Overview

The portable data acquisition system form Dexcel is a very small from factor CPU with a PCI based data capture card. The PCI card can be customized as per user needs or any user board can be plugged on to the PCI card for data capture. The PCI card supports both data capture and data playback. The captured data is stored on the hard disks. The complete unit can work from the internal battery. The unit is controlled with the hand held/ desktop USB LCD.

Functionality

The portable data acquisition system supports all the standard features of a low power PC with built in UPS. The data capture/ play back function is implemented in an add-on PCI card. The PCI card supports 33MHz, 32-bit PCI with DMA. The PCI card includes a FPGA for custom logic implementation, two FIFOs and board-to-board connectors for user board.

The user can plug in his board on to this PCI card for data capture or playback.

The unit supports two 500GB hard disks for data storage. The on board CF card can be used for loading the OS/software. The LAN interface can be used to interact with the system and to transfer the data from the system.

The user can interact with the unit using the USB LCD. The USB LCD displays the status information and takes in commands through the push buttons.
