SES Solid State Data Recorder - Compact Plus

The S3DR product family is a low cost, high performance, rugged solution to the processing and data recording needs of environmentally challenging embedded system, such as those found in aerospace, defence, naval and safety-related or high performance industrial applications.

 

The S3DR product family is designed with flexibility and expandability in mind. S3DR-C+ (Compact Plus) is a specialisation of the more generic product family providing communications, data acquisition and data recording functions where space and mass are at a premium. The unit features a high-speed solid state memory recording function, that is able to write data to memory media from multiple monitored interfaces at combined speeds of up to 60 Mbits (7.5 Mbytes) per second.

The S3DR-C+ supports PCMCIA style high capacity solid state cartridges (with max storage capacity 16GByte).

The S3DR-C+ is extremely configurable through the presence of an onboard embedded computer and flexible FPGA, allowing application specific data gathering regimes and various I/O options to be accommodated.

Typical applications of S3DR-C+ include use as flight test recorder, Quick Access Recorder, engine test data acquisition unit or incident investigation recorder. Typical configurations can be specified focusing on IRIG106 PCM, Data bus, Ethernet or Voice monitoring.

  SES Solid State Data Recorder - Compact Plus: Interfaces

Three circular military connectors are utilised, and are sealed against sand, dust and fluids. One of these connectors is always power, the other 2 connectors provide 20 I/O pins that can be used to select the required functionality of the S3DR-C+.

Wide input range power supply (11-32V, 5 Watt at 28V nom.) tested to BS3G100 and Mil-Std 704F, providing all power conditioning for internal supplies. (Power requirements depend on configuration, typically < 5W)

Hot-swappable solid state removable memory module (PCMCIA ATA Flash format).

Can be configured for "continuous loop" recording, or "one-off" continuous recording which can start from power-on, from discrete input or from an external trigger.

  SES Solid State Data Recorder - Compact Plus: Memory

The S3DR-C platform offers several data recording media systems, including:

• Solid State Removable Memory Module
  
  
  
  S3DR-C+ utilises high speed, high capacity PCMCIA ATA flash, providing low-cost high-performance removable media, with the added advantage that they can be read using a standard laptop, or a special high-speed reader.SES have qualified a number of extended performance PCMCIA ATA flash cards which can be used with S3DR-C+, but the recommended solution is to use SES own design of solid state removable memory modules. These have extended environmental performance and functionality, which when used in conjunction with an SES recorder, provide optimal performance.
  SES solid state removable modules are available in the following capacities 256MB, 512MB, 1GB, 2GB, 4GB, 6GB, 8GB and 16GB. All SES cartridges are environmentally enhanced to achieve exceptional environmental performance:
  • Performance:

SES Multi-Channel Video and Data Recorder: Support

SES provide a number of optional support items to maximise the potential of the S3DR-MVDR platform, including:

• REVEAL

REVEAL is a partner product to the S3DR-MVDR data recorder. It allows the user to extract and manipulate data from a removable memory cartridge and prepare the cartridge for reuse by the S3DR-MVDR. REVEAL is an application for Microsoft Windows that provides a wealth of features for extracting, interpreting, visualising and analysing data captured using an SES data recorder. Key features of the tool include:

• Convert data to a variety of formats to allow analysis with domain specific tools
• Interpret data to demultiplex or decommutate a data stream into its constituent parameters
• Archive data to hard disk, CD or DVD for later analysis or long term storage
• Visualisation of data to allow visual analysis within REVEAL using a framework that supports real-time and fast-time playback where suitable hardware is available
• Declassification of S3DR data storage media
• Annotation of recorded data with supplementary data, for example Form 725

The architecture of the application allows for easy customisation of the application to suit bespoke requirements, for example introduction of a new component to output data in a new format. Alternatively, the underlying components can be reused to provide a bespoke application to automate the extraction and processing of S3DR data cartridges.
