A traditional PXI system typically comprises a rack full of small low channel count cards and a Pentium based System Slot Controller. While D-TACQ ACQ196CPCI and ACQ216CPCI cards can work just fine in this scenario, the onboard intelligence and integrated logic enables other configurations, frequently with improved cost effectiveness and size:
Standalone Ethernet ApplianceACQ216CPCI
are able to act independently of the Compact PCI backplane, with control and data upload taking place over the integrated Ethernet. The cards can be dropped into an existing system, and make use of existing backplane reset, clock and PXI
signaling, without any requirements for a driver on the system slot card at all. System integration is a matter of familiar, high scaleable Ethernet networking. In fact, a system slot card is no longer needed to operate a system with ACQ2xx cards. Combined with the high channel density, this enables highly compact, cost-effective applications.
System Slot Capability
ACQ216CPCI is able to act as a system slot controller, and provide clock, reset and PXI
compatible signals to other ACQ196CPCI/ACQ216CPCI cards in the rack.
ACQ196CPCI takes this further - we have successfully deployed ACQ196CPCI in the system slot, with third party cards in other slots, and controlled these cards using the standard Linux device driver, cross compiled for the ARM processor. Tested use cases include:
Ability to host peripheral cards means that, provided an Open Source Linux device driver is available, in principle ACQ196CPCI can be used in a small compact system in conjunction with any of hundreds of network, control and storage functions accessible via PMC and CPCI modules.
