Transducer Connections
It is important that the two leads from the transducer or
transducers be connected to the correct connector on the
rear of the Twinscope . The label on the rear of the
Twinscope shows which transducer cable should be
connected to each of the two 9-pin connectors. If these
cables are reversed, the Twinscope will not scan
correctly.
The Twinscope can be purchased with either transom
mounted or thru-hull transducers.
The standard Twinscope single thru-hull transducer (T1-
I200-032) has two cables. Inside the transducer, one
cable connects to the array that does vertical scanning and
the other cable to the array that does the horizontal
scanning. These two cables are identified as either the
Probe (Vertical scanning) or Sea Scout (Horizontal
scanning) by a small label near the connector on each
cable. (see sketch at right)
The Twinscope can also use two seperate thru-hull
transducers - one for the Vertical scanning (Interphase
part number (T1-I200-026) and another for Horizontal
scanning (part number T1-I200-029). These transducers
can be identified by looking at the labels attached near the
connector on each cable.
For transom mount applications, the Twinscope uses two
seperate transducers, one for Vertical scanning (T1-0200-
025) and the other for Horizontal scanning (T1-0200-
028). These transducers can also be identified by
looking at the labels attached near the connector on each
cable.
The Transducer Installation Section, starting on page 12,
describes the procedures for properly installing the
Twinscope transducer(s) in the vessel.
