Bustec was founded in 1997, in Ireland by Dr. Fred Bloennigen, current CEO.

[2][3] It also introduced the first to market VXI 4.0 Slot-0 controller, with a hot-pluggable PCIe x4 connection to host server.

Most notable include: Agusta Westland's helicopter wind tunnel testing,[6][7][8] Honeywell's testing of computers for the International Space Station, VXI Slot-0 modules for Rohde & Schwarz, Atos Origin's monitoring of Nuclear Power plants in France and Lockheed Martin's eCASS system for the United States Navy.

This approach is a flexible solution, because the modules can be configured to meet system specific needs, allowing better space utilization.

Up to 8 such function cards can be mounted on a single VXI size C motherboard and up to 4 of them in the 1U, half-width LXI carrier.
