1. SYSTEM FAMILIARIZATION
1.1 OVERVIEW
The SIMRAD SL 30/35 Hull Sonar Series is a short range, mechanical scanning
sonar designed for small and medium sized purse seiners and trawl fishing vessels.
The system provides real time images from the sonar dome to the bridge, thus
maximizing the best possible presentation on a high-resolution colour monitor,
providing the operator with 6 different display modes and 4 customized user modes,
giving a flexible choice for a large range of user applications.
The SL 303/35 Sonar allows the operator to monitor the complete operation, by
displaying individual fish school target locations in the Horizontal Plane. In addition
to the Horizontal plane, the SL 30/35 Sonar provides a Vertical Fan mode, specially
made for trawling, where a complete overview of the Horizontal and Vertical Planes
are presented.
The sonar beam can be horizontally trained 360°and 180°in the Vertical Plane.
The automatic search features and full -90° tilt capability ensure maximum control
during the tow and/or pursing. The active motion compensation for pitch and roll and
the audio speaker are optional.
The SL 30/35 Sonar is a modular system. It is operated with ease through a direct
access Control Panel with an integrated mouse.
1.1.1 Equipment Configuration
A complete SL 30/35 Hull Sonar consists of:
•Simrad LCD or VGA Display Monitor. (Optional)
•SL 30/35 Processor Unit.

1.1.3 Display
The display monitor for the SL 30/35 Sonar can be either a VGA “CRT” or LCD
Simrad ruggedized monitor, but any commercially available monitor may be used. In
order to have the full benefit of high resolution, you should use a Simrad LCD
Monitor.
1.1.4 Processor Unit
The SL 30/35 Sonar Processing Unit is a ruggedized computer, which can interface
with other auxiliary equipment (Control Panel, Interface Unit, GPS, Echo Sounder
and Trawl Systems, etc.). The processor unit runs on the Microsoft Windows XP
Operating System. The SL 30/35 Sonar System software provides a mechanism for
the sonar operation. It is operated through the Main Control Panel to enable the
sonar selection, tilt, range, gain and cursors; moving the mouse pointer over the
toolbar will allow the operator to perform certain operations with a simple mouse
click. A flush mounted Control Panel is provided to simplify the operation of the
system.
The rear panel of the processing unit contains the connectors for AC and DC power,
Monitor port, two RS232 Serial Ports, Keyboard, Mouse, Printer, Network LAN and
USB port. The Network LAN port can be used to connect a remote workstation, or to
download data from the processing unit.
Note: A security key (or “dongle”) must be attached to the parallel port to enable
full operation of the system.
1.1.5 Control Panel and Interface Unit
The SL 30/35 Control Panel contains all necessary control functions for operating
the sonar. As some of the functions are used more frequently than others, the
control buttons are arranged in function groups, as Sector Train, Tilt, Scan Speed,
Range, Display Mode, User Setting and Utilities. The Power ON and OFF buttons,
the Lower and Raise buttons are also provided for on the SL 35 Hoist Control.
Note:All sonar operations may also be controlled from the integrated roller ball, or
from an optional remote standard mouse.
The SL 30/35 Interface Unit is incorporated into the Control Panel assembly,
providing the interface telemetry communication between the Processing Unit and
the Transceiver Unit in the sonar room.
Note that only one signal cable is used for communication between the Interface
Unit and the Transceiver Unit.

1.1.6 Sonar Room Unit
The Transceiver Unit and Lower/Raise Unit are located in the sonar room, mounted
to the tank flange.
The Hull Unit sonar dome is lowered 250 millimeters or 400 millimeters below the
ship’s hull. In case of a power failure the dome assembly will automatically retract
back up into the sonar tank.
Note: The sonar dome can be manually raised by means of a hand pump.
The optional motion sensor for the electronic stabilization of the sonar beams is also
located in the sonar room. A 10 meters interconnection cable is supplied.
WARNING!!
If the sonar dome hits a large object or the bottom, the dome shaft
may be bent, or in the worst case it can be broken off. A broken
sonar dome may cause water leakage at the top of the shaft. To
prevent large leakages in such a case, DO NOT raise the sonar
dome shaft to the upper position. It is therefore of great importance to
have a good pump and warning system in the sonar room.
DISCLAIMER
This equipment is not certified or approved for navigation and/or safe-
navigation practices and is not to be used for navigation purposes
under any circumstances.

2. SYSTEM DESCRIPTION
2.1 INTRODUCTION
This section explains the theory of operation of the SL 30/35 Mechanical Scanning
Sonar System.
2.1.1 Basic Principles
•Sound waves travel very efficiently through water.
•A sound pulse can be projected through water in a controlled direction with the
sonar transducer.
•An object in the path of the projected sound pulse will reflect some sound pulse
back toward the sonar transducer.
•The speed of the sound pulse projected through the water can be predicted for
given conditions.
2.1.2 Determining Target Position
The SL 30/35 scanning sonar processor measures the time from the start of the
sound pulse projected through water, to the reception of the sound pulse reflected
back to the sonar transducer. The measured time is then converted to distance by
using the speed of sound through water.
Since the sound pulse is projected in a known direction, the bearing of the reflected
object is also known. This makes it possible to locate the object with respect to the
sonar transducer; the information will be used to plot the position of the reflected
target on a video graphic display monitor.
2.1.3 Forming an Image
The sound pulse projected will be attenuated as it travels through the water from the
transducer to the target and back. Much of this attenuation is a predictable function
of the total time or the distance the sound pulse traveled through water. Increasing
the receiving gain with time can compensate for this decrease in the signal level.
This is done automatically in the sonar with a Time Varying Gain circuit.

Port Coquitlam, BC - Canada
After the TVG correction, the absolute levels of the received signals will be
determined by the acoustic response of the reflecting target.
The sonar processor system repeatedly measures the TVG corrected target levels
by digitizing a sequence of samples after each sound pulse transmission. Each
sample is then plotted on the video display at the appropriate position according to
its range and bearing. The level of the target strength sample determines the color
used to plot each sample.
The process can be repeated with the transducer pointed in different directions,
forming an image of a large area of the bottom and displaying it on the video screen.
2.1.4 Wheelhouse Units Description
The following paragraphs will describe the key features of the Wheelhouse Units of
the SL 30/35 Hull Sonar.
2.1.4.1 Display Monitor
The display monitor required for the SL 30/35 can be either a VGA “CRT” type or
any commercial LCD monitor. In order to have the full benefit of high resolution, we
recommend that you select the Simrad ruggedized LCD colour monitor. The Simrad
colour monitors are available in two sizes, 18” and 20”. The monitor can be desk,
ceiling, or flush mounted into the bridge console.
The Simrad LCD monitor will run on 110/240VAC, 50/60Hz or on 24VDC, +/- 10%.
All mounting hardware is included.
2.1.4.2 Processor Unit
The processor unit is a ruggedized HP “Hewlett Packard” Compaq Processing Unit
designed for use in a marine environment. The processor unit runs on the Microsoft
Windows XP Professional Operating System.
In the event that you have a problem with the HP computer we recommend that you
contact your Simrad dealer or Agent to assist you in solving the problem.
Hewlett Packard Customer Center can help you solve hardware issues related to HP
products and, if necessary, initiate the appropriate service procedures. In the U.S.A.,
telephone support is available 24 hours a day, seven days a week. Elsewhere, in the
world, it is available during normal office hours.
