1-2 CHAPTER 1 Overview
HydroChart 3500 Sonar System Operations and Maintenance Manual P/N 11210087, Rev. 03
1.3 455-kHz Operation
The HydroChart 3500 Sonar System operates at 455 kHz which provides excellent
detection of medium to large targets at ranges exceeding 175 meters per side for a
total swath of 350 meters. Bathymetry coverage is up to 12 times the altitude, and
all acquired data supports the IHO S-44 Special Order Standard for Hydrographic
Surveys. And when combined with the Klein Marine Systems uncertainty model,
the data allows for automated/intelligent data processing.
1.4 System Components
The HydroChart 3500 Sonar System includes three main components: a Sonar
Head Unit, a Topside Interconnect Unit (TIU) and a deck cable. These components
are shown in Figure 1-1. A PC with the Microsoft Windows XP or Windows 7
operating system and Klein Marine Systems SonarPro installed along with an
optionally connected navigation device are the only additional components
required. The Sonar Head Unit, the PC and the navigation device connect directly
to the TIU.
1.4.1 Sonar Head Unit
The Sonar Head Unit includes all of the electronics required to transmit, to receive
and to process the sonar signals, and to output the sonar and optional sensor data
over an Ethernet 100Base-T connection to the TIU. The electronics, including an
optional motion reference unit (MRU), is contained inside a waterproof housing
that includes bulkhead connectors for connecting to the port and starboard
transducer arrays and to optional compass and sound velocity sensors. A connector
is also provided for a jumper cable which is used to connect to the deck cable. The
sonar electronics housing, transducer arrays and optional sensors are all mounted
to a light weight frame and surrounded by a two-part plastic fairing, one forward
and one aft. The frame includes a mounting flange which easily attaches to a
customer provided over-the-side mounting pole or ram. Both the housing and the
frame are constructed of hard coat anodized high grade aluminum.
1.4.2 Topside Interconnect Unit (TIU)
The TIU is a small, IP-65 rated enclosure that provides DC power to the Sonar
Head Unit, interfaces with both a PC and the Sonar Head Unit over an Ethernet
100Base-T connection, provides a connection to a navigation device over an
RS-232 serial interface, and accepts a one pulse per second (1PPS) input from the
navigation device or a separate time reference unit. It operates on 120/240 VAC,
50/60 Hz or 24 VDC power. A single push button switch turns the TIU on or off,
and an indicator provides both a power on indication and flashes when the Sonar
Head Unit is operating and its transducers are transmitting.

The deck cable is a 10-meter (20 or 50-meter optional) polyurethane jacketed
Kevlar reinforced Cat 6 with four twisted shielded pair 23-AWG conductors for
communications and four 20-AWG conductors for power. It includes a dry
connector on one end for connecting to the TIU and an underwater connector with
a locking collar at the other end for connecting to the jumper cable on the Sonar
Head Unit.
