MIL-STD-1553 Channels

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.

Discrete I/O
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.

Stand-Alone Feature
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.

Software
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.
