DDC's new BUS-65536 VXIbus board claims many benefits to engineers and technicians developing and commissioning Mil-Std-1553 data bus systems (Plate 1). The versatile C-size 16-bit printed circuit card is designed for testing and simulation of bus controllers and multiple remote terminals.

MIL-Std-1553 is the West's standard military aircraft data bus and operates using a dual redundant two-wire system. Each of the buses takes a different route around the aircraft, such that if one is damaged, the other can handle the full workload. All of the avionic equipment is provided with a common Mil-Std-1553 data bus interface which enables equipment interchangability and rapid servicing.
The BUS-65536 provides full intelligent interfacing between the Mil-Std-1553 data bus and a VXI bus, allowing it to simulate simultaneously a bus controller, multiple remote terminals and an intelligent bus monitor. With the board, engineers can save considerable time testing, developing and simulating these systems.
Using the system, errors can be injected into the bus controller messages and any of the emulated remote terminal responses. At the present time, the BU-65536 supports Hewlett Packard's HP7500 software package Series C with V743 controller and HP VTL 3.0 library for HP-UX 10.01.
Real-time libraries (RTLs) allow the user to control the BUS-65536, directly.
Other features include double buffered data tables, programmable interrupts, extensive error injection, real-time access to the monitor stack, multiple card support, and the ability to emulate up to 31 remote terminals that meet both Mil-Std-l553A and B response times.
The BUS-65536 will also soon include support for National Instrument's PC-based MXI interface running under Windows 95 or Windows NT. The user-friendly, menu-driven software will allow the user to become fully operational in a matter of minutes without extensive programming or Mil-Std-1553 experience.
