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.
CAUTION
The depth rating on the transducers is 200 meters (656 feet).
Operations at depths greater than 200 meters may damage the
transducers.
CAUTION
When the towfish is close to the sea floor, the 900-kHz bottom
tracking (altitude) performance is not exact. Klein Marine Systems,
Inc. advises extreme caution when operating the towfish at altitudes
of less than 4 meters (13 feet).

CHAPTER 1: OVERVIEW
The Series 3900 Sonar System displays sonar data on a high resolution monitor
and will store data on both the hard disk drive and a CD for high capacity storage.
Many optional accessories may be added to the basic system for special situations
or applications. This sonar equipment provides the capability for precision swath
imaging of the sea floor.
1.1 Equipment
The Series 3900 Sonar System equipment consists of a single beam sonar
instrumented towfish, a Transceiver and Processing Unit (TPU), and a Windows
Computer Display and Control Unit (computer), along with a tow cable and
various interconnect cables.
1.1.1 Single Beam Sonar Instrumented Towfish
The towfish electronics perform all the sonar data processing prior to digital
transmission to the sonar TPU. This minimizes the system’s susceptibility to
externally induced electronic noise. Processing includes transmit/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. Use of a low noise preamplifier design ensures
maximum range performance. The ability to operate with a fiber-optic cable is
available as an option for very long cable (deep tow) operations or installations
requiring electrical isolation in severe noise environments.
An electro-mechanical termination is provided on the towfish end of the tow cable
for connection to the towfish. A tow shackle provides a strong, reliable,
mechanical termination to the towfish tow bracket. An underwater connector on a
pigtail connects the tow cable electrically to an underwater jumper cable on the
towfish.
1.1.2 Transceiver and Processing Unit (TPU)
The TPU contains the electronics for sonar data demultiplexing and data
processing.

1-2 CHAPTER 1 Overview
Series 3900 Sonar System Operations and Maintenance Manual 11214510, Rev. 02
1.1.3 Computer Display and Control Unit
The Computer Display and Control Unit (computer) supports the PC based
Windows operating system as the display and control interface. This provides for
an easy to use familiar graphical user interface and simple expansion capabilities
to a wide assortment of equipment. The software is set up in a client-server format,
allowing for flexible and expandable system configurations with multiple
computers connected over a TCP/IP fast Ethernet network, all sharing the sonar
data.
1.1.4 Tow Cable
Coaxial or optional fiber-optic tow cable is used to transmit data bidirectionally
from the towfish to the TPU.
1.2 Features
The Series 3900 Sonar System has the following capabilities:
• Advanced electronics and transducers that produce superior high
resolution imagery
• 12-bit digital multiplexer for transmission of sonar and control
data over a single coaxial cable
