FS70 Trawl Sonar System
4 974-24007001/5.0
1.5 Processor Unit
The PC unit running the DATSS is the control unit for the system. The rear panel of the
Processing unit contains the connectors for AC power, Dual Monitor port, one Serial port
and several USB ports, Keyboard, Mouse, Printer, and Network port. The Network
Ethernet port can be used to connect the remote workstation or connect with the factory for
remote service support.
The installed DATSS system software provides a mechanism for the sonar head detection,
setup and operation. It is operated through the Main Control panel to enable the Sonar
selection, tilt, range, gain, cursor, and by moving the mouse pointer over the toolbar will
allow the operator to perform certain operations with a simple Right or Left mouse click.
The sector heading and width are also controlled by a single mouse click used to set the
center and the width of the sector scan. In polar mode the sector width can be extended up
to 360°.
NOTE: A security key or (“dongle”) must be attached to a USB port to enable full
operation of the system.
1.6 Power /TTM Interface Module
The FS 19” Rack mounted Power/TTM interface Module unit provides the supply voltage
required by the trawl sonar and the telemetry translation between the Processing Unit Serial
or USB port and the sonar head. The DC output voltage is combined with the telemetry
signals and supplied to the trawl sonar.
The voltage and current supplied to the sonar head are monitored by voltage and current
meters. A selector switch located below the voltage meter can be used to select the output
voltage of the power supply required for the appropriate system configuration. Also, a
separate on/off switch is located in the front panel.
NOTE: The main on/off switch input voltage selector and input fuse are located on
the rear panel of the TTM Module.
A test cable connector and selection switch between the trawl cable and test cable are
accessible on the front panel, providing quick access for a test cable without disconnecting
the 3
rd
wire cable from the rear of the TTM.
1.7 Deployment Housing Unit
The trawl deployment housing unit is made from polyurethane and designed for the
harshest of environments yet it is easy to handle. The FS 70 trawl unit sits within the
