SAFETY PRECAUTIONS
3 SAFETY PRECAUTIONS
3.1 Chapter Overview
This chapter contains information as to the safety precautions that should be
taken in handling and operating your SeaBat™ system.
3.2 Operator Safety
The SeaBat 7111 system should be handled with attention to operator safety as
well as protection of the hardware components. General precautions include:
• DO NOT connect or disconnect cables with power on.
• DO NOT attempt to open and service the Projector or Receiver Units.
• DO NOT attempt to open and service the system unless you have been
specially trained and certified by RESON.
• DO NOT operate the system while divers are in the water and closer
than 2 meters from the Projector and Receiver Units. High powered
ultrasonic energy can be hazardous to human physiology.
• DO NOT touch or handle any internal printed circuit boards without
specific instructions from RESON.
• DO NOT transmit while the vessel is in dry dock.
• DECREASE Power gradually (rather than simply switching OFF) to
prevent lethal voltages from being stored in the Transceiver Unit.
• ALWAYS ensure the transmitter voltage has reached 0 before
powering down the system.

March 13, 2007
SAFETY PRECAUTIONS
3.3 Equipment Safety
Each SeaBat™ component is sufficiently robust for shipboard storage while in its
own transit case or shipping box. There are handles and tie-down rings provided
on these boxes. Use appropriate discretion in lifting these components, as the
cases may be awkward and heavy.
To ensure safe handling of the equipment:
• Inspect each transit case or shipping box for physical damage prior to
opening, and each component for physical damage before installation.
• Use adequate packaging and shock-absorbing materials to ship or
store any equipment outside the supplied transit cases.
• Do not drop the equipment.
• Do not place the Sonar Head in an area where the face may be
scratched or damaged.
• Do not place liquids on or near the equipment.
• Do not smoke or spill ashes on or near the pointer device.
• Ensure that the equipment is properly secured before putting out to sea.
• While operating in air, set your SeaBat™ system to the lowest possible
setting. A higher setting may damage the transmit array ceramics.
3.4 Exposure to Sunlight
Do not allow the Sonar Head to sit in direct sunlight when not in use. In addition
to furthering corrosive effects, continued exposure to UV rays will damage the
polyurethane surface.

INSTALLATION INSTRUCTIONS
4 INSTALLATION INSTRUCTIONS
4.1 Chapter Overview
This section will provide information specific to the installation of your SeaBat
7111 system. Before you begin, make certain that you have all of the
components of your SeaBat™ system.
• 7-P Sonar Processor Unit
• Transceiver Unit
• Sonar Head
• Cable Assemblies
4.2 Dry End Installation
Following are instructions for use when installing the Dry End components of the
SeaBat 7111 system.
4.2.1 Sonar Processor Unit
The Sonar Processor may be either rack or table mounted. It must be in an area
that is not exposed to the weather, but is within easy reach of both the operator
and the Transceiver to Processor Interconnect Cable. Allow clearance around
the unit to provide adequate air circulation and easy access to the power switch.
There are power switches located on both the front and rear panels of the Sonar
Processor Unit. Once the system is installed, set the switch on the rear of the unit
to the "On" position. Any further powering up, powering down, or resetting of the
Sonar Processor should be done by opening the right front door (by pushing on
the top left corner of the door) and pressing the toggle switch.
Once the Sonar Processor is installed, the only interaction required should be to
depress the power switch and energize the system.

March 13, 2007
INSTALLATION INSTRUCTIONS
4.2.2 Transceiver
Be careful to place the Transceiver in a location that is well within reach both of
the 30-meter Sonar Head to Transceiver Cables and of the Processor to
Transceiver Interconnect Cable. The Transceiver may be located in a dry,
unmanned equipment room as long as the ambient temperature is taken into
consideration (see Table 3: Transceiver Unit, Technical Specifications).
Allow clearance around the unit to provide adequate air circulation and to allow
for connection of cables without the need for sharp bends.
4.2.3 Cable Connections
There are several cable connections to be made at the Dry End of the
installation. These connections are between the Sonar Processor and its
peripheral equipment and between the Sonar Processor and the Transceiver.
The critical connections are shown in Figures 5 and 7. All dry-end cables come
with factory-installed connectors and just need to be attached at the appropriate
port(s).

INSTALLATION INSTRUCTIONS
4.3 Wet-End Installation
Following are detailed instructions for use when installing the SeaBat 7111
system in a single-head configuration.
4.3.1 Mounting
The Sonar Head may be attached to a pole or mounting structure, the side of a
pier, or a frame located on the harbor floor. Use the supplied mounting bracket
and M10 bolts.
The Sonar head should be immersed in water to a depth of at least 2.0 meters to
ensure that noise from the surface (waves) and turbulence generated by the
mounting structure do not degrade performance. Detection range will vary,
depending upon the thermal profile and weather conditions. Before deployment,
an analysis should be conducted to determine the optimum deployment depth for
a pier-mounted system.
The Receive Array receives through a 180° radial sector which may cause
problems with hull and pole mounts. The depth should also be sufficient to avoid
shadows from other obstacles.
4.3.2 Orientation
The Sonar Head should be mounted with the faces of the arrays oriented
horizontally forward (see Figure 6).

INSTALLATION INSTRUCTIONS
4.3.3 Cable Connection
There are fourteen possible connect points at the rear of the SeaBat 7111
Transceiver Unit (Figure 7). These connect points are numbered J1 – J14.
Figure 7: Transceiver Unit, Rear Panel
4.3.3.1
Receive Array Cable
The Receive Array Cable is molded to the Receive Array at the Wet End and
splits into seven separate connectors at the Dry End. Each connector cable will
have a plastic collar indicating a connection number that begins with “P”. Each of
these numbers will have a corresponding “J” number at the rear of the
Transceiver.
Example: Connector P5 on the cable matches the “Transmit and Control” Port
(J5) on the Transceiver rear panel.
SeaBat 7111 Operator’s Manual
Version 1.00
Page 16
March 13, 2007
INSTALLATION INSTRUCTIONS
4.3.3.2
Transmit Array Cable
The Transmit Array Cable (Figure 19) is molded to the Transmit Array at the Wet
End and splits into four separate connectors at the Dry End. Each connector
cable will have a plastic collar indicating a connection number that begins with
“J.” Each of these numbers will have a corresponding “J” number at the rear of
the Tuning Box.
WARNING: Do not start a bend in either of these cables until at least 29
mm above the molded collar of the array, and use a minimum Bend
Radius of 320 mm or a minimum Bend Diameter of 640mm when
positioning the cables.
These cables are very stiff, and a smaller Bend Radius will result in
damage to the cable.
4.3.3.3
Sound Velocity Sensor Cable
The Sound Velocity Sensor may be connected to the Transceiver rear panel and
a second cable fabricated on-site to continue the link to the operating area. This
precludes the requirement to have a special cable attached to the sensor.
4.4 System Checkout
Once the components of your SeaBat 7111 system have been installed, follow
the steps in this section to ensure that the system is working properly.
1. Ensure all system cable connections are tight.
2. Verify that AC power is available for the Sonar Processor Unit.
3. Energize the monitor.
4. Verify that +48 VDC power is available for the Transceiver Unit.
5. Ensure that the Transceiver Unit power switch is in the “On” position.
6. Press the power switch on the Sonar Processor to energize the system.
7. Immediately check the Transmit Power (TxPower) to make certain it is set
to off. (Prolonged transmission in air – even at a low setting – will damage
the Transmit Array ceramics.)
8. If a sound velocity probe and/or a motion sensor are connected, ensure
the data is being correctly read.
WARNING: To ensure proper calibration, do not power up, reboot or
calibrate the system when the Sonar Head is being deployed or retracted,
as the related mechanical noise will affect the measurements.
SeaBat 7111 Operator’s Manual
Version 1.00
Page 17
March 13, 2007
INSTALLATION INSTRUCTIONS
Once the system has been energized, perform the following checks to verify that
the system is operating correctly:
1. Make certain the Transmit Power is set to “OFF”.
2. Set the Range to “120”.
3. Set Gain to its maximum setting.
4. Click the “Settings” button and ensure that “Palette” is set to “Blue-Yellow”.
5. Perform a Receiver check by vigorously rubbing the face of the Receive
Array with fingertips while monitoring the display. A noise pattern should
be visible on the display.
6. Set the Transmit Power to “Full” while an assistant listens to the Projector.
NOTE: n a noisy environment, it may be difficult to hear the transmission,
which should be a series of clicks at an approximate rate of 4Hz on the
120m range.
7. While listening to the clicks, slowly decrease the range setting one step at
a time. The click rate should increase as the range scale decreases.
WARNING: Once the test is complete, turn the Transmit Power (TxPower)
to the OFF setting, so as to avoid damage to the Transmit Array ceramics.

Once the SeaBat hardware has been installed, the system may be started. To do
this, press the power buttons on both the Sonar Processor and Color Monitor.
CAUTION: When using the power switch at the front of the 7-P Sonar
Processor, it is important to note that the switch is a "toggle.” Pressing the
top portion of the switch will cause the Sonar Processor to begin its
power-up sequence. Pressing the bottom portion of the switch will cause
the Sonar Processor to begin its reset process.
DO NOT press the RESET portion of the switch during the start-up or
shut-down process, as this will damage the Sonar Processor.
The 7-P Sonar Processor will power up and boot directly into Windows. No user
name or password is required for standard systems.
To start the sonar, double-click the 7K Control Center shortcut on the desktop.
Select the head configuration and sonar settings, then click the Start button.
5.2 Main Sonar Display Screen
When the software has successfully started, the Main Sonar Display Screen
displays.
5.2.1 View the Main Sonar Page
The initial view presented to the user is for the default device. It comprises sonar
data displays and relevant information. There are two sets of tabbed displays
available to the user: the uppermost tabs are for data display while the lower tabs
are for sonar controls.
The image in the center of the main display screen is called the Sonar Image.
This image shows the complete sector illuminated by a single transmitted ping
and can be represented in either “Sonar Wedge” mode or in B-Scope mode.

5.2.4 A-Scope Display
On the left side of the Main Sonar Display, beside the Wedge (or B-Scope)
Display, is the A-Scope Display. This display allows the operator to view the
details of a single beam or group of beams.
The default axis values are range vs. magnitude. Magnitude is scaled from
minimum to maximum. Range labels can be changed to Time and Sample
Number using the Label Format menu on the Primary Display Settings tab.
• Single Beam Magnitude: Shows the selected beam’s range versus
magnitude.
• Single Beam Magnitude and Phase: Shows the selected beam’s
range versus magnitude and phase.
• Multiple Beam: Shows the range versus magnitude of the selected
beam and three beams on either side of the selected beam.
• Single Beam Magnitude with Zoom: Shows the selected beam’s
range versus magnitude with a zoom control for detailed inspection.
• Single Beam Phase with Zoom: Shows the selected beam’s range
versus phase with a zoom control for detailed inspection.
Place the pointer over the A-Scope display panel and press the right mouse
button to switch between the available displays.
NOTE: Not all displays may be available, depending on the type of data
being received.
5.2.4.1
Using the Zoom Feature
Both the "Magnitude with Zoom" and the "Phase with Zoom" A-Scope displays
have a zoom feature. Three mouse controls are available to the user for
controlling the zoom: Upper Window, Lower Window, and Window Slider. The
mouse controls are located in between the two plots. They appear as three red
rectangles and joining lines regardless of the user-defined color schemes.
• Upper Window / Lower Window: These control the zoom window for
the plot. Clicking within the controls and sliding them up or down will
shorten or lengthen the resulting zoom area to the left.
• Window Slider: Once a window size has been configured, the user can
click and drag the center rectangular slider up or down the Y axis. This
results in the zoom window being applied to different positions on the
plot.

5.2.5 Event Messages
The Alarm indicator appears during normal operation as a green button on the
Main Sonar Page that is labeled "No Alarm." This button will change based on
the status of the SeaBat system.
The Alarm indicator will be one of three levels - indicated by colors:
• Green: Normal Operation. The system is functioning normally, or all
alarms have been acknowledged.
• Yellow: Caution. One or more features may need attention.
• Red: Alarm. The system requires attention or is no longer operational.
To view event messages, click the “Alarm” button.
The "Acknowledge" button in the lower left corner of the dialog allows the
operator to select an alarm and change the status to "Acknowledged." This is an
informational change only. It does not have any effect on the function of the
sonar itself.
When the status of all Caution or Alarm messages have been changed to
"Acknowledged," the Alarm button on the main sonar page will return to green.

5.2.6 Freeze the Sonar Image
Selecting “Freeze” prevents the image on the Main Sonar Page from being
updated while all other sonar functions continue. This allows prolonged viewing
of a particular item when the display is frozen. Select “Resume” to allow updates
to continue.
5.2.7 Maximize the Sonar Image
Selecting “Max” hides the settings tabs and enlarges the Sonar Image to fit the
entire SeaBat window. This allows close inspection of data. Select “Min” to return
the image to normal size and display the settings tabs.
5.2.8 Change Modes
The Mode pull-down allows the operator to select whether to view the current
data being collected or to view a playback of a previously collected file.
To select the desired mode, click the pull-down menu with the mouse and select
one of the following options:
• Manual: View data being collected now.
• Autopilot: Autopilot is an optional mode of operation for the SeaBat
system. This function disables the operator selection of certain
parameters (such as range, gain, and power) and allows the SeaBat to
automatically adjust sonar settings based on the bottom detect data.
See the Autopilot section for details.
• Calibrate (I&Q): Enter the channel data mode. Allows calibration and
intensity measurement operations to be performed. Default display is a
B-Scope.
• Playback: View a previously collected data file.
Selecting “Playback” mode will add the “Playback” tab to the settings portion of
the interface.

5.3 Changing the Sonar Settings
5.3.1 Sonar Settings (Main Menu)
The "Main Menu" tab is the control point for the Projector and Receiver Units.
5.3.1.1
Set the Range (Range)
The “Range” setting determines how far the SeaBat will “see”. The range settings
are operator selected. There are multiple settings in discrete increments.
Select the appropriate range scale to keep the horizontal bottom image at or
above the widest part of the Sonar Wedge:
Diagram A above depicts a proper range setting. Diagram B depicts an
acceptable range setting for a swath that is beginning to fade due to the effects
of Attenuation and Spreading Loss. Diagram C depicts an incorrect range setting.
Notice that the still-useable ends of the swath are being cut off by the limits of the
range setting.
5.3.1.2
Set the Transmit Power (Power)
The “Power” setting allows the operator to increase or decrease the amount of
power (acoustic energy) transmitted into the water.
SeaBat 7111 Operator’s Manual
Version 1.00
Page 28
March 13, 2007
SYSTEM OPERATION
5.3.1.3
Set the Maximum Ping Rate (Max Rate)
In some instances it may be beneficial to force a lower ping rate than the normal
rate associated with a particular range. Examples of this would be instances
when the vessel is moving at a very slow rate, and the operator wishes to
eliminate redundant data; or when the vessel is in a high-reverb environment
where echoes of the previous ping are contaminating the current ping.
The “Max Rate” setting allows the operator to limit the number of pings per
second (p/s), making it lower than the standard ping rate for that range setting.
NOTE: If Max Rate is set to “Off”, the system will not ping or receive data.
If Max Rate is set higher than the sonar's actual maximum ping rate, the
sonar will ping at its actual maximum ping rate.
5.3.1.4
Set the Gain (Gain)
The “Gain” setting allows the operator to select the amount of Receiver Gain
applied to the returned sonar signal (in addition to the calculated Gain).
NOTE: The SeaBat system utilizes Time Varied Gain (TVG) by applying a
variable gain to the signal, based upon the following formula:
Receiver Gain = 2 α R + Sp log R + G
km
m
Where:
α = Absorption Loss in dB/km
Sp = Spreading Loss Coefficient
R = Range in meters
G = Extra Gain from RxGain menu item
m

5.3.1.5
Gain Profile
The current TVG curve may be viewed by pressing the TVG button in the
OCEAN menu.
5.3.1.6
Set the Pulse Length (Pulse Length)
The “Pulse Length” setting allows the operator to change the Pulse Length of the
transmitted signal.
NOTE: For a given power setting, a narrower Pulse Length will provide a
higher resolution at a shorter range. A wider Pulse Length will provide
maximum range with lower resolution image results.
5.3.2 Applying Gates
The "Gates Menu” allows the operator to apply range and/or depth filters (Depth
Gates) to the bottom-detect process to aid in noise reduction and to correct for a
tilted Sonar Head. Gate lines can be optionally displayed on the Sonar Image.
See Primary Display Settings (Filter Lines) for details.

SYSTEM OPERATION
5.3.2.1
Gate Control Switch
There are three choices for Gate functions:
• Absolute
• Adaptive
• No Gates (Gate functionality is turned off)
5.3.2.2
Absolute Gate Parameters
When Absolute gating is selected, the gate ranges or depths are entered in this
section. Either Range or Depth gates may be entered. Select the "Enable"
checkbox for the type of gate desired.
• Range: Applies minimum and maximum Range values as entered in
the “MinRange” and “MaxRange” fields. Only bottom returns within
these range limits will be used in the bottom detection process.
• Depth: Applies the minimum and maximum depth values as entered in
the “MinDepth” and “MaxDepth” fields. Only bottom returns within these
depth limits (Depth Gates) will be used in the bottom detection process.
Use of a motion sensor is required to maintain constant depths during
the ship’s normal pitch and roll action.
Click the “Update” button to finalize changes.
SeaBat 7111 Operator’s Manual
Version 1.00
Page 31
March 13, 2007
SYSTEM OPERATION
5.3.2.3
Adaptive Gate Parameters
The Adaptive gating option "tracks" the bottom based on a window size and
search criteria from beam to beam within a ping.
• Min Depth / Max Depth: The upper and lower gate values will never
reach these stated minimums and maximums.
• Enable Nadir Search Gate: The minimum and maximum nadir depth
gates are used to refine the initial search for the strongest bottom
return, usually from the nadir beam. This initial search gate can be
enabled or disabled.
• Adaptive Window Size: This is a percentage based on the total
samples in the ping. Once the initial bottom detection point is located,
the gates are propagated in each direction using this number. The
bottom detection from beam to beam is therefore based on the results
from the previous beams. Increasing this window size allows more
samples to be included in the detection process but also can introduce
noise. Decreasing this window size too much will degrade performance
when the bottom is not flat.
Click the “Update” button to finalize changes.
5.3.3 Ocean Settings
The Ocean menu allows for the entry of various correction factors to compensate
for changing environmental conditions.
5.3.3.1
Change the Absorption Loss Value (Absorption)
This selection allows the operator to enter the amount of loss expected through
the ambient water medium. The range available is from 0 to 120 dB/km.
This value is used in conjunction with the Spreading Loss Coefficient to compute
the TVG curve as described in Change the Spreading Loss Coefficient
(Spreading).
SeaBat 7111 Operator’s Manual
Version 1.00
Page 32
March 13, 2007
SYSTEM OPERATION
5.3.3.2
Change the Spreading Loss Coefficient (Spreading)
This selection allows the operator to enter the amount of cylindrical and spherical
Spreading Loss that is expected through the ambient water medium. The range
available is from 0 to 60, with a recommended initial value of 30.
This coefficient value is used in conjunction with the Absorption Loss value to
compute the TVG curve applied to the returned signal.
5.3.3.3
Automatic Absorption Profile
In normal operation the 7KCentre receives a 1010 CTD profile record from the
PDS2000 (when in realtime mode). Upon receipt of this, the centre uses a
Francois-Garrison model to compute an absorption profile for use in the sonar.
The profile may be displayed by selecting the ABSORPTION button in the
OCEAN menu tab.

SYSTEM OPERATION
5.3.3.4
Set the Sound Velocity (Sound Velocity)
The “Sound Velocity” item allows for entry of the externally measured speed of
sound through the local water. This value is represented in meters per second,
and is used in Range display and Receiver Beam Steering.
The range allowed is from 1400 to 1600 m/sec. If the local sound velocity is not
known, RESON recommends a value of 1480 to 1500 m/sec for open sea areas
and 1425 m/sec for fresh water. See Figure 35 as a general reference for typical
surface sound velocity at different temperatures and salinity.
NOTE: In normal operation, the sound velocity is set by PDS2000 using a
7610 message (when in REALTIME mode). This can be confirmed by
moving the slider away from the current value. The 7610 message will
cause the slider to be automatically set to the incoming value.
5.3.4 Primary Display Settings
The Primary Display Settings tab allows the operator to customize some of the
visual attributes of the Sonar Image.

5.3.5 I/O Module Settings
The I/O Module Setup is the primary means of configuring data flow into the
SeaBat from RS-232 devices attached to the system (such as SVP and GPS).
Configuration is done through this interface which sets up the I/O Module
installed on the 7-P. The data acquired by the I/O module is routed to the SeaBat
in real time to allow for accurate time stamping and beam forming.
The main I/O module is accessible via the “I/O module” tab on the main 7K GUI.
The left hand pane of the tab indicates the selected driver and communications
protocol. To select a new driver, use the NEW button. This provides a dialogue
box within which the appropriate driver and communications parameters may be
selected.
• Device List: This window displays the current list of devices.
• New: Create a new I/O device.
• Edit: Edit an existing I/O device.
• Remove: Delete an I/O device from the list.

March 13, 2007
SYSTEM OPERATION
• Device Status Display: Shows the status of the corresponding device
in the Device List window.
• QC: Launch the I/O Module Monitor.
NOTE: Accuracy of the bathymetric data depends entirely on a valid time
sync and SVP input from this module, unless another solution such as
PDS2000 is being used to perform this function. In the absence of time
sync, a software time stamp is employed, however this will usually result
in poor data quality since the time stamp is applied AFTER the last sample
is received. In the absence of SVP input, the input from the SeaBat7k
Ocean Settings Page is used instead.
The EDIT button uses the same dialogue box to edit settings. The I/O module
may be monitored by pressing the QC button. This enables the monitor window
which shows incoming messages.

SYSTEM OPERATION
The device page shows the port settings, names of the selected driver, raw data
messages and decoded values of the incoming data and a status indicator. Once
configured by the 7k User Interface and running and receiving data, messages
will begin to appear in the "Messages" window.
The status indicator shows "OK" in green when the data flow is normal. When a
problem occurs in the data flow (for example, when serial cable is disconnected),
the status indicator will change to red and will show the new status. When the
data flow has been recovered, the status will return to OK again.
The output page shows the 7k messages that are being sent to the 7kCenter.
For example, when an external clock and a sound velocity device are connected
and generating data, the output page will show 7400 messages (external clock).
NOTE: The I/O module pages only monitors its operation. All user input
(creating or changing the configuration) is done using the 7k user interface
(on the ‘I/O Module Setup’ page).
The I/O Module automatically saves configuration information and loads
the last settings upon restart.
