Series 5000 V2 Sonar System Operations and Maintenance Manual P/N 11214512, Rev. 04

WARNING

Klein Marine Systems, Inc. recommends all troubleshooting be
done by a trained technician. Some circuits in the Sonar
Transceiver and Processing Unit have voltages as high as 240 volts,
and some circuits in the sonar towfish 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.

CAUTION

Serious damage to the sonar electronics may occur if the sonar
towfish 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 towfish from direct exposure to the
sun prior to and during operation in high temperature climates.

iii

CAUTION

The depth rating on the transducers for the Series 5000 V2 Sonar
System is 500 meters (1640 feet). Operations at depths greater than
500 meters may damage the transducers. For a Series 5000 V2
Sonar System with bathymetry option, the depth rating is
200 meters (656 feet). Operations at depths greater than 200 meters
may damage the transducers.

Series 5000 V2 Sonar System Operations and Maintenance Manual P/N 11214512, Rev. 04

CHAPTER 1: OVERVIEW

The Series 5000 V2 Sonar System is a very high resolution, multibeam long range
sonar system that is ideally suited for surface mine counter measure applications
and hydrographic, geophysical, pipeline, and offshore surveys. 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 towing speeds
without the usual loss of bottom coverage while maintaining high resolution. The
system employs operator selectable chirp and continuous wave (CW) technologies
which, when coupled with KMS proprietary display algorithms, provides
extraordinary sea floor images. In addition, rugged construction, low weight and
simple setup enables operation from large or small vessels.

1.1 Main Features

1-1

The Series 5000 V2 Sonar System provides the following main features:

• High speed, high resolution, multibeam side scan sonar.

• 14-bit digital multiplexer for transmission of sonar and control
data over a single coaxial cable.

• PC based operation using SonarPro and the Windows operating
system.

• Operation at 455 kHz for ranges up to 150 meters.

• Flexible and expandable system configurations.

• Chirp and CW operating modes.

• 500-meter operating depth (200-meter with bathymetry option).

• Operation with up to 800 meters of coaxial 0.680-inch diameter
armored tow cable.

• Heading, pitch, roll and pressure sensors.

• Optional interfaces for a responder, acoustic positioning system
yaw rate sensor, and altimeter.

• Small, lightweight and simple to operate and maintain.

1-2 CHAPTER 1 Overview

1.2 System Components

The main components of the Series 5000 V2 Sonar System are the towfish and the
topside system. The towfish is the underwater component and is towed with an
armored coaxial tow cable up to 800 meters in length. The topside system provides
the power source for the towfish and receives, stores and processes data acquired
by the towfish. The towfish connects to the topside system using an optionally
supplied winch with slip rings and an armored coaxial tow cable. A terminated,
light weight deck cable is optionally supplied for connecting to the winch or for
connecting directly to the towfish for testing. The topside system is composed of
two separate main components:

• Transceiver and Processing Unit (TPU)

• SonarPro Workstation

In addition, a K-Wing I or K-Wing II Depressor can be installed on the towfish
which enables a greater towing depth with less cable deployed.

1.2.1 Towfish

The towfish, which is shown in Figure 1-1, consists of a negatively buoyant
stainless steel towfish housing with attached port and starboard sonar transducer
arrays, an altimeter, a nose cone, and a tail cone with stabilizing fins. Inside the
towfish housing is a pressure housing containing the sonar electronics, a downlink
demultiplexer for control signals, an uplink multiplexer for sonar and sensor data,
a transmitter board for transmit pulses, receiver boards for receiving signals, and
the compass, pitch/roll and pressure sensors. The downlink control signals and the
uplink sonar and sensor data are multiplexed onto a single conductor coaxial tow
cable. An electro-mechanical termination is provided on the towfish end of the tow
cable, where a shackle provides a strong, reliable mechanical termination to the
towfish tow bracket, and an underwater connector connects to a jumper cable on
the towfish. Four carrying handles, two forward and two aft, are included for
lifting and transporting the towfish. The installed safety cable minimizes the
chances of losing the towfish should it collide with an obstruction.

1.2.2 TPU

The TPU is housed in a 19-inch rack mountable 2U chassis and connects to the
towfish directly using an optional coaxial tow cable, or to an optionally supplied
winch using an optionally supplied deck cable, where the winch connects to the
towfish using a tow cable. The deck cable can also be used to connect the TPU
directly to the towfish for testing. The TPU receives and demultiplexes the sonar
and sensor data from the towfish and transfers the data to the SonarPro
Workstation over an Ethernet connection. The TPU provides power and downlink

commands to the towfish 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 towfish for use with an
acoustic positioning system. 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.

1.2.3 SonarPro Workstation

The SonarPro Workstation is an industrial grade 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 100baseT connection. A SATA
hard drive is included with the W indows operating system and SonarPro installed.
SonarPro is a comprehensive Windows based software program that provides
multiple displays of real-time or previously recorded sonar and sensor data.
SonarPro also allows you to record all acquired sonar and sensor data. The
SonarPro Workstation includes a high resolution 27-inch 2560 x 1440 monitor, a
keyboard and a mouse.

CHAPTER 3: PREPARATION FOR USE

This chapter provides instructions for unpacking the Series 5000 V2 Sonar
System, connecting its components and a navigation system, and testing the
system both on deck and at sea. Descriptions of all the connections and the
controls and indicators for all the system components are also included.

3.1 Unpacking and Inspection

The towfish and the topside system components, including associated cables and
documentation, are shipped in multiple shipping cases. Unpack all of the cases and
verify that all of the items listed on the packing list have been received. If any
items are damaged or missing, immediately contact Klein Marine Systems, Inc. or
your KMS sales representative. In addition, record the serial numbers for the
towfish, the TPU and the SonarPro Workstation. The towfish serial number can be
found on the towfish tow bracket. Refer to Figure 1-1 on page 1-3 for the location
of the tow bracket. The serial numbers for the TPU and the SonarPro Workstation
or laptop can be found on the rear panel of each.

3-1

3.2 Locating 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
towfish launch point 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.

3.3 Power Requirements

The TPU and the SonarPro Workstation require 100–125 or 200–250 VAC,
50–60 Hz power to operate. The Series 5000 V2 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.

3-2 CHAPTER 3 Preparation for Use

CAUTION Application of improper AC power may damage the Series

5000 V2 Sonar System. Do not turn the equipment on until the supply
voltage and frequency have been checked.

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.

Blue or white Neutral
Brown or black Hot

3.3.1 Grounding

It is important that the Series 5000 V2 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.

3.3.2 TPU 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 3-3 on page 3-12. The one on the
SonarPro Workstation is located on the back panel just to the right of the AC
INPUT connector as shown in Figure 3-2 on page 3-9. To reset a switch/circuit
breaker, switch it to ON.

3.4 Towfish Setup

Before connecting the tow cable, make a general inspection of the towfish. Check
that the retaining screws securing the towfish nose cone and tail section assemblies
are tight. Check the tail fins and tow bracket assembly to be sure the retaining
screws and bolts are secure. Also verify that the tail fins are straight and true.

3.4.1 Connecting the Tow Cable

WARNING Before connecting the tow cable, verify that the power to the

TPU is turned off. Also disconnect the TPU power cable from the power
source. Failure to follow this practice may result in personal injury or

damage to the towfish or the TPU electronics, or to both.

SHOCK HAZARD Do not connect or disconnect the tow cable from the

towfish or the TPU when power is on. Failure to follow this practice may
result in personal injury and will damage the towfish or the TPU

electronics, or both.

To connect the tow cable:

1. Remove the retaining ring from the beveled end of the tow pin and withdraw

the pin from the tow bracket.

2. Align the tow shackle mounting hole with the upper mounting hole of the tow

bracket, and then insert the beveled end of the tow pin through the holes in the
tow cable shackle and the bracket and secure the pin with the retaining ring.

3. Remove the dummy plug from the connector on the towfish end of the tow

cable and from the towfish jumper cable.

CAUTION Always avoid putting excessive silicon grease on the Subcon

male pins. Apply a light coat of grease, and never put gr ease into the female
connectors.

4. Apply a thin film of silicone grease to the pins of the male connector. Use a

high quality, nonconducting grease such as Dow Corning DC-4.

CAUTION When connecting or disconnecting the electrical connection, do

not bend it back and forth. Use straight up action. Pull on the connector,
not the cable.

5. Align the male and female connectors and press the connectors together

firmly . If neces sary, use a slight side to side rocking motion while pressing on
the connector, but do not bend the pins. When properly inserted there should
be no gap between the surfaces of the two connectors.

3-4 CHAPTER 3 Preparation for Use

6. Attach the shackle end of the safety cable to the bail grip loop on the tow cable

near the tow cable shackle, and the clevis pin end to the safety cable tab on the
top of the towfish near the tail. Refer to Figure 1-1 on page 1-3 for the location
of the safety cable tab. The safety cable must be taut enough so that drag, or
the likelihood of snagging, is not increased, but loose enough so that it does
not interfere with the functioning of the tow shackle.

NOTE The tow cable and not the safety cable must take up the strain of the

tow load.

7. If not already secured, use cable ties (7.5 x 0.185 in.), which are included in

the towfish spares kit, to fasten the safety cable to the cable hold-down clips
on the top of the towfish housing. Place a cable tie through the shackle pin
hole and wrap around the shackle pin to prevent the shackle from loosening.
Use electrical tape every 30 cm (12 in.) to secure the safety cable to the tow
cable starting at the top of the tow shackle and up the bail grip loop. Move the
tow shackle forward and backward to check for smooth operation.

3.4.2 Connecting the Tow Cable with the Optional K-Wing Depressor

The shackle on the tow cable connects mechanically to the towfish K-Wing
depressor tow bracket using a tow pin. The depressor connects mechanically to the
towfish. The waterproof connector on the towfish jumper cable connects to the
waterproof connector on the tow cable. The towfish mechanical and electrical
connection procedure is as follows:

1. Remove the retaining ring from the beveled end of the tow pin, withdraw the

pin from the tow bracket and set it aside. Remove the two bolts and tow
brackets from the welded-on six-hole towing flange. Take note of the location
of the tow brackets for future reference.

2. Position the K-Wing depressor over the towing flange in the same location as

where the tow brackets were previously connected. Secure the depressor to the
towing flange with the fasteners provided.

3. Align the tow shackle mounting hole with the mounting hole of the K-Wing

shackle on the tow depressor tow bracket. Insert the beveled end of the tow
pin through the holes in the tow cable shackle and the bracket, and secure the
tow pin with the retaining ring.

4. If the towfish was previously configured for towing without a depressor, it

will be necessary to extend the free length of the towfish 100-inch jumper
cable in order to reach the shackle connector. Do not extend more than is

Series 5000 V2 Sonar System Operations and Maintenance Manual P/N 11214512, Rev. 04

Towfish Setup 3-5

needed to make the connection and to provide free rotation of the tow shackle.
Remove the dummy plug from the connector on the end of the tow cable.
Apply a thin film of silicone grease to the pins of the connector. Do not over
grease. Align the male and female connectors, and press the connectors
together firmly. If necessary, use a slight side-to-side rocking motion while
pressing on the connector, but do not bend the pins. When properly inserted
there should be no gap between the surfaces of the two connectors.

5. Attach the shackle end of the safety cable to the bail grip loop on the tow cable

near the tow cable shackle, and the clevis pin end to the safety cable tab on the
top of the towfish near the tail. Refer to Figure 1-1 on page 1-3 for the location
of the safety cable tab. The safety cable must be taut enough so that drag, or
the likelihood of snagging, is not increased, but loose enough so that it does
not interfere with the functioning of the tow shackle.

NOTE The tow cable and not the safety cable must take up the strain of the

tow load.

6. If not already secured, use cable ties (7.5 x 0.185 in.), which are included in

the towfish spares kit, to fasten the safety cable to the cable hold-down clips
on the top of the towfish housing. Place a cable tie through the shackle pin
hole and wrap around the shackle pin to prevent the shackle from loosening.
Use electrical tape every 30 cm (12 in.) to secure the safety cable to the tow
cable starting at the top of the tow shackle and up the bail grip loop. Move the
tow shackle forward and backward to check for smooth operation.

3.4.3 Disconnecting the Tow Cable from the Towfish

If possible, it is best to keep the tow cable connected to the towfish while on deck.
If the tow cable is disconnected, however, it is very important that all the
connectors be properly maintained. Connectors must be kept clean and must
remain out of the way of traffic while on deck. Klein Marine Systems, Inc.
supplies dummy connectors which can be used to protect the underwater
connectors on the towfish and cable when they are not mated to each other.

WARNING Before disconnecting the tow cable, verify that the TPU is

turned off and that its power cord is disconnected. Failure to follow this

practice may result in personal injury or damage to the towfish or to the
TPU electronics, or to both. For the location of the power switches, refer to “Topside
System Controls and Indicators” on page 3-11.

3-6 CHAPTER 3 Preparation for Use

To disconnect the tow cable:

1. Verify that the TPU is switched off and that its power cord is disconnected.

2. Disconnect the safety cable from the bail grip loop. Remove the electrical tape

securing the safety cable to the tow cable. Cable ties fastening the safety cable
to the cable hold-down clips on the towfish housing may remain in place.

3. Separate the connectors by first loosening the locking sleeve. Then double

check that the TPU is off and grasp the body of the connector and gently pull
it out of the tow shackle connector. Do not pull on the wires to separate the
connectors. Always hold the body of the connector. After separating the
connectors, put a thin coating of silicone grease on the rubber section of the
connector pins.

4. Remove the retaining ring from the tow pin and withdraw the pin. Disengage

the tow cable shackle from the towfish or tow bracket. Replace the tow pin in
the hole in the tow bracket, and secure it with the retaining ring.

CHAPTER 4: MAINTENANCE AND

TROUBLESHOOTING

This chapter provides instructions on how to perform maintenance and
troubleshooting of the Series 5000 V2 Sonar System and includes guides for
taking care of the equipment on a daily, weekly, and long term basis. In addition,
instructions are provided on how to replace the fixed tail cone assembly and
remove, install and test the towfish electronics.

WARNING Klein Marine Systems, Inc. recommends all tr oublesh ooting be

done by a trained technician. Some circuits in the Sonar Transceiver and

Processing Unit have voltages as high as 240 volts, and some cir cuits in the
sonar towfish 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.

4-1

CAUTION Serious damage to the sonar electronics may occur if the sonar

towfish 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
towfish from direct exposure to the sun prior to and during operation in high
temperature climates.

4.1 General Maintenance Recommendations

Equipment used at sea is subjected to severe environmental and handling
conditions. While the Series 5000 V2 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
towfish is used in a large survey operation. Inventory the system, related spares
and accessories carefully. Record the serial numbers of the major components.
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.

4-2 CHAPTER 4 Maintenance and Troubleshooting

4.2 Maintenance Checklists

4.2.1 Daily 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 towfish and towing apparatus. Cover

them while not in use to protect against salt water spray and to minimize
corrosion.

4. Keep the tow cable plugged into the towfish, or use dummy plugs on the tow

cable and towfish 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 towfish 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 towfish are tight.

4.2.2 Weekly 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 plugs and jacks.

4. Inspect the towfish for signs of corrosion or other damage.

5. Check the underwater connectors on the towfish. The contacts should be clean

and shiny . Contacts may be cleaned with a rubber pencil eraser or very fine emery
paper.

4.2.3 Long 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.

Electronics” on page 4-7 and place the electronics in a position so that you can
reconnect the transducers. The towfish electronics is shown removed and ready for
servicing in Figure 4-12.

Figure 4-12: Towfish Electronics Ready for Servicing

4-10 CHAPTER 4 Maintenance and Troubleshooting

4.7.1 Checking the Multiplexer Board

The Multiplexer board is shown Figure 5-2 on page 5-3. When checking voltages,
unless otherwise noted, use TPGND1 as the ground reference. Reference
designations are printed on the board.

To check the Multiplexer board, do the following:

• Verify that 200 VDC is present on JP8 and that orange LED D40 is
illuminated.

• Verify that +5 VDC is present at L37 and that green LED D37 is
illuminated.

• Verify that -5 VDC is present at L30 and that green LED D38 is
illuminated.

• Verify that +3.3 VDC is present on the output side of L26 and that
green LED D39 is illuminated.

• Verify that +28 VDC is present at TP25. Use TPGND8 as the
ground reference.

• Verify that +2.5 VDC is present at TP9 and that green LED D9 is
illuminated. The +2.5 VDC is generated from the +3.3 VDC.

• Verify that +1.2 VDC is present at TP10 and that green LED D11
is illuminated. The +1.2 VDC is generated from the +3.3 VDC.

In addition, refer to Figure 4-14 for some applicable waveforms.

4.7.2 Checking 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 4-14, 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.

4.7.3 Checking the Receiver Boards

If your sonar image seems to be having problems on one side, this is an indication
that you may have a receiver problem. Try swapping the receiver boards and see if
the problem follows the board.

4.7.4 Checking the Sensors

Sensor readings can be read out directly in the Information window in SonarPro.
Move the towfish in pitch, roll and heading and check to see if the readings
change. If you have no sensor readings, check that the cable is properly plugged
into the sensor interface board at JP5. Also check that the cable is properly
connected at the compass board.

4.7.5 Calibrating the Optional Temperature Probe

The optional temperature probe adjustment is made on the Sensor Interface board.
With the towfish open, turn the towfish on, and let the system boot up. Start
SonarPro. With the towfish at ambient temperature, measure the ambient
temperature with an accurate thermometer. Set the potentiometer on the Sensor
Interface board, which is shown in Figure 4-15, to the current temperature. The
temperature can be viewed in the Information window in SonarPro.

Figure 4-15: The Sensor Interface Board

4.7.6 Calibrating the Compass

The compass is calibrated using the Compass Calibration Wizard in SonarPro. To
start the wizard, click Run Compass Calibration Wizard on the Towfish
Diagnostics tab of the Sonar Interface dialog box. Follow the instructions and play
the demonstration animation.

The compass calibration must be performed away from all magnetic and metal
sources, most likely off the ship. You enable the towfish compass calibration mode
and then rotate the towfish slowly 360 degrees in a circle (more than a minute). At
the same time you must pitch and roll the towfish beyond its 20 degree limits, we
suggest 45 degrees to be safe.

Series 5000 V2 Sonar System Operations and Maintenance Manual P/N 11214512, Rev. 04

Testing the Towfish Electronics 4-13

NOTE Excellent calibration results have been obtained by enabling the

compass calibration and towing the towfish in a series of three circles with
the boat.

NOTE If trying the method mentioned in the note above, survey the area

first making sure you have enough water to operate safely since the
transmitters are turned off.

The compass calibration can also be done by manually entering commands in the

Operator command area of the Towfish Diagnostics tab. After entering a

command, click Send Command to send the command to the towfish.
To calibrate the compass manually, enter the following commands in the order

shown.

$TM0: Turn off transducer transmitter.
$TA0: Turn off altimeter transmitter.

$Ch: Halt compass transmission.

$Cmpcal=d: Disables compass multi-point calibration mode.
$Ccc: Clears compass calibration table.
$Cmpcal=e: Enables multi-point calibration.
$Cgo: Starts compass for calibration. Rotate the towfish 360

degrees while rotating the towfish through the limits of
pitch and roll. This should be done over a time frame of
1 minute.

$Ch: Halt compass calibration.
$Cmpcal=d: Disables compass multi-point calibration mode.
$Cgo: Starts compass.
$TA1: Turn on altimeter transmitter.
$TM3: Turn on transducer transmitter.

Turn the towfish off and then on again and check that the compass is working.

CHAPTER 5: TECHNICAL DESCRIPTION

This chapter provides an overall technical description of the Series 5000 V2 Sonar
System towfish and TPU electronics. This information, which includes block
diagrams, printed circuit board descriptions, and chassis photos with callouts, is
useful when performing any troubleshooting tasks and when installing optional
equipment.

The Series 5000 V2 Sonar System departs from previous multibeam systems in
that the swath forming process is implemented digitally using digital signal
processing (DSP), rather than analog delay lines, phase shifters, or multipliers and
adders. The primary advantage of this technique is a reduction in the size and
weight of the towfish. This affords a accompanying reduction in the size of the
required survey vessel and ancillary equipment, such as a winch and crane. Other
advantages include more flexibility in the swath processing, allowing software
control of operating parameters. Previously this would have required hardware
changes.

5-1

5.1 Towfish

The towfish transmits and receives the sonar signals, processes them and outputs
the processed sonar and sensor data to the TPU over the tow cable. The primary
active components of the towfish are the sonar electronics and the two transducer
arrays. Heading, pitch, roll, and pressure sensors are also included, and an optional
responder and an altimeter can also be included.

5.1.1 Sonar Electronics

A block diagram depicting the functional relationships of all of the printed circuit
boards in the sonar electronics is shown in Figure 5-1. All the boards are located
on the towfish electronics chassis which is shown in Figure 5-2 on page 5-3.

The printed circuit boards, along with their corresponding part numbers, that make
up the towfish electronics are the following:

• Transmitter 14104530 14104530

• Receiver (2) 14104548 14104932-02

• Sensor Interface 14102038-01 14102038-01

• Multiplexer 14104941 14104941

w/o bathymetry w/bathymetry

• Power Supply 14104506 14104506

• Compass board 14104940 14104940

5-2 CHAPTER 5 Technical Description

Figure 5-1: Towfish Block Diagram—12 Sidescan Channels and 3 Bathymetery

Channels

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 optional 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 subsequent sampling.

Sensor Interface board. The Sensor Interface board conditions sensor data

from the compass board, depth pressure sensor, altimeter, and optional devices
for subsequent multiplexing and transmission to the TPU.

5-4 CHAPTER 5 Technical Description

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
by way of the tow cable. The Multiplexer board also receives the trigger signal
and command messages which instruct the T rans mitte r board to fire the arrays
and configure aspects of towfish operation. The Multiplexer board also acts as
a motherboard for the other boards providing the connections and distributing
power.

In addition, the Multiplexer board performs the following functions:

• Receives the 200 VDC and telemetry from the TPU 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.

• 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 to the TPU.

• Provides cable uplink and downlink interface.

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 towfish configuration.

Compass board. The compass board provides heading, pitch and roll.

5.1.2 Transducer Arrays

The two transducer arrays are each composed of 12 piezoelectric ceramic
sub-arrays that operate as both transmit and receive elements. Each set of
12 sub-arrays is arranged into a continuous line array spanning an overall aperture
of 1.2 meters. When the bathymetry option is present, 3 additional receive arrays
are included that feed the additional channels of the receiver boards.

Series 5000 V2 Sonar System Operations and Maintenance Manual P/N 11214512, Rev. 04

5.2 TPU

A block diagram depicting the functional relationships of all of the printed circuit
boards in the TPU electronics is shown in Figure 5-3. These boards are located in
the TPU electronics chassis as shown in Figure 5-4. The printed circuit boards,
along with their corresponding part numbers, are the following:

Assembled into a single rack mountable 3U enclosure, the TPU connects to the
towfish directly or by way of an optionally supplied winch. It also connects to the
SonarPro Workstation over an Ethernet connection and to customer supplied
equipment, such as a GPS and an acoustic positioning system.

TPU 5-5

• Demultiplexer board 14105785

• CPU board 14105873

• High Voltage Power Supply board 11700098

• 200V Power Filter board 14104980

• Topside Telemetry board 14105841

• 12V Power Filter board 14105397

• 12V Power Supply board 11700092

• LED board 14105464

Demultiplexer board. The Demultiplexer board demultiplexes the uplink

sonar and sensor data from the towfish and outputs FSK downlink commands
along with 200 VDC power to the towfish while providing all of the external
input and output signal and data connections for the TPU. It also provides the
required recovery of signal and clock, detects trigger inputs and 1-PPS signals,
generates the trigger outputs, inputs NMEA 0183 data, time stamps all of the
data, and outputs the data to the SonarPro Workstation over the Ethernet
connection. 200 VDC power is input to the Demultiplexer board from the
200V Power Filter board, and 12 VDC power is input from the 12V Power
Filter board. The Demultiplexer board also provides front panel indicator
outputs which drive the front panel LEDs on the LED board.

CPU board. The CPU board functions as the command and data interface

between the SonarPro Workstation and the tow fish. It executes a real-time
data server which outputs sonar and sensor data to and receives commands
from an external client, such as SonarPro.

High Voltage Power Supply board. The High Voltage Power Supply board

provides 200 VDC which is output to the towfish to power it.

200V Power Filter board. The 200V Power Filter board provides noise

filtering of the 200 VDC power for transmission to the towfish over the coaxial
tow cable. The filtered 200 VDC power is output to the Demultiplexer board
where it is combined with the FSK control signals and output to the towfish.

interface for the TPU. Specifically, the Topside Telemetry board performs the
following functions:

• Separates the uplink data signals, the downlink command signals and the
towfish power.

• Acquires sonar and sensor data and reformats the data as required for the
Demultiplexer board.

• Generates command and timing signals for the towfish.

• Matches the time references at the tow fish and the TPU.

12V Power Filter board. The 12V Power Filter board provides noise filtering

of the 12V power supply for the Demultiplexer board.

12V Power Supply board. The 12V Power Supply board inputs 100–125 or

200–250 VAC and outputs 12 VDC to the 12V Power Filter board.

LED board. The LED board contains all of the front panel LED indicators. It

mounts directly to the back of the front panel and connects to the
Demultiplexer board over a single cable.

APPENDIX A: SAMPLE TOWING

CHARACTERISTICS

Five towing characteristic graphs are included in this appendix as Figure A-1
through Figure A-5. Two of the graphs were generated without any additional
weight being added to the towfish, and the other two graphs were made with our
K-Wing II Depressor attached to the towfish. We believe you will find these
graphs helpful in planning your surveys and equipment requirements.

As with any projections of this type, certain conditions and assumptions were
made in order to generate a reasonable quantity of data with some degree of
accuracy. Read all the conditions below before you attempt to use the data.

Data. Data were computer generated using programs of known prediction

accuracy in both military and commercial towing systems. At best this type of
data provides "ballpark" values versus absolute values. These curves have been
checked with field data wherever possible. At best the values are within 15%
accurate with the greatest accuracy at towfish depths between 91 m (300 ft)
and 914 m (3000 ft) and at tow speeds of 3 to 7 knots. They are least accurate
at slow speeds and short cable lengths.

A-1

NOTE Depressors have minimal effect at speeds of 2 knots or less. Boat

motion plays a large role in shallow towing. For very deep towing, ocean
currents can completely change the cable characteristics.

Tow Cables. T ow cables having the characteristics below were used. Should

you have a different cable, it could make a significant difference.

• 10.2 mm (0.40 in.) nominal diameter double armored, galvanized steel;
weighing 353 kg per 1000 m (237 lb per 1000 ft) in air; 353 kN (11,000 lb)
breaking strength.

• 17.3 mm (0.68 in.) nominal diameter double armored, galvanized steel;
weighing 1030 kg per 1000 m (692 lb per 1000 ft) in air; 178 kN
(40,000 lb) breaking strength.

Cable drag increases with increasing cable diameter. The drag increases as the
velocity squared (V2). As cable weight per unit length increases, the cable tows
deeper.

A-2 APPENDIX A Sample Towing Characteristics

Towfish. The Klein Model 5250 stainless steel towfish was used in all cases.

It weighs 48 kg (105 lb) in water, is 16.8 cm (6.6 in.) in diameter and has a
length of 203 cm (79.9 in.). Smaller or larger towfish will only make a
difference when being towed on a cable of less than 60 m (200 ft) length at
speeds slower than 2 knots.

Depressor. The Klein K-Wing II, Model 402A-002 was used to create the

depressive forces in the calculations shown on three of the graphs. The K-W ing
mounts directly to the towfish end.

Interpreting the Graphs. Pick the graph closest to your operating

conditions. With a given speed and cable length, you can determine effective
tow depth. You can also determine the cable length required to reach a specific
depth at a given speed.

NOTE The graphs were calculated with the equipment and conditions

noted. The data can be used for different equipment and conditions by
extrapolating the data from the graphs.

More details on towing characteristics, such as tension, layback, etc., are available
at Klein Marine Systems, Inc. We would be glad to help you meet your
requirements. Your experiences in towing our side scan sonar under various
conditions would be helpful in upgrading our data, and we respectfully solicit your
comments.

APPENDIX B: NOTES ON HANDLING TOW

CABLES

A few methods on how to safely unreel tow cables are provided in this appendix.
In addition, how cable kinking can occur is identified along with what can result
from this condition.

B.1 Unreeling Tow Cable

The reel should be revolved and the rope taken off the way it was put on the reel as
shown in Figure B-1 for two effective methods. Place a shaft through the reel
center and jack it up so that the reel revolves freely. Pull the cable straight ahead,
keeping it taut, to prevent the cable from becoming loose on the reel. A board held
against a flange may be used as a brake to prevent the reel from revolving too fast.

B-1

Figure B-1: Correct Methods to Unreel Tow Cable

B-2 APPENDIX B Notes on Handling Tow Cables

B.2 Uncoiling Tow Cable

Remove ties and roll the coil along the ground so the rope lies straight. There will
be no twist or kink in the cable if these instructions are followed.

CAUTION If the reel and coil do not revolve freely, it will cause the cable

to twist as each turn is taken off. Kinking will result if the twist is not
removed and the cable straightened out before being placed under tension.

B.3 Cable Kinking

Cable kinking can be prevented if the cable is properly handled and installed. The
cause, the effect and the result of cable kinking are discussed below.

B.3.1 Cause of Cable Kinking

Kinking is caused when the cable takes a spiral shape as the result of an unnatural
twist. One of the most common causes of twisting is improper unreeling and
uncoiling. A cable loop and a cable kink are shown in Figure B-3. At the loop
stage no damage will occur if the loop is immediately straightened out before it
causes a kink.

Cable Loop Cable Kink

Figure B-3: Cable Loop and Kink

B.3.2 Effect of Cable Kinking

The effect of kinking is shown in Figure B-4. The cable is permanently damaged

Figure B-4: Damaged Cable

B.3.3 Result of Cable Kinking

The result of cable kinking is that strands and wires are displaced, creating uneven
tension which causes excessive wear at the point of the kink. The kink can be
straightened out so that the damage appears slight; however, since the relative
adjustment between strands has been disturbed, the cable cannot give maximum
service.

APPENDIX D: DIFFERENT TOW CABLE

LENGTHS AND THE
STARTUP.INI FILE

The Series 5000 V2 Sonar System operates at high data rates. For optimum
performance, settings have been provided to tune the system’s uplink for various
cable lengths up to -24 dB of insertion loss. The adjustment settings are made in
the Startup.ini file using the following two lines:

set PREEMPHISIS x
set LBOGAIN x

This file may be opened in any text editor such as Wordpad. After editing, save the
file.

D-1

The adjustment parameters are as follows:

set PREEMPHISIS x x = (0-7) SonarPro Command $ML x
set LBOGAIN x x = (0-3) SonarPro Command $MG x

We recommend the following:
For a 15-meter cable,

set PREEMPHISIS 1
set LBOGAIN 0

For a 150-meter cable,

set PREEMPHISIS 3
set LBOGAIN 1

For cables around 600 meters,

set PREEMPHISIS 7
set LBOGAIN 2

For cables that are longer, experimentation with the above settings should be done.
To do this, watch the yellow ERROR indicator on the TPU front panel. Vary the
uplink parameters until error-free operation is achieved. We recommend running
SonarPro and using the Towfish Diagnostics tab of the Sonar Interface dialog box.

D-2 APPENDIX D Different Tow Cable Lengths and the Startup.ini File

For example, when testing a 1000-meter cable, from SonarPro the following
command set yielded error-free operation: $MG2 and $ML7. Therefore the
Startup.ini file would be adjusted to contain the following:

set PREEMPHISIS 7
set LBOGAIN 2

D.1 Measuring Cable Insertion Loss

T o get an accurate assessme nt of your tow cable assembly, we suggest that you use
a Hewlett Packard 4194A Impedance/Gain-Phase Analyzer or similar.

A sample plot is shown in Figure D-1.

Figure D-1: Sample Plot of Tow Cable Characteristics

If you do not have access to a Hewlett Packard 4194A Impedance/Gain-Phase
Analyzer, you can get a close reading by using a function generator, a 50-ohm
terminator and an oscilloscope as shown in Figure D-2.

With the function generator and the oscilloscope connected to the cable, monitor
input on the oscilloscope and input a 1 volt peak (2 volt peak-to-peak) sine wave of
the specific frequency of interest. Measure the peak output at the other end of the
cable on the scope through the 50-ohm termination.

dB = 20 log (Vout /Vin)

For example, if at 15 MHz, you get a reading of 160 mv, then

dB = 20 log (0.16/1.0) = 15.9 dB loss.

NOTE The whole cable assembly must not exceed an attenuation of gr eater

than 24 dB of insertion loss at 15 MHz. We suggest a working loss of 24 dB
at 15 MHz.

D.2 Spare Tow Cable

Given the nature of high speed towing, cable problems can occur. For
troubleshooting purposes we suggest that you have on hand a lightweight Kevlar
reinforced 150-meter (minimum length) tow cable. This extra cable will allow you
to bypass your primary tow cable assembly and speed up fault isolation.
