Multichannel High Performance 1553 Mezzanine Module

Overview:

The AT-XMC/PMC-1553 is the latest generation of high performance, multichannel Mezzanine module for MIL-STD-1553B, with a choice of either PCIe or PCI as the Bus interface. The card provides up to four flexible single function, 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 (Appli¬cation 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 MIL- STD-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 modules to a common time source.

The module is available in either Air-cooled and Conduction cooled versions. Conduction cooled versions for rugged on-board systems.

Hardware:

The AT-XMC/PMC-1553 module 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 AT-XMC/PMC-1553 card’s single function architecture emulates 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 the transformer- coupled mode or in the direct-coupled mode. Jumpers are provided on the cards to select the mode. It is configured to work in the transformer-coupled mode by default.

Digital I/O Channels

The card is equipped with 16 TTL/CMOS level digital I/O channels. These are pre-configured as 8 inputs and 8 outputs. These can be used to generate an interrupt on any type of level shift event.

SOFTWARE:

The AT-XMC/PMC-1553 software includes:
Drivers & APIs
The cards come 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.

Benefits

• Choice of XMC or PMC backplane
• Powerful protocol engine relieves host
• Mixed protocol saves system spaceintricacies.

Applications

• Rugged deployed systems
• Embedded test systems
• High performance simulators

• Mixed protocol systems
• Avionics upgrades and retrofits
• Databus health monitoring

IRIG-B Time Code
An onboard IRIG-B time code encoder and decoder allow synchronization of XMC/PMC 1553 modules to a common time source. Multiple modules can be synchronized using one common IRIG-B time source. The onboard time code generator of one XMC/PMC1553 module can be used as reference for accurate correlation of data across all 1553 channels.

Driver and high-level API libraries for Windows XP, Windows 7 and Linux are available. Sample programs for BC, RT, MT modes are included.
