Chapter 1: DSM300 Installation
1.1 Introduction
This chapter provides details for mounting the DSM300 and connecting to the
display.
For the system to display depth, water temperature and speed, you must install
the transducer type(s) capable of transmitting the appropriate data. Transducer
information is provided in Chapter 2.
Planning the Installation
Before you install your system, plan the installation, considering:
• Correct transducer for your application, as described in Section 2.1
• Location of the sounder module, as described in Section 1.3
• Cable Runs, as described in Section 1.5
EMC Installation Guidelines
All Raymarine equipment and accessories are designed to the best industry
standards for use in the recreational marine environment.
Their design and manufacture conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to ensure that
performance is not compromised. Although every effort has been taken to ensure
that they will perform under all conditions, it is important to understand what
factors could affect the operation of the product.
The guidelines given here describe the conditions for optimum EMC performance,
but it is recognized that it may not be possible to meet all of these conditions in all
situations. To ensure the best possible conditions for EMC performance within the
constraints imposed by any location, always ensure the maximum separation
possible between different items of electrical equipment.
For optimum EMC performance, it is recommended that wherever possible:
• Raymarine equipment and cables connected to it are:
• At least 5 ft (1.5 m) from any equipment transmitting or cables carrying
radio signals, e.g., VHF radios, cables and antennas. In the case of SSB
radios, the distance should be increased to 7 ft (2 m).
