The Q104-1553 and Q104P-1553 boards provide new levels of performance and flexibility for MIL-STD-1553A/B Notice II in the PC/104 (ISA backplane) and PC/104-Plus (PCI backplane) form factors.

Available in commercial and extended temperature range, ruggedized versions with one, two or four dual-redundant channels, the Q104-1553 includes advanced API (Application Programming Interface) software that reduces application development time. Standard features include 1 Mbyte of RAM per channel, 64-bit, 25 nanosecond message timetagging, triggers, extensive BC & RT link-list structures, error detection/injection, transformer coupling, automatic/manual RT Status Bit and Mode Code responses, programmable or hardwired RT Address lines (with 1760 startup time and busy bit set), along with advanced BC functionality.

The Abaco Systems Q104P-1553 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.
