Raw Data
Memory locations.
Normal - Click the Normal button to enter Normal ping mode.
Replay - Select Replay for Replay (playback) mode.
Files - When selecting Replay mode, click the Files button to
activate the Replay dialogue to select the replay file.
External trigger
The Auxiliary connector on the General Purpose Transceiver
(GPT) includes a trigger input signal for transmit
synchronisation with external equipment. Normally, the EQ60
transmits as soon as it is ready for the next ping. Transmission is
delayed until a pulse is detected at the trigger input line when
the Extern Trig entry is checked.
Click this option to enable the EQ60 to work in Slave mode.
The echo sounder will then await the external trigger from the
peripheral system, and the transmissions from the systems will
be synchronized.
When this option is not checked, the EQ60 operates normally as
a Master system.
The external triggering system is explained in more detail in the
EQ60 instruction manual. Refer to the Cable layout chapter in
the printed book.
Note
External transmit synchronisation is only active in Normal ping
mode.
History
Echogram pictures are saved continuously to the harddisk when
the Save box is checked.

Ping rate
These settings are used to define how fast the echo sounder shall
transmit (”ping”). When the Maximum box is selected, the
EQ60 transmits at maximum speed only limited by the speed of
sound in water and/or processing delays. Selecting Single Step
allows the EQ60 to conduct just one ping cycle every time the
Step! entry on the Main menu is clicked, or the keyboard
comination Alt+E is pressed.
Selecting Interval sets the echo sounder to transmit once at
every chosen time interval (in seconds).

Transceiver Installation
This dialogue box controls installation and un-installation of
transceivers. The dialogue box is accessed from the Install
menu. Prior to this, all echo sounder activity must be stopped.
When accessed, an opening dialogue allows you to either:
• Inspect the transceiver installations
• Modify the transceiver installations
• Cancel the operation
Every time the Transceiver Installation dialogue appears on
the display the echo sounder software performs a search for
transceivers. The ISA bus is searched for PC Transceiver
plug-in boards, while General Purpose Transceivers (GPT)
connected to the Ethernet interface are identified. The complete
transceiver list is then displayed.
Transceiver list
A single frequency transceiver occupies one entry in the list, and
a dual frequency transceiver occupies two. Each entry contains:
• transceiver type
• operating frequency
• unique identifier
• frequency channel number
• transducer type
The General Purpose Transceivers use their Ethernet addresses
for unique identification.
The PC Transceivers use their ISA bus parameters; IO address,
DMA channel and IRQ number for identification.
112
857-164342 / Rev.C
Instruction manual
The frequency channel number identifies individual channels
within a multi-frequency channel transceiver.
Frequency channels
Hence, the echo sounder system consists of a number of
frequency channels. Entries in the frequency channel list are
shown in black, green or red colour. Detected channels that are
not installed are shown in black. The phrase NONE replaces the
transducer type name for uninstalled channels. Detected
channels that are installed are shown in green colour. Installed
channels that were not detected during the search for
transceivers are shown in red colour.
Each entry in the Frequency Channel Selection list belongs to
a transceiver. The lower part of this dialogue box displays
information about the currently selected transceiver. The first
information line displays the transceiver personality string.
Remaining lines display specific transceiver information.

Communication with the ITI system is based on NMEA
telegrams. The EQ60 may transmit depth telegrams to the ITI.
Useful input telegrams from the ITI are automatically
interpreted.
• The $IIDBS telegram contains the headrope depth.
• The @IIHFB telegram contains the vertical distance between
the headrope and the footrope.
Trawl opening
A fixed headrope-to-footrope distance can be manually entered.
This is used for trawl sensor systems not measuring the trawl
opening, or when the measured headrope-to-footrope distance is
unreliable. Enable for manual setting in the check box, and enter

(GPT).
If only one GPT is used, you need a twisted pair cable with
swapped receive and transmit wires. The cable is connected
between the GPT and the echo sounder’s Operator Station.
An Ethernet hub is required if your system includes more than
one General Purpose Transceiver.
Note
Straight through ethernet cable must be used.
Serial lines
Connect navigation receiver, trawl system and heave sensor with
serial line output to the rear of the echo sounder computer using
RS-232 cables. Heave sensors with an analog output are
connected directly to the Auxiliary connector of the nearest
transceiver.
Synchronization
Synchronous transmission is desirable if there are several echo
sounders onboard the vessel. For every echo sounder and every
transceiver onboard the ship, connect the appropriate pins at the
Auxiliary connectors together using a two-wire cable.

Simrad EQ60
Parts and configurations
Overview
The Simrad EQ60 echo sounders is designed as a modular
system. It supports a variety of configurations and frequency
options.
A standard EQ60 fishery echo sounder delivery consists of:
• Transducer(s)
• Display Unit with built-in Processor Unit
• Pointing device (mouse or rollerball)
• Optional devices:
- Ethernet switch (if the system comprises more than one
General Purpose Transceiver (GPT))
- Transceiver(s)
The EQ60BB is supplied without display.
Transducer
One or more transducers are included.
The basic EQ60 configuration accepts one or two transducers.
Only two alternatives are available: 38/200 or 50/200. If
additional transducers, or other frequencies, are required, a
General Purpose Transceiver (GPT) must be implemented.
A single frequency General Purpose Transceiver (GPT) accepts
one transducer, and a dual frequency GPT accepts two
transducers.
A large number of transducers are available from Simrad. There
are several transducer alternatives for each operating frequency
with different beam widths, power rating and mounting
arrangements.
All transducers are rated 60 or 75 ohms. Each has an efficiency
of approximately 50%.
Transceiver
The basic EQ60 configuration includes one PC Transceiver
(PCT). It is mechanically integrated with the display unit.
Optional, the high performance and highly flexible General
Purpose Transceiver (GPT) may be added to the system.
122
857-164342 / Rev.C
Installation
PC Transceiver
The PC Transceiver comprises a complete dual frequency
single beam system on a computer circuit board. The PCT fits
inside the echo sounder unit, and it is powered directly from the
sounder’s internal power supply. Only one PCT board can be
installed. On a new system, the PC Transceiver is installed and
tested by Simrad prior to delivery. There are no need for the
user to open the echo sounder cabinet.
The PC Transceiver is available in two configurations. Both are
designed for the fishery community:
• PCT-S38(1)/S200(1)-F
- This circuit board contains a single beam 38 kHz 1 kW
channel, and a single beam 200 kHz 1 kW channel.
• PCT-S50(1)/S200(1)-F
- This circuit board contains a single beam 50 kHz 1 kW
channel, and a single beam 200 kHz 1 kW channel.
General Purpose Transceiver
The General Purpose Transceiver (GPT) is a small
self-contained unit containing its own power supply. It operates
from +12 Vdc or 115-230 Vac. The unit can be mounted
anywhere on board the ship, provided that the location is dry
and ventilated. Power cable and mounting brackets are enclosed.
We recommend that the GPT is mounted as close to the
transducer(s) as possible.
The GPT for the EQ60 is only available in single beam
configuration. However, a dual frequency single beam
configuration is provided. Possible operating frequencies are 12,
18, 27, 38, 50, 70, 120 and 200 kHz.
Typical configurations include:
• GPT-S38(4)-F (single beam 38 kHz, 4 kW)
• GPT-S50(4)-F (single beam 50 kHz, 4 kW)
• GPT-S70(1)-F (single beam 70 kHz, 1 kW)
• GPT-S120(1)-F (single beam 120 kHz, 1 kW)
• GPT-S200(1)-F (single beam 200 kHz, 1 kW)
• GPT-S38(1)/S50(1)-F (single beam 38 and 50 kHz, 1+1 kW)
Two or more General Purpose Transceivers (GPT) can exist on
the same Ethernet cable. A multi-frequency sounder emerges
simply by using several transceivers on the Ethernet cable.
It is even possible to combine one internal PC Transceiver with
a number of external General Purpose Transceivers.

Introduction
Any Microsoft Windows® compatible printer may be connected
to the EQ60 Processor Unit. The connection is made with a
standard Centronics type parallel cable.
Hardware installation
Refer to the applicable printer documentation for hardware
installation. Make sure that the printer is securely mounted to
withstand the shock, vibrations and movements experienced on
a ship.
Software installation
In order to use the printer, you must install the necessary
driver(s) and set up the EQ60 Processor Unit so that the
presence of the printer is known. To do this, you will need to
use the standard Microsoft Windows® tools on the computer.
In this procedure, a Hewlett Packard 970C colour printer is used
as an example.
Note

External interfaces
Overview
The echo sounder provides one or more multi purpose RS-232
ports (9-pin male D-connector) for external interfacing. On the
Simrad EQ60, these are used for:
• Navigation (GPS) interface (NMEA)
• Annotation text input (NMEA)
• Depth telegram output (NMEA)
• Heave sensor input
• Post-processing data (ethernet interface)
• ITI (Integrated Trawl Instrumentation) communication
• Purse seine
• Temperature sensor input
An analogue heave sensor and a temperature sensing thermistor
may be connected directly to the Auxiliary connector on the
echo sounder. If an optional General Purpose Transceiver (GPT)
is used on the same system, the sensors must be connected to
either the echo sounder or the GPT.
A colour printer may be connected to the printer port (25-pin
female D-connector) at the side of the echo sounder.
Navigation (GPS)
GPS (Global Positioning System) receivers output NMEA 0183
telegrams containing geographical latitude and longitude. The
defined communication parameters are:
• 4800 bits per second
• 8 data bits
• no parity
• one stop bit
Most navigation receivers also allow different parameters to be
entered.
Connect the navigation receiver to a free RS-232 port. Only the
signal (Rx, pin 2) and ground wires (pin 5) need to be
connected. Connect only the signal wire (Tx, pin 3) and the
ground wire (pin 5) to the GPS system’s output. Maximum
cable length is approximately 50 meters.
The connection must be established in the software as well.
Observe the following procedure:
1
Open the Navigation Interface dialogue box.
134
857-164342 / Rev.C
Cable layout
2
Enter the name of the selected RS-232 port and the
communication parameters.
Annotation
Annotation messages may be input on the same serial line as the
navigation system. The $??ATS format is used, and it has the
following format..
$??ATS,this is a test<CR><LF>
The telegram header consists of:
1
the $ character
2
two letters ?? (disregarded by the echo sounder, identifies
the sender of the telegram)
3
three letters ATS (Annotation Text String - identifies the
type of NMEA telegram).
4
a comma (NMEA separation character).
5
Text string (The echo sounder handles the string as an
ordinary text. You can not use commas in the text string!)
6
A carriage-return and line-feed pair completes the
telegram.
The ASCII telegram with the external annotation must be
connected to the same serial line as the navigation system.
Depth output
The current depth from a defined transceiver channel can be
sent out on a chosen serial line. One or more of the following
serial lines can be used:
• Heave Sensor
• Navigation Interface
• Trawl Interface
The dialogue boxes used to control these interfaces also include
a button to open the Depth Output dialogue box. From this
dialogue, you can select from three different types of NMEA
depth telegrams.
• The $SDDBS telegram contains the depth below the surface.
• The $SDDBT telegram contains the depth below the
transducer.
• The $SDDPT telegram contains the depth below the
transducer and the distance between the transducer and the
waterline.
857-164342 / Rev.C
135
Simrad EQ60
The EQ60 can also output the EA 500/EK500 compatible depth
telegrams; D1, D2 etc. Output for Atlas echo sounders are also
provided.
Only one telegram type at a time can be generated, and the same
serial line parameters as for the main sensor must be used.
Trawl system
Communication with the Simrad ITI (Integrated Trawl
Instrumentation) is based on NMEA telegrams.
Connect the ITI to a free RS-232 port. Only the receive signal
wire (Rx, pin 2), the transmit signal wire (Tx, pin 3) and the
ground wire (pin 5) need to be connected.
Maximum cable length is approximately 50 meters.
The connection must be established in the software as well.
Observe the following procedure:
1
Open the Trawl Interface dialogue box.
2
Enter the name of the selected port.
3
Enter the following communication parameters: 4800 bits
per second, 8 data bits, no parity, one stop bit.
Post-processing data
The EQ60 can communicate with an external post-processing
chart plotter system using the ethernet interface. This
communication is controlled by the BI500 dialogue box.
The following telegrams may be used:
• Parameter
• Echogram
• Echo Trace
• Navigation
• Vessel Log
The interface will require the absolute identity of the remote
UDP port and the remote IP address.
Heave sensor
A heave sensor with an analogue output is connected directly to
the Auxiliary connector.
The positive heave input signal (pin 3) is connected to the
sensor output terminal. The negative heave input signal (pin 16)
is grounded at the sensor in order to prevent ground potential
offsets between the sensor and the transceiver from adding to
the sensed signal.
136
857-164342 / Rev.C
Cable layout
Maximum cable length is virtually unlimited.
The connection must be established in the software as well.
Observe the following procedure:
1
Open the Heave Sensor dialogue box.
2
Select the appropriate transceiver.
Heave sensors with a serial line output are connected to a free
RS-232 port at the rear of the computer. Maximum cable length
is approximately 50 meters. In these cases, use the Heave
Sensor dialogue box to enter the required communication
parameters and the name of the selected port.
Temperature sensor
Connect the temperature sensing thermistor to the Auxiliary
connector (pins 4 and pin 17).
Observe that pins 2 and 4 of the PC Transceiver’s Transducer
connector are internally interconnected with pins 4 and 17 of the
Auxiliary connector.
Purse seine
Communication with the Simrad PI30 (Purse Seine system) is
based on NMEA telegrams.
Connect the PI30 to a free RS-232 port at the rear of the
computer. Only the receive signal wire (Rx, pin 2), the transmit
signal wire (Tx, pin 3) and the ground wire (pin 5) need to be
connected. Maximum cable length is approximately 50 meters.
The connection must be established in the software as well.
Observe the following procedure:

External triggering
Overview
Whenever more than one hydroacoustic system (echo sounder or
sonar) is installed on a vessel, interference may occur. To avoid
this, the systems may either be connected to a common
synchronization system, or one of the acoustic systems may be
defined as a “master”.
The EQ60 echo sounder include interface for remote transmit
synchronisation. The system can be set up to operate in either
Master or Slave mode in relation to an external synchronization
or hydroacoustic system.
The EQ60 system may comprise more than one General Purpose
Transceiver (GPT). If the EQ60 operates as a Master, the
synchronization between these are controlled by the echo
sounder software. If the echo sounder operates as a Slave
system, the GPT units must be individually controlled by the
Master system.
Note
In its default configuration, the EQ60 is set up to operate as a
Master. Special action must be taken to reconfigure the echo
sounder for Slave operation.
Master system
When the EQ60 system is set up to operate as a Master in a
system, the TrigOut signal from the GPT Auxiliary connector
must be connected to the external trigger input on the other
hydroacoustic system(s). If more than one GPT us used by the
Master system, the TrigOut signal must be taken from the
active GPT. Two TrigOut signals are available for either
positive or negative triggering. When activated. the trigger
signal will allow all the systems to transmit simultaneously.
Note
Simultaneous transmission of more than one system can only
take place if the systems operate with different frequencies!
→
The cable and connections to the GPT is shown on page 151.
The TrigOut+ signal is an open collector output (max 100 mA)
containing a 100-kohm pullup resistor to +5 Vdc. This signal is
normally low. The TrigOut+ signal goes high when the
transceiver is ready to transmit, and it goes low again when all
frequency channels of the transceiver have finished transmitting.
TrigOut- is the inverse of TrigOut+.
Connect the ground wire to one of the Ground pins (18-22).
857-164342 / Rev.C
139
Simrad EQ60
Slave system
If an external system is used to provide the transmit trigger, the
trigger signal must be connected to one of the TrigIn inputs on
the GPT Auxiliary connector. When activated. the trigger signal
from the external system will allow the EQ60 system to
transmit.
If more than one GPT is used by the Slave system, the input
trigger must be connected to all the GPT units in parallel.
Two TrigIn inputs are available for either positive or negative
triggering. The TrigIn- input is sensitive to a high-to-low
transition.
Connect the ground wire to one of the Ground pins (18-22).
Note
If the EQ60 system comprises more than one GPT unit, the
external trigger must be connected in parallel to every GPT.

Transducer(s)
The cables described in this chapter are used to connect the
General Purpose Transceiver (GPT) to one or more transducers.
The following transducer types may be used:
• Single frequency, single beam
• Single frequency, dual beam (wide and narrow)
• Dual frequency, single beam (combi)
→
The plug housing is shown on page 160.
For the majority of the transducers, the cables are supplied from
the manufacturer. These are normally physically fastened to the
transducer.
If the distance between the transducer and the transceiver
exceeds the length of the cable, a junction box must be used.
The cable between the junction box and the transceiver must
then be supplied by Simrad, and this must be the same type as
used on the transducer(s).
Note
All transducer cables must be run in steel conduits. Use flexible
conduit close to the transceiver.
Note
Cable shields must be connected to the plug housing. The
shields must not be connected to ship’s ground anywhere
between the transducer and the plug on the transceiver.
→
The termination of the cable shielding is shown on page 160.
Observe the cabling diagrams.
857-164342 / Rev.C
153
Simrad EQ60
Single frequency, single beam
The next two drawings show how to connect a single frequency,
single beam transducer to the system. Note that two different
connections are made, depending on the rated power output.
Low power output is achieved when the GPT is equipped with a
single transmitter board. In most systems, this will result in a 2
kW output power, but older GPTs may only be capable of
supplying 1 kW.
Note:
1) All transducer cables must be run in
steel conduits. Use flexible conduit closer
to the transceiver.
2) Cable shields must be connected to
the plug housing.
3) Cable shields must not be connected to
ship's ground in the junction box.

Basic cabling requirements
Cable trays
All permanently installed cables associated with the system
must be supported and protected along their entire lengths using
conduits and/or cable trays. The only exception to this rule is
over the final short distance (max. 0.5 metre) as the cables run
into the cabinets/units to which they are connected. These short
unsupported lengths are to allow the cabinets to move on their
shock mounts, and to allow maintenance and replacements.
• Wherever possible, cable trays must be straight, accessible
and placed so as to avoid possible contamination by
condensation and dripping liquids (oil, etc.). They must be
installed remote from sources of heat, and must be protected
against physical damage. Suitable shields must be provided
where cables are installed in the vicinity of heat sources.
• Unless it is absolutely unavoidable, cables should not be
installed across the vessel’s expansion joints. If the situation
is unavoidable, a loop of cable having a length proportional
to the possible expansion of the joint must be provided. The
minimum internal radius of the loop must be at least twelve
times the external diameter of the cable.
• Where a service requires duplicate supply lines, the cables
must follow separate paths through the vessel whenever
possible.
• Signal cables must not be installed in the same cable tray or
conduit as high-power cables.
• Cables containing insulation materials with different
maximum-rated conductor temperatures should not be
bunched together (that is, in a common clip, gland, conduit or
duct). When this is impractical, the cables must be carefully
bunched such that the maximum temperature expected in any
cable in the bunch is within the specifications of the
lowest-rated cable.
• Cables with protective coverings which may damage other
cables should not be bunched together with other cables.
• Cables having a copper sheath or braiding must be installed
in such a way that galvanic corrosion by contact with other
metals is prevented.
• To allow for future expansion of the system, all cables should
be allocated spare conductor pairs. Also, space within the
vessel should be set aside for the installation of extra cables.
162
857-164342 / Rev.C
Cable layout
Radio Frequency interference
All cables that are to be permanently installed within 9 m
(30 ft) of any source of Radio Frequency (RF) interference such
as a transmitter aerial system or radio cabin, must, unless
shielded by a metal deck or bulkhead, be adequately screened by
sheathing, braiding or other suitable material. In such a situation
flexible cables should be screened wherever possible.
It is important that cables, other than those supplying services to
the equipment installed in a radio room, are not installed
through a radio room. Cables which must pass through a radio
room must be screened by a continuous metal conduit or
trunking which must be bonded to the screening of the radio
room at its points of entry and exit.
Physical protection
Cables exposed to the risk of physical damage must be enclosed
in a steel conduit or protected by a metal casing unless the
cable’s covering (e.g. armour or sheath) is sufficient to protect it
from the damage risk.
Cables exposed to an exceptional risk of mechanical damage
(for example in holds, storage-spaces and cargo-spaces) must be
protected by a suitable casing or conduit, even when armoured,
if the cable covering does not guarantee sufficient protection for
the cables.
Metallic materials used for the physical protection of cables
must be suitably protected against corrosion.
Grounding
All metallic cable coverings (armour, lead sheath etc.) must be
electrically connected to the vessel’s hull at both ends except in
the case of final sub-circuits where they should be connected at
the supply end only.
Grounding connections should be made using a conductor which
has a cross-sectional area related to the current rating of the
cable, or with a metal clamp which grips the metallic covering
of the cable and is bonded to the hull of the vessel. These cable
coverings may also be grounded by means of glands specially
intended for this purpose and designed to ensure a good earth
connection. The glands used must be firmly attached to, and in
good electrical contact with, a metal structure grounded in
accordance with these recommendations.
Electrical continuity must be ensured along the entire length of
all cable coverings, particularly at joints and tappings. In no case
should the lead-sheathing of cables be used as the only means of
grounding cables or units.
857-164342 / Rev.C
163
Simrad EQ60
Metallic casings, pipes and conduits must be grounded, and
when fitted with joints these must be mechanically and
electrically grounded.
Cable connections
All cable connections are shown on the applicable cable plan
and interconnection diagrams.
Where the cable plan shows cable connections outside an
equipment box outline, the connections are to be made to a plug
or socket which suits the plug or socket on that particular item
of equipment.
Where two cables are connected in series via a junction box or
terminal block, the screens of both cables must be connected
together but not grounded.
Cable terminations
Care must be taken to ensure that the correct terminations are
used for all cable conductors, especially those that are to be
connected to terminal blocks. In this case, crimped
sleeve-terminations must be fitted to prevent the conductor core
from fraying and making a bad connection with the terminal
block. It is also of the utmost importance that where crimped
terminations are used, the correct size of crimp and crimping
tool are used. In addition, each cable conductor must have a
minimum of 15 cm slack (service loop) left before its
termination is fitted.
Cable identification
Cable identification codes corresponding to the cable number
shown in the cable plan must be attached to each of the external
cables. These identification codes should be positioned on the
cable in such a way that they are readily visible after all panels
have been fitted. In addition, each cable conductor should be
marked with the terminal board number or socket to which it is
connected.

Cable gland assembly procedure
Purpose
Cable glands are used whenever a cable passes through a
water-tight bulkhead or into a cabinet, to seal the opening
through which the cable passes and to protect the cable from
abrasion on the edges of the hole. Follow the guidelines detailed
here when installing cables through cable glands.
Note
There are many different types of cable gland on the market.
This procedure describes the types used (now and previously) as
standard in the units manufactured by Simrad. The cable glands
are not supplied with the system.
Even though the cabinets from Simrad may be prepared for
specific types, the installation shipyard will be responsible for
selecting cable gland types and installing them.
Note
The screen in transducer cables must never be connected to
ship’s ground in the cable glands!
General procedure

Note
Ensure all the cables to be connected are completely
isolated from any power sources.
- I.e. Switch off and remove the supply fuses from any
units or systems into which the cables are already
connected.
Select the cable to be connected into the cabinet, and
select the cable gland through which the cable is to pass.
A minimum of 5 cm (recommended 5 - 10 cm) of slack cable
must be allowed, both inside and outside the cabinet, when
installing cables. This is to allow for vibration damping,
maintenance and measurement errors. Always double-check
your measurements before taking any irreversible actions.

Transducer installation
TRANSDUCER INSTALLATION
Transducer location
General
A single answer to the question where to locate the transducer
cannot be given. It depends very much on the vessel’s
construction. However, there are some important guide lines.
Go deep
The upper water layers of the sea contain a myriad of small air
bubbles created by the breaking waves. In heavy seas the
uppermost 5 to 10 metres may be air-filled, with the highest
concentrations near the surface. Air bubbles absorb and reflect
the sound energy, and may in worst cases block the sound
transmission totally. Therefore, mount the transducer at a deep
position on the hull.
Consider the situation when the vessel is unloaded, and when it
is pitching in heavy seas. The transducer must never be lifted
free of the water surface. Not only will the sound transmission
be blocked, but the transducer may be damaged by slamming
against the sea surface.
Another reason to go deep is cavitation in front of high power
transducers. Cavitation is the formation of small bubbles in the
water due to the resulting local pressure becoming negative
during parts of the acoustic pressure cycles. The cavitation
threshold increases with the hydrostatic pressure.
Boundary water layer
When the vessel forces its way through the sea, the friction
between the hull and the water creates a boundary layer. The
thickness of the boundary layer depends upon vessel speed and
the roughness of the hull. Objects protruding from the hull, and
dents in the hull, disturb the flow and increase the thickness of
the boundary layer. The flow in this boundary layer may be
laminar or turbulent. A laminar flow is a nicely ordered, parallel
movement of the water. A turbulent flow has a disorderly
pattern, full of eddies. The boundary layer increases in thickness
when the flow goes from laminar to turbulent. Figure 16 (next
page) sketches the boundary layer of a vessel moving through
the water.
Furthermore, air bubbles in the sea water are pressed down
below the hull and mixed into the boundary layer. The boundary
857-164342 / Rev.C
173
Simrad EQ60
layer is thin underneath the forward part of the vessel, and
increases in thickness as it moves towards aft. If the sides of the
hull are steep, some of the air bubbles in the boundary layer may
escape to the sea surface along the vessel sides. It is our
experience that a wide and flat bottom, with a rising angle less
than around 13 degrees, is prone to giving air problems for the
transducer. In any case a transducer location in the forward part
of the hull is preferred in order to minimise the influence of the
boundary layer.
Turbulent flow
Laminar flow
Aerated water
(CD3002)
Figure 16 Sketch of the boundary layer underneath the vessel.
Propeller noise
The propulsion propeller is the dominant noise source on most
fishing vessels, research vessels, merchant vessels and pleasure
crafts. The noise is transmitted through the sea water. Therefore
the transducer should be placed far away from the propeller,
which means on the fore part of the hull. Positions outside the
direct line of sight from the propeller are favourable. On small
vessels with short distances it is advised to mount the transducer
on that side of the keel where the propeller blades move
upwards, because the propeller cavitation is strongest on the
other side. The cavitation starts most easily when the water
flows in the same direction as the propeller blade, and that is to
some degree the case at that side of the keel where the propeller
blades move downwards.
Bow thruster propellers are awful machines. When they are in
operation, the noise and cavitation bubbles make the echo
174
857-164342 / Rev.C
Transducer installation
sounder useless, almost no matter where the transducer is
installed. And when not in operation, the tunnel creates
turbulence, and if the vessel is pitching, the tunnel may be filled
with air or aerated water in the upper position and release this in
the lower position. Therefore, an echo sounder transducer
should be placed well away from the bow thruster.
Vessel heave
Heave is the up and down movement of the vessel. It disturbs
the echo traces in the echogram, so that a flat bottom is
displayed as a wave. A transducer location in the middle of the
vessel minimises the influence of vessel roll and pitch.
Noises from protruding objects on the hull
Objects protruding from the hull, such as zinc anodes, sonar
transducers or even the vessel’s keel, generate turbulence and
flow noise. Also holes and pipe outlets are noise sources. They
may act as resonant cavities amplifying the flow noise at certain
frequencies. Do not place an echo sounder transducer in the
vicinity of such objects, and especially not close behind them.

Simrad EQ60
Summary
Some of the above guide lines are conflicting, and each case has
to be treated individually in order to find the best compromise.
Generally the propeller noise is the dominant factor, and a
recommended transducer location is in the fore part of the hull,
with maximum distance from the bow equal to one third of the
total length of the hull at the water line.
→
See figure 17.
If the vessel hull has a bulbous bow, this may well be a good
transducer location, but also here must be taken into
consideration the flow pattern of the aerated water. Often the
foremost part of the bulb is preferable.

Transducer installation
Ways of mounting the transducer
Inclination of the transducer face
Incline the transducer face approximately 3 degrees, so that the
flowing water meets it directly. This assures laminar water flow.
Mounting screws should not be extruding from the transducer,

A fairing, made by the shipyard, is placed between the
transducer and the hull, to adapt for the deadrise angle of the
hull. The fairing can be made of wood or steel, and should have
the same outline dimensions as the transducer. These
transducers are mainly used on smaller vessels. A location
approximately 0.5 m aside from the keel may be adequate for
the passage of water between the keel and the transducer. The
figures above and below illustrate external mounting of
transducers on steel hulls and on wood or polyester hulls
respectively.

Transducer blister
Other transducers are designed for installation into the hull or in
a blister. In general, a blister installation is the recommended
method. It brings the transducer below the boundary layer. A
blister is illustrated below.

Figure 21 Transducer blister
The best performance is obtained with a blister height of 40 cm
or more. A streamlined shape and rounded edges reduce the
flow noise. A vertical leading edge or front will guide the
aerated water to the sides of the blister. The orientation of the
blister should follow the water flow. On a conventional hull
shape, without a bulb, the front of the blister should have a few
degrees toe-in towards the bow.
→
See figure 22.
The blister is placed on one of the sides of the hull, and the
distance from the keel is a trade off between a close distance
giving a turbulent flow of water in a narrow passage, and a large
distance bringing the transducer higher up and also more
affected by vessel roll. Normally a distance of approximately 1
m is a good compromise.
→
See figure 23.
The interior of the blister must be filled with sea water. Use
drainage holes in the bottom and an air outlet on the top. The
water pressure behind the transducer will then compensate for
the outside pressure during vessel movements in rough sea.

The transducer cable penetrates the hull in a stuffing tube, see

In a box keel
(CD3008)
Vessels with a box keel may use this for transducer installation.
The box keel is already the deepest part of the vessel. If the box
keel is too narrow to accommodate the transducer, it can be
widened, either symmetrically or to one side only. In the last
case the installation could also be described as a blister merged
into the keel. The figure below illustrates a symmetrical box
keel installation.

Transducer installation
Retractable transducer
Retractable hull units are commonly used for horizontal looking
sonars. When not in use, the transducer is retracted into a trunk.
The retractable hull unit is more expensive than a blister, but on
vessels having a hull where it is difficult or impossible to install
a blister, it may be worth-while. A retractable hull unit with
transducer is shown below.
Vessels without a keel and with a wide, flat bottom is an
example where a retractable hull unit can be the only acceptable
method for bringing the echo sounder transducer below the
boundary layer.

Centre board
The use of a centre board with the purpose of stabilising the
vessel is well known. A centre board is also a superior platform
for transducers. Such instrument keels have been built, mainly
on research vessels, with a length of 3 m, protruding also 3 m
below the hull, see the figure below. At that depth, the water is
free of air bubbles up to very high sea states. The vessel is then
able to perform reliable acoustic measurements in open sea a
larger part of the year.

Flush mounting in a steel tank
Flush mounting is used on very large vessels with a hull so deep
that no air bubbles are found below the hull, and on vessels
operating in shallow harbours or waters, where a protruding
blister can not be accepted.
The standard procedure for flush mounting on a steel vessel is to
weld a steel tank inside the hull, and mount the transducer into
this tank. As for a blister, the interior of the tank must be filled
with water. This can be accomplished by air release through a
steel tube, which is extended either to open air 1.5 m above the
water line or to the water outside the hull at a point higher than
the tank interior. If the tube is extended to open air, drainage
must be provided with leakage at the transducer flange or a
separate hole in the tank bottom. Transducer mounting in a steel
tank is shown in the figure below.

Behind a protective acoustic window
Vessels operating in arctic waters need special attention on
transducer installation. Floating blocks of ice may damage even
a flush mounted transducer face. For this situation Simrad offers
‘’arctic tanks’’ in different sizes.
The transducer shown in the figure below is mounted inside the
tank behind a strong acoustic window which could be made of
polycarbonate. The tank is oil filled.

Transducer installation
Inside the hull
An installation of the transducer inside the hull, and sounding
through the hull, requires a good acoustic contact between the
transducer face and the hull. Build a tank around the transducer
and fill it with a liquid. Oil used in hydraulic systems is a well
suited liquid for this purpose. It contains no gas bubbles and is
non-corrosive.
The tarnsducer can be mounted inside the hull. A substantial
loss must be expected when the sound passes through the hull.
→
Refer to figure 29.
Typical values of the two way loss are 3 dB for polyester, 6 dB
for aluminium and 10 dB for steel. Hulls made of wood or a
sandwich type with foam in the middle, attenuate the sound so
much that through hull sounding must be regarded as
impossible. The loss varies with the distance between transducer
face and the hull. The best result is obtained when the distance
is half a wavelength. Consult Simrad for advice. In addition to
the loss, the beam pattern is degraded, because a larger area of
the hull is set into vibrations.

Cable in steel conduit
It is strongly recommended to lay a steel conduit from the
transducer to the echo sounder transceiver, and draw the
transducer cable through the conduit. There are two reasons for
this procedure.
• First, it will make it easier at a later stage to replace the
transducer.
• Second, noise and interference from other electrical
equipment is greatly reduced.
With a steel conduit the installation satisfies the EU regulations
for EMC interference. Without a steel conduit, there is a risk of
reduced echo sounder performance.

Transducer installation
The tube should be unbroken and watertight from the transducer
to above the water line. From there, openings or a junction box
can be installed to facilitate drawing of the cable, or to add a
cable extension. However, the tube should act as a continuous
electrical screen all the way and be connected to the transceiver
chassis.
Tube dimensions:
• minimum 35 mm inner diameter
• minimum 6 mm wall thickness (4.5 mm if galvanised).
If two or more transducers are installed close to each other it is
possible to pull their cables in the same steel tube, provided the
tube diameter is increased accordingly. However, for easy
replacement it is recommended that each transducer has its own
steel tube.
Most Simrad transducers are delivered with 20 m cable. Excess
cable can be cut off, or an extension cable can be added. This is
possible because all Simrad transducers have a built-in
transformer for tuning and matching to the cable impedance of
75 Ohms.

Handling and maintenance
Do not lift the transducer by the cable.
Some transducers are delivered with a cover plate on the face
for protection during transport. Let this plate stay on as long as
possible, but do not forget to remove it before the vessel goes
into the sea.
An anti-fouling paint may be applied to the transducer face.
Because some paint types may be aggressive to the polyurethane
in the transducer face, please consult Simrad’s list of approved
paints on the next page.
Note
Arctic tanks have acoustic windows made of polycarbonate.
These must neither be painted nor cleaned with chemicals.
During dry docking of the vessel, the transducer face may be
cleaned for shells and other marine fouling. Be careful not to
make cuts in the transducer face. Use a piece of wood or a very
fine grade emery paper.
