D-TACQ digitizers conform to recognized industrial standards, and are designed to work in standard chassis. In common with most other digitizer cards, they can work as peripheral devices under the control of a system master computer in the chassis.
In addition, D-TACQ's 2G cards are self contained, networked Linux computers in their own right, and so they are capable of running directly off a network, without the need for a system master. This can lead to considerable simplification by eliminating backplane resource conflicts, and, by using TCP/IP networking, in some cases eliminating the need for a driver altogether.
The standalone device is an effective solution both in small applications - because there is no overhead of a system slot card, and in large applications, because of the inherent scaleability of networked devices.
Finally, 2G cards may themselves act as system masters, potentially controlling other cards via the pci backplane on the chassis.
