USB connector
The FireSpy must be connected to the computer using this connector. A USB cable, which is part of the
FireSpy-package, is connected between this connector and the USB port of the computer.
The USB interface is electrically isolated from the IEEE1394b logic to prevent ground loops.
serial number
Each FireSpy has a 5 character serial number. This number is also programmed into the FireSpy and can
be read with the License Manager of the FireSpy application. Part of the software will only work when
license keys are installed for the serial number of the currently connected FireSpy. See
License Manager
for more information on license keys.
24.3.2. FireSpy 3850, 3851
The FireSpy385x bus analyzer is world’s only PCI –based multichannel FireWire bus analyzer. Based on
the industry leading FireSpy810 architecture the FireSpy385x is the most advanced IEEE 1394 test
equipment in the market. The FireSpy385x in fact
combines three FireSpy analyzers in one single instrument. It comprises a significantly more powerful
on-board processor and improved connectivity to the host.
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 in
developers existing PC’s or installing the analyzer in a rugged field service laptop or lunchbox computer.
The FireSpy385x has three 1394 nodes connected to three synchronized analyzer engines. They are
controlled by an onboard RISC processor running at 400 MHz. Each node is connected to three FireWire
ports. One port of each node is connected to a separate standard bilingual FireWire connector.
The other two ports of each node are connected to one high speed connector and include active
transformer coupling.
The FireSpy385x is equipped with 1 GByte memory and extensive hardware filtering and trigger
capabilities. 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 and program your own control
software.
The seamless integration of the SAE AS5643 protocol makes the FireSpy385x the preferred tool for many
Aerospace & Defense development tasks. DapTechnology has taken considerable efforts to fully support
the SAE AS5643 protocol in all major functional areas of the FireSpy385x and continuously updates the
analyzer functionality according to implementation requirements and ongoing standardization efforts.
