• Summary

    FireSpy® 450b(T)/850

    The FireSpy450b, FireSpy450bT and FireSpy850 bus analyzers complete the second generation of 1394 analyzers offered by DapTechnology. Based on the industry leading FireSpy800, the all new and enhanced architecture of the FireSpy810, as well as the form factor advantages introduced with the FireSpy3850, make these PCI form factor analyzer cards the most compelling package for card-based 1394 analysis solutions found in the industry.

    The PCI format takes flexibility to a higher level. This solution enables users to install the FireSpy hardware in any PC that has at least one PCI slot available. This allows for installation of the FireSpy Analyzer in developers’ existing PC’s, rugged field service laptops or lunchbox computers.

    The FireSpyx50(bT) are equipped with 1GB of on-board memory. The units offer extensive hardware filtering and trigger possibilities due to efficient programmable logic and an on-board processor. They support up to 800Mb (400Mb for the FireSpy450b) transfer rates and are fully IEEE 1394b compliant. Three bilingual or Beta 1394 ports (depending on model) allow for convenient connection to the system under test. As an added feature the FireSpy450b uses dip-switches to conveniently allow the changing of PHY port speed/mode settings.

    The graphical user interface runs on WindowsTM Operating Systems. It is intuitive and offers a user friendly way of data presentation and user control. Additionally, the included API even allows you to build your own control software or interface using C/C++ or LabVIEWTM. The seamless integration of the AS5643 protocol makes the FireSpy850 or the FireSpy450b an ideal tool for many Aerospace & Defense development tasks. For long distance applications DapTechnology also offers the FireSpy450b in an impedance matching transformer configuration, i.e. the FireSpy450bT.

      • 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.
