Installation
Red Sonar Engine Box
The Sonar Engine Box can be mounted in a convenient
location in the engine room, below decks, in a cabinet,
etc. It only needs accessibility for initial installation and
when/if you perform a software upgrade.
1) Select a location where the unit is protected from
excessive temperatures. Heat is one of the worst enemies
of electronic components, and will accelerate component
aging, thereby reducing the trouble-free life of your SE-
200.
2) Mount the SE-200 Sonar Engine box in a location
where it will be convenient to route the power cord and
transducer cable.
Connecting Transducer(s)
The SE-200 red sonar box has a black & white label on
the top. Looking down from the top of the box, there are
three 9-pin transducer connectors on the left end of the
box and several output connectors, a power I/O cable and
LED on the right end.
The sketch at right shows the three 9-pin transducer con-
nectors that are located on the left end panel. The three
connector retaining nuts are different colors which match
the color band on the correct transducer cable.
Notice that the vertical transducer cable always plugs into
the green connector. The SE-200A transducer has a
single vertical scan cable, so the blue and black connec-
tors are not used. The diagrams below at right show the
transducer connections for the various SE-200 configura-
tions.
