The RI System software can be integrated with a variety of standard network hardware and operating systems. The system controller uses an embedded platform based on eComStation to interface with a RI Guru Server or directly to shared drives and other network resources on the Local Area Network (LAN). The STDF test data is typically transmitted via Guru Agent from the Guru Server via FTP to a central location where the data is accessible to data analysis tool. All required Guru connections are initiated from within the corporate firewall (outbound port 50000 to guru.roos.com), mobile development is possible with virtual workstation that works offline and only needs a temporary VPN connection to transmit updates. The network settings and accounts should be provisioned (planned) prior to the initial shipment of a test system. Please fill out the online survey at least one week prior to the planned ship date.

Connection Diagrams for a typical RI Test System:

Network Configurations

Guru Server (Standard)
  • Backup/Disaster Recovery for Cassini and Virtual Workstations
  • Push "Support Data" via RI Guru Agent connection (TCP 50000) to guru.roos.com for RI
  • Pull "Software Updates" via RI Guru Agent connection (TCP 50000) to guru.roos.com for evaluation
  • Once evaluated, "Push" updates to Guru Server (and all clients)
  • Cassini & Virtual Workstations can freeze software revision with "Short-Cuts"
  • Automated Test Data transfer to "Data Storage" network resource with a Guru Agent.
  • Guru Server is Visualized (runs on customer provided Virtual Machine) for easy provisioning

Guru Server (Enterprise) for multiple sites
  • Everything from "Guru Server" (above), plus...

  • Site to Site exchange handled by Guru Agents
  • Guru Encryption used between all links

  • Guru Server runs as redundant pair on dedicated server class hardware (RI8559A)
Remote Assistance
  • Provides hands on assistance from factory to Cassini or Virtual Workstation
  • Enables real-time evaluation (no email or phone back and forth)
  • "Push" provides password protected reverse VNC connection to vnc.roos.com:5500 (vnc in listening mode)
  • "VPN+VNC" requires a VPN connection from RI and a password protected VNC session
  • Web Conference from any other on-site PC with a VNC connection to the system
    (WebEx, TeamViewer, GoToMeeting, etc)
Exporting Guru Data for Support
  • No direct connection needed
  • Export via "Collect Support Data" action or Guru Browser
  • Import via Guru Importer or Guru Browser
  • eCS must be able to read USB stick (most but not all FAT32 <4GB work)
  • File Server can be SMB, NSF, or FTP
No Guru Server (not recommended) - R&D Environment
  • No test floor internet access required
  • No Backup/Disaster Recovery for Cassini or Virtual Workstations
  • Beta Workstation must have test floor network access to update
  • Does not scale well
  • Cassini can be configured as "Update" and "Backup" Guru
  • Poor Guru performance while testing. DO NOT RUN PRODUCTION VOLUMES!

Typical Network Integration

    From an Test Engineer or Administrative perspective:

      • RI System software uses a "login" to limit operators, developers, and Admin access to required features. Default users are set-up at the factory and they can be easily copied and renamed.
      • For Cassini, the system controller is built-in to the mini-rack with the keyboard, mouse, and touch-screen monitor resting on top. (see Large or Small CASSINI footprint)
        For RI7100A, the customer supplies location for RI System Controller or an optional tray can be attached to the side of the system rack. (see RI7100A footprint)
      • Data distribution can use Guru Agents or a custom FTP script.
      • Testplans can be "released" as read-only to the production systems with specific software revision control (Short-Cuts), preventing accidental alterations on the test floor or unpredictable software related version issues.
      • Software Updates can be easily installed via RI Guru from a network connection (FTP,SMB,or NFS)
        RI7100A systems can also be updated via select USB flash drives (some flash drives are not compatible), CD-ROM, or LS-120 floppy or standard floppy drive.

    From a Production Floor Manager perspective:

      • Customer provided naming convention, typically [CUSTOMER ABBREVIATED NAME] + "A,B,C" or "1,2,3", eases support requests.
      • Handler support (change kit development)
      • A common ground between the tester, test head, fixture, and handler must be maintained to help isolate production issues. A ground wire with alligator clips is provided that connects the RI Systems' ground directly to the handler's ground.
      • For RI7100A systems only, DO NOT connect the RIFL-II cables (with the same RJ45 connections) to LAN or Guru LAN hubs or switches. (see Using the System Controller and RIFL)
      • Site Preparation Guidelines highlight the minimum requirements compared to typical devices on the test floor.

    From a Information Technology perspective:

      • Typical network configuration (Static IP Address or DHCP (preferred) with hostname, Subnet mask, Default Route)
      • Only Guru Server needs inbound access to the internet (below), with the normal LAN is typically used to interconnect Cassini and RI7100A platforms. System Controller or Development Workstation typically used for RI Support, outside internet access greatly simplifies process.
      • Printer type (Postscript): Network printers that support Postscript or LPD (Line Printer Daemon) standard. RI7100A can support direct connections to parallel or USB.
        (See Adding a Network Printer to OS/2 or Streaming Printer LPR Port driver)
      • Custom factory automation tools can interface with network sockets via SEMI Standard E122-0303, Standard for Tester Specific Equipment Model (TSEM)
      • Virtual Workstations run RI System software with virtualization tools like VirtualBox (or VirtualPC)
      • Guru requires outbound TCP port 50000 for Software Updates and remote testplan development, also UDP port 123 for NTP protocol to assure Guru operates at the correct time (UCT).
      • RI-SLP (Guru Server Auto-discovery) requires server to be on same Subnet and "Guru Group"

Ideal Network Environment
An ideal Guru network will use DHCP for the client machines (Cassini Systems and Virtual Machines) with RI-SLP used for Guru Server discovery. This requires the Guru Server to be on the same "subnet" as the System Controllers and Virtual Workstations. This can be easily implemented with VLAN or a dedicated network. This configuration allows a replacement system controller or newly deployed Virtual Workstation to automatically discover the Guru Server and inherit default user login credentials as well as configuration settings.

Network Security
The RI System controller or Guru Server is a typical networked computer and must be protected from the internet like any other critical computer system (i.e. NAT firewalled). The RI System software does have a user account model that is used to limit access to resources and features. RI Guru does not encrypt all data that is transferred between guru systems, so a VPN is required for use over the internet. RI Guru needs outbound access to the internet on TCP Port 50000 to be able to upgrade RI System software or allow test plans to be updated remotely (Guru must be configured for this). The Guru server must also have outbound TCP port 123 for the Cassini testers to get updated time information via the NTP protocol.

Printers - eCS, OS/2 Support
RI systems allow directly attached printers via parallel port (RIFL controller uses the first parallel port), USB, and network (LPD). Drivers are typically supplied by IBM, eCS, or other third parties.
Cassini must use a networked printer accessible from the Guru dedicated LAN.

Typical Data Integration
The RI system software has native support for STDFv4 and ATDF formats. Additional CSV (Comma Separated) or similar formats can be generated with NRE (contact [email protected]). Custom file definitions are typically done with translators after the data has been collected. The data rate and storage requirements are relatively insignificant, with any modern IT infrastructure able to handle everything we can generate (MB per day). Analyzing the data often requires a dedicated STDF analysis tool or spreadsheet application.

Disaster Recovery
If the system controller fails, return it with a RMA to the factory for an exchange. The system controller is configured at the factory and any custom settings would need to be applied by the customer. For this reason, any critical system changes should be documented by the customer and updated when needed. A Guru backup server automatically restores all test plan, calibration, software updates based on the USB dongle that uniquely identifies the system controller.

Exchange RMA Process
All support requests require a valid support contract with active Module Exchange (ME) and/or Hardware Repair Parts (HRP). Contact "[email protected]" to request a RMA (Returned Merchandise Authorization) number and receive specific packaging requirements to prevent damage or documenting instructions so that the equipment can get through customs without delay. Cassini modules are exchanged with a drop-in replacement from the factory (FOB Santa Clara, California). RI7100A systems are typically repaired while on the customer site.

Handler Integration
