1 INTRODUCTION
The MB1 multibeam echo sounder is a portable, easy to use bathymetric system that is designed to
collect swath bathymetry using acoustic means. Developed by the Teledyne Marine Group of companies,
it has been designed with the surveyor in mind to be simple to use yet provide full functionality.
To make learning about the features of MB1 easy to follow, this document is structured as a step-by-step
manual. The first manual (this manual) covers the MB1 as a product, it provides instructions on how to
install the hardware, how cables are wired to their connectors and some simple troubleshooting tips. The
second manual details the control software and how the system can be used operationally. Both manuals
should be used together to learn how to use the system.
It is recommended that before the system is operated for the first time, the user should familiarize
themselves with the contents of this manual in order to ensure optimal use of the system.
1.1 Warnings and Cautions
Throughout this manual there are several points that may either result in damage and/or loss of the
system (Warnings) and other points that may result in improper use of the system (Cautions). These are
annotated using the following format.
Warning: (Example) Applying DC electrical power greater than 30 Volts to the RTA
may result in damage to the unit.
Caution: (Example) Ensure that the cable of the unit is facing aft (toward the rear
of the vessel) during normal operation.

2 PRODUCT DESCRIPTION
2.1 System Overview
The MB1 consists of a multibeam sonar unit with an interface unit, called the Real Time Appliance (RTA).
In order to be effectively used for hydrographic surveying, the user will require additional components for
positioning, motion sensing, collection of data, determining sound velocity in the water as well as a
computer to run the operating software. These components may have been supplied with the equipment
or purchased separately.

2.2 Sounder
The sounder is the device that performs three main functions. First, it houses the transmit and receive
acoustic arrays that send and receive sound. Secondly, it houses all of the analog to digital conversion
hardware, to pass digital signal information via the power/data cable to the RTA. Thirdly, the unit may
house an internal motion sensor and/or sound velocity probe, dependent on the configuration purchased.
2.3 Real Time Appliance (RTA)
The RTA performs 3 functions:
(a) Supplies electrical power to the Sonar
(b) Acts as a junction box to interface all the required sensors in one device
(c) Aligns and time tags all data streams and outputs to the controller computer
In addition the RTA can be configured with an internal GPS heading sensor, that when used with two
antennas can determine the vessel position and heading for use with the sonar.
2.4 Power/Data Cable

MB1
User Manual
Page 7 of 37
7/6/12
This is a specially constructed cable for MB1, terminated at the wet end (sonar end) with an Impulse Titan
series connector, and at the RTA end with an Amphenol connector. Replacement part number 2313-
0100-0000.
2.5 Mounting Plate
This prefabricated stainless steel plate can be used as a generic mounting arrangement for most over the
side mounts.
2.6 Digibar V (optional)
The Digibar V is an instrument that determines sound velocity at a fixed point. This sound velocity is
used by the MB1 software in calculating the receive beams of the multibeam, and is required for correct
use of the system. A different real time sound velocity probe may be used and interfaced to the RTA
using the SVP port, providing the AML sentence can be output.

2.7 Power Supply
This is a recommended 100-240V A/C power supply with an output of 24V at 100W. This may be used to
power the sounder through the RTA. Alternatively a DC power cable can be supplied (Part number:
CABLEPOWDC) by Odom when required.
2.8 Possible Configurations of the MB1
The MB1 can be used as a standalone sonar as part of a pre existing suite of other sensors (Motion,
Heading, Position etc.) or has configurable options.
The options that may be added to the system are an internal GPS & Heading board (Hemisphere H320
model), TSS DMS525 motion sensor and the Digibar V real time sound velocity probe. Any of these
inputs can be configured to either be external (input to either the RTA or sonar head) or internal as fitted
to the equipment. The table below shows the possible configurations.

3 COMPONENTS
3.1 Sounder
The sounder consists of a Titanium lower portion, housing the acoustic transmit and receive arrays. The
upper portion houses the internal electronics and is manufactured from Acetal, a tough and corrosion
resistant plastic. The two connectors shown above are used for a connection to a real time sound
velocity probe, the Odom Digibar V, and the other is a power/data interface for the unit. On the top of the
unit are 4 bronze mounting rods that are threaded to accept 8 mounting bolts through the top of the unit.

7/6/12
Turning the unit over, the transmit array (the larger black square) and the receive array (the smaller black
square) can be clearly seen. A carrying handle is located at one end of the base of the unit, and may
also be used as a tie off point to prevent loss in the event that the sonar mount was to break.
3.1.1 Optional Internal Motion Sensor
If the unit has been supplied with an internal motion sensor, this can be used instead of an external
sensor to correct for vessel motion. The advantage of the internal sensor is reduced set up time (the
cabling is already in place and offsets do not need to be measured between the sonar and the motion
sensor) and also in vessels with temporary mounts the mount flex will be measured by the motion sensor.
3.1.2 Maintenance
The sounder should be kept clean and free from marine growth where possible. Although the system has
been manufactured using corrosion resistant materials, it is prudent to inspect and clean the sounder at
regular intervals, especially if it is to be immersed in water for long periods of time.
Special care should be taken to ensure the transmit and receive arrays are kept free from growth and are
not scratched in any way. A non-abrasive cleaning product should be used to clean the unit, then it is to
be stored in a dry environment.
Caution: Care must be taken not to scratch the transmit and receive array. Ensure
it is placed on a clean surface free from items that may damage these sensitive
components
Regular application of silicone grease or equivalent is recommended on the Digibar V connection plug to
prevent corrosion and wear.
The transmit and receive arrays are not to be coated with any form of paint, including antifouling. This will
interfere with the correct operation of the acoustics.
3.1.3 Handling
The sounder may or may not have an enclosed motion sensing unit, depending on the configuration
purchased. In either case, it is important to ensure that the unit is not dropped or suffers any shock
damage. This may either damage the internal components or offset the alignment between the arrays.
Warning: Care is to be taken to avoid shock damage to the unit, especially in
transit. Always ship the unit using the supplied shipping container.
3.2 Real Time Appliance (RTA)
The RTA is the center of the MB1 system. It serves as the connection box for all the sensors as well as
providing better than 1 ms timing on all sensors including the sonar.
The front panel of the RTA has status LEDs that indicate whether data has been received from the sensor
and the rear panel has all the connections to the sensor.

MB1
User Manual
Page 11 of 37
7/6/12
When setting up the MB1, the RTA should be placed on a non-insulating surface wherever possible to
encourage heat to dissipate from the base plate. This is especially important in hot environments or
where the unit is exposed to sunlight. Failure to sufficiently dissipate the heat may result in a safety
hazard to personnel.
3.2.1 Front Panel
The front panel of the RTA consists of a series of status indicating LEDs, which tell the user when data is
being received to the RTA from each sensor. The RTA and sonar are also powered by depressing the
circular power button to the right of the front panel.
Before the RTA will indicate the correct sequencing of lights, each sensor must be attached and
configured in section 3.2.2 of this manual.
Once the power button is depressed, the lights will perform the following self check sequence:
(a) All lights in the IO box will flash once.
(b) The Link lights for both Sonar 1 and 2 will flash once.
(c) After 10 seconds, the Link lights for both Sonar 1 and 2 will flash once again.
(d) After 35 seconds, the link light for the sonar will begin to flash, and the system is ready for use.
Caution: The system is ready for use only when the Link light is flashing
During normal operation the status lights will flash in the following manner:

3.2.2 Rear Panel
The rear panel of the RTA is where all of the external sensors are connected. Each connection is
detailed below:
3.2.2.1 Power
Amphenol connector carrying DC power, 12-30V. This will interface with the power supply part number
3015-0001-0000 or another power supply previously supplied by Odom with the same connector.
3.2.2.2 1PPS In
1PPS can be introduced to the RTA in one of 2 ways. Firstly is a BNC connector marked ‘1PPS In’,
which connects via a length of Coaxial from the GPS providing 1PPS. The second method is through the
GPS I/O pin 9 (see paragraph 3.2.2.3 below).
The accepted 1PPS is the standard GPS output (1ms square waveform every 1 second). A limited
number of devices output a 1 second square waveform (also known as flip flop) – this will not be
accepted by the RTA.
By default, the system is configured to accept the PPS pulse through either the BNC connector or pin 9 of
the GPS I/O RS232 connector. Either one should be used for the PPS, not both. Some GPS devices
such as the C-Nav 2050 & 3050, however, output other signals on pin 9 of their RS232 that may interfere

MB1
User Manual

7/6/12
with the timing of the RTA when the BNC is used for the PPS signal. This will be seen as a timing error
within the Image control software, along with the PPS LED blinking at rates other than once per second.
If this occurs, pin 9 of the GPS I/O RS232 can be disabled in one of two ways:
(a) A null modem with pin 9 disabled can be used to interface between the GPS and the GPS I/O on
the RTA.
(b) The PPS can be set within the RTA itself, inside of the unit on the back panel. To change the
PPS input method from the default (BNC and Pin9) to BNC or Pin8 or Pin9 perform the following
procedure:
(i) Disconnect the power cable. With the rear of the RTA facing you, remove all of the connector
plugs.
(ii) Using a 3mm allen key, remove the 7 bolts that hold the rear panel to the casing of the RTA.
Carefully pull the rear panel away from the casing, ensuring that the cables are not put under tension.

MB1
User Manual

7/6/12
(iii) Mounted to the rear panel is the interface board to the serial connectors. This has 4 small jumper
connections, two of which will determine whether pin 9 and pin 8 can be used to accept the PPS signal.
There are also two disconnected jumpers at the top of the board - do not change these.
(iv) The small black connector bridges the two pins when connected, and sits on only one of the pins
when disconnected. Below we can see the default, pin 8 (JP4) is disconnected on the right and pin 9
(JP3) is connected on the left.
(v) To disable pin 9, remove the jumper connector from both pins and reattach to a single pin.
(vi) (If required) to enable pin 8, remove the jumper connector from the single pin and attach to both
pins.
(vii) Re-align the rear panel with the RTA housing, ensuring that the O-ring seal is correctly seated in
the groove on the rear panel. Insert the 7 bolts into the rear panel and tighten with the allen key.
