PC Transceiver
The PC Transceiver comprises a complete dual frequency
single beam system on a computer circuit board. The PCT fits
inside the echo sounder unit, and it is powered directly from the
sounder’s internal power supply. Only one PCT board can be
installed. On a new system, the PC Transceiver is installed and
tested by Simrad prior to delivery. There are no need for the
user to open the echo sounder cabinet.
The PC Transceiver is available in two configurations. Both are
designed for the fishery community:
• PCT-S38(1)/S200(1)-F
- This circuit board contains a single beam 38 kHz 1 kW
channel, and a single beam 200 kHz 1 kW channel.
• PCT-S50(1)/S200(1)-F
- This circuit board contains a single beam 50 kHz 1 kW
channel, and a single beam 200 kHz 1 kW channel.
General Purpose Transceiver
The General Purpose Transceiver (GPT) is a small
self-contained unit containing its own power supply. It operates
from +12 Vdc or 115-230 Vac. The unit can be mounted
anywhere on board the ship, provided that the location is dry
and ventilated. Power cable and mounting brackets are enclosed.
We recommend that the GPT is mounted as close to the
transducer(s) as possible.
The GPT for the EQ60 is only available in single beam
configuration. However, a dual frequency single beam
configuration is provided. Possible operating frequencies are 12,
18, 27, 38, 50, 70, 120 and 200 kHz.
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-S38(1)/S50(1)-F (single beam 38 and 50 kHz, 1+1 kW)
Two or more General Purpose Transceivers (GPT) can exist on
the same Ethernet cable. A multi-frequency sounder emerges
simply by using several transceivers on the Ethernet cable.
It is even possible to combine one internal PC Transceiver with
a number of external General Purpose Transceivers.
