SALT LAKE CITY, UTAH — parvus Corporation today launched a new PC/104 board as part of its VersiNet communication products line - the parvus PC/104 1553 Dual Interface Board.

The module provides systems engineers with a powerful new option for interfacing between MIL-Std-1553 avionics data busses and the rugged, compact PC/104 bus platform.

The PC/104 1553 Dual Interface Board provides an interface from its two dual-redundant 1553 buses to any standard PC/104 computer system bus. The 1553 Dual card features two United Technology SuMMIT 1553 support chips and eight 16-bit register locations within the SuMMIT and the Pseudo Dual Ported Memory (PDPM), allowing complete access to interface functions through PC/104 I/O space.

Software, including programmed I/O instructions (supplied with the 1553 Dual Interface Board) can be used to access the PDPM and internal registers, and can also be used to transfer data to and from the PDPM using Direct Memory Access (DMA).

The SuMMIT chip can also cause interrupts to be generated and routed to the PC/104 processor. The 1553 Dual Board is designed for transformer-coupled stubs as specified in MIL-Std-1553B, supplied by the user. The onboard PC/104 processor can be used to access a 1553 bus to configure it for Remote Terminal (RT) mode, Bus Control (BC) mode, or Monitor (MT) mode.
