DSM250 Digital Sounder Module Owner's Handbook Document number: 81211_1 Date: December 2002 DSM250 Digital Sounder Module iii DSM250 Digital Sounder Module Owner's Handbook December 2002 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 particular: HIGH VOLTAGE. The DSM250 contains high voltages. Adjustments require specialized service procedures and tools only available 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. iv DSM250 Digital Sounder Module 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 accessories 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, Chartplotter, 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 transducer 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 installation and operation of your new equipment. In order to obtain the best results in operation and performance, please read this handbook 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 displays 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. DSM250 Digital Sounder Module v Throughout this handbook, the dedicated (labelled) keys are shown in bold capitals; for example, MENU. The soft key functions, 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 handbook, 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.
