CHAPTER 1:OVERVIEW
The HydroChart 5000 Sonar System is a portable, high speed hydrographic survey
system which has the ability to simultaneously collect IHO-quality bathymetry and
co-registered, high resolution multibeam side scan sonar data.
1.1Equipment
The HydroChart 5000 Sonar System equipment consists of an instrumented Sonar
Head Unit, a Transceiver and Processing Unit (TPU) and a SonarPro Workstation,
along with a deck cable and various interconnect cables.
1.1.1Sonar Head Unit
The Sonar Head unit has all of the necessary electronics and acoustic
instrumentation to perform all of the sonar data acquisition and processing prior to
digital transmission to the TPU. Processing includes transmit and receive
functions, time varied gain (TVG) amplification, digitalization, and multiplexing
of the sonar uplink data. Timing and sonar data are bidirectionally multiplexed on
a single conductor coaxial cable, and the use of a low noise preamplifier design
ensures maximum range performance. The Sonar Head Unit has a flange assembly
which easily mates with typical customer provided over-the-side mount pole or
ram configurations. A jumper cable connects from the sonar electronics in the
Sonar Head Unit to the deck cable, and the deck cable connects to the TPU to
provide the electrical power and data connections.
1-1
1.1.2TPU
The TPU is housed in a 19-inch rack mountable 2U chassis and connects to the
Sonar Head Unit directly using a deck cable. The TPU receives and demultiplexes
the sonar and sensor data from the Sonar Head Unit and transfers the data to the
SonarPro Workstation over an Ethernet connection. The TPU can also input
standard National Marine Electronics Association (NMEA) 0183 message
sentence formats from a connected GPS, and a 1 PPS input is provided which
inputs 1 PPS (one pulse per second) signals from the GPS. This signal is used in
conjunction with a NMEA $ZDA message input to add an accurate time stamp to
the data. The TPU provides power and downlink commands to the Sonar Head
Unit by combining 200 VDC with FSK control signals for transmission over the
coaxial conductor in the tow cable. In addition, the TPU initiates each ping cycle
to the side scan sonar and provides a trigger signal simultaneously with the
responder trigger generated in the Sonar Head Unit for use with an acoustic
positioning system.
1-2CHAPTER 1Overview
1.1.3SonarPro Workstation
The SonarPro Workstation is an industrial grade Intel Pentium Dual Core
based computer housed in a 19-inch rack mountable 2U chassis that inputs
processed and time tagged sonar and sensor data from the TPU over an Ethernet
10/100/1000baseT connection. A SATA hard drive is included with the Microsoft
Windows 7 operating system and SonarPro installed. SonarPro is a comprehensive
Windows based software program that provides multiple displays of real-time or
saved sonar and sensor data and Sonar Head Unit status. SonarPro also allows you
to record all acquired sonar and sensor data. The SonarPro Workstation also
includes a high resolution 27-inch 2560 x 1440 monitor, a keyboard and a mouse.

The TPU is rack mountable in a standard 48.26 cm (19 inch) rack and contains
electronics for receiving sonar data, downlink multiplexing of control signals
to the Sonar Head Unit, and uplink demultiplexing of sonar and auxiliary
sensor signals.
SonarPro Workstation. The SonarPro Workstation is shown in Figure 1-1.
Most operator functions are accomplished through the use of the SonarPro
Workstation which supports the PC based Windows operating system and runs
SonarPro. SonarPro provides the operator interface to the HydroChart 5000
Sonar System. SonarPro is a comprehensive software package developed to
support survey planning; data visualization and quality control; target
management and data recording; and playback. SonarPro also performs the
side scan and bathymetry data processing. Data can be logged in SDF, GSF or
XYZ format. These formats are supported by most third party post-processing
software applications. In addition to processed data, raw stave data can be
logged together with all motion, navigation, and heading and sound velocity
data. This permits reprocessing of both side scan and bathymetry data in a
post-processing environment. For more information on the computer, refer to
the manufacturer's manual.

1.5Technical Description
The HydroChart 5000 Sonar System is a multiple swath forming, frequency
modulated (FM) chirp side looking sonar that provides high speed, high resolution,
extended range imagery and bathymetry. The two primary drawbacks of
conventional side-looking sonars, along-track resolution and towing speed
limitation, have been addressed by simultaneously forming multiple dynamically
focused beams per side, per ping. This allows greater side scan survey speeds
without the usual loss of bottom coverage while maintaining high resolution. In
addition, the formed swaths are focused dynamically with across-track range,
thereby offering an inherently improved along-track resolution over unfocused
systems. The interferometric bathymetry (also referred to as Phase Differencing)
component of the HydroChart 5000 Sonar System is not a multibeam sonar and
requires that speed and range settings be considered when operating the system for
100% bottom coverage.
1.5.1Sonar Head Unit
The Sonar Head Unit consists of the sonar arrays together with the sonar
electronics in a lightweight frame assembly. The sonar electronics, which is
contained inside a waterproof housing, includes transmitters, receivers and digital
circuits that combine time-synchronized complex stave samples, ping trigger
timing and optional time-synchronized motion data from the vessel’s sensors. An
altimeter is included, and the system accommodates an optional sound velocity
sensor or a CTD. For hull mount configurations, the electronics bottle is located
inside the vessel’s hull, and an optional transducer mounting bracket is required.
The two transducer arrays are each composed of 12 piezoelectric ceramic
1-6CHAPTER 1Overview
sub-arrays and three bathymetry sub-arrays that operate as receive elements. There
is also a separate transmit line array included that projects acoustic energy to the
seabed.
NOTE The transducers are side specific and are not interchangeable.
The Sonar Head Unit sonar electronics includes a T ransmitter board, two Receiver
boards and a Multiplexer board. A block diagram of the Sonar Head Unit is shown
in Figure 1-3.
Transmitter board. The Transmitter board produces a transmit pulse, at the
start of a swath, that ensonifies the sea floor over a defined footprint. The
Transmitter board is composed of two individual transmitting channels, one
connected to the port array and the other connected to the starboard array. The
transmitters operate at a center frequency of 455 kHz and support both CW and
chirp waveform transmission. The Transmitter board also contains transmit
and receive circuitry for the altimeter.
Receiver boards. The Receiver boards process the backscatter information by
applying fixed gain, time varied gain (TVG) and frequency filtering to the
input voltage signals received from the individual sub-arrays in the transducer
arrays. There are two Receiver boards, one for the port array and one for the
starboard array. Each of the receiver channels is bandpass filtered with tightly
matched filters providing a -3dB bandwidth of 20 kHz, centered at 455 kHz.
The filtered signal is then output to the Multiplexer board for sampling.
Multiplexer board. The Multiplexer board digitizes the signals from each of
the transducer sub-array channels along with the signals from the sensors,
encodes the data, and transmits a high baud rate digital data stream to the TPU
over the deck cable. The Multiplexer board also receives the trigger signal and
command messages which instruct the T ransmitter board to fire the arrays and
configure aspects of the sonar operation. In addition, the Multiplexer board
functions as a motherboard for the other boards providing the connections and
distributing power . The Multiplexer board uses a proprietary sampling scheme
that preserves the phase of the individual channel signals, but only requires a
single A/D converter, thereby reducing cost and power consumption while
eliminating the phase mismatch between converters of alternate dual converter
schemes. The output of the A/D is input to the data encoder and converted to
serial data for subsequent transmission over the deck cable. A full duplex
hybrid allows data transmission up the cable while simultaneously receiving
the FSK trigger signals and power. The downlink signals are input to FSK
demodulators, and the baseband outputs are routed to the Transmitter board,
indicating when to fire the main array, and to a micro controller that handles
the sonar configuration.

crate and inspect the Sonar Head Unit for damage. If there is any damage or if any
items are missing, immediately contact Klein Marine Systems, Inc. or your KMS
sales representative. Record the serial number of the Sonar Head Unit. The serial
number can be found on the aft end of Sonar Head Unit mounting flange opposite
the FWD label.
3.2Locating the Topside System Components
The TPU and the SonarPro Workstation should be located in an area that is
protected from weather and spray and where the temperatures are consistently
between 0°C and 35°C (32°F and 95°F). The location should also be near the
Sonar Head Unit or be adequately equipped with devices for communicating with
launch personnel. If separately mounting components in a 19-inch rack, ensure
that the rack is properly secured and that there is ample room behind it for
connecting the cables. A thick layer of foam should also be placed under the rack
for shock isolation, and the back of the rack should be left open for proper air flow .
Support the units inside the rack using appropriate mounting brackets, shelves or
slides as needed and secure the front panels to the front of the rack where possible
using standard 19-inch rack front panel mounting hardware.
3.3Power Requirements
The TPU and the SonarPro Workstation require 100–125 or 200–250 VAC,
50–60 Hz power to operate. The HydroChart 5000 Sonar System is designed to
protect against over and under voltage and transient spikes. However, it is always
best to check the power source carefully using a voltmeter or oscilloscope before
operating the equipment.
CAUTION Application of improper AC power may damage the
HydroChart 5000 Sonar System. Do not turn the equipment on until the
supply voltage and frequency have been checked.
HydroChart 5000 Sonar Operations and Maintenance ManualP/N 11210080, Rev. 02
Sonar Head Unit Installation3-3
Since a variety of power connectors are in use throughout the world, it may be
necessary to use an adapter or to cut off the US-type plug on the AC power cable
and re-terminate it with a new plug. Should this modification be required, the
wires should be connected in accordance with Table 3-1.

3.3.1Grounding
It is important that the HydroChart 5000 Sonar System be well grounded to
minimize potential hazards to the operator and electrical interference from other
equipment. A good ground for the system is a low impedance, well conducted path
to sea water. Always check the quality of the electrical ground by verifying that the
AC power source ground has no voltage potential with respect to the vessel hull.
3.3.2TPU and SonarPro Workstation Circuit Breakers
The main AC power input line is protected by a switch/circuit breaker in both the
TPU and the SonarPro Workstation. The one on the TPU is located on the front
panel on the far right as shown in Figure 3-6 on page 3-12. The one on the
SonarPro Workstation is located on the pack panel just to the right of the AC
INPUT connector as shown in Figure 3-5 on page 3-9. To reset a switch/circuit
breaker, switch it to ON.
3.4Sonar Head Unit Installation
When installing the Sonar Head Unit, lightly grease the male pins of the
waterproof connectors before connecting them. The silicone grease serves an
important lubricating and corrosion protection function. Use a high quality,
nonconducting grease such as Dow Corning DC-4. Before connecting the deck
cable, make a general inspection of the Sonar Head Unit. Check that the fasteners
holding the Sonar Head Unit to the mounting platform are tight. Check that all
cables running from the Sonar Head Unit are secured. A safety cable should also
be attached to the Sonar Head Unit in the event that it breaks free.

Bathymetric System Calibration and Patch Test3-15
CAUTION Serious damage to the Sonar Head Unit electronics may occur
if the Sonar Head Unit is operated on deck for periods longer than fifteen
minutes. Between periods of operation, let the sonar cool for fifteen
minutes. In high temperature climates, protect the Sonar Head Unit from direct
exposure to the sun prior to and during operation.
6. Start SonarPro.
7. Verify that the Sonar Head Unit is transmitting by viewing the output pulse in the
Scan window . In addition, and if available, v erify that position, motion and sound
velocity data are being displayed in the Information window.
8. Select the 150-meter range and perform a rub test on the port and starboard
transducers by vigorously rubbing each transducer , one at a time, while ob serving
the Sonar Viewer window.
The signal amplitudes should be prominent whenever the transducers are
rubbed.
9. Exit SonarPro.
10. Turn off the SonarPro W orks tation and the TPU.
3.10Bathymetric System Calibration and Patch Test
For new installations it is recommended that a patch test be performed to quantify
any residual biases in the installation which could affect the accuracy of the
bathymetry data. The tests use a series of reciprocal lines run at different speeds,
depths and bottom slopes as inputs to compute the following residual biases:
• Positioning/Latency error
• Pitch bias
• Yaw bias
• Roll bias
For the tests outlined below, all acquired data can be batch processed using the
Klein Batch Processing GUI application and subsequently analyzed using a
third-party application, such as Caris and Hypack. For details regarding the data
interface/conversion, see the Help file in the Klein Batch Processing GUI
application. The tests are listed in the recommended order in which they should be
processed. For example, latency should be processed before pitch, which is
followed by yaw, and then roll. This will eliminate the effects of uncorrected errors
on the other axis.
3-16CHAPTER 3Preparation for Deployment
Following are a few available references containing information about the
calculation procedures for these offsets and errors:
• "Field Procedures for the Calibration of Shallow Water Multibeam
Echo Sounding Systems," Andre G odin, Canadian Hydrographic
Service, Halifax, Nova Scotia, Canada, 1996.
• "US Army Corps of Engineers, Engineer Manual EM-1110-2-1003,"
Hydrographic Surveying, Jan-02.
3.10.1 Static Position Offsets
It is necessary to first measure the static position offsets between the Sonar Head
Unit, the position sensor and the motion reference unit, relative to some reference.
These measurements will provide the necessary data for applying lever-arm
corrections to the final bathymetric solution. SonarPro provides an interface to
record these offsets in the Ship Geometry Setup dialog box such that they can be
recorded along with the sonar data to provide real time correction during data
acquisition. See the "SonarPro User Manual" (P/N 11210079) for more
information.
3.10.2 Latency Error
This test will provide a measurement of the latency error, or time, in the overall
system, which manifests itself as a position error in the processed data. It is
recommended that lines be run in the same direction and at different speeds over
an area with a prominent bathymetric feature. This will offset any effects due to
pitch bias. The greater the speed difference the more accurate the measurement.
The latency can be derived by measuring the along-track displacement of depth
measurements over the bottom feature.
3.10.3 Pitch Bias Test
Pitch bias is similar to roll bias, except that pitch error lies in the along-ship’s
fore-aft axis. This error occurs when the motion reference unit and the transducer
arrays are not pitch-aligned; that is, they are not mounted on the same fore-aft axis.
The resulting error changes the apparent location of a feature and is proportional to
water depth. In addition, along-track displacement error increases as water depth
increases. For the pitch bias test the survey vessel should run reciprocal lines on a
sloped bottom, preferably on the order of 10–20 degrees, for 200–300 meters. It
may be possible to use a channel feature instead of a long sloping bottom. Speed
for the test should be equal for both lines.

Bathymetric System Calibration and Patch Test3-17
3.10.4 Yaw Bias Test
For the yaw bias test the objective is to determine azimuth offset error between the
motion reference unit and the sonar arrays. For this test it is recommended that the
survey vessel run two pairs of adjacent lines on reciprocal headings over a flat
bottom with a prominent bathymetric feature, such as the edge of a ship channel.
The adjacent lines should overlap by 10–20%. In computing the azimuth offset, the
data from the reciprocal lines can be used to remove any roll offset. The parallel
lines run in a direction normal to the bottom feature can be used to compute the
azimuth offset using several measurements of the across-track displacement.
3.10.5 Roll Bias Test
This test determines the athwartship alignment error between the transducer arrays
and the motion reference unit as well as any additional roll axis bias error in the
motion reference unit. The result is a roll correction which can be used during post
processing operations. For the roll bias test you should choose a relatively flat area
of the sea bottom and run at least two reciprocal lines 200–300 meters in length at
equal speeds in both directions.
CHAPTER 4:EQUIPMENT MAINTENANCE
This chapter provides instructions for equipment maintenance and includes guides
for taking care of the HydroChart 5000 Sonar System on a daily, weekly, and long
term basis. In addition, instructions are provided for disassembling and
reassembling the Sonar Head Unit.
4.1Maintenance General Comments
Equipment used at sea is subjected to severe environmental and handling
conditions. While the HydroChart 5000 Sonar System is designed to operate in
such conditions, a certain amount of routine maintenance is necessary to ensure
trouble free, long term operation.
Keep a maintenance log. This provides assistance in tracking what has or has not
been done with the system. A log is useful when tracking problems, if they do
occur, and is especially important if more than one TPU, SonarPro Workstation, or
Sonar Head Unit is used in a large survey operation. Inventory the system and
related spares and accessories carefully. Record the serial numbers of the major
components, such as the TPU, the SonarPro Workstation, and the Sonar Head Unit.
Store the shipping boxes in a safe place so they can be reused when needed. A
small amount of regular maintenance and care makes the critical difference in a
successful field operation. The following pages contain the recommended routine
checking and maintenance schedules for a daily, weekly, and long term basis.
4-1
4.2Maintenance Checklists
4.2.1Daily Maintenance Checklist
Perform the following maintenance steps at the end of each day’s operation:
1. Turn off the power to the TPU and to the SonarPro Workstation.
2. Verify that all cables and connectors are secure and tightened.
3. If fresh water is available, wash down the Sonar Head Unit. Cover it while not in
use to protect against salt water spray and to minimize corrosion.
4-2CHAPTER 4Equipment Maintenance
4. Keep the deck cable plugged into the Sonar Head Unit, or use dummy plugs to
keep the connectors from exposure to the salt atmosphere. Remember to put a
thin film of silicone grease, such as Dow-Corning 4, on the rubber portion of the
underwater connector every time the Sonar Head Unit is disconnected. Avoid
getting too much grease on the metal pins of the connector; a very light coating is
sufficient.
5. Check that all of the screws on the Sonar Head Unit are tight.
4.2.2Weekly Maintenance Checklist
Perform the following maintenance steps at the end of each week’s operation:
1. Turn off the power to the TPU and to the SonarPro Workstation.
2. Check all cables for abrasion and damage. If any wear spots are noticed, clean
them with fresh water, dry them, and wrap them carefully with electrical tape,
such as Scotch #88 or #33. If there is wear or fraying in any of the cables in an
area subject to high tension, repair or replace the cable.
3. Inspect and clean the system connectors.
4. Inspect the Sonar Head Unit for signs of corrosion or other damage.
5. Check the underwater connectors on the Sonar Head Unit. The contacts should be
clean and shiny . Contacts may be cleaned with a rubber pencil eraser or very fine
emery paper.
4.2.3Long Term Maintenance Checklist
Perform the following maintenance steps at six month intervals, or more
frequently when continued long term usage is occurring.
1. Turn off the power to the TPU and to the SonarPro Workstation.
2. Thoroughly clean the TPU and cables. Clean the top and outside surfaces of the
TPU using a cloth dampened with fresh water . Use a small amount of deterg ent if
necessary. Do not let dirt and salt deposits accumulate on the TPU cabinet.
3. Replace the AC fuses in the TPU as preventive maintenance. Fuses will
sometimes fatigue after long term use or operation.
4. Check that all the connectors on the Sonar Head Unit are firmly seated. Make
sure that all the cables are free from cuts or abrasion.
5. Follow the instructions in the manufacturer's manual for any necessary cleaning
and maintenance of the
HydroChart 5000 Sonar Operations and Maintenance ManualP/N 11210080, Rev. 02

CONFIGURATIONAND
TROUBLESHOOTING
Included in this appendix are basic setup and configuration instructions along with
other information useful for setting up and maintaining the HydroChart 5000
Sonar System. In addition, information is provided which can be helpful for
system troubleshooting should problems occur, including instructions on how to
verify operation of hardware components and transducers.
WARNING Klein Marine Systems recommends all troubleshooting be
done by a trained technician. Some circuits in the Transceiver and
Processing Unit (TPU) have voltages as high as 240 volts, and some
circuits in the sonar Sonar Head Unit have 1500 volts. You should familiarize yourself
with the location of these voltages before you attempt any troubleshooting. Failure to
observe these warnings could result in injuries to personnel.
A-1
CAUTION Serious damage to the sonar electronics may occur if the Sonar
Head Unit is operated out of the water for periods longer than 15 minutes.
Let the sonar cool 15 minutes or longer between operations. Protect the
Sonar Head Unit from dir ect exposure to the sun prior to and during operation in high
temperature climates.
CAUTION The depth rating on the transducers is 200 meters (656 feet).
Operations at depths greater than 200 meters may damage the tra nsd ucers.
A-2APPENDIX A General Setup, Configuration and Troubleshooting
A.1Basic System Requirements
Although we suggest that you get the fastest available computer at the time of
purchase, it is recommended that you use the following minimum PC system.
• 2.0 GHz Intel Core 2 Duo Processor
• 1 GB RAM
• 80 GB hard drive
• 8 MB video card
• 100BaseT Ethernet card, such as a 3Com 3C905
• Windows XP or Windows 7
• Power backup module
When running the PC system it is important to make sure that you leave at least
500 MB of free disk space for temporary system disk swap files.
A.2Basic System Setup
Refer to Figure A-1 for the basic system setup information. Also refer to
“CHAPTER 3: Preparation for Deployment,” for detailed connection information.
A.3Installing SonarPro
Insert the SonarPro CD into your CD-ROM drive, and then locate the SonarPro
Installation.pdf file in the Documentation folder. Double-click this file to open it.

The Sonar Head Unit is shown in Figure A-2.
Figure A-2: Sonar Head Unit
A.4.1Checking the Telemetry Link to the Sonar Head Unit
Turn the TPU. The SYS READY indicator should flash. Then after approximately
1 minute, the T/F POWER indicator should turn on, the SYS READY indicator
should stop flashing and remain on, and the STATUS TRIGGER indicator should
begin flashing at the ping rate of the sonar.
A.4.2Checking the Transmitters before Deployment
Each transducer assembly contains separate transmitter and receiver arrays. Each
transmitter array (one port, one starboard) is driven by one transmitter circuit.
NOTE The transmit transducers are electrically shielded. For this reason,
it is difficult to localize the source (port or starboard) of the waveform
picked up by the probe. To distinguish between the port and starboard
transmitters, ground the oscilloscope probe to the Sonar Head Unit skin while
searching near the middle of each transducer assembly for the signal.
HydroChart 5000 Sonar Operations and Maintenance ManualP/N 11210080, Rev. 02
Sonar Head UnitA-5
To verify that the transmitters are working, run an oscilloscope probe with the
scope tip in place along the transducer and see the transmit waveform as in the
image in Figure A-3. If there is a problem with a transmitter, it will show up as a
very weak transmit waveform.
Figure A-3: Transmit Waveform
A.4.3Checking the Receivers before Deployment
With the Sonar Head Unit running on deck, start SonarPro. Allow the TVG gain to
adjust, and then rub the transducers firmly , one trans ducer at a time. This is the rub
test. The image in the Sonar Viewer window should look something like that in
Figure A-4.
A.4.4Setting up for Testing the Electronics
Remove the Sonar Head Unit electronics as described in “Disassembling and
Reassembling the Sonar Head Unit” on page 4-3 and place the electronics in a
position so that you can reconnect the transducers.
A.4.5Checking the Multiplexer Board
The Multiplexer board performs the following functions:
• Receives the 200 VDC and telemetry from the surface and
separates out the telemetry from the 200 VDC.
• Routes the 200 VDC to the power supply, and then receives the
converted ±12 VDC.
• Routes the 200 VDC to the Transmitter boards.
A-6APPENDIX A General Setup, Configuration and Troubleshooting
Figure A-4: Image in Sonar Viewer Window During a Rub Test
• Generates ±5 VDC, +3.3 VDC, and +28 VDC.
• Generates the time varied gain (TVG) curves for the received
sonar signals from the transducers.
• Multiplexes all the data channels and transmits the telemetry back
to the surface.
• Provides cable uplink and downlink interface, as well as electrical
output for external fiber uplink.
200 VDC is indicated by bright orange LED D40. The voltage can be checked at
JP8. The +5 volts is generated by a switching regulator and indicated by green
LED D37. The voltage can be checked at L37. TPGND1 provides a ground
reference. A second switching regulator generates -5 VDC, indicated by green
LED D38, and measurable at L30. A third switching regulator generates +3.3
VDC, indicated by green LED D39 and measurable at L26. (Be sure to measure at
the output side of L26.) +28 VDC is generated by a fourth switching regulator,
which can be measured at TP25. Use TPGND8 for ground reference. A linear
regulator generates 2.5 VDC from the 3.3 VDC source. This is indicated by green

LED D9, and measurable at TP9. TPGND1 can be used for ground reference. A
second linear regulator generates 1.2 VDC from the 3.3 VDC source. This is
indicated by green LED D11, and can be measured at TP10.
Some useful test points and waveforms are shown in Figure A-5.
Figure A-5: Multiplexer Board Waveforms
A.4.6Checking the Transmitter Board
By probing on the Transmitter board you can check that the transmitters are
working. Probe each transmitter output connector (J5-1, 2; J6-1, 2) to view the two
transmitter outputs. These are floating differential output pairs, so the signal levels
at pin 1 and 2 may be unequal. But all four pins should show transmitter outputs
similar to that shown in Figure A -6, and you should see a scope trace similar to the
one shown in the figure. You can select different pulse lengths on the System 5000
Control tab of the Sonar Interface dialog box. Note that pulse lengths of 2 ms and
greater are generated at a lower amplitude than shorter pulse lengths. The altimeter
transmitter can be checked at J7-1.
