reading/writing digital lines without external hardware (besides daq device)

[Chapashop]

Hi,

I have a USB-6259 (mass termination).  I don't have any additional hardware, just the USB device.  I  am trying to use the MAX utility (4.2.1) with NIDAQmx (8.5).  I eventually want to program digital lines (read and write them) using the NIDAQmx API.  I ran some of the VB6 samples.  I thought how it works is that I could run the WriteDigChan VB code to set line(s) on or off, then use the ReadDigChan VB code to read those lines I changed.  However that did not work so I started created some tasks using MAX however that does not work either.  I hope this is not too stupid a question but I am not too familiar with the hardware.  Do I need some additional hardware connected to my 6259 to keep those digital lines in one state or another?

thanks, David

You don't need any additional hardware.

I don't know how to use the device with VB however.

Without regard to using it in VB, I am trying to understand the operation in MAX.  I am attaching two screenshots of 2 tasks that I am using.

thanks for replying, David
