BIM-553A-8 Dual-Redundant MIL-STD-1553 Monitor - Ch 8/4 Compatible

The BIM-553A-8 is a dual-redundant MIL-STD-1553 bus monitor module for use in Curtiss-Wright’s EDAU/CDAU-2000 series products. The module supports either direct or transformer coupling under user program control. High time, low time, and micro timestamping are provided on a per-message basis. All incoming 1553 messages are temporarily buffered on the module and can be selected by the user for transmission in the PCM output format as “Class I PCM” (standard fixed-position), and as “Class II PCM”, and for transmission through a CMP-112 module as high-speed composite data (per IRIG 106, Chapter 8). Note that the BIM-553A-8’s IRIG “Chapter 4” capabilities can be used independently from the module’s IRIG “Chapter 8” capabilities.

For example, a BIM-553A-8 module can be used to support Chapter 4 data only for selected data and embedded Chapter 8 within Chapter 4. However, for the module to support a dedicated IRIG 106-96, Chapter 8 data stream, the module must be used with a CMP-112 module and must have a module ID set for any valid value ranging from “0” through “7”. The card also provides a fully programmable PCM tracksplit output in accordance with IRIG 106, Chapter 8 requirements.
