Operator Station description
The Operator Station may be a panel computer or a separate computer with a display.
The computer is based on a commercial design,
but the software and hardware has been specified by
Kongsberg Maritime to suit the EA640 requirements.
WBT description
The WBT is provided to transmit acoustic energy through water. This transmission and
reception are commonly referred to as a
ping . After each transmission, the transceiver
receives the echoes from the targets in the water and/or the seabed. These echoes are
filtered and amplified, and then converted to digital format.
The Wide Band Transceiver (WBT) comprises a rugged
box providing all necessary transmitter and receiver
electronics. The receiver is designed for low noise,
and it can handle input signals spanning a very large
instantaneous dynamic amplitude range.
A high quality Ethernet cable connects the Wide Band
Transceiver (WBT) to the Operator Station. The distance between the Operator Station
and the transceiver can be extended up to maximum 70 meters. If a longer cable is
required, cut it in half, and insert an Ethernet switch to provide buffer amplification.
Note
If more than one Wide Band Transceiver (WBT) is used, a small high capacity Ethernet
switch is required to connect the transceivers to the Operator Station.
The Wide Band Transceiver (WBT) requires an external power supply offering 12 to
15 Vdc, minimum 5 A. A suitable power supply is provided with the delivery. The
transceiver can also be powered by a large capacity battery.
