Figure 4. Remote Terminal Block Diagram - Monitor Mode Operation
The Total-AceXtreme® Monitor engine provides the next generation DDC MIL-STD-
1553 Monitor (MT) architecture. This new Monitor autonomously stores individual
messages into a contiguous memory stack formatted as IRIG 106 Chapter 10 Data
Packets.
The legacy Monitor modes of operation traditionally implemented in previous
generations of DDC MIL-STD-1553 engines can be emulated easily through host
software. All information and functionality supported on the legacy Monitor engines is
supported on the AceXtreme Monitor engine, or may be extracted from the stored
messages.
IRIG 106 Chapter 10 provides interoperability for such applications as test range
telemetry, flight test instrumentation, mission recorders, video/data servers;
surveillance and reconnaissance; health and usage monitoring; mission planning,
debriefing, and training; and flight operations. IRIG 106 Chapter 10 defines a
standardized file format, and within that specific representations for several types of
flight data, including MIL-STD-1553 buses, PCM, analog, computer-generated data,
