• Summary

    FireSpy® 422bT/822bT

    The FireSpy422bT and FireSpy822bT bus analyzers are DapTechnology's latest single-bus IEEE-1394 protocol analyzers. Based on the 4th generation FireSpy analyzer architecture the FireSpy422bT/822bT is the most advanced 1394 test equipment in the market. They comprises a significantly more powerful on-board processor and improved connectivity to the host.

    The seamless integration of the SAE AS5643 protocol makes the FireSpy422bT/822bT the preferred tool for many Aerospace & Defense development tasks. DapTechnology has taken considerable efforts to fully support the AS5643 protocol in all major functional areas of the FireSpy422bT/822bT and continuously updates the analyzer functionality according to implementation requirements and ongoing standardization efforts.

    4th Generation Hardware

    In order to to keep up with the growing data analysis needs this new generation of 1394 bus analyzers has been completely re-architectured.

    The FireSpy422bT/822bT have a single 1394 node connected to one analysis engine. It are controlled by a dual core ARM processor running at 667MHz. The node is connected to three 1394 ports. All ports are connected to a 1394 bilingual connector in compliance with the 1394 standard.

    The FireSpy3422bT/3822bT are equipped with 5 GB internal memory and extensive hardware filtering and trigger possibilities. The analyzer can be connected into a host computer using its PCIe interface. On the host you can control the FireSpy using a graphical user interface to analyze and display the bus traffic in a user-friendly way; or you can use the API to program your own control software.

    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 analyzer tools like Monitor, Recorder, Generator, Commander, Scriptor and Mil1394 Signal Monitor, the suite also offers a set of software tools designed to allow the integration of the FireSpy products in a wide variety of testing applications, as well as extend customization of its functionality beyond the baseline feature set provided by DapTechnology.

    FireSuite API

    The foundation for all software tools included in the FireDiagnostics Suite is formed by the Application Programming Interface (API). With its interfaces for a wide range of development environments using C/C++ or LabVIEWTM on WindowsTM Operating Systems, the application of FireSpy analyzers is extremely flexible. With its feature-rich function library, all hardware assisted analyzer tools like the Monitor and Recorder can be controlled as well as more low-level 1394 bus functions.

    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.
