Overview

The AXI1553-1/2 module is part of a new family of VXIbus cards offering full function test, simulation, monitoring and databus analyzer functions for MIL-STD-1553A/B applications. Two independent and dual redundant MIL-STD-1553A/B databus streams are provided on the AXI1553-2 module and one dual redundant MIL-STD-1553A/B databus stream is provided on the AXI1553-1. The AXI1553-1/2 can be used for protocol testing and simulation of MIL-STD-1553A/B Bus Controller, Multiple Remote Terminals and Chronological Monitoring at full bus load. All operations are performed concurrently with no degradation of performance in any operating mode. The AXI1553-1/2 module incorporates full protocol error injection and detection features with software programmable output amplitude and bus coupling modes of the electrical bus signals.

The module fully supports the protocol testing requirements defined by the RT and BC production test plans according to SAE-AS 4112/4114. An on-board IRIG-B time decoder and generator allows users to accurately synchronize single or multiple AXI1553-1/2 modules to a common time source.

The use of an Application Support Processor (ASP) executing the Driver Software allows user specific functions to be processed on-board, significantly off-loading the host processor. This new concept allows users to implement application-specific system level functionality on a single interface card. To provide I/O and processing expansion capabilities, a PMC slot is available on the AXI1553-1/2 module.

The AXI1553-1/2 uses a ´Common Core´ hardware design utilizing multiple RISC processors. A Physical Bus Interface (PBI) daughter board provides MIL-STD-1553A/B bus connections including a resistive terminated bus network.

The AXI1553-1/2 module is a register based device and can be easily integrated into VXI systems as an off-the-shelf module supported by a VXIplug&play driver software package. Furthermore the AXI1553-1/2 operates with the optional PBA-2000 Databus Analyzer Software for Windows 95/98 and NT.
