1-, 2- or 4-channel MIL-STD-1553 module for PCI backplanes

QPCX-1553 PCI Module


Abaco Systems' QPCX-1553 provides new levels of performance and flexibility for MIL-STD-1553A/B Notice II for PCI backplane form factors. Now faster, the QPCX also draws less power in a smaller board footprint.

Available in commercial and ruggedized versions with one, two or four dual-redundant channels, the QPCX-1553 includes an abstract API (Application Programming Interface) software that reduces application development time.

Standard features include 1 Mbyte of RAM per channel, 64-bit, 25 nanosecond message time-tagging, triggers, extensive BC & RT link-list structures, error injection/detection, automatic/manual RT Status Bit, Mode Code responses, advanced BC functionality, IRIG-B signal Receiver/Generator, on-board Test Bus, UUT transformer connection, 1760 startup time with Busy bit set and hardwired RT address lines. With the highest speed encoder/decoder in the industry, the QPCX-1553 Bus Monitor provides unparalleled error detection and 100% monitoring of fully loaded buses.

The Abaco Systems MIL-STD-1553 product line is significantly enhanced to meet the varying requirements of end users. The internal MIL-STD-1553 Local Processing Unit (LPU) has undergone a major update to improve and expand performance, functionality and modularity. 

The LPU version is 4.XX or 5.XX (V4/V5) on legacy firmware and version 6.XX (V6) on the new enhanced firmware. In addition to these LPU improvements, multiple other changes were added to enhance firmware and software modularity across multiple platforms.

V6 firmware is highly recommended for all new developments. Previous V4/V5 firmware has been deprecated and will no longer be actively developed but will continue to be supported.  Any future 1553 product features or enhancements will only be developed for the V6 firmware.

Using V6 firmware will require updating to BusTools/1553-API version 8.x or later.
