General description



1−6 GB 61 113 893 − 194 REV A

PC central unit

The PC central unit have the following minimum characteristics:

� a CPU with a performance id > 500 spec Int 2000,

� one AGP bus and two interconnection PCI bus,

� a RAM memory with 256 MB capacity,

� a hard drive with 40 GB capacity (minimum capacity), with the necessary soft-ware,

� an Ethernet 10/100 Base T interface (on PCI bus),

� a graphics interface on AGP bus.

VRAD card

The VRAD card is plugged into a PCI slot in the PC and provides an interface to surveil-lance radar with:

� a north reference pulse (ARP),

� increments (ACP),

� trigger,

� analogue and digital video signals.

The radar video signal is received by the VRAD card and undergoes the following opera-tions:

� digital encoding of the analogue signal,

� transfer to the CPU,

� conversion of the digitized signal to a pixel image which is transferred to the gra-phics interface for display.

The radar maintenance software allows the user to set all necessary parameters in orderto display the best possible radar video image.

The VRAD card has two connectors:

� an HD15 connector,

� and a DB25 connector.

The VRAD card is connected to the switching box by a cable terminated by HD 15 andBNC connectors.

MAIN FUNCTIONS

General

IRIS perform the display of air situation, made up of radar data

Operational functions

The operational functions of IRIS relate to the video display and radar maintenance.

For details of these functions and their user interface, refer to the Software User Manual.

Maintenance function

Internal maintenance is characterized by the Built−in Tests which are run at IRIS start−up.

These tests relate to the central unit (except the monitor, keyboard and mouse) and theradar video interface equipment.

As regards the VRAD card tests are initiated at start−up. These tests check the cardstatus. A green Light Emitting Diode (LED) at the rear (connector side) of the card comeson if the tests are successful. The green LED goes off if the tests fail.

Another test, with generation of a test pattern, is also offered.

PLINES BOX CONNECTION

General

The pLINES box provides multi−protocol serial communication to interface serial datato the Ethernet LAN.

The pLINES box is connected to:

� the Configured Computer by a network cable (see note) on ETH0, ETH1 or ETH2connector.

� radar ATCC serial outputs by a serial line.

This cable is a "straight cable".

The Ethernet connector of pLINES box is described in the table hereafter:

INITIAL SETTING−UP AND OPERATION

Initial setting−up

Refer to the manufacturer’s documentation for the installation before starting up thesystem.

After connecting the various components of the IRIS central unit, perform the followingsteps in order to start up the station:

Step Action

1 Switch on the monitor.

2 Switch on the pLINES box.

3 Switch on the computer.

During the self−test, the LED (green) on the VRAD−PCI card blinks. After the self−test, and if the VRAD−PCI is functioning correctly, the LED stays on a few seconds. In

the case of an anomaly, the led stays off.

To check, select the video test pattern command in the software interface (see IRISMaintenance Display General troubleshooting).

Start−up built−in tests

Internal maintenance is characterized by the built−in tests which are run at IRIS start−up.

These tests concern the PC (except the monitor, keyboard and mouse) and the VRADcard.

As regards the VRAD card off−line tests are initiated at start−up. These tests checkcard status. A green LED at the rear (connector side) of the card comes on if the testsare successful. The green LED goes off if the tests fail.

In case of a fault message:

Step Action

1 Analyse the fault message and record it in a LOG BOOK.

2 Check that the PC and peripheral are correctly power supplied.

3 Reboot the IRIS workstation as follows:

� switch off the unit,

� wait for 5 seconds,

� switch on the PC.

4 If abnormal operation occurs again, execute the maintenance operationsindicated by the anomaly message.

5 Diagnose faulty mouse or keyboard operation by inspection or exchange.In the case of the exchange of an LRU, switch off the workstation, removethe faulty LRU and install a new one. Then switch on the power to theworkstation.


General troubleshooting


5−6 GB 61 113 893 − 194 REV A

Step Action

6 If defective operation continues, refer to the manufacturer’s documenta-tion.

7 If poor operation still continues, diagnose the faulty computer operation.Refer to the manufacturer’s documentation.

8 If one of the LRUs is to be exchanged, carry out the following operations:

� switch off the workstation before removing the LRU,

� remove the defective LRU and replace it with a new one,

� switch on the workstation,

� check that the LED (green) on the VRAD card (at rear of computer)blinks and then stays on for several seconds. If in doubt, select thevideo test pattern in the software interface; the LED will come on aftertwenty seconds.

On−line test

An on−line test, with generation of a test pattern, is also offered:

Step Action

1 Select the "Radar Data" menu in the control window. Refer to IRIS UserManual.

2 To start or stop the radar video test pattern, left click on the "Radar videotest" button (disabled by default). This pattern is used to check the VRADequipment’s correct operation.

This procedure has to be performed when the configured computer has been replacedor the IRIS software changed or upgraded.

ASTERIX category 34 configuration

To succeed this operation, the user shall be familiar with Linux and "vi" editor.

Depending on the type of the radar configuration used, it should be necessary tochange a parameter in the aero.conf file.

This parameter indicates the size (in byte) of the item 034/050.

The default value is "6" which corresponds to an item 034/050 with all sub−fields (COM,PSR, SSR and MDS).

For a stand−alone Mode S radar the sub−fields transmitted should be COM and MDScorresponding to a value size of 4 bytes.

For a Mode S + PSR radar the sub−fields transmitted should be COM, PSR and MDScorresponding to a value size of 5 bytes.

The following table gives the size of 034/050 according the radar configuration:

Radar type Size of 034/050

Stand−alone PSR 3

Stand−alone SSR (or Mode S) 4

PSR + SSR (or Mode S) 5

Note




5−28 GB 61 113 893 − 194 REV A

To change this value:

Step Action

1 Do a CTRL+x to open an xterm window.

2 Enter VRADPCI as password.

3 Enter: cd IRIS_CURRENT/DATA/config

4 Edit the aero.conf file: vi aero.conf

5 Search the string "LongueurItemAst034_050:X" where X is the size value ofthe item 034/050.

6 Replace this value X by the correct value size.

7 Save the file.

8 Do a complete stop of IRIS by quitting the software and switching off.

9 Restart the IRIS.

Radar rotation speed configuration

To succeed this operation, the user shall be familiar with Linux and "vi" editor.

Depending on the type of the radar rotation speed, it should be necessary to changea parameter in the aero.conf file.

This parameter indicates the delay for track ageing.

The default value is "6 seconds" which corresponds to a rotation speed of 4 or 5seconds per scan.

We advise to set a value 20 to 50% higher than the radar scan duration.

Example: set 12 for a radar scan duration of 10 seconds.

To change this value:

Step Action

1 Do a CTRL+x to open an xterm window.

2 Enter VRADPCI as password.

3 Enter : cd IRIS_CURRENT/DATA/config

4 Edit the aero.conf file: vi aero.conf

5 Search the string "TrackAgingPeriodSec:X" where X is the delay for trackageing.

6 Replace this value X by the correct value.

7 Save the file.

8 Do a complete stop of IRIS by quitting the software and switching off.

9 Restart the IRIS.

Front face switches

The front face of the switching box has three manual switches:

� S1, to select either a primary or a secondary radar,

� S2, to select the treatment unit of the radar,

� S3, not used for the IRIS workstation (used to select Local terminal connection).
