Each 1553 channel can emulate as a Bus Controller (BC), a Remote Terminal (RT) or a Bus Monitor (MT). Standard features include 64KB of RAM per 1553 channel, transformer & direct coupling, triggers, extensive BC & RT frame structures, RT Status Bit & Mode Code responses, along with advanced BC functionality. The advanced BC architecture provides a high degree of flexibility & autonomy by providing message schedule control, minimizing host overhead for asynchronous message insertion, facilitating bulk data transfers, double buffering, message retry, bus switching strategies, data logging & fault reporting. The RT architecture provides flexibility in meeting all common MIL-STD-1553B protocols. The choices of RT buffering & interrupt options provide robust support for synchronous & asynchronous messaging, while ensuring data sample consistency & supporting bulk data transfers. The interface includes a message monitor mode & a combined RT/MT mode where the MT will monitor all 1553 communications on the bus including the 1553 Channel’s assigned RT addresses. The Bus Monitor Mode provides for Selective Message Monitoring & Combined RT/Message Monitor Mode. Besides providing monitor filtering based on RT address, T/R bit & sub address, the message monitor eliminates the need to determine the start & end of messages by software. A combined RT/MT mode allows the device to run in both modes of operation at the same time on the bus.
The device includes 16 (digital 5V) discrete that are individually programmable as inputs or outputs (Open/Ground Discrete). The discrete outputs can be used for a variety of purposes, including triggering events, indicating status & general purpose use.
AT-ETH-1553 module provides interface between non 1553 compatible device to 1553 bus system & this can be achieved through Ethernet interface. This feature allows the unit to operate in stand-alone mode in either BC or RTor MT. Firmware allows the User to dynamically reconfigure the unit to one of the supported modes.
The device comes with a powerful set of library functions to access the entire MIL-STD-1553B functionality. Sample applications will be provided to help users quickly setup & use the card. Sample programs for BC, RT, MT modes are included. Sample applications for Windows, Linux & RT-Linux are included.
