BMC's PCI-CRAM-MRT-1553 provides new levels ofperformance and flexibility for MILSTD1553A/B Notice II for PCI form factors. Available in commercial and ruggedized versions, the


includes an API (Application

Programming Interface) software that reduces application development time.


Standard features include 32 Kbyte of RAM, 32-bit message time-tagging, triggers, extensive BC & RT link-list structures, error injection/detection, automatic/manual RT Status Bit, Mode Code responses, advanced BC functionality, on-board Built-in-Test Bus, transformer & direct coupling, hardwired RT address. With the highest speed encoder/decoder in the industry, the PCI-CRAM-1553 Bus Monitor provides unparalleled error detection and monitoring of fully loaded buses.


Multi-function Interfaces

PCI-CRAM-MRT-1553 multi-function interfaces are easily software configured to operate with simultaneous Bus Controller, 8 Remote Terminals and Bus Monitor functionality.


Single-function Interfaces

Single-function PCI-CRAM-MRT-1553 interfaces have all the features and functionality of the multi-function versions, but with only one operational mode enabled at a time. Each interface can emulate either a Bus Controller or 7 Remote Terminals or Bus Monitor.



The 1553 API is provided in source code, along with integrated support for Windows XP, 2000, Me, NT, 98, 95, Visual Basic and other operating systems.
