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 t ransducers are rated 60 or 75 ohms. Each has an 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 t hat 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 c omprise 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.
