AVX1553-4

Quad Stream, Dual Redundant VME bus to MIL-STD-1553A/B Interface

The AVX1553-1/2/4/8 is a member of AIM’s new (fourth generation) family of advanced VME bus modules for analysing, simulating, monitoring and testing MIL-STD-1553A/B databuses. The AVX1553-x modules concurrently act as the Bus Controller, Multiple Remote Terminals (31) and Chronological Bus Monitor / Mailbox Monitor.

A full range of MIL-STD-1553A/B protocol errors can be injected/ detected. The AVX1553-x cards can electrically reconstruct and replay previously recorded MIL-STD-1553A/B record files physically to the MIL-STD-1553A/B bus with excellent timing accuracy. The AVX1553-x offers an interface for 1, 2, 4 or 8 dual redundant bus streams. All versions are 6U VME-module card formats.

The AVX1553-x card uses AIM’s Next Generation ‘Common Core’ (NCC) hardware design utilising multiple RISC processors with up to 32MB of global RAM and 128MB of ASP RAM. The use of an onboard Application Support Processor (ASP) runs the Driver software on the card minimising the host PC interaction. The use of onboard processing and large memory enables autonomous operation with minimal interaction with the host PC for real time applications.

An onboard IRIG B time encoder/ decoder is included having a sinusoidal output and free wheeling mode for time tag synchronisation on the system level using one or more AVX1553-x cards. The Physical Bus Interface (PBI) Daughter board provides programmable bus coupling modes and variable Output Amplitude to the MIL-STD-1553A/B bus.
