1.1.3 Display Monitor
The display monitor for the FS 20/25 HP PC processor can be either a VGA “CRT”
or LCD Simrad ruggedized monitor, but any commercially available monitor may be
used. In order to have the full benefit of high resolution provided by the video Multi-
Display adapter available with the FS processors, you should use a Simrad LCD
Monitor.
1.1.4 Processor Unit
The FS 20/25 Series HP PC is the control unit for the system. The installed FS
20/25 system software processor 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 mouse click. A Remote Keypad is also available to simplify the operation of
the system.
The sector heading and width are also controlled by a single mouse click used to set
the center of the area to be scanned and the width of the sector scan, up to 360°, in
the polar mode.
The rear panel of the HP PC contains the connectors for AC power, Dual Monitor
port, or output for VCR recording, Serial A, Serial B port, Keyboard, Mouse, and
Printer, and Network port. The Network port can be used to connect the remote
workstation. Note: A security key (or “dongle”) must be attached to the parallel port
to enable full operation of the system.
1.1.5 Power Supply/TTM Interface Module
The FS 20/25 power supply assembly provides the high voltage required by the trawl
sonar. The DC output voltage is combined with the telemetry signals, and supplied
to the trawl sonar.
The long line power supply voltage and current are monitored by a voltage and
current meter, 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 and fuse are located on the rear panel of the TTM Module.
The TTM assembly is the interface that provides translation between the PC serial
port and the sonar telemetry communication protocol.
