Intended Use
Raymarine DSM250 Digital Sounder Modules provide echo
sounder data that can be displayed on Raymarine PLUS Radar,
Chartplotter, or Fishfinder display units. DSM250 Digital
Sounder Modules are intended for recreational depth finding and
fishfinding purposes.
SAFETY NOTICES
This equipment must be installed and operated in accordance with
the instructions contained in this manual. Failure to do so can
result in personal injury and/or navigational inaccuracies. In par-
ticular:
HIGH VOLTAGE. The DSM250 contains high voltages. Adjust-
ments require specialized service procedures and tools only avail-
able to qualified service technicians – there are no user
serviceable parts or adjustments. The operator should never
remove the cover or attempt to service the equipment.
CAUTION:
Removing the transducer cable from the rear of the DSM250
while the sounder module is powered on can cause sparks. Only
remove the transducer cable after power has been removed from
the DSM250. As with any electronic device, be sure the sounder
module is mounted where it is well ventilated and free from
gasoline fumes.
If the transducer cable is accidentally removed while the DSM250
is powered on, remove power from the sounder module, replace
the transducer cable, and then return power to the module. As a
safety feature, the DSM250 only recognizes that the transducer is
connected at power-up.

EMC Conformance
All Raymarine equipment and accessories are designed to the best
industry standards for use in the recreational marine environment.
The design and manufacture of Raymarine equipment and acces-
sories conform to the appropriate Electromagnetic Compatibility
(EMC) standards, but correct installation is required to ensure that
performance is not compromised.
Preface
This handbook describes the Raymarine DSM250 Digital
Sounder Module (200/50 kHz).
This device must be connected to an
hsb2
PLUS Radar, Chartplot-
ter, or Fishfinder display unit to show echo sounder data. The
DSM250 will not work with older HSB (non-PLUS) displays.
Note: Older HSB (non-PLUS) display units must be upgraded to
hsb2
before they can function with the DSM250.
Echo sounder systems require an appropriate Raymarine trans-
ducer unit and inter-connecting cable. Details for selecting and
installing the transducer are described in document number
81196, Transducers for Fishfinders Owner’s Handbook.
This handbook contains very important information on the instal-
lation and operation of your new equipment. In order to obtain the
best results in operation and performance, please read this hand-
book thoroughly.
Raymarine’s Technical Services representatives or your local
dealer will be available to answer any questions you may have.
Conventions
Raymarine echo sounding (sonar) devices with integrated dis-
plays are known as Fishfinders. In this document, the DSM250—
which does not have its own display—is alternatively called a
Digital Sounder Module, Sounder, or just Module. The DSM250’s
image data can be viewed on a display unit when that display is in
Sonar Mode.

Throughout this handbook, the dedicated (labelled) keys are
shown in bold capitals; for example, MENU. The soft key func-
tions, menu names and options are shown in normal capitals; for
example, SCREEN.
Operating procedures, which may consist of a single key-press or
a sequence of numbered steps, are indicated by a ➤symbol in the
margin. When the procedure requires you to press a soft key, the
soft key icon is shown in the margin.
Technical Accuracy
The technical and graphical information contained in this hand-
book, to the best of our knowledge, was correct as it went to press.
However, the Raymarine policy of continuous improvement and
updating may change product specifications without prior notice.
As a result, unavoidable differences between the product and
handbook may occur from time to time, for which liability cannot
be accepted by Raymarine.
Warranty
To register your DSM250 Digital Sounder Module ownership,
please take a few minutes to fill out the warranty registration card
found at the end of this handbook. It is very important that you
complete the owner information and return the card to the factory
in order to receive full warranty benefits.
