Delphi support pci1200 card

Question

Hi,
for a particular project I'm working on, I'm using a National
Instruments LAB-PC-1200AI card. The thing is, I have to be using Delphi as a
programing language rather than LabView which makes things rather tricky.
in the support examples given along , there is an delphi application that turns on the leds and turns them off , but this only runs for 5 minutes , i need to make it run for a longer time , after 5 minutes the message flashes that contact ni about the code . is there a way i can access the i/0 lines of the daq using delphi , if so is there some documentation about the libraries and procedures and stuff , and where could i get the pdf documents for that .i wont be using labview and only delphi so need to work with it only

Answer 1

this is the unit for E-series working with NIdaq7.01 and maybe 6.9.x
