DSM300 Installation Manual
1.5 Cable Runs
Consider the following before installing the system cables:
• You will need to attach power, transducer, and display cables.
• All cables should be adequately secured, protected from physical damage,
and protected from exposure to heat.
• Avoid running cables through bilges or doorways, or close to moving or hot
objects.
• Avoid sharp bends.
• Use a watertight feed-through wherever a cable passes through an exposed
bulkhead or deckhead.
• Secure cables in place using tie-wraps or lacing twine. Coil any extra cable
and tie it out of the way.
You will need to run the following cables:
•
Power cable
, supplied with the unit. This 10 ft (3 m) cable has a connector
plug at one end for connecting to the sounder module, and 3 wires at the other
end for connecting the power supply. The power cable may be extended by up
to 60 ft (20 m) using a wire gauge of AWG 12 or greater. The DSM300 is
intended for use on boat’s DC power systems rated from 10.7 V to 32 V.
•
Display cable
, used to connect the DSM300 to a display unit. A 3m-long
cable is included for connecting to a C Series display. Connection cables for E
Series or hsb
2
PLUS (Pathfinder) Series displays, or longer C Series cables, must
be purchased separately. See Table 1-1 “Cable Options“ on page 9 for a list of
available display cables.
•
Transducer cable
, supplied with the transducer. This 30 ft (10 m) cable has
a connector plug (with an outer nut that you must attach) at one end for the
sounder module or extension cable. Optional extension cables are listed in
Table 2-1 “Accessories“ on page 25.
CAUTION: Do Not Cut or Splice the Transducer Cable
• There is high voltage on the transducer cable. Splicing could
create a safety hazard.
• Cutting the transducer cable severely reduces sonar
performance. If the cable is cut, it must be replaced—it cannot
be repaired.
• Cutting the transducer cable will void the warranty and
invalidate the European CE mark.
