The AT-PC104-1553 card provides a flexible, Single function, dual redundant MIL-STD-1553B interface to the PC/104 embedded bus. It provides the highest level of performance & flexibility for MIL- STD-1553B protocol on the PC/104 bus. The AT-PC104-1553 offers Simulation & Monitoring functions. The card comes integrated with powerful software that reduces application development time. All data bus functionality is supported by our advanced API (Application Programming Interface).



The AT-PC104-1553 card’s single function architecture emulates a Bus Controller or 31 Remote Terminal or Monitor Terminal modes. Polling and interrupt generation is also provided.

Transformer and Direct Coupling
The card can be configured to work either in the transformer-coupled mode or in the direct-coupled mode. Jumpers are provided on the cards to select the mode. It is configured to work in the transformer-coupled mode by default.


The AT-PC104-1553 software includes:
> Drivers & APIs
> Bus Monitor

Drivers & APIs
The cards come with a powerful set of library functions to access the entire MIL-STD-1553B functionality. The drivers are designed in a modular fashion consisting of component functions and application functions. The user’s test program can be developed with few calls to the driver by using the set of application functions provided. Driver and high-level API libraries for DOS, Windows 2000 are available. Sample programs for BC, RT, MT modes are included.
