Each DAP (Data Acquisition Processor) system starts with a data acquisition hardware board and adds signal interface boards to form a channel architecture.
Several DAP boards – in any combination of model numbers – can work together as a single, synchronized, PC-based system [1]. Some simple DAP systems will have only a handful of inputs and outputs; others may have maybe a hundred or so. A multi-DAP system potentially may have several thousand analog and digital inputs and outputs. Whatever the case, the signals have to connect somewhere. The examples here illustrate the channel architecture used by Microstar Laboratories: signal connectors on 3U (100mm high) Eurocard B [2] (220mm deep) boards – Eurocards – that often pre-process a signal.
All Microstar Laboratories Eurocards – other than DAP-to-backplane interfaces – offer one or more types of termination. Most also multiplex inputs or outputs. Many perform additional functions. Browse the full range, arranged in the eight main function groups.
- simple termination
- simple multiplexing
- anti-alias filtering
- simultaneous sampling
- isolation
- counter/timer
- quadrature-decoder
- signal conditioning
The need for one or more of the listed functions, the number and speed of inputs and outputs, the mix of analog and digital signals, and termination choices – as well as the extent that your application can benefit from onboard processing – determines the DAP board, Microstar Laboratories Eurocards, and enclosure models required. To understand the part number suffixes for our Eurocard boards, take a look at the explanatory table. Or contact us. Account Representatives and Application Engineers at Microstar Laboratories know the product range, know how it works in a number of applications, and they welcome the opportunity to talk with you about how it can work in yours.
Feel free to look around more on your own. [3] Whether you do that first or not, do please talk with us about your application. Between us we can confirm a suitable channel architecture and overall signal configuration, illustrated by a 3-D line drawing, like the samples you see here. You will clearly see the products you need and the ways they connect. We do not charge for this service, so go ahead and call and talk to us today.

[1] On one PC or several networked PCs. DAPcell Local Server and DAPcell Network Server software allow a number of DAP boards to act as a single synchronized system even though spread across networked PCs.
[2] The Eurocard A format, used in CompactPCI systems, has the same 3U height (100mm) but not the depth: 160mm against 220mm for the Eurocard B format.
