Info reqd for NI 6052E Card

Myslef is Murtuza Talwari. I m workin in iasys Technologies,Pune,Inida. We are
developing the SCADA software for automobile and power industries. In our one SCADA
packages we are using the NI-PCI-6052E card for the data acquisition purpose. We
developed our software in Linux 2.4.4 Kernel with RT support and for the data
acquisition from the card we are using comedi driver.

 In that when we start our application we first run the comedi_calibrate utility for
the calibration of the PCI-6052E cards so it is calibrate the card but what we want
is this utiltiy not calibrate the card but it only read the FACTORY CALDAC CONSTANTS
from the card and write it back to the CARD so we dont want to write new CALDAC
VALUES but write the FACTORY CALDAC VALUES only so is there any optiong in the
comedi_calibrate utility which dont calibrate the card but only RESET the CALDAC
values to the FACTORY CALDAC values. so pls give the information for the same.

 Waiting for positive reply. And i m also attach the output of the comedi_calibrate
utility.

Regards
Murutza Talwari
