The card provides up to four flexible single functions, dual redundant MIL-STD-1553B channels. It provides the highest level of performance & flexibility for MIL-STD-1553B protocol on the PCIe bus. The AT-XMC/PMC-1553 card includes advanced API (Application Programming Interface) software that reduces application development time. Standard features include 64K Words of RAM per channel, 48-bit message time tagging, up to four independent dual redundant MILSTD- 1553 channels, Six Discrete Inputs & Six Discrete Outputs, IRIG-B Time Code Input/Output. An onboard IRIG-B time code decoder and generator allow users to accurately synchronize single or multiple XMC/PMC1553 cards to a common time source. The card is available in either Air-cooled and Conduction cooled versions. Conduction cooled versions for rugged on-board systems.

 

HARDWARE

The AT-XMC/PMC-1553 card offers full-function test, simulation, monitoring, and data-bus analyzer functions for MIL-STD-1553B applications. These high-density high-performance cards are suitable for applications ranging from test equipment to rugged deployable systems. The card comes integrated with powerful software that reduces application development time. All data bus functionality is supported by our advanced API (Application Programming Interface). The card’s single function architecture emulate a Bus Controller or 31 Remote Terminals or Monitor Terminal, BC/MT, or Multi-RT/MT modes independently per channel. Standard features include Programmable coupling and bus termination, extensive BC frame structures, error detection, RT Status Bit and Mode Code responses along with advanced BC functionality, Polling and interrupt generation. The advanced BC architecture provides a high degree of flexibility and autonomy by providing Major and Minor frame schedule control, streaming data interface, asynchronous message insertion, bulk data transfers, double buffering, message retry, bus switching strategies, data logging, and fault reporting. The RT architecture provides flexibility in meeting all common MIL-STD-1553 protocols while emulating up to 31RT addresses on one 1553 channel. The card includes a message monitor mode and a combined Multi-RT/ MT mode where the MT can monitor all 1553 communications on the bus, including the 1553 channel’s assigned RT addresses. The Bus Monitor mode provides complete error detection on100% fully loaded buses, advanced error detection to isolate faults at a particular word within a 1553 message.

Transformer And Direct Coupling
The card can be configured to work either in transformer-coupled mode or direct-coupled mode. Jumpers are provided on the card to select the mode. It is configured to work in the transformer-coupled mode by default.

SOFTWARE

The AT-XMC/PMC-1553 software includes Drivers & APIs. The card comes with a powerful set of library functions to access the entire MIL-STD-1553B functionality. The drivers are designed in a modular fashion consisting of component functions and application functions. The user’s test program can be developed with few calls to the driver by using the set of application functions provided.
