1394 and AS5643 Bus Monitor - FireProbe3403bT/3413bT

FireProbe® 3403bT

The  FireProbe3403bT is the first product in the second generation of DapTechnology’s FireProbe family. It represents the standard configuration within the series and is engineered to support a broad range of functional profiles through its dedicated hardware and firmware architecture

The default configuration includes:

  • D38999 bus connectivity
  • Three IEEE-1394 bus nodes
  • Two active, transformer-coupled ports per PHY
  • Dedicated hardware for timestamped recording of all IEEE-1394 bus traffic
  • Hardware-supported IEEE-1394 and AS5643 protocol-level transaction monitoring
  • Design Compliance
    • MIL-STD-810
    • MIL-STD-461
       

Data Protection

Given the growing importance of cybersecurity, traditional data transfer methods—such as USB-based connectivity used to upload captured data to a host system (e.g., an analysis PC)—are increasingly restricted or prohibited in many aerospace programs.

To address this challenge, DapTechnology has developed a secure approach for transferring large volumes of captured data without compromising data protection. The FireProbe platform supports secure data offload while maintaining strict cybersecurity requirements.

In addition to standard NVMe SSD storage with built-in encryption, the FP3403bT can also be operated with FIPS-140 validated encrypted NVMe drives, enabling secure end-to-end handling of recorded data.

Disk Access

By simply opening the hinged drive protection bay, the NVMe drive can be easily removed from the FireProbe. The drive can then be transferred to a secure environment and decrypted in a compatible drive bay connected to a PC or laptop via USB.

Once connected, the captured data can be analyzed using the feature-rich FireDiagnostic Suite in standalone mode—a workflow already familiar to many FireSpy users.

Enclosure

For this FireProbe variant, DapTechnology has chosen a rugged enclosure that balances durability, environmental protection, and usability. Rubber corner shock absorbers provide reliable impact protection, while the overall design ensures the unit can withstand outdoor and harsh environmental conditions. The ruggedness of the enclosure meets MIL-STD-810 and MIL-STD461 standards, making it suitable for demanding field applications.

FireProbe Software

Leveraging the field-proven FireSpy® Software, the DapTechnology control panel technology has been optimized for use in the FireProbe embedded software environment. By design, the FireProbe user experience is highly customizable with regards to visualization and control elements to match specific user needs. The chosen design provides a highly customizable framework and the tools to tailor towards specific operator tasks.

The Graphical User Interface (GUI) builder PC tool can be used to create and modify operator specific screens for specific and unique operator tasks. Enabling our customers to build operator specific data views will result in better data-protection, higher operator productivity and lower training cost. This operator specific customization can be done by the customer supported by DapTechnology’s partners (DapUSA). The benefit of this approach is that only FireProbe configuration files will be exchanged between the configuration environment and the FireProbe device by using the NVMe SSD as transportation medium.

The required know-how of the specific aerospace program can not only be kept at a minimum but also geographically contained, which is of critical importance when dealing with export-controlled information. The idea is that none of this controlled information needs to flow back to DapTechnology's design team but can be entirely handled by DapUSA Inc. (fully US owned, US staff only, NIST800-171 compliant) as a contracted design service. 

Another important aspect is that the mentioned configuration files are always encrypted and cannot be altered on the FireProbe device themselves or on any other device. So no FireProbe user can access information that he has not been authorized to. This creates an extremely efficient mechanism for data protection but also for limiting the depth of information presentation.

 

FireDiagnostics Suite

The FireDiagnostics Suite is the most comprehensive collection of 1394 analysis, simulation and interface tools for a wide range of applications. Apart from well established and hardware assisted FireSpy analyzer tools like Monitor, Recorder, Generator, Commander, Scriptor and Mil1394 Signal Monitor, the suite also offers a set of software tools designed to work in a stand-alone mode (i.e. without a FireSpy analyzer connected). In this mode the Suite is able to open and analyze data sets captured by compatible devices and in particluar FireProbe. 

Protocol Support

A cornerstone of FireDiagnostics Suite functionality is the unparalleled level of support for high-level protocols. With IEEE-1394 being the basic data exchange mechanism application specific protocols for the PC & storage environment (IPv4, SBP2), consumer electronics (AV/C, HAVi), Automotive Infotainment (AMI-C), Industrial Imaging (IIDC) have been successfully deployed. In recent years AS5643 has been adopted for use within Aerospace and Defense and largely fueled the continuous growth of IEEE-1394.
