B1500C Overview – Safety
The following are general safety precautions that are not related to any
specific procedures and therefore do not appear elsewhere in this
publication. These are recommended precautions that personnel must
understand and apply during many phases of operation and maintenance.
KEEP AWAY FROM LIVE CIRCUITS- Operating personnel must at all
times observe all safety regulations. Do not replace components or make
adjustments inside the equipment with the high voltage supply turned on. Under
certain conditions, dangerous potentials may exist when the power control is in the
off position, due to charges retained by capacitors. To avoid casualties, always
remove power and discharge and ground a circuit before touching it.
DO NOT SERVICE OR ADJUST- Under no circumstances should any
person reach into to enter the enclosure for the purposes of servicing or adjusting
the equipment except in the presence of someone who is capable of rendering aid.
RESUSCITATION- Personnel working with or near high voltages should be
familiar with modern methods of resuscitation.
WARNING- 200Volts DC present. Risk of electrical shock and serious injury is
WARNING- High Voltage may be present until the High Voltage Capacitors
CAUTION- The B1500C has many ESD (Electrostatic Sensitive Devices).
Normal precautions involve the use of anti-static protection material and ground
straps for test personnel.
B1500C Overview – Safety
Shipping and Handling - The Bathy-1500C units
are delivered in reinforced cardboard with packing foam inside.
The boxes and foam should be saved for future use. If saving
the box and foam is not practical, equivalent packaging
procedure should be used.
Emergency Operation and Shutdown -
Under any emergency, adverse, or abnormal ship conditions, the
Bathy-1500C system electronics should be powered down. The
system is powered down by placing the toggle switch on the front

Zoom modes, and 1 without any zoom.
Bottom Zoom
Bottom Lock Zoom
Marker Zoom
Bottom Zoom Mode
When selected, this mode will split the viewing area in half. The left side will be
used to show zoom information, and the right side for normal bottom data.
Bottom Zoom mode centers the zoom display around the current depth allowing
you to follow it up and down the water column at a high resolution. In addition,
the user can use the Zoom Range Control to zoom in or out.
The Zoom Range value represents the zoom range in whichever units are
currently selected. When the zoom window moves up or down to track the
bottom, it does so in Zoom Range / 2 increments.
Bottom Lock Zoom Mode
This mode functions the same way as Bottom Zoom, however it
does not show the bottom moving through the water column.
Instead, it will lock the bottom to the upper portion of the zoom
view so that the user may continuously monitor sub-bottom
Marker Zoom Mode
Like in the other modes, Marker Zoom provides a high-resolution zoomed
view of the water column, however in this mode, the user can specify
where in the water column the zoom range will begin.
This is
accomplished by dragging the marker zoom bar up or down the normal
view scale bar to the point you want the zoom range to begin. The start of
the zoom range can be observed at the top of the zoom window while you
drag the marker zoom bar, but the marker zoom isn’t set until the mouse
button is released.
Help Menu
This menu includes a software Help guide along with an About
Bathy-1500C option. Clicking it will display a window with
information such as the Bathy-1500C’s software version and
SyQwest, Inc.’s company information. In addition, the software
will request and display Hardware/Firmware version information
from the Bathy-1500C’s DSP to ensure it is connected and
communicating properly.
Theory of Operation
The Bathy-1500C system is configured as a flexible
acoustic measurement sensor device capable of
providing an excellent solution for both shallow
water and deep water hydrographic applications.
Both applications make use of the appropriate signal
processing features to perform accurate and reliable
bottom digitizing. The Bathy-1500C makes use of
sophisticated algorithms for first/peak bottom echo
detection, automatic mode controls for: receiver
gain, bottom tracking, pulse length and power level
controls greatly reduce the probability of inaccurate
bottom detection/tracking.

Installing the Bathy-1500C
Selecting a Location for the Electronics
The Bathy-1500C Sensor Unit is designed for portable, marine applications but maybe
used in permanent installations as well. The user must determine if the Bathy1500C Sensor Unit is to be mounted on the vessel or just placed in a convenient
place on-board the vessel. Either way the appropriate location for the unit needs
to be determined. The following considerations should be investigated before
deciding upon a location:
1. Panel PC Display Unit - Select the optimum place where data may be viewed.
2. Cable Lengths. - Data and Power Cable lengths are 10 feet. Thus, the Sensor Unit
must be installed within 10 feet of both the user supplied Personal Computer and
a 10-30VDC Power Source. The unit must also provide adequate access for
cabling termination without binding, and allow suitable space for servicing the
equipment. (If necessary, the data cable may be extended beyond 10 feet.)
3. Water Resistance. - The unit is NOT watertight or splash proof.
4. Environmental. - The operating temperature is –25C to +60C.
Mounting the Sensor Unit
The Sensor unit may be mounted either
horizontally or vertically. The slotted
mounting holes make installation in
hard to reach areas easier, but be sure
to tighten all mounting hardware
securely. Insure that adequate room
is left for installing and removing the
cable connections. Also, verify that
the power switch is easily accessible
and that the Power status indicator is
visible. Other considerations include
having adequate space for facilitating
the cable installation, and having
sufficient clean air exchange to satisfy
ventilation requirements.
Mounting the Bathy-1500C
Display Unit
The unit may be mounted either
panel mount, bulkhead mount, or
rack mounted. The display has
simple to use, attached mounting
clips on the rear of the display that
can be loosened and spun to
attach the display to panel mount
or bulkhead mount, an optional
rackmount panel kit is required to
rackmount the unit. Be sure to
tighten all mounting hardware
securely. Other considerations
include having adequate space for
facilitating the cable installation,
and having sufficient clean air
exchange to satisfy ventilation
Installing the Bathy-1500C
General Transducer
The Bathy-1500C is offered equipped with a single frequency or dual frequency
transducer that is designed for portable, over-the-side mount applications. It may
also be used in permanent installations. Before installing the transducer, the
installer should read and understand the appropriate section below to insure that
all of the installation issues are considered.
Selecting a Location for the Transducer
The location of the transducer is very important for maintaining reliable bottom
tracking and optimum performance of the equipment. Avoid installing transducers in
locations where the transducer will be subjected to turbulent water, air bubbles, or
vibration. The best clear water location on most vessels meeting these criteria is
approximately 1/3 the length of the vessel, aft from the bow.

The best clear water location on most vessels meeting
these criteria is approximately 1/3 the length of the
vessel, aft from the bow.
Handling Transducers
The transducer is the heart of the Bathy-1500C system and, in spite of its
appearance and size, is a delicate instrument. Although it is designed to be in
contact with and survive tough marine environments, it should not be dropped
or mishandled during the installation. Caution is advised when handling the
transducer to prevent any damage to the transducer face or radiating surface.
The transducer and mounting assembly should be as clean and smooth as
possible so the path of the sounding energy is uninterrupted. The transducer
face must not be painted with lead based bottom paint. In portable
applications the transducer and mounting assembly should be cleaned with
fresh water after use.
WARNING: Do not expose the transducer to any solvents when cleaning
any excess sealants. Strong solvents may damage the face of the
Also, when handling the transducer, avoid lifting or pulling on the transducer
cable. Although the cable appears thick and substantial, the internal cable
wiring could be damaged by stress from the sheer weight of the transducer and
cause a malfunction at the most inopportune time.
Portable Transducer Installation
Portable installations of the Bathy-1500C transducer for most survey vessels will be of the overthe-side pipe mount type. This type of installation is achieved with the following list of materials:

this may sever internal connections.
Over The Side Transducer Mounting
(Example mount shown as reference only)
Portable Transducer Maintenance
Aquatic growth can accumulate rapidly on the transducer's surface
reducing its performance in weeks. Clean the surface, keeping it free of
marine growth and petroleum residue, with a soft cloth and mild
household detergent. Inspect the cable periodically for kinks, abrasions
and cuts. Repair any damage using an approved waterproofing cable
repair system. Inspect connections for indications of corrosion.
Certain cleaners, gasoline, paint, sealants and other products
may contain strong solvents, such as acetone, which can attack many
plastics dramatically reducing their strength. Clean surface of
transducer with a mild detergent only.
Permanent Transducer Installation
For some applications it may be necessary and/or convenient to mount the BathyBathy-1500C Transducer
permanently in the hull of the vessel. Due to the construction of the BathyBathy-1500C Transducer it may be
directly affixed to the hull of the vessel. A Seachest Installation
Installation can be used, but is not required.
Guidelines for performing a Seachest installation are described in the following sections.
Seachest Transducer Installation
Interior Seachest installations are best suited for solid fiberglass
fiberglass hulls to permit a minimum attenuation
of acoustic reply signals. Hulls of other type material types may
may be considered but most other hull types
will require that a Seachest design be built into the hull with an acoustic window across
across the face of the
enclosure (i.e. a significant hole must be cut out of the hull).
Inside mounting to the hull does minimize drag to allow faster survey
survey speeds, however, loss of
performance may result due to the attenuation loss in the hull.
Locate the transducer where the hull is solid fiberglass resin to
to maximize sound transmission. Do not
locate over balsa wood core material. Consult the hull manufacturer
manufacturer if you are unsure of the core
material or the best location. Never bond large resin housings directly
directly to the hull; always use a liquidliquidfilled box.
In any permanent installation the intended final configuration should
should be tested before it is implemented,
if possible.
For more information regarding the installation of a Seachest or other permanent transducer mount,
refer to our website at , or contact us directly.
Bathy-1500C Sensor Unit Electrical
WARNING: Be sure to turn the vessel power off at the main switchboard before proceeding with
the installation. If power is left on or turned on during the installation, then fire, electrical shock or
other serious injury may occur.
There are a minimum of 3 connections that need to be made to the BathyBathy-1500C Sensor Unit and the PC for the
system function properly. The user also has the option of connecting
connecting GPS, Heave Sensor, Hydrographic Software
Package and/or a Thermal Printer. The sections below describe the
the connection details for each.
All electrical connections to the BathyBathy-1500C Sensor unit are to the side of the unit. Refer to the sections
sections on each
individual connector for information on connector type, recommended
recommended cable and wiring specifics.
Bathy-1500C System Cables
The transducer connections for the Bathy-1500C will vary depending upon the needs of the
customer. In some applications (small boats, temporary installations) the Transducer(s) will
have the connector attached to the cable at the SyQwest manufacturing facility, if requested. In
more complicated installations, the transducer connectors will be supplied in kits along with
optional Junction boxes, and extension cables. This provides more flexibility to the user for
running cables and terminating the wires as needed. The Transducer cables, kits, and junction
boxes are all listed in Table below. Note, that these additional items are to be purchased or
supplied as required by the customer, so most but not all items are necessarily included in the
Bathy-1500C system.
Bathy-1500C DC Power Connection –J1
Before installing the power connection to the unit, the installer must first insure that the DC power
source is in the range of 10-30VDC and is capable of providing 50 watts of power to the unit. The
power source should also be able to provide an initial in-rush current greater than 50 watts. Due to the
high power amplifiers in the Bathy-1500C product, it is generally better to power the system with a
voltage that is greater than 20VDC if possible (lower current) although a 12V Battery will work fine
with the system. The Bathy-1500C Sensor unit is reverse polarity and over-voltage protected, however,
it is always required that the power mains be turned off during system wiring for both personal and
equipment safety.
The Power Cable supplied with the system is 10 feet long, and includes 3 conductors. The wires in the
power cable must be connected as follows:
– Positive DC Voltage (Fused Lead), DC IN+
BLACK – Negative DC Return, DC INWHITE (GREEN) – Earth Ground, SHLD
The DC Voltage lead includes a 10 Amp in-line Fuse. In the unlikely event that the fuse is blown it
should be replaced with a fuse of the same amperage. Installing an incorrect fuse can result in damage
or fire to the unit if it is not operating properly.
Bathy-1500C Data Interface Connection –J2
The Data Interface cable supplied with the Bathy-1500C is 10 feet long. It is a standard CAT5
Ethernet cable and should interface to any Ethernet port on a standard PC. The user will need
to setup the Ethernet port on the computer to support the fixed IP address associated with the
Bathy-1500C. Refer to the PC Software and Setup Section for instructions on how to
configure the PC Ethernet Port for operation with the Bathy-1500C.
If the 10 foot length of cable is not enough, the Data Interface Cable may be extended by using
an extension cable or a longer CAT5 cable can be purchased locally.
Bathy-1500C Transducer Connection J9, J11
The Bathy-1500C transducer connector is either hardwired directly to the transducer or connected to
the transducer through a Junction Box.
The standard transducer cable is 30 feet in length and has 2 conductors along with a shield thus, 3
connections are necessary for termination. Due to the wire AWG variations for different transducers,
a 7 and or 10 pin connector will be used to connect the transducer to the Bathy-1500C Sensor Unit. The
appropriate mating connector(s) will be supplied with the Bathy-1500C System. Only 3 of the pins on
the connector are wired to the unit, both wiring types are shown below. They are defined as:
Transducer +
Transducer –
Transducer Shield
The Transducer Connector on the Sensor Unit is shown below
Heave Input J4 and Firmware Download
Connection – J6 Audio Output Channel 1(J8)
and Channel 2 (J10)
The Heave input connection for the Bathy-1500C system is made via the 9 pin D connector, J4
on the Bathy-1500C Sensor Unit. The interface is a standard RS-232 connection running at
19.2KBaud. The Heave connection will require a user supplied 9 Pin D to 9 Pin D serial
connection cable.
The Firmware download connection for the Bathy-1500C system is made via the 9 pin D
connector, J6 on the Bathy-1500C Sensor Unit. The interface is a standard RS-232 connection
running at 115.2KBaud. The Firmware Download connection will require a user supplied 9 Pin
D to 9 Pin D serial connection cable. Further instructions on performing a Firmware download
are provided Firmware Flasher section of this manual.
The Audio output for each channel provides an analog signal that represents the raw analog
signal present at the A/D Converter in the system. Bathy-1500C users can use this output for a
variety of purposes but is most useful to investigate operational issues and also can be connected
to allow the logging of raw data from the system.
Bathy-1500C Host PC Electrical Connections
GPS Connection
Connecting a GPS or other Navigation
input to the PC running the Bathy1500C software allows the user to
store and annotate Date, Time, Position,
and Heading information to the
Acoustic data returns.
The Bathy-1500C PC Software supports
the NMEA 0183 protocol on a COM
port that is software selectable by the
user. When selecting a PC to use with
the Bathy-1500C system the user should
ensure that PC hardware supports
multiple COM Ports if a Navigation
input is desired. For Portable PC’s, a
PCMCIA COM port card can often be
used to provide a 2nd COM port.
The user should refer to the GPS
information in their GPS Manual as
well as the PC COM port wiring
information in their PC Manual to
