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.
