ProDAQ 3026 Provides a High Throughput and Low Latency Solution to Replace Legacy VXI Interfaces

Bustec announced today the ProDAQ 3026, a single-slot, C-size, VXIbus slot-0 to PCI Express interface. With low latency and up to 40 MB/s throughput, the ProDAQ 3026 provides a low-cost solution for replacing legacy VXI interfaces. The new interface enables arbitrary power on/off order of host PC and chassis, is optimized for low first-word latency, and is available with interfaces for PCI- and PCI Express-based computers.

“The ProDAQ 3026 is a low-cost PCIe VXI Slot-0 interface for applications that do not require the 320 MB/s throughput or optional LXI triggering of the ProDAQ 3030,” said Fred Bloennigen, CEO of Bustec. “This new VXI Controller delivers flexibility alongside market-leading throughput and latency performance, showing Bustec’s continued investment to innovating on the VXI platform. Our line of products allows our mil/aero customers to reliably sustain their test systems, as well as design new high-performance VXI and hybrid systems.”

The ProDAQ 3026 supports PCI Express hot-plug functionality, allowing engineers to power up a host PC simultaneously or independently from any and all VXI chassis. Unlike other interfaces that require engineers to power down a host PC before turning off a VXI chassis, the ProDAQ 3026 allows engineers to power off any VXI chassis to interchange instruments without having to shut down the host PC, ultimately saving time.

Up to two ProDAQ 3026 interfaces can be connected directly to the ProDAQ 3261 PCI Express host interface card, which fits into a standard PCI Express x4 slot in a desktop or server computer. For a desktop or server computer with PCI bus slots only, the ProDAQ 3262 provides a PCI-to-PCI Express bridge in addition to the PCI Express cable interface. It fits into a standard PCI slot and also allows up to two ProDAQ 3026 to be connected.

Bustec Family of VXIbus Slot-0 Interfaces and Controllers offers a Range of Capabilities
As a leading manufacturer of VXI slot-0s and data acquisition instrumentation, Bustec played a key role in driving the VXI-1 Revision 4.0 standard. The first VXI controller to support the new VXI-1 Rev. 4.0 standard, the ProDAQ 3000 Series ProDAQ 3030 interface, fully supports 2eSST transfers, delivering up to 320 MB/s of throughput and latency of less than 500 nsec for single word transfers.

Earlier this year, Lockheed Martin selected the BustecProDAQ 3030 VXI slot-0 interface for its new electronic Consolidated Automated Support System (eCASS). With the ProDAQ VXI interface, Lockheed Martin can deliver a test system capable of testing modern aircraft electronics, achieving LXI triggering, reducing test time, and maintaining compatibility with existing hardware and software of the previous-generation system.
