Bus Controller, Remote Terminal and BUS Monitor
Terminal Unit (RTU) and Bus Monitor (MT). Packaged in a hybrid plug-in or flatpack, the CT2561
performs all the functions required to interface a MIL-STD-1553 dual redundant serial data bus such
as ACT4487 and a subsystem parallel three-state data bus.
functional CT2565 compatibility, user initiated self-test, and low power consumption.
and uses direct memory access (DMA type) handshaking for subsystem transfers. All message
transfer timing, DMA and control lines are provided internally, thereby reducing the subsystem
overhead associated with message transfers.
code may (Optionally) be legalized through the use of an external PROM. Complete error detection
is provided by the CT2561 for BC and RTU operation. Error detection includes: response time-out,
inter-message gaps, sync, parity, Manchester, word count and bit count.
