how to configure other digital ports except port 0 of daq 6351 for acquiring digital waveform

[sathi]

sir,

i can acquire digital waveform using 8 line of port 0.but i have to get 24 bit digital waveform.So please tell me how can I configure other DIO ports so that i acquired digital waveform using those DIO line also

You should be able to create a DAQmx task to read Port0, Port1, and Port2.  When you read the data from DAQmx, you will then have to combine the array of port data as needed.

Keep in mind that the 6351 only has 8 hardware timed lines. Port 1 and Port 2 can only be read using software timing.

Thanks for reply....can I triggered port 2 and port 1 using external clock signal...??Other thing is that,in X series Daq manual(page-121),it is written that other DIO inputs can be configured for waveform acquision,How is that possible???

please reply.its urgent

Page 121 (6-5) says "You can acquire digital waveforms on the Port 0 DIO lines." I have no idea what you are referring to.

Based on Steven K's response, I would say no.  Ports 1 and 2 are only software triggerable which means that they only read when a program requests data from them.

Sir I want to refer following line...

"

You can configure each DIO line to be an output, a static input, or a digital
waveform acquisition input."

Here it is mentioned that I can configure each DIO line to be Digital waveform acquisition..How can I do this???

Thanks for your reply...

will u please give a block diagram of what you said..then it will really helpful to me.
