18 DSM25 Owner’s Handbook
2.3 Optional Equipment
If a longer connection is required from the DSM to the display, you can purchase
one of the following A65 Network Cables from Raymarine. Be sure to install the
suppression ferrites, if supplied.
2.4 Selecting Sounder Module Mounting Location
The DSM25 is waterproof to IPX-7 is and is designed to be mounted either above
or below deck.
Mount the DSM25 where it is:
• protected from physical damage and excessive vibration
• protected from prolonged exposure to rain, salt spray and direct sunlight
• well ventilated
• as close to the transducer as possible
Do not locate the DSM25:
• in the engine compartment
• on the main console
When planning the installation, the following should be considered to ensure
reliable and trouble free operation:
•
Access: There must be sufficient space below the unit to enable cable con-
nections to the panel connectors, avoiding tight bends in the cable.
•
Interference: The selected location should be far enough away from
devices that may cause interference, such as motors, generators, and radio
transmitter/receivers. (See “EMC Conformance“ on page 8.)
•
Magnetic compass: Mount the unit at least 3 ft (1 m) away from a magnetic
compass.
•
Cable runs: The unit must be located near the A65 display. The cable sup-
plied is 11.5 ft (3.5 m) in length. Longer network cables are available as
described in Section 2.3.
•
Environment: Good ventilation is required to prevent the unit from over-
heating.
