The BIM-553-8 is a 1-channel dual-redundant MIL-STD-1553 bus monitor card for use in TTC’s EDAU-20XX or CDAU-20XX products. The card supports data transmission as standard fixed-position PCM output from the host unit (per IRIG-106, Chapter 4), and simultaneously for transmission through a CMP-112 card as highspeed composite data (per IRIG-106, Chapter 8). The card supports either direct or transformer coupling under user-program control. High time, low time, and micro timestamping are provided on a per message basis. The card provides optional tracksplit outputs and accepts one 16-bit user word input.
