Software InstallationRVP8 User’s ManualApril 2003A–1A. Software: Basics, Installation and BackupA.1 OverviewThe RVP8 and RCP8 are implemented using standard PCI components with some custom cardssupplied by SIGMET. While seemingly very different products, these actually have very similarhardware and software. The software installation, configuration and backup/recovery proceduresare nearly identical. For this reason, this appendix is written to cover both the RVP8 and RCP8.This appendix covers the following topics:Login, logout and shutdown Section A.2Software installation Section A.3Software configuration Section A.4System backup/recovery Section A.5Software upgrade Section A.6Network basics Section A.7Your system is shipped with all software installed so you are really ready to start using the unitimmediately after opening the box. You should read this appendix to become familiar with thegeneral operating procedures, especially the system backup procedures which will help you ifyou ever need to re-install the software after a disaster or install an upgrade provided bySIGMET.Other references related to the software are:RVP8 Programmer’s Manual: Describes the development environment, publicsource and API’s provided by SIGMET.IRIS Utilities Manual: Describes utilities for radar calibration, test andmaintenance that are shipped with the RVP8 and RCP8
Software InstallationRVP8 User’s ManualApril 2003A–2A.2 Basics of Login, Logout and ShutdownThe RVP8 and RCP8 both use the Linux operating system and X–Windows. When logging intothe RVP8 either locally or over the network via “telnet” you will need to supply a user name andpassword. The system is tolerant of the AC power being suddenly turned-off, but in general it isrecommended to follow a power-off shutdown procedure. These procedures are described in thissection.Important: For network security reasons, both the RVP8 and RCP8 are shippedwith remote access disabled. To learn how to enable telnet, refer to the end ofSection A.7.2.A.2.1 Power up procedureThe power switch is located on the lower right front of the unit. When you power the unit on,the RVP8 goes through an automatic startup of the operating system at the end of which theRVP8 software and performs power–up self tests. This is described in detail in Section 2.3.5.If you are not doing any diagnostic or software maintenance work on the system, there is noneed to log-in after power-up; simply turn the unit on and your application software will takeover. No operator intervention is required. However, to perform maintenance functions such assoftware upgrades, testing and backup/recovery, you will need to log-in.A.2.2 Local and remote loginThere are two ways to login to the RVP8:Local login: The local keyboard, mouse and monitor can be used. Note theseoften are not connected on operational systems. SIGMET provides a keyboardand mouse with each system. The monitor is optional and may be provided by thecustomer, to SIGMET specification. Most VGA monitors will work.Remote login: If telnet is enabled you can use this for remote access. Checkwith your network administrator.For the remainder of this discussion it is assumed that local login is used.A.2.3 Default operator and root login passwordsThere are two default users defined in the standard software installation:”root” with password ”xxxxxxxx” (8 lower case x’s). This is for OperatingSystem maintenance functions.”operator”with password ”xxxxxx” (6 lower case x’s). This is for RVP8application software maintenance functions. For a complete list of supportedutilities see Section 1.6. These are all described in detail in the IRIS UtilitiesManual.
Software InstallationRVP8 User’s ManualApril 2003A–3Your system administrator can change either of these passwords by using standard Linuxpassword support.A.2.4 Login procedure Local login as operator after power-upConnect keyboard, mouse and monitor and then cycle power on the system toforce a reboot. This causes Linux to recognize these devices on power-up.At the power-up “login” prompt type “operator” and press Enter. Whenprompted, provide the appropriate password (factory default is “xxxxxx”, 6 lowercase x’s).Logging-in as operator you will be taken to an X-Window screen.Right-click the mouse and select “New Window” to get a terminal window.The top of the terminal window shows, for example:operator on rvp8–1 : /home/operatori.e., your user name, the node name of the system and the current directory path. If you would like to have a terminal with a bigger font, you can type “sigterm”.Switching from operator to root login using su"The easiest way to switch to a root login for system administration work is to type the super usercommand “su” and then give the root password. The prompt will change from $ to # indicatingthat you are root.Exiting su" root login to return to operatorIn an X–terminal where you have become the “super user (su)”, simply type “exit” to return tooperator. The prompt will change from # to $.Local root login after powerup To login as root after a power–up or after exiting X–Windows, simply type “root” and pressEnter at the login prompt, then give the appropriate password (factory default is “xxxxxxxx”, 8lower case x’s).You will be in a full screen terminal. This is not as convenient as X–Windows since only oneterminal can be displayed on the screen.If you need a second full screen terminal type “Alt-F2”. You can return to youroriginal terminal by typing “Alt-F1”. The other function keys can provideadditional terminals.
Software InstallationRVP8 User’s ManualApril 2003A–4A.2.5 Logout procedure Logout from XWindowsMethod 1: Right-click the mouse and select “Exit”.Method 2: Simultaneously click “Ctrl-Alt-Backspace”.You will be logged out and the screen will show the initial login prompt. on the full screenterminal.Root Logout from full screen terminalIf you logged–in as root from the power-up full screen terminal,A.2.6 Poweroff shutdown procedure If you need to swap PCI cards in the chassis, you must first do a poweroffshutdown as described here..As either operator or root type “poweroff”. The system will go through a shutdown sequence.When it is done “Power down” will be displayed. At this point you can press the power switchlocated on the right lower front of the chassis.
Software InstallationRVP8 User’s ManualApril 2003A–5A.3 Software InstallationA.3.1 When to perform software installationWhen your unit arrives, it is shipped with all software installed. Therefore, software installationis usually not necessary at the initial installation. There are two occasions when you might wantto re-install the software:Installation of a new CDROM release from SIGMET.Recovery in the event of disk corruption or failure.A.3.2 Preparing for the installationThe following should be done before you perform the software installation:Either locate or, if possible, make a backup of your custom configuration files perSection A.5. If you have made a backup in advance, then you will make there–installation much easier.Locate your software installation CDROM that was originally supplied bySIGMET or perhaps you will perform an installation of an upgraded versionsupplied by SIGMET. In the event that you need a software installation CDROM,contact SIGMET (support@sigmet.com). These are provided free of charge bySIGMET. However, the specific version that was originally shipped with yoursystem may no longer be available. In this case you will install an updatedversion.Make sure that all PCI cards are properly installed.From the “as-Built” documentation that is supplied with your system, verify thetype of motherboard or SBC that is installed. If you cannot locate this, then youcan check directly on the board itself by removing the top cover of the unit. Forexample, the Super Micro G2 motherboard is labeled in the rear left part of theboard (relative to the front of the chassis). You may need a flashlight to read:Super P4DPE–G2Connect the connector panel to the I/O-62 via the cable that is provided.Connect the keyboard, mouse and monitor. Note that the VGA monitor istypically supplied by the customer.For the RVP8, the IFD should be installed and powered so that it can pass its selftests later in the procedure. If an external reference clock is used for the IFD, thenthis should be active so that the unit can pass self tests.For complete information on hardware installation see Section 2.Once you have completed these steps, go to Section A.3.3 below.
Software InstallationRVP8 User’s ManualApril 2003A–6A.3.3 Installing the system softwareAfter you have prepared for the installation, as described in the previous section, you are readyto install the software.Initial software installation stepsReady the unit with keyboard, mouse, monitor, etc. as described in the previoussection.Switch the power on using the switch on the lower right front of the unit.Press the eject button on the CDROM drive and when it opens, insert the RDACDROM into the drive.When prompted, press Del to enter the setup (lower right of number pad).Hint: If you get too busy inserting the CDROM and miss the BIOS setupprompt, simply power the unit off and on to start again, this time with theCDROM already in the drive.Setting the BIOSIf the BIOS has been configured already during a previous installation or at thefactory, then you should skip this step.Note that specific BIOS keystrokes and menus often change. Use this section as ageneral guide.Reset to Defaults: In the BIOS setup, reset BIOS to default parameters. This istypically done by pressing F9 or in the Exit section and then confirming theYES/NO question.Set Time: In the Main section, set the system time and date to UTC. This is a 24hour clock (8:00 pm = 20:00).Enable Floppy: In the Main section, set Legacy Diskette A: 1.44MB 3.5”.Set Device Boot Order: In the Boot section, select the boot order to be:CDROMFloppy (sometimes listed under “Removable Devices”)Hard DriveSelect SAVE and EXIT. The unit will reboot automatically from the CDROM.

If prompted with: “Would you like to initialize this drive?”, select YES (using the TAB key) and then select ENTER.After about 10 minutes, the CDROM ejects. Remove it. The PC rebootsautomatically. Continue to next section.Installation steps to enable automatic startup of the RDA softwareAt login prompt, login as: “root” and password “xxxxxxxx” (8 x’s)If you are installing an RVP8, type:chkconfig ––level 2345 dspexport_init onchkconfig ––level 016 dspexport_init offchkconfig ––level 2345 rvp8_init onIf you are installing an RCP8, type:chkconfig ––level 2345 rcp8_init onLogout of root by typing “exit”.
Software InstallationRVP8 User’s ManualApril 2003A–8Installation steps to “flash” FPGA’s in SIGMET devicesIn this section you will be installing FPGA software into each of the SIGMET components. Youwill need to make an inventory of what is in your system and then issue an “rdaflash” commandto each one as described below:Login as “operator” with password “xxxxxx” (6 x’s)You will enter X–Windows. Right click the mouse and start a terminal window.For each SIGMET component (italic) type the appropriate command (bold):SIGMET Component Unit ID If RVP8, type:Standard RVP8/Rx Card –0rdaflash –program rvp8rx–0Standard I/O–62 Card –0rdaflash –program io62–0Standard Connector Panel –0rdaflash –program io62cp–0Optional RVP8/Tx Card –0rdaflash –program rvp8tx–0Optional 2nd RVP8/Rx –1rdaflash –program rvp8rx–1If RCP8, type:Standard I/O–62 Card –0rdaflash –program io62–0Standard Connector Panel –0rdaflash –program io62cp–0Do a system shutdown by typing “poweroff”When “Power down” is displayed, turn power off with power switch on lowerright of front panel.This completes the FPGA software installation.
Software InstallationRVP8 User’s ManualApril 2003A–9Reboot power-up check and RDA diagnosticsAfter you have completed the installation steps above, you should reboot the unit. You canobserve the progress of the reboot on the monitor. In addition, the front panel LED display willshow the time of the reboot and display diagnostic messages. Typically about 1 minute isrequired for the system to complete reboot.After the reboot is completed:Verify that the front panel LED display does not indicate any faults.Log-in as operator, run dspx and issue the “v” command. Check the resultsagainst the example in Section 3.1.4. Note that both the IFD and connector panelshould be installed and connected.

Software InstallationRVP8 User’s ManualApril 2003A–10A.4 System Software ConfigurationAfter the receiving your unit from the factory, or after software re–installation, there are severalconfiguration steps required to customize your system for your particular environment andapplication. The configuration tools available for this are summarized in the table below.ConfigurationToolRDADeviceDescription of Configuration Featuressetup utilitysetup_dsp.confRVP8 Configures the local environment required to run RVP8 the support utilitiessuch as ascope and dspx. Examples include radar equation parametersthat are required for calibration, pulse width definitions and PRF requestlimits.setup_ant.conf RCP8 Configures the local environment required to run the RCP8 support utilitiesthat such as antenna or bitex. Examples include, max allowed AZ/EL velocity request, MIN and MAX elevation angles that can be requested andLAT/LON of radar for sun tracking.TTY setupsrvp8.confRVP8 Defines the details of the sampling and processing algorithms as well asthe operational configuration of the system. Examples include, IF filter design and selection, PRF limits, relative trigger timing, dual polarization features.rcp8.conf RCP8 Used to configure which status and control bits are available and define theantenna servo control parameters. Examples include, physical or virtualtachometer selection, shutdown safety criteria and internal antenna simulator on/off.softplane.conf RVP8 File that is edited which defines the various I/O signals on the I/O62 connector panel, pinbypin. For example, whether a line is an input or output,RCP8nector panel, pin by pin. For example, whether a line is an input or output,electrical spec such as RS422 or TTL, what local variable name is associated with each line.Important: Both the setup utility and the TTY setups must be configured tocustomize your system. This is part of the installation procedure.All of the configuration results are stored as ASCII text “.conf” files, typically in a directorycalled /usr/sigmet/ (factory default). The file names are indicated in the table above. Each filehas a factory default configuration file that is stored in the template directory (the default is/usr/sigmet/config_template/init/). An advantage of this approach is that for a radar networkwith identical hardware, configuration maintenance can be performed by copying pre-tested filesover the network.The following serve as references and are not repeated here:setup utility IRIS Utilities ManualRVP8 TTY setups RVP8 User’s ManualRCP8 TTY setups RCP8 User’s ManualThe configuration of the softplane.conf file is described below.
Software InstallationRVP8 User’s ManualApril 2003A–11A.4.1 Configuring the softplane.conf file What is the softplane.conf file ?The softplane.conf file is used to define pin–by–pin assignment of I/O functions to variousconnectors on the I/O-62 connector panel. It is a plain text ASCII file that is self-documented.Since the RVP8 and RCP8 have virtually no jumpers, or wirewrap, all I/O configuration on theI/O-62 connector panel is done by software approach according to this file.Where is softplane.conf ?The file resides in the IRIS_CONFIG directory. Typically this is /usr/sigmet/config (this is thedefault directory that is factory installed). The factory configurations are also available in the/usr/sigmet/template/init directory so that you can always return to the factory defaults if youneed to.When do I need to change softplane.conf ?The softplane.conf file that is shipped with your system is configured for a standard connectorpanel with I/O as described in Appendix B. As long as you use the standard I/O pinassignments, then you do not need to change softplane.conf.If you need to redefine some of the I/O pins on the connector panel, or add additional SIGMETcards such as a second I/O-62 then you must change softplane.conf.Editing softplane.confYou will need to use a text editor to modify the softplane.conf file. There are two editorsincluded in the system:vi The generic UNIX editor that is available on every UNIX system.It is really arcane to use, but many people know how to use it out of necessity orthey are simply used to it now.emacs: This is more user friendly with keyboard commands and mousesupport when you are in X–Windows so it a little easier to learn than vi.If you are not familiar with either of these, then you will need to either find someone who is orlearn how to use these tools.To start an editing session you would do the following as operator:$ cd /usr/sigmet/config$ vi softplane.conforemacs softplane.conf

Software InstallationRVP8 User’s ManualApril 2003A–14softplane. conf organization and syntaxThe softplane.conf file is used to define every I/O pin on every connector, on the PCI cardsthemselves and on the connector panel. There are two primary definitions that are made for eachpin:Physical interface- the electrical properties (RS422 output, analog input, TTLoutput, etc.).Logical interface- The internal variable name that is associated with each pin.With this in mind, we can describe the syntax of the file.“#” at the beginning of a line indicates a comment. These are used for internaldocumentation and if you make changes you should comment them, for example# TTL I/O on J7## Modification by REP on 2 Apr 03# Added new interlock input on connector panel J7 pin07...The top part of the file provides a list of internal variables names that are used todefine the logical interface to the softplane. These are divided into status inputs(also called indicators) and control outputs (also called requests). For example,sPedAZ0 corresponds to the LSB of a digital azimuth angle relative to theantenna pedestal. The tables on the next page provide a summary of the availablestatus and control variable names.Important: This table is subject to changeEach definition line in the file starts with the keyword text:# splConfig...The first un-commented line of the file indicates the version of the IRIS supportsoftware that was last used to machine–generate the file. This is an informationonly field for traceability purposes and is thus not edited. In the example we havethis shown as: # splConfig.sVersion = ”7.32”

Software InstallationRVP8 User’s ManualApril 2003A–17A.5 System Backup and RecoveryBecause both the operating system and the RDA software are contained on the RDA CDROM,in the event of a serious failure, the complete software is simply re-installed from scratch. Thereare however, a few files that contain your custom configurations. In general these are files in the/usr/sigmet/config directory and the /etc directory. In fact, since they are all simple text files,they will, in most cases, fit onto a 1.44 MB 3.5” floppy diskette.SIGMET provides two utilities for backup/restore:rda_backup- finds all files modified after the original installation (orre–installation), puts them into a compressed UNIX “tar” file and copies the resultto either a floppy disk or a directory on the hard disk. System created files indirectories such as /tmp and /var are excluded from the backup.rda_restore- restores the contents of a backup tar file from floppy disk to the harddisk to the RVP8.In the case where the backup tar file is written to a directory on the hard disk, the user can thenuse ftp to put it on another computer on the network, or alternatively, put the file on CDROMvia the CDRW device. This section describes the use of the rda_backup and rda_restore utilities.A.5.1 System BackupWhen to make a backupYou should make a backup whenever you have made a change to the configuration of yoursystem: Examples include:Changing softplane.conf or other .conf files in /usr/sigmet/config.Changing files related to networking or security in /etc.SIGMET does not recommend that you attempt to backup individual files. Instead you shoulduse the backup procedure described here since it will make the restore much easier, plus youmight miss something important that rda_backup will find.Backup MediaThere are two primary media for backup:1.44 MB floppy disk drive (FDD)A directory on the local hard disk drive (HDD)In most cases you will use the 1.44 MB FDD approach. You would backup to an HDD directoryin the event that a backup, because it is too large, fails on the floppy . If you use the HDD approach you must either transfer the backup to aCDROM via the CDRW, or use ftp to copy files to another machine. See SectionA.5.3 for the procedure.The next two sections describe how to prepare these two media.
Software InstallationRVP8 User’s ManualApril 2003A–18Preparing the floppy backup media Every time you backup, you should use a freshly formatted floppy. It is possible to have severalbackups on a single floppy, but this is a bit risky if that diskette fails. Indeed some systemmanagers even make two backups for added security. This is a smart thing to do.There are three ways to format a floppy:Purchase formatted floppies. This is the easy way.Format the floppy on a Windows machine. Simply select the floppy drive(usually A:) under “My Computer” and then right click the mouse to select“Format”Use Linux to format the floppy. The command (as root) is:# mkfs.msdos –v –n RVPBACKUP /dev/fd0Here the text RVPBACKUP serves as the DOS volume label for the floppy. For and RCP8 usethe text RCPBACKUP. You can use other text if you want, but do it in upper case with no spacesor special characters. It is also assumed that the floppy drive is /dev/fd0.After you have a formatted floppy, the next thing to do is to LABEL IT, for example, write onthe labelRVPDate e.g.,YYMMDD
Software InstallationRVP8 User’s ManualApril 2003A–19Mounting the floppy backup media Insert the floppy disk into the drive and then mount it (first use the su command to becomeroot):$ suPassword:# mount /dev/fd0 /mnt/floppyIf there is a problem with this, check that there is a directory called /mnt/floppy. If not, create itas root with:# mkdir /mnt/floppyIt is a good idea to make sure that the floppy does not contain anything from a previous backupthat you want so after you mount it check it with:# cd /mnt/floppy# ls –alsIf the floppy disk contains files from a previous backup that you want to keep, select anotherdisk.Preparing a hard disk backup directoryIn the case that you are using a directory on the hard disk, as operator create a directory such as/tmp/backup.$ cd /tmp$ mkdir backupBackup files will be written to this directory with unique, machine generated file names thatcontain the YYMMDDHHMMSS time code.
Software InstallationRVP8 User’s ManualApril 2003A–20Running rda_backupAfter the media has been prepared and mounted (in the case of an FDD), then simply type thecommand:$ rda_backup –v /mnt/floppyfor floppy disk back-upIn the case of a hard disk backup to a directory such as /tmp/backup you would type:$ rda_backup –v /tmp/backupfor hard disk backupThe rda_backup utility will then check all of the directories where you have likely madeconfiguration file changes. Any files that were modified since the original installation will beincluded in the backup.If you use the –v option when starting rda_backup, then a listing of files will be displayed onthe terminal. When the backup is complete, the terminal will show:...Backup Complete: <File name> 0.9 MB 20 Files$Un-mounting and removing the floppyTo unmount the floppy, become root via the “su” command and type:$ suPassword:# cd /# umount /dev/fd0You may now push the eject button on the front of the drive to remove the floppy. Double checkthat it is labeled with the proper date.The most common problem encountered when un-mounting is that the FDD is “in use”. Thismeans that a terminal is in the /mnt/floppy directory. Typing “cd /” will take a terminal out ofthe FDD directory.
Software InstallationRVP8 User’s ManualApril 2003A–21A.5.2 System RecoveryRecovering an entire systemIn the event that your system becomes “un–bootable” perhaps because of a disk failure orcorruption, you will simply re–install the entire system per Section A.3.3, and then use yourrda_backup floppy disk and the rda_restore utility to recover your custom configuration files.Recovering the configuration files is described below:In the event of a hard disk failure, you will first need to replace the standardIDE hard disk before attempting to recover your system. Most computer storeswill carry such a disk or you can contact support@sigmet.com to purchase anew one.Mounting the floppy or CDROMIf you are recovering from a floppy drive or CDROM, then you must first mount these devices.Mounting the floppy is described in Section A.5.1.Mounting the CDROM is described in Section A.6.5.You must be root to mount devices. Use the “su” command to switch fromoperator to root. Type “exit” to switch back to operator.After the floppy is mounted, you should check to verify that the backup file that you want isindeed on the disk. Do this as follows:$ cd /mnt/floppy$ ls –alsThis will give you a listing of files on the floppy. The procedure for a CDROM is the sameexcept the device is /mnt/cdrom.Running rda_restoreAfter the media has been mounted, run the rda_restore utility as operator. In the examplebelow, it is assumed that the device is /mnt/floppy.$ rda_restore –v /mnt/floppyOther possible devices are a CDROM (e.g., /mnt/cdrom) or a hard disk drive directory (e.g.,/tmp/backup). The –v command will provide a list of all files that were restored. At the end ofthe restore you will get a message:...Restore Complete <filename> 0.9 MB 20 Files$All that remains is to unmount and remove the floppy (this is done as root) as described below.
Software InstallationRVP8 User’s ManualApril 2003A–22Un-mounting and removing the floppy or CDROMIn the case of a floppy, become root and then issue the “umount” command:$ suPassword:# cd /# umount /dev/fd0 (Note: spelling is indeed “umount”)You may now push the button to eject the floppy.For a CDROM, you can use the eject command (instead of “umount”):# ejectThis completes the restoration of your custom configuration files.A.5.3 Transferring a backup file from the RVP8 hard diskIf you used rda_backup to make a backup file on the hard disk (e.g., in the /tmp/backupdirectory), then you need to transfer this file to another medium for safety in case the hard diskfails. There are three options:ftp to another networked computerCopy to the floppyCopy to the CDROMThese are described below.ftp to another computerThis assumes that there is another computer on the network, that you know its IP address or it isconfigured in your /etc/hosts file and that the security settings on the other computer permit ftp.Check with your network manager to verify these criteria.For this example, it is assumed that you made your backup to a directory called /tmp/backup andthat you are going to send it to another computer in the /tmp directory. To copy the backup filelogin as operator and in an X-Terminal type:$ cd /tmp/backup(or use the actual directory if different)$ la –als(to view the files in the directory)Identify the file that you want to transfer via ftp and write down its name, then:$ ftp <hostname or IP address>ftp> cd /tmpftp> put <filename of backup in /tmp/backup>ftp> quit$The backup file is now on the other computer in the directory /tmp
Software InstallationRVP8 User’s ManualApril 2003A–23Copy to a floppyFirst check the size of the backup file to determine if it will fit on a floppy. To do this for backupfiles stored in /tmp/backup:$ cd /tmp/backup$ ls –alsThe file size in bytes is shown just to the left of the date column. To fit on a floppy the backupfile that you want to copy it must be less than 1,440,000 bytes (1.44 MB). If it is larger than thisyou cannot use the floppy approach.Note backup filename that you want to copy from the /tmp/backup to the floppy. Then:Mount the floppy as described in Section A.5.1.Copy the file to the floppy using the cp command:# cp /tmp/backup/<filename> /mnt/floppy where the filename corresponds to the backup file that you want to copy.Verify that the file was properly copied by typing:$ cd /mnt/floppy$ ls –alsUn-mount the floppy as root with the commands:# cd /# umount /dev/fd0Copy to a CDROM For large backup files that exceed 1.44 MB, then you can use the CDRW to write a CDROM.To do this cd to the root of the directory you want to make into a cdrom. Using the example ofbackups stored in /tmp/backup, as operator type,# cd /tmp/backup# mkisofs –v –V ”RVP8 SETUP” –o /tmp/rvp8.iso /tmp/backupWhere the volume label is arbitrary text specified in the quotes (e.g., ”RVP8 SETUP”), file/tmp/rvp8.iso is the the temporary iso image file you are building. You can call this anything. Toactually burn the cdrom, place a blank write-once or re–writeable disk into the CDRW and thentype:# cdrecord –v speed=8 dev=0,0,0 –eject /tmp/rvp8.iso(Note the comma delimiters in 0,0,0)The specific options might be a bit different based on hardware. For example the max speed, orthe device if there are more than one scsi devices. You can type ”cdrecord –scanbus”to see all the scsi devices. If the CDROM drive is not in the list then you cannot use thisprocedure. However, for a standard SIGMET installation it will show in the list.
Software InstallationRVP8 User’s ManualApril 2003A–24A.6 Software Upgrade and SupportA.6.1 Where to get software upgradesThe RVP8 and RCP8 (collectively the RDA) are active products. New features and bug repairsare provided in the form of software upgrades. Software upgrades from SIGMET can beobtained from two sources:RDA Network Upgrades- These are available from ftp.sigmet.com. Forexample, to obtain the release RDA 8.00 you would go to: ftp.sigmet.com/outgoing/releases/rda–8.00Section A.6.4 shows a typical ftp session. These public releases are FREE ofcharge but do not include support services unless you are under warranty or havepurchased a support contract from SIGMET. Contact support@sigmet.com if youneed to arrange a support contract.CDROM Upgrades- these are provided as part of a support contract and containmanuals and source code as well as the operational software.A.6.2 When should I upgradeIf your system is working fine and you do not require the new features of a release, then oftenthe best thing is to NOT upgrade. Check the release notes available at www.sigmet.com in thecustomer support section to see what changes have been made since your current release wasinstalled. Be sure to check the release notes for all intervening releases.To check the release that you have currently installed, you can type the command:$ show_machine_code –versionIRIS Version 8.00 (indicates version 8.00)A.6.3 How should I upgradeThere are two basic upgrade techniques:CDROM Full Re-Install- Backup your configuration files and network files andthen do an install from scratch as described in Section A.3.3. This is not thepreferred technique since it is possible that the backup of configuration files willbe incomplete.Upgrade using “install” utility- This is the preferred technique since it leaves allconfiguration files intact. This is described in Section A.6.5.Once you have decided on either a network or CDROM upgrade, then proceed with the upgradeinstallation as described in the sections below.
Software InstallationRVP8 User’s ManualApril 2003A–25A.6.4 Getting the network upgrade filesThere are two ways to get the network upgrade files. Both techniques use ftp to get the filesfrom ftp.sigmet.com. The ftp client service is enabled on the RVP8 allowing you to run an ftpsession on the RVP8 and “get” files from another networked computer:Use the RVP8 to get the files- a one-step procedure that requires that you haveinternet access from the RVP8.Use another machine on the network– a two-step procedure to first ftp the filesfrom SIGMET to another computer, and then “get” them from this machine byrunning ftp on RVP8. Note that an alternative is to copy the files to a CDROMand then mount the CDROM on the RVP8 and copy the files.No matter what technique you use, you will need some basic familiarity with ftp. Here we willassume that the RVP8 has direct internet access (the one-step procedure). The two-stepprocedure is analogous.Important: The default security configuration allows the ftp client to run locallyon the RVP8, but does not allow ftp access from other systems to the RVP8.Therefore, you must always run ftp from the RVP8 to “get” the files there.The one-step approach: Direct download to RVP8On the RVP8, create a directory called /tmp/rda–X.XX. Here the X.XX is theversion number of the RDA software that you want to install. This namingconvention makes it easy to identify the version of the install files. As operatortype (assuming version 8.00 for all examples here):$ cd /$ mkdir /tmp/rda–8.00Position yourself in the /temp directory by typing:$ cd /tmp/rda–8.00Note that on a windows machine, all of the commands below can be typed in the MS–DOSprompt window (remember to use the “\” backslash for DOS).Start ftp and follow the sample session below (your responses are indicated bybold)$ ftp ftp.sigmet.comConnected to ftp.sigmet.com220 Welcome to SIGMETName: anonymous331 Guest login ok, send your complete e–mail address as password.Password: <Use your email address>230 Guest login ok, access restrictions apply.ftp> cd outgoing/releases/
Software InstallationRVP8 User’s ManualApril 2003A–26ftp> dirYou will see a directory listing of available releases. You are looking for an “rda”release. Assume it is rda–8.00, then:ftp> cd rda–8.00ftp> dirNow you will see a list of files with file sizes. If you have a low-speed link, thenyou will want to download only a minimal installation which consists of:app.gzinstallinstall.gzinstall.rfinstirisMake a list of the files that you want to download including at least the five filesin the list above, and then prepare to download by selecting BINARY filetransfer:ftp> bin200 Type set to I.Important: If you do not specify BINARY transfer, the download will not work.Now “get” the files, for example:ftp> get app.z200 PORT command successful.150 Opening BINARY mode data connection for app.gz (4897560 bytes)226 Transfer complete.You will get a confirmation that BINARY transfer is being used and the size ofthe file in bytes is displayed. Depending on the size of the file and the speed ofyour connection, the download could take many minutes. When the file transfer iscompleted, you will get a confirmation message.You can also use the multiple get command “mget” to get all of the files:ftp> mget *You will be prompted for each file download so you can still pick- and-choose bytyping “y” or “n” to select (yes or no).After you have downloaded all of the files, then end your session by typing:ftp> quit221 Goodbye$ (back to UNIX prompt)For the one-step approach, you have all of the files that you need in the directory /tmp/rda–8.00on the RVP8.
Software InstallationRVP8 User’s ManualApril 2003A–27Completing the two-step approach using another computerThe two step approach is to use another computer to get the upgrade files and then get these fileson the RVP8. The first step of getting the files from SIGMET is done analogus to the one-stepapproach described above. The second step is to ftp the files from the other computer to theRVP8. This is also analogous to the procedure described above. An alternative is to put the fileson a CDROM, mount the CDROM on the RVP8 and then copy the files to the RVP8.The end result of all these various procedures is that the upgrade files are on the RVP8 in adirectory called /tmp/rda–X.XX. NSet the modes on the filesBecome root using the su command and password. Go to the RVP8 directory where the fileswere downloaded and change the mode on two of the files that require execute privilege, i.e.,# cd /tmp/rda–8.00# chmod +x install# chmod +x instirisYou are now ready to move on to the next section.Alternative download technique using a browserAn alternative, but somewhat less reliable approach to using the manual ftp commands is to usea browser such as Netscape. To connect to the SIGMET ftp site, simply type–in the address ftp://ftp.sigmet.comYou can then click on outgoing/releases/rda–XX.X to get a list of files to download. Whileholding the “Shift” key, click the file that you want to download. You will be prompted to selecta destination directory and file name:Warning: Use this technique with caution only if you are sure that you knowhow your browser is functioning. Each browser is different. Some mayperformASCII rather than BINARY transfers. Also, some may re-name the fileswhen they are copied. If this is the case, then be sure to re-name them back tothe original name, with lower-case letters.
Software InstallationRVP8 User’s ManualApril 2003A–28A.6.5 Starting the “install” utilityThe install utility is a graphical user interface that allows you to install SIGMET-suppliedsoftware either as a new installation or as an upgrade. In the case of the RDA, install is used toperform software upgrades only. New RDA installations use the procedure described in SectionA.3.3 since this also conveniently installs the proper Linux operating system in one step.install can be used to upgrade from either of two sources:From a release CDROM provided by SIGMET.From files placed in a local directory (e.g., /tmp/rda–X.XX). These files areobtained via an ftp download as described in the previous sections.Login as operator to start X–WindowsInstall uses X–Windows, so must be run from an X–terminal rather than the full scree textdisplay. Login initially as operator to start X–Windows. Start a terminal and become root byissuing the “su” command and password (default is 8x’s- xxxxxxxx).Stop all SIGMET applications and processesBefore you can actually do the upgrade, you must make certain that all SIGMET applications arestopped. You can do this by exiting any utilities and then typing (as root) “killall rvp8” (orrcp8). Then type ps_iris to verify that all SIGMET processes are stopped. If there are remainingprocesses, you can stop them as root with the “kill <process ID number>” command. Theprocess ID number is the first column of numbers displayed in the ps_iris result.Running “install” from a SIGMET RDA release CDROM If you have a SIGMET release CDROM, install can be run directly from it. First either login asroot or become root using the “su” command. Then mount the CDROM:$ supassword:# mount /dev/scd0 /mnt/cdromOR if this does not work because of the specifics of your hardware type:# mount /dev/hdb /mnt/cdromAfter you have successfully mounted the CDROM, run install as follows:# cd /mnt/cdrom/linux# ./installWhen you have finished running install, you need to unmount the CDROM and eject it:# cd /# eject /mnt/cdromRunning “install” from a local directoryThe procedure is identical to the CDROM procedure described above, except you invoke installin the local directory (e.g., first “cd /tmp/rda–8.00”).
Software InstallationRVP8 User’s ManualApril 2003A–29A.6.6 Using the install utilityThe install utility is shown below. The utility allows you to select the source for the files and thesystem on which you want to do the installation. You can also select which files you want toinstall. The menu fields are described in the following sections.rvp8rvp8Install from/to, Read from- select whether you are installing from a temporary directory or aCDROM. Type-in the directory that contains your install files. In the example, this is/tmp/rda–8.00Install from/to, Install to- Type-in the network node name of your RVP8 or RCP8. If you areunsure, look at the very top of the menu. In the example, the nodename is rvp8. Enter thedirectory anchor point for the install– typically this is /usr/sigmet (the factory default).What to install- click the Upgrade button and any special packages that you may want toinstall. In the case of an installation from a local directory, be sure that you have downloaded thecorresponding files from SIGMET. For a minimal installation you would select only theUpgrade option. If you are installing from CDROM then you have the manuals there so alsoselect Manuals to get the most up to date documentation.
Software InstallationRVP8 User’s ManualApril 2003A–30Keep old files- should be clicked-in, unless the release notes specify otherwise.When you have finished making your selections, then click Start to do the install. A text statusscreen will show you the progress of the install. If you had clicked Verbose, then this statusscreen would show more detail.install error message that applications are still runningThe most common problem in running install is that SIGMET application processes are stillrunning on the system. You will get a message complaining that there are processes still running.Perhaps you forgot to do a “killall rvp8” or have other utilities running. Check Section A.6.5for instructions on stopping SIGMET processes.After all processes are stopped (a clean ps_iris), then click Start again.
Software InstallationRVP8 User’s ManualApril 2003A–31A.7 Network BasicsThe RVP8 and RCP8 are generally delivered from SIGMET packaged as fully integrated Linuxbased computers running the SIGMET RDA application software. Being Linux computers, theyhave the ability to interface to a computer network- in fact, for normal operation incommunicating with host software running on a different computer, they must be connected to anetwork. This chapter gives some helpful information for:The default RVP8 or RCP8 configuration as deliveredHow to change this default configurationHow to use the RVP8 and RCP8 in conjunction with other hosts on the networkA.7.1 Default Out Of The Box Configuration When delivered as fully integrated Linux computers, the RVP8/RCP8 has two LAN interfaces.These are designated as ETH0 and ETH1. The ETH0 interface is the only one that is enabled bydefault. The ETH1 interface is available, but no enabled. Both of the LAN interfaces are RJ–45style ports that accept a standard LAN twisted pair style cable. SIGMET recommends that CAT5e or better cable be used for this connection.On most systems there are two network connectors. Usually ETH0 isthe left one (looking at the back of the unit) next to the VGA connector.Depending on the version of the motherboard, the LAN interfaces are both either 10/100 Mbps,or 100/1000 Mbps. In both cases the interfaces will negociate to the highest speed allowed bythe device (often a hub or a switch) that they are connected to. To determine the style ofmotherboard, look at the Model Number in the back corner of the motherboard. If it has a –Qsuffix, the LAN speeds are 10/100. If it has a –G2 suffix, the LAN speeds are 100/1000.The IP address of the RVP8/RCP8 out of the box is 192.168.76.90 with subnet mask of255.255.255.0. There is no default route nor DNS server configured. Thus the RVP8/RCP8could be used immediately on network identified as 192.168.76.0.The RVP8/RCP8 is configured with only a minimum number of network services running. Thisimplies a very conservative (safe) network security profile. The only service that is running isthe portmapper as this service is required by the SIGMET RDA application software. With avery safe and conservative security policy such as this out of the box configuration, the RVP8and RCP8 will be able to exist on the network and have no security concerns.
Software InstallationRVP8 User’s ManualApril 2003A–32A.7.2 Making Changes to Default ConfigurationThe one change that probably will be needed to the RVP8/RCP8 in almost every instance is tochange the default IP address of ETH0. This will of course allow you to use the RVP8/RCP8 ona pre–existing computer network.IP Address ConfigurationTo change the IP address, you must edit the file /etc/sysconfig/network_scripts/ifcfg–eth0. Thedefault version of this file will have about 10 lines and two of them of the format:IPADDR=192.168.76.90NETMASK=255.255.255.0You may change the IPADDR to any valid address and if necessary, you should also change theNETMASK. You should contact your network administrator for assistance in identifyingappropriate values for these lines. The other lines in the file require no change. It should benoted that the RVP8/RCP8 requires the same IP address all the time, thus dynamic IP addressing(such as DHCP) is not appropriate. After making the above changes to the ifcfg–eth0 file, youshould reboot to make the changes take effect.If you wish to use the second LAN interface (ETH1), to configure this, you should create the fileifcfg–eth1 in the /etc/sysconfig/network–scripts directory. The easiest say to do this is to justcopy the ifcfg–eth0 file to ifcfg–eth1. Then edit the ifcfg–eth1 file and change the“DEVICE=eth0” line to read “DEVICE=eth1”, and change the IPADDR and NETMASKlines as appropriate. Again, contact your network administrator for assistance in identifying theappropriate values. In addition, you must edit the file /etc/modules.conf and for –Q seriesmotherboards, add to the end a line reading “alias eth1 eepro100”. For –G2 seriesmotherboards, add a line reading “alias eth1 e1000”. Then reboot to make these changestake effect.Default Routes and HostnameIn the default configuration, the RVP8/RCP8 can communicate with any other computer on thelocal network, but is not configured to communicate with computers on other networks.To allow such communication, edit the file /etc/sysconfig/network and add the line“GATEWAY=192.168.76.1”. Of course substitute the IP address of your default gateway for the192.168.76.1 value in this example. You system administrator can provide you with the correctvalue.Also in the same file a line such as “HOSTNAME= localhost.localdomain” exists in thisfile. You can substitute a new hostname for the “localhost.localdomain”. You mustalso edit the file /etc/hosts and add to this a line that first lists the IP address of your ETH0, thenlists your hostname exactly as it appears in the /etc/sysconfig/network file.After making any changes to default routes and/or hostnames, you must reboot your computerbefore they will take effect.
Software InstallationRVP8 User’s ManualApril 2003A–33Hosts and DNSIn the out of the box configuration, the RVP8/RCP8 can communicate with other computers onthe network, but only by using IP Addresses. If you want to communicate with other computersusing Hostnames, you must configure either a hosts table or DNS. Generally, a small network ofonly a few computers uses a hosts table, while large networks generally use DNS. It is up to youto decide which method is appropriate and again, your network administrator can provideadvice.To configure hostnames using a host table, this is done by editing the /etc/hosts files and addinglines that default the IP address of a host and its hostname. For example, a line such as:met_serverwould allow you to communicate with the host “met_server” using its hostname rather than itsIP address.For DNS, you do not need to enter individual hostnames into a local host file, but it is assumedthat all of the hostnames and IP addresses are stored on a central DNS server. All you need to dois to install a pointer to this server computer and then you can communicate using hostnames toany of the computers in the list on the DNS server. To enable DNS, edit the file /etc/resolv.confand add a line such as:nameserver 192.168.76.99Of course substitute the IP address of your DNS server for the “192.168.76.99” listed above,and again, your network administrator can provide you with the appropriate information.Time Zones ConfigurationBy default, the system clock and time zone of your RVP8/RCP8 are set to UTC (Universal Time– also called Greenwich time). If you wish to change your time to be reported as local timerather than UTC, you can use the “timeconfig” utility to do this. When using timeconfig, youneed to select your local time zone from the list provided. And also you need to select if theBIOS stores time in UTC. SIGMET recommends using BIOS time in UTC because this is morestandard. But you are free to choose any timezone (or UTC) from the list provided. You shouldreboot your computer after making any change using “timeconfig”.Time Synchronization using NTPBecause the data generated by the RVP8/RCP8 is time stamped, it is often useful to have anautomated way of keeping the system clock accurate. Using the Network Time Protocol (NTP)is an effective and easy way of doing this.To use NTP, you must have an NTP server on your network. Often this is a single system whereyour network administrator oversees keeping the clock accurate so other computers can synctheir clocks to it. There are also automatic NTP servers that sync their clock to GPS (satellitebased time) and then other computers can sync to this.Assuming you have such an NTP server available on your network, to setup NTP on theRVP8/RCP8, you must first execute the command “chkconfig –service ntp on”. Nextyou must edit the file /etc/ntp.conf and find add the line “server 192.168.76.98”. Of
Software InstallationRVP8 User’s ManualApril 2003A–34course substitute the IP address of your NTP server for 192.168.76.98 in this example. Thereare many other lines in the /etc/ntp.conf file, but these are not used for normal configuration andmust be left with a comment symbol “#” prefixing them. Generally, you should only have oneline without a comment symbol, and that is the “server ...” line defined above. Next youshould edit “or create” the file /etc/ntp/step–tickers. In this file put only the IP address of yourNTP server. There should be nothing before or after the IP address, and it should be the onlyline in the file. The /etc/ntp/step–tickers file causes your computer to sync its time abruptly tothe NTP servers time while your computer is booting, and the /etc/ntp.conf file causes yourcomputer to periodically compare its time to the NTP server and make small adjustments asneeded. Once again, you must reboot your computer before the above changes take effect.Adding Network ServicesIf more network services are required (such as telnet, rlogin, ftp, ...) these can be optionallyenabled. Before enabling such network services, it is advisable to review these decisions withyour network administrator to make sure that the network safety of the RVP8/RCP8 is notcompromised. The easiest way to enable these services is by using the “ntsysv” utility. Whenrunning this utility, you are presented with a list of many system services (not only networkservices). Services that are currently enabled have a star “*” in front of them. You can eitherenable or disable a service by scrolling to it and then pressing the space bar. This will toggle thestar and thus if the service is enabled.Again, it is recommended that you discuss with your system administrator before making anychanges because such changes could have a profound effect on the security of your system.After making any changes, you should reboot your computer before they will take effect.One such services that you might want to consider enabling is telnet. Telnet allows your to loginto your RVP8/RCP8 from another computer on the network and is often convenient. Telnet usesa user name and password for security authentication.
PackagingRVP8 User’s ManualApril 2003B–1B. RVP8/RCP8 PackagingA standard RVP8/RCP8 processor consists of three separate units:Main Chassis Section B.1 RVP8 and RCP8Connector Panel Section B.2 RVP8 and RCP8IFD (IF Digitizer) Section B.3 RVP8 OnlyBecause of the similarity of the packaging for the RVP8 and RCP8, both units are describedhere.The main chassis and connector panel are located in a rack within 100m of the IFD. Typicallythe main chassis interfaces to a host computer via 100 BaseT Ethernet. For the RVP8, the IFDreceiver module resides in the radar cabinet.This section describes the general features of the packaging and the electrical specifications andcabling of these units. Please read CAREFULLY the following warnings before you applypower to your system.WARNING: The Main Chassis power supply modules are NOT auto ranging. These mustbe set by a switch on each module for either 115/230 VAC 60/50 Hz. Verify these beforeapplying power to the system. See Section B.1.3.WARNING: Turn off power to the main chassis before installing or removing any PCIboards. For safety, the line cord should be disconnected before opening either the IFDmodule or main chassis.Important: The circuit boards contain many static sensitive components. Do not handlethe boards or open the IFD module unless a properly grounded wrist strap is worn.
PackagingRVP8 User’s ManualApril 2003B–2B.1 Main Chassis General DescriptionSIGMET’s standard main chassis is a 4U rackmount/table top enclosure (43.2 wide x 43.2 longx 17.8 cm high) or (17 wide x 17 long x 7.00 inch high) which fits a standard 19-inch EIArack. The system comes standard with hot–swap redundant power supplies. The chassis may beequipped with either a mother board or a single-board computer depending on how the unit waspurchased. The chassis is shown in the following figures.Front View Figure B–1Rear View Figure B–2Side view Figure B–3Internal Wiring Figure B–4The front of the unit has a plasma matrix display that is used for status information. There is alsoa CDRW drive (for software installation and backup) and in most cases, a floppy drive as well(for configuration backup).Two fans are mounted behind the door on the front of the enclosure. These draw ambient air into the unit. The air flows through the unit and exits the rear. Do not block the slots or the exhaustgrills on the fans. Check airflow now and then, and also check the board and fan screen for dustaccumulation. If necessary, excessive dust accumulations on the board can be cleaned at aproperly equipped static-free workstation with “canned air” or Chemtronics TF-Plus solvent,which can be purchased through electronics distributors.The boards should be left in the chassis whenever the unit is shipped. This minimizes handlingand static risk.

PackagingRVP8 User’s ManualApril 2003B–7B.1.1 Main Chassis Front PanelThe front panel is shown in Figure B–1. The front panel matrix plasma display is typicallyconnected internally by a ribbon cable to either an I/O-62 card or an RVP8/Rx card. The displayis used to show status and power-up test results. Power–up features are described in detail inSection 2.3.5. The function keys beside the display are not currently used.RVP8 Receiver/Signal ProcessorRCP8 Radar Control ProcessorIn addition, the CDRW and the floppy drive are located on the front panel. The various activitylights are for the CDRW (yellow), floppy drive (small green) and the hard disk drive (large red).The cabling diagram shows how to connect the activity lights. At the lower right of the unit is apower on/off switch and a green LED to indicate that power is on.
PackagingRVP8 User’s ManualApril 2003B–8B.1.2 Main Chassis Back Panel Figure B–2 shows an example of the main chassis back panel for the case of a motherboardsystem. There are three main sections to the Main Chassis back panel:Power section- on the left (looking from the rear) with the power entry module,alarm reset and three redundant hot-swap power supplies.PC I/O section- in the lower center with connectors for keyboard, mouse,monitor, network, etc. This is for a mother board example.PCI card section- on the right (looking from the rear) with standard PCI slots forthe RVP8/RCP8 circuit cards as well as other standard commercial PCI cards thatmay be used (e.g., a four port serial card).Note that depending on whether your system is using a mother board or single-board computer(SBC), the appearance of these sections may be different, but the functions are the same. Thesesections are described in detail in the sections below.
PackagingRVP8 User’s ManualApril 2003B–9B.1.3 Main Chassis Back Panel Power SectionWARNING: The Main Chassis power supply modules are NOT auto ranging. These mustbe set by a switch on each module for either 115/230 VAC 60/50 Hz. Verify these per theprocedure below, before applying power to the system.The Main Chassis back panel is equipped with a modular AC power entry device. There arethree hot-swap redundant power supply modules in the system. The procedure forsetting/verifying the voltage on each one is as follows:The unit should be powered-off. This can be assured by simply not connecting thepower input cord.Remove the top power supply module by shifting the black release button to theright.Use the handle to pull the module out.Check the red power selector switch on the right side (rear) of the module and setit as appropriate to your line voltage (115/230).Re–insert the module and push the chrome handle down. This switches themodule in the on “1” position.Repeat this procedure for the middle and lower modules (the order is notcritical)).When the system is switched–on, the LED on each module shows green to indicate that it isfunctioning properly. A red light indicates a failure. There is an audio “buzzer” alarm in theevent that a power module is turned-off, removed or fails.Note: The red button next to the power entry module will reset the “buzzer” alarm.The system will function if there is failure of any one power module, but is not rated to functionwith only one module, i.e., if two modules fail. Each power module is equipped with internalprotection for over-temperature and over-current. In the event that the protection is triggered, themodule LED will show red. It can be reset by removing the module for a minute and theninserting the module back into the system. It is best to do this with power–off to the module.Note: If a power module is switched on, but the LED indicator is red, then it is notfunctioning. The reset procedure is to turn the power off on the failed module, remove itfor one minute and then re-insert it and power it back on.

Notepins (male) are indicated by filled black circles while sockets (female) are indicated by opencircles.A standard keyboard and mouse are provided with the unit. VGA monitor is supplied by thecustomer or ordered as an option from SIGMET.Note that LAN 1 and LAN 2 are standard RJ45 connectors. For the –G2 style mother boards theLAN port speed is 100/1000 BaseT. For the –Q they are 10/100 BaseT.The keyboard and mouse are standard PS/2. You can use an adapter to plug a USB mouse intothe circular mouse connector.COM1 is the DBM9 connector. COM2 is typically installed as a separate DBM9 connector in thePCI section.
PackagingRVP8 User’s ManualApril 2003B–11B.1.5 Main Chassis Back Panel PCI Card SectionThe PCI cards are installed vertically on the right of the chassis(looking from the back). Since there are many differentRVP8/RCP8 configuration options that can be ordered, there isquite a bit of variability in what PCI cards are installed. For theRCP8, however, there is typically only an I/O-62 PCI Card.Note that COM2 is typically installed as a connector in the PCIsection.PCICard Used on Vendor FunctionsI/O –62 RVP8 RCP8 SIGMET I/O to radar system control and monitoringRVP8/Rx RVP8 only SIGMET Uplink/Downlink IFD connections.

The I/O-62 is used on both the RVP8 and RCP8. It is described in the nextsections, along with the standard connector panels for the RVP8 and RCP8.
PackagingRVP8 User’s ManualApril 2003B–12B.2 I/O-62 and Connector Panel Figures B–5 and B–6 show the I/0-62 Connector Panel for the RVP8 and RCP8. This istypically mounted on the same rack as the Main Chassis. A 1:1 62–position cable (standard 1.8m/6 foot) connects the connector panel to the I/O-62. As shown in the figures, the cable can beconnected to either the front or the back of the panel so that the cable run can be optimized. Inmost cases, it is recommended to connect the cable to the back of the panel to minimize the riskof physical damage to the cable.The panel is electrically the same for both the RVP8 and RCP8.Indeed the circuit board isidentical. However, the panel labelling and the softplane configurations are different.The pin assignments to the various connectors are described in Tables B–1 to B–14 located atthe end of this section. The tables show the basic electrical properties of each pin and the defaultsignal assignment (if any) that is made in the factory softplane.conf file. The softplane approachprovides a great deal of flexibility in assigning the I/O to the panel.The I/O–62 PCI card provides forty multi–protocol digital interface lines at its 62–pin faceplateconnector. These lines are grouped into five independent and identical blocks, each of whichcontains eight lines. Moreover, each of these blocks of eight lines can be further divided intofour line pairs.Each block of I/O lines can operate in one of the following modes:As eight TTL/CMOS single–ended outputsAs eight TTL/CMOS single–ended inputsAs N RS–422 differential transmitters or receivers, and (8–2N) TTL/CMOSsingle–ended inputs.The assignment of electrical levels and signal directions are all made in the ’softplane.conf’ file.Users do not have to worry about how to configure each block of lines because inconsistentsignal assignments will be checked and reported when the file is loaded.All forty I/O–62 digital lines are individually protected against both overvoltage and electrostaticdischarge (ESD). You may safely apply voltages between –27V and +27V to any line regardlessof whether it is configured for an input or output. Likewise, external ESD pulses of 15KV(Human body model) will be safely shunted to ground at the 62–pin connector point of entry.This wide voltage tolerance effectively makes the TTL/CMOS inputs function as wide rangecomparators with a 2.5V logic threshold. These inputs could be connected directly to a 24Vpanel bulb, for example, in order to monitor its On/Off status. Note that the line protectioncircuitry has a side effect of raising the output impedance of the TTL/CMOS drivers toapproximately 120–Ohms. This should not cause any trouble unless the signal is heavilyterminated at the receiving end. The RS–422 drivers are not affected by the line protection, andhave the standard very low output impedance.The I/O–62 provides a variety of terminations for its digital I/O lines. The TTL/CMOS signalscan optionally be pulled either to GND or to +5V through a 2.2K–Ohm resistor. Similarly, theRS–422 linepairs can optionally be terminated with a 100–Ohm resistor across each pair.
PackagingRVP8 User’s ManualApril 2003B–13There are a few additional constraints that should be kept in mind when assigning electricalsignals to a block of eight I/O–62 lines. These are:When TTL/CMOS pull-up/pull-down resistors are enabled, they are applied tothe entire group of eight lines. This is somewhat inconsistent with using some ofthose same lines as RS–422.Similarly, when RS–422 terminators are enabled, they are applied to all four linepairs. This is completely inconsistent with using some of those same lines asTTL/CMOS.Thus, if line termination is required, it is usually necessary to split the TTL/CMOS and RS–422functions so that both do not appear within the same block of eight lines.

PackagingRVP8 User’s ManualApril 2003B–28B.3 IFD Module (RVP8 Only) The IFD module is a small metal box which can be mounted inside the receiver cabinet. TheIFD is shown in Figures B–7 and B–8. Cooling of the inside components is accomplished bydirect conduction to the case. It is desirable to place the module in an environment that allowsexternal convective cooling.The IFD is equipped with its own auto ranging power supply (110 to 240 VAC 50/60 Hz) whichis mounted on the side of the IFD. On the other side of the IFD are two anti-aliasing filters.These analog filters must be specified for the radar IF frequency. The filters have an 8 MHzbandwidth centered about the IF frequency.

PackagingRVP8 User’s ManualApril 2003B–31B.4 DAFC Module (RVP8 only) The Digital AFC (DAFC) module is used on RVP8 for magnetron systems to interface to adigitally controlled STALO. The DAFC “T’s” off the coax uplink cable. Power can be providedby running discrete wires from the IFD. Note that +5 VDC is all that is required to run theDAFC. If you want to supply the STALO power over the ribbon cable to the IFD, you canconnect the +24 VDC input to an appropriate power supply. Otherwise, you can power theSTALO directly.The DAFC outputs up to 24 TTL lines to the STALO digital control/interface. Since these areTTL, the DAFC should be mounted within 10 to 30cm of the STALO if possible. For details onthe DAFC, including pin assignment examples for some commercial STALO’s, please refer toSection 2.4.Figure B–9: View of DAFC Module
Clutter Filter CharacteristicsRVP8 User’s ManualApril 2003C–1C. Clutter Filter Characteristics (DRAFT)This draft appendix is based on the legacy RVP7 algorithms. The RVP8 will have someadditional features and may not contain some of the legacy features.The RVP8 is shipped with a preprogrammed set of digital IIR (Infinite Impulse Response)high-pass clutter filters. There are eight filters available. The filters are fourth-order Chebyshev,and provide 40dB and 50dB stop band attenuation in seven different widths ranging fromapproximately 2% to 14% of the Nyquist interval. Filter #0 is an all-pass filter, so that clutterrejection can effectively be switched off.The correct choice of filter for observing different weather conditions must be determined byexperiment. The filter with the highest rejection is not always the best choice, since the groupdelay of signals in the transition band is greater for deeper filters. This effect introducesdispersion in the Velocity/Time profile of the incoming signal. In general, try to use theshallowest filter with the shortest impulse response that will do the job for the types of weatherand clutter that are typical at the radar site.The processing algorithm for the IIR clutter filter is described in Chapter 5, as follows:AnB0AnB1An1B2An2B3An3B4An4 C1An1C2An2C3An3C4An4In this algorithm, the input time series An is processed to form a filtered output time series An,and the B’s and C’s are filter coefficients.

Because the tests also function asan installation procedure, they must be completed in order. Failure to perform one step mayeffect later tests.A copy of the test results should be kept either on file or with the RVP8 User’s Manual. Do notwrite in the manual since it will be replaced with an upgrade, instead make a copy and mark that.For IRIS systems, it is recommended that the RVP8 TTY nonvolatile setups be put into a file onyour system in the ${IRIS_LISTINGS} directory. The file should be called something likeRVP8.26feb2000. The UNIX script command can be used to to create this fileEach test should be performed and signed off when it is completed. If a test does not pass, thenthe problem should be remedied and the test repeated. If the test still does not pass, then anadditional sheet should be added to the test explaining the variance. A supplementary test sheetis at the end of the test procedure.After you have successfully completed the installation steps and tests in this procedure, yourRVP8 will be ready for connection to your application software such as SIGMET’s IRIS system.There will be additional configuration and calibration to use the RVP8 with your applicationsoftware.The following page is a convenient summary check list for the tests.

Installation and Test ProcedureRVP8 User’s ManualApril 2003E–10E.8 Setup “Mt” Command (General Trigger Setup)Test GoalVerify that the TTY setups for the General Trigger Setup section are properly configured for thecustomer application.BackgroundThe RVP8 can output up to 6 different triggers. These can be delayed by different amounts, andhave different pulse widths. For example trigger 0 may go to fire the transmitter, while aslightly delayed trigger 1 may be used for triggering an oscilloscope. The timing can bedifferent for each transmitter pulsewidth. The final timing adjustments will be done later inSection E.14. Enter in the table below the purpose of each trigger, as well as the nominal starttime and pulse width. Note that start times are relative to range zero (middle of the burst pulse).We recommend a nominal pulsewidth of 3 microseconds. This chart will be used in the nextsection.Magnetron radars using an analog COHO system often have a trigger generator circuit whichproduces a trigger for the COHO latching and also for the transmitter pulse. This circuit shouldbe bypassed in an upgrade.# Purpose Start Time Width0 ________________________________ ________usec ________usec1 ________________________________ ________usec ________usec2 ________________________________ ________usec ________usec3 ________________________________ ________usec ________usec4 ________________________________ ________usec ________usec5 ________________________________ ________usec ________usecSpecial Test Equipment: Setup TerminalReference: RVP8 User’s Manual, Section 3.3.4Test ProcedureEnter the TTY setups and type the “Mt” command.

Installation and Test ProcedureRVP8 User’s ManualApril 2003E–11E.9 Initial Setup of Information for Each Pulse WidthTest GoalEnter the initial values for the TTY Setups for each of the pulse widths. Note that the finalvalues of trigger timing, FIR filter impulse response length and bandwidth will be adjusted later.BackgroundThe duty cycle of the transmitter is the product of the PRF and the pulse width in seconds. Forexample, a PRF of 1000 Hz and 1 microsecond pulse width is a duty cycle of 0.001. Thus atransmitter with a 0.001 duty cycle limit could function at 1000 Hz and 1 microsecond pulsewidth, or 500 Hz and 2 microsecond pulse widths.The duty cycle limits of your radar should be obtained from your system documentation or radarmanufacturer. The RVP8 supports up to four pulse widths (coded 0 to 3), although mosttransmitters typically support only two pulse widths. Record below the pulse width inmicroseconds and the maximum PRF that is allowed for each pulse width.# Pulse Width Max PRF0 __________ microseconds ________ Hz1 __________ microseconds ________ Hz2 __________ microseconds ________ Hz3 __________ microseconds ________ HzSpecial Test Equipment: Setup TerminalReference: RVP8 User’s Manual, Section 3.3.5Test ProcedureEnter the TTY setups and type the “Mt #” command, once for each pulsewidth.

Installation and Test ProcedureRVP8 User’s ManualApril 2003E–12E.10 Setup “Mb” Command (Burst Pulse and AFC)Test GoalVerify that the TTY setups for the Burst Pulse and AFC Configuration section are properlyconfigured for the customer application.Background: Magnetron vs Klystron SystemsMagnetron Systems: For magnetron systems, the phase and frequency of the burst pulse fromthe transmitter is measured at IF. The phase measurement is used for digital phase locking and2nd trip echo filtering and recovery. The frequency measurement is used to implement an analog(+–10V) AFC output to control the STALO frequency. Note that an external AFC can be usedrather than the RVP8 AFC, but is not recommended.Klystron or TWT–based Systems: The COHO is measured instead of the burst pulse. Note thatKlystron systems that use a phase shifter should input the phase shifted COHO into the IFD sothat the RVP8 can digitally lock to the actual transmitted phase. For Klystron systems the AFCfeedback loop is not used.Special Test Equipment: Setup TerminalReference: RVP8 User’s Manual, Section 3.3.6Test ProcedureEnter the TTY setups and type the “Mb” command.

Use the L/R commands to findthe burst pulse. Use the l/r commands to fine tune the position of the burst pulse in theburst pulse window. Adjust the width of the burst pulse window using the I/i command to be slightly largerthan the burst pulse (e.g., ~50%).Verify that the burst pulse power is in the range +1 to –12 dBm per the tabular displayon the setup terminal.Record the burst pulse powerPulsewidth #0: _____________ dBmPulsewidth #1: _____________ dBmPulsewidth #2: _____________ dBmPulsewidth #3: _____________ dBmRepeat the above procedure for each pulse width.In the event that the burst pulse is not found, try to detect the burst pulse on an oscilloscopeconnected directly to the IF burst line (ahead of the IFD). On a magnetron radar, if the AFC isnot working it is possible the IF frequency is outside the IFD anti-aliasing filter bandwidth. Itmay be necessary to go to manual frequency control to get this to work. If no burst pulse isdetected, then the radar should be serviced by an experienced technician. If the burst pulse ispower is too small or large, check the status of any attenuators or amps in the burst pulse signalpath. It might be necessary to adjust the gain buy installing a fixed attenuator or amplifier.Test PassedFor Customer _____________________________________ Date ____________For SIGMET _____________________________________ Date ____________

This is done be observing the power inthe noise using the Pr command.Reference: RVP8 User’s Manual, Section 4.6Special Test Equipment: Setup Terminal and display scopeTest ProcedureSet the transmitter to radiate and elevate the antenna to >45 degrees to minimize the ef-fects of weather or clutter echoes (including earth noise). Be sure the antenna azimuth ispointed away from the sun or any known RF interference sources you may have.Note: This entire procedure may also be performed with the transmitter offsince, in theory, it is only measuring properties of the receiver. However, youmay notice some noise interaction between the Tx and Rx.Use the setup terminal to enter the Pr command and the display scope to view results.Use the Ll/Rr commands to move out in range to a start range of 50 km so that onlynoise is present.Record the powers displayed on the setup terminal. You can use the V/v command toincrease/decrease averaging of samples to make the noise measurement more stable.Total: _________ dBm, Filtered: _________ dBmNow remove the cable connecting the IF signal into the IFD. Again record the powers: Total: _________ dBm, Filtered: _________ dBmAdd attenuation and/or amplification by an amount such that the Filtered noise power isapproximately 7 dB higher when the signal is connected (See Section 2.2.8).After verifying the above rise in noise level, disconnect the output cable from the LNAand verify that the noise drops to the same level as when the IFD IF-Input was discon-nected. This verifies that the dominant noise is indeed coming from the LNA, and notfrom any of the subsequent IF amplifiers.Test PassedFor Customer _____________________________________ Date ____________For SIGMET _____________________________________ Date ____________

Check the LNA specification to verify themaximum signal that it can accept. The output from the signal generator(accounting for cable and coupler losses) should not be allowed to exceed thisvalue.Reference: RVP8 User’s Manual section 4.6Special Test Equipment:Setup Terminal and display scopeRF signal generatorTest ProcedureRun the radar and test signal generator for 20 minutes to allow proper warm-up of thesystem prior to the test. This will allow the AFC to stabilize.After warm-up is complete, turn the radiate off but leave the receiver on since the testsignal generator may be damaged by the transmitter. The antenna should be elevated to20 degrees and the azimuth should be set to point away from any known microwavesources including the sun.Use the setup terminal to enter the Mt command to set the pulse width to 0.Use the Mt 0 command to temporarily configure the FIR impulse response to 2.89 usec(I/i command) and 0.59 MHz bandwidth (N/n and W/w commands). These settings arefor the purpose of benchmarking the receiver performance. Do not save this result sinceit would override your previously configured band width and impulse response.Connect the test signal generator to inject a signal at RF ahead of the LNA.Enter the Pr mode and make the following settings:Use the space bar to toggle to the power spectrum plot.Use the L/l and R/r commands to set the start to 50 usec.Use the T/t command to set the plot span to 50 usecUse the V/v command to set averaging to 10 samplesSet the signal generator to a value that is approximately 20 dB above noise and observethe scope plot.

This noise does not interfere with the signal tonoise ratio because the bandwidth filter is applied afterwards. The bandwidth of the anti-aliasingfilter should be the limiting factor. This test uses the same hookup as the previous test (SectionE.21). For dual polarization systems, you expect to get a narrower bandwidth.Reference: RVP8 User’s Manual, section 4.6Special Test Equipment: Setup Terminal and display scopeRF signal generatorTest ProcedureConnect the test signal generator to inject a signal at RF ahead of the LNA.Enter the Pr mode and make the following settings:Use the space bar to toggle to the power spectrum plot.Use the L/l and R/r commands to set the start to 50 usec.Use the T/t command to set the plot span to 50 usecUse the V/v command to set averaging to 1 sampleSet the signal generator power to a value that is approximately 60 dB above noise andobserve the scope plot.
