The FireTrac 3445bT and 3845bT feature the FireTrac® family functionality in the widely used XMC mezzanine card form factor. They use the latest versions off-the-shelf PHY layer silicon (TSB41BA3/TSB81BA3) together with Dap's FireLink® Extended IP Core.
The HW also provides IRIG time-stamping of monitored events and accepts IRIG-B122 and IRIG-B002 inputs.
*) Depending on exact model
For this version of FireTrac® DapTechnology uses a rather traditional SCSI2 connector. Main reason is the form factor and high pin count together with a good signal quality which is so essential for high-speed low-voltage differential data transmissions.
The connector allows to route all bus connections (A0-A2, B0-B2, C0-C2) together with 3 trigger signals as well as the IRIG sync input.

In order to get the best out of the unique feature set of the FireTrac card DapTechnology recommends using the hardware in combination with FireStack, i.e. DapTechnology's home grown software stack.
FireStack optimally supports the hardware and firmware layers embedded into FireTrac. As FireTrac's host interface uses FireLink Extended (and not a standard OHCI Link Layer chip) functionality that has been tailored and optimized for the support of the AS5643 standard brings the combination of FireTrac and FireStack to an entirely new level.
The objective of FireStack’s® 1394 packet handler is to reduce resource burden when receiving and transmitting 1394 packets. The consistent utilization of zero-copy operations greatly enhances the overall system performance. FireStack® provides memory buffers accessible by both the user application and the 1394 Link Layer DMA engine.
For example, when transmitting an asynchronous packet and the user application has filled the memory buffer with the needed packet data, FireStack® will hand the buffer directly to the Link Layer for reading the packet into the packet transmission FIFO without having the CPU copy memory to memory.
Likewise, displaying a video stream from an IIDC camera only requires creation of DMA-capable reception buffers for the video frame data and registration of notification upon filling of a complete frame. Once notified the buffers holding the received data can be accessed directly by the video rendering engine in order to move the data to video card memory.
Inbound Transactions (handling of incoming requests) are defined in two separate methods:
Map Local Memory: The user can "map" a memory buffer to a specific address space. The contents of the memory buffer can be accessed by the user application at any point in time. At the same time when the stack receives a request packet from a remote device it will automatically perform the response operation (read, write or lock) and will send a response packet back to the requester. The user has the option to be notified by the notification callback function when the transaction completes.
Transaction Handler: Similar to the Map Local Memory above the user can "register for" a specific address space instead of "mapping" local memory. When the stack receives a request packet it will call the user-specified handler callback function. The user can then perform any operation within the callback function. Upon returning from the handler callback, the FireStack® may transmit a response packet. The notification callback function will be called after completion of the response process.
This module can be used to perform memory transactions (read, write, lock) on remote nodes. When a memory transaction is initiated FireStack® will automatically determine the maximum speed to the destination node by performing the needed PHY remote accesses.
Outbound Transactions can be used in the following ways with respect to result indication: In Blocking mode the TX functions will not return until the response packet is received and thus making the code sequential. In contrast to that the Non-Blocking mode can be used to initiate a series of “split” transactions i.e. a series of requests that are then followed by the corresponding - but not necessarily sequential - responses.
The Isochronous Streaming modules build on the mechanisms for efficient data processing defined by OHCI and provide a flexible and user-friendly API around it. Linked lists of buffers can be setup by the user application and will be automatically processed by the Link Layer DMA engine. Notification mechanisms are available for buffer and/or packet completion.
An essential feature of FireTrac® is its thin software and firmware layer. In order to be usable in embedded designs having limited resources, great emphasis was given to keep the footprint and host system resource utilization as small as possible. And, in order to optimize and streamline performance, the individual features and functions of FireTrac® are grouped into so-called Personality Profiles. These profiles may be purchased separately so that the user may configure their system based on individual requirements.
The Personality Profiles allow the solution to be adapted for use in embedded systems which typically have limited resources, and/or with powerful host processors that can utilize even the fully featured profile.
The following profiles are available:
The SAE-AS5643 protocol differs from other 1394 protocols because of its stringent timing requirements. Because of potential inaccuracies and unpredictable latencies possible with software implementations, DapTechnology strongly believes that the AS5643 protocol timing is best implemented via a HW extension in the 1394b Link Layer. Therefore, DapTechnology has added the AS5643 protocol timing into FireLink® Extended as an integral module. With this HW support FireLink® Extended is easily capable of meeting the AS5643 frame timing requirements and eliminates the need for complicated interrupt schemes or real-time operating systems typically needed to efficiently use the AS5643 protocol.
The FireStack® software library contains an AS5643 protocol module that can be used to control the AS5643 hardware of FireLink Extended enabled products (e.g. the FireTrac I/O card). Optimized frame timing can be configured and used for both timed transmission and reception.
Frame Timing: FireStack® is very flexible in the way it handles the timing of Start of Frames. Frame synchronization for AS5643 reception and transmission may be configured as either:
In addition to acting as a synchronization “slave”, it is also possible for each bus to act as STOF master and output a sync pulse on an External Sync Pin.
Reception: AS5643 reception provides a filtering mechanism and all incoming packets will be run against a comprehensive verification system. Messages can be filtered on channel number, AS5643 message ID or a combination of both.
Transmission: AS5643 Transmission module can be used to control devices that support AS5643 timed transmission in. FireTrac® offers very accurate transmission timing. The following transmission modes are available:
Streaming messages: Allows writing large or small sets of messages to FireStack® and having them transmitted automatically at specified frame offset times. The provided data needs to contain so called frame separator elements to indicate that the following message needs to be transmitted in the next frame.
Repeating messages: Allows setting up a message that will automatically be transmitted each frame by FireTrac hardware. The user will have a pointer to the actual data of the message and is allowed to manipulate the data at any point in time without having to worry about its timed transmission. This is very useful for AS5643 status messages.
Single messages: Allows simply transmitting a message as soon as possible but exactly at the specified frame offset time. Several messages may be handed to the FireStack® for immediate transmission and the FireStack® will then take care of the actual moment of transmission.
STOF Messages: Allows controlling transmission of STOF messages.
Manual available on request
In order provide a wide variety of connectivity options – either to additional FireTracs or to other AS5643 equipment, DapTechnology is offering a series of harnesses / interconnectivity options. The versions below highlight the most commonly used variants.
However, it needs to be pointed out that other variations (e.g. different connector type) can be very easily built as well and therefore to not fall under the category "custom designed". For example, the 19”-breakout panel as depicted below offers an extremely flexible way to connecting bus devices via 1394b bilingual sockets. Such a “patch”-panel can also be configured with LEMO or 38999 sockets depending on the customer’s interconnectivity preferences. Or the "Spider"-cable can be easily built with bilingual or 38999 sockets or plugs.
