Unit installation

FS70 Trawl Sonar System
4 974-24007001/4.1
1.5 Processor Unit
The FS 70 19” Rack mounted Industrial Processing unit 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 FS 70 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.
