FireSpy® 3850/3852

The Triple Series PCI hosted FireSpy 3850, 3851E and 3852 provides three FireSpy bus analyzer engines in one compact package. Designed to meet the requirements of AS5643-based triple-redundant bus architectures, all the FireSpy385x products allow to be connected to three separate IEEE-1394 buses while connecting to three synchronized analysis engines. Based on our 2nd generation hardware platform, the FireSpy385x products contain 1GB internal memory and a powerful processor to provide the resources needed to service all three buses. The 32-bit PCI 2.1 host interface allows communication with the FireSpy to be much faster than similar products with USB 2.0 or Ethernet interfaces.

The FireSpy3850 brings out six active transformer coupled ports, two from each bus analyzer engine, through a single high-density (VHDCI) connector to six IEEE-1394 Beta 9-pin cables. Additionally, it has three, one from each bus analyzer, IEEE-1394 bilingual 9-pin connectors.

The FireSpy3851E is the same as the 3850 except it provides mechanical support to help stabilize the VHDCI connection.

The FireSpy3852 brings out six active transformer coupled ports, two from each bus analyzer, to 6 LEMO connectors.

The AS5643/1 active transformer coupled ports can only operate at S400 and S800 Beta mode data rates, while the bilingual ports can operate in S100, S200 and S400 legacy mode and S400 and S800 Beta mode.

The FireSpy385x products utilize the same FireDiagnostics Suite™ software as all other FireSpy bus analyzers. However, all three bus analyzer engines are presented in a single GUI. FireDiagnostics Suite™ software supports Windows™ Operaing Systems. Additionally, the FireDiagnostics Suite API allows you to build your own control software using C/C++ or LabVIEW™.

The seamless integration of the AS5643 protocol makes the FireSpy385x products the preferred tool for many Aerospace & Defense development, testing and product qualification tasks. DapTechnology has made considerable efforts to fully support the SAE AS5643/Mil1394 protocol in all major functional areas of the FireSpy385x and continuously updates the analyzer functionality according to implementation requirements and ongoing standardization efforts.
