Physical description
The ARGUS Radar System consists of the following units:
•
Monitor Unit on which the data, command buttons inside the SYSTEM DATA AREA, and the
echoes with relevant targets inside the PPI AREA are displayed.
•
Core Unit in which the ARGUS electronic boards are mounted.
• Keyboard Unit on which the hardware of the Control Panel is mounted.
• Scanner Unit – not included. Refer to Simrad ARGUS Radar Scanner – Technical Manual.
Monitor unit
The Argus Monitor Unit represents the visual interface between the Operator and the Equip-
ment. The equipment can be supplied with different types of Monitor Unit. Technical charac-
teristics are located in the next paragraph.
Control panel (keyboard)
The Control Panel is the interface on which the operator can insert data, change the working
parameters and perform the operations necessary for the correct use of the equipment.
The Control Panel features light indicators, pushbuttons, rotating knobs and a trackball, which
controls the equipment. For more details, refer to Chapter 2.
The Control Panel is connected to the Core Unit by means of a cable with connector.
Core unit
The Core Unit consists of the following main parts protected in a dedicated cabinet::
•
the Antares Assy
•
the Alpha Board
• the optional Alpha Expansion Board
• the Power Supply mounted on the Alpha Board
•
the Line Filter
•
the Main Power Switch
For details, refer to Simrad ARGUS Radar Installation & Service manual.
The boards are made up of multi-layers printed circuits using VLSI components; program-
mable gate arrays and microprocessors are used to achieve a high package density, functional
reliability and low power consumption.
Auxiliary indicators (Light Emitting Diodes) are also located on the boards to allow easy
scheduled test, troubleshooting and maintenance actions.
The Line Filter is fixed to the left lateral panel of the Core Unit by means of nuts. The supply
voltage (115 VAC – 220 VAC 50/60 Hz) is applied through the Main Power Switch to the Alpha
Board.
The Alpha Board is fixed on the left side of the Core Unit by means of screws. The board is
the interface between the Argus monitor, auxiliary navigation equipment (GYRO, GPS, LOG,
AIS…) and the TXRXs (transceivers) connected. The interconnection allows commands to be
transmitted or received through BNC connectors and the Terminal connectors.
General functioning description
The Argus monitor receives the following signals from the connected transceiver(s):
•
Video Signal
•
Trigger
• Azimuth (AZ)
• Heading Line (HL)
•
TXRX Data
The data is applied to the TXRX interface block of the Alpha Board that, upon command from
the Main Processor on the Antares Board, selects the transceiver to be used. The signals from
