Section 2 – Safety
2.1 Introduction
Before any activity is carried out on the equipment, it is recommended that the included Sonardyne
Safety Manual and all warnings and cautions in this manual are read and fully understood.
It is recommended the operator complies with the Health and Safety Regulations applicable to the
vessel and the region before operating this equipment.
Operators and service personnel must be familiar with the normal operating and safety procedures
for subsea equipment.
Documentation must be consulted whenever a or warning symbol is found on the
equipment, in order to determine the nature of the potential hazard and any actions which must be
taken.
If any additional equipment is used, any warnings and cautions in the equipment user manual must
be read and fully understood and the equipment must only be used as specified by the
manufacturer.
The safety of any system incorporating this equipment is the responsibility of the assembler of the
system.
2.2 Safety Procedures
Before carrying out any procedure on the equipment, make sure that all of the following warnings
and cautions are read and fully understood.
2.2.1 Warnings
Personal protection. Appropriate protective equipment such as protective footwear, hard hat
and gloves must be worn when handling or carrying out any procedures involving Sonardyne and
other equipment.
Heavy Equipment. Many Sonardyne products and equipment types, such as transponders,
transceivers, cable drums etc. require Manual Handling Equipment (MHE) for lifting due to their heavy
weight. If MHE is not available, it is the responsibility of the operator to perform a manual handling
risk assessment prior to carrying out manual lifting/handling. Refer to the individual equipment
documentation for weight specifications.
Hazardous Substance. Molykote 44 is a mild irritant. When lubricating connector faces,
Personal Protective Equipment such as gloves and goggles must be worn.
Do not carry out maintenance on the transceiver if the housing is hot. Disconnect all power and
wait for the housing to cool.

Section 2 – Safety 3
2.2.2 Cautions
Loss of connector Integrity. Do not over apply grease to the female connector. Grease build up
will affect connector integrity.
Damage to transceiver. The weight of the mounting pole must not be supported by the
transceiver front face.
Damage to protective coating. Do not use any abrasive brushes or sharp tools to clean the
transponder and remove any marine growth, this will damage the protective coating and increase the
risk of corrosion.
The weight of the deployment pole must not be supported by the transceiver front face.

3.1 Introduction
The Sonardyne Wideband ®2 6G®Series of Ultra-Short-Baseline (USBL) High Performance
Transceivers (HPT) are used as part of the USBL, Long-Ultra-Short-Baseline (LUSBL) Marine Riser
Angle Monitoring System (MRAMS) and data retrieval systems.
The Wideband 2 technology uses a correlation reception technique with phase-encoded signals
over a wide range of carrier frequencies. Signal coding allows for hundreds of channels enabling
multiple users to work in the same area without interference.
This manual covers the USBL transceiver variants shown in Table 3-1.

3.2 Description
3.2.1 HPT 2000 – Type 8221-000-01
The type 8221-000-01 HPT 2000 6G USBL transceiver is a small, light, Ethernet interfaced HF
band USBL with a short range array optimised for shallow water and high elevation tracking in low
noise environments up to 2000 m.
The HPT 2000 contains an internal attitude sensor and magnetic compass, mounted inside the
head. It is important to note that this is a magnetic compass and therefore requires a Magnetic
Offset deviation value to be entered between true north and magnetic north.
It is recommended to calibrate the internal compass when the HPT 2000 is first deployed; see
Section 4.2 “Type 82212/8212 Internal Compass Calibration”.

3.2.2 HPT 3000 – Type 8212-000-01
The type 8212-000-01 HPT 3000 6G USBL transceiver has the same specification as the HPT
2000 described above but operates in the MF band.
It is recommended to calibrate the internal compass when the HPT 3000 is first deployed; see
Section 4.2 “Type 82212/8212 Internal Compass Calibration”.

3.3 USBL Transceiver Operation
The USBL transceiver is a complete digital signal processor controlled acoustic interrogator /
receiver operating on a command from the Data Fusion Engine (DFE). In other applications the
USBL transceiver can passively monitor acoustic activity.
The main functions of the USBL transceivers are as follows:
•Interpretation of commands from the DFE.
•Transmission of acoustic commands or transponder interrogation signals on any one of
Sonardyne Wideband®2 signals.
•Reception of transponder reply signals can be on any one of Sonardyne Wideband®2
signals.
•Decoding acoustic telemetry.
•Measurement of time and bearing (Type 8212 & 8142 only) in the received transponder
reply.
•Transmission of range, (bearing, Type 8212 & 8142 only) and telemetry data to the DFE.

Section 3 – Technical Description 10
The electronic components are as follows:
•Voltage regulations circuits.
•Analogue conditioning and digitisation.
•Digital signal processing module.
•Transmit circuit controlled by the processor.
•Communications module providing RS485 and Ethernet communications.
The transducer face contains an array of ceramic receiver and transmit elements. The elements are
recessed into a high grade plastic and encased in polyurethane to form a strong smooth acoustic
interface to the water.
The electronics chassis is attached to a metal base plate of the transducer face assembly. A
cylindrical housing slides over the electronics chassis to mate with the face of the metal base plate
and is secured with six bolts. The housing is constructed in Aluminium Bronze to resist corrosion.
The processor within the USBL transceiver runs a program stored in firmware which controls all the
functions of the unit.
An underwater connector is provided in the top of the housing for connection with the interface
cable.
Nominally 48 V power is supplied to the unit using a single pair of conductors. Primary
communications is achieved by half duplex RS485 link or Ethernet. Diagnostics and additional data
channels are provided using a secondary half duplex RS485 link. A signal ground is provided to
make sure there are reliable communications for both RS485 channels.
