ES18 Connecting to a 12-pin Amphenol
socket
The Simrad ES18 is a split-beam transducer designed for fish finding and underwater
science applications. The transducer is connected to terminals
A
through
N
on a circular
12-pin Amphenol socket (Type 97-12-19S). This socket is used on the General Purpose
Transceiver (GPT), and on several versions of the Wide Band Transceiver (WBT).
The other end of the cable is permanently fixed to the
transducer.
The transducer is designed with the individual elements
organized in four separate sectors. It is very important
that the transducer is correctly installed with the sectors
positioned as shown in the illustration (seen from
above). Each sector is connected to a dedicated transceiver channel. In this context,
the phrase
transceiver channel is used to describe one single pathway through the
transceiver. This pathway contains one transmitter, one preamplifier and the necessary
transmit/receive switching circuitry.
Note
We strongly recommend that you install the transducer cable in a steel conduit.
Depending on production date, the transducer can be delivered with two different cable
types. On older transducers the cable contains black and white conductors. On new
transducers the cable contains colour coded conductors.
