Installation manual

Simrad ES60
A large number of transducers are available. There are several
transducer alternatives for each operating frequency with
different beam widths, power rating and mounting arrangements.
All transducers are rated 60 or 75 ohms. Each has a n efficiency
of approximately 50%.

General Purpose Transceiver (GPT)
One or more General Purpose Transceivers (GPT) are included.
A single frequency General Purpose Transceiver accepts one
transducer, while a dual frequency transceiver accepts two
transducers.
The General Purpose Tra
nsceiver is a small self-contained unit
containing its own po
wer supply. It operates on + 12 Vdc or
115-230 Vac. The uni
t can be mounted anywhere on board
the ship, provi
ded that the location is dry and ventilated We
recommend th
at it is mounted as close to the transducer(s) as
possible. P
ower cable and mounting brackets are enclosed.
An Ethernet link connects the General Purpose Transceiver
to the Processor Unit (computer). This link may comprise a
standard Ethernet cable and - if necessary - an Ethernet switch.
The transceiver includes its own Ethernet interface. A network
interface board must be fitted to the computer.
The General Purpose Transceiver is available in single beam
and split beam configurations. A dual frequency single
beam configuration is also provided. The possible operating
frequencies are listed in the technical specifications. Typical
configurations include:
• GPT-S38(4)-F (single beam 38 kHz, 4 kW)
• GPT-S50(4)-F (single beam 50 kHz, 4 kW)
• GPT-S70(1)-F (single beam 70 kHz, 1 kW)
• GPT-S120(1)-F (single beam 120 kHz, 1 kW)
• GPT-S200(1)-F (single beam 200 kHz, 1 kW)
• GPT-Q38(4)-F (quad (split) beam 38 kHz, 4 kW)
• GPT-Q120(4)-F (quad (split) beam 120 kHz, 4 kW)
• GPT-S38(1)/S50(1)-F (single beam 38 and 50 kHz, 1+1 kW)
Two or more General Purpose Transceivers can exist on the same
Ethernet cable. A multi-frequency sounder emerges simply by
using several transceivers on the Ethernet cable.
