basic concept for DAQmx

[labmaster]

I am a very beginner in DAQ with LV 8.2

I would like to know the basic knowledge of DAQ programming

For example, meaning of "port" and "Dev1/port0/line0:3"

Would you please recommend some basic material which should be learned before DAQ?

Hi there,
for beginners DAQ stands for Data Acquisition. Every DAQ card will have a device identification address which is usually called as "Dev" and through that address, the DAQ can be accessed through Ports. Each port will have a set of lines. If you are measuring voltage on one of the lines, we need to give a full instruction like /Dev0/port1/line4 which will make the measurement on line4.
The best place to learn about this is online at www.ni.com and give a search for online documentation or you can also refer a manual which is what I did when I was starting....stuff is pretty obvious once you get a hang of it.

hope this helps.

thanks,
Kashyap

Together with NI-DAQ some material is installed. You can access this under Start >> Programs >> National Instruments >> NI-DAQ.

There is a quick start manual and a complete help. This is named something like "Help for DAQmx" (in German "Hilfe für DAQmx").

Added:

Dev1/port0/line0:3

Dev1 is the name of the card as it is configured in MAX. Dev1 is the default name for the first device found by the driver.

port0 is the first port of a digital I/O card or the digital I/O part of a multifunction card or other device having digital I/O.

line0:3 are the first 4 lines on this port.
