Can't send DIO signals from DAQ toolbox to NI board

[EfrenReyes]

Hello,I am trying to send digital
outputs with Matlab DAQ toolbox to a NI PCI-6224 card (and through a NI
SCB-68 connector block to a Plexon recording rig), but am having
trouble getting the signals to the connector block.I'm using
Matlab R2007a, DAQ toolbox version 2.10, the NI-DAQmx 8.6.1 driver, and
the correct adaptors ('nidaq', 'parallel', and 'winsound') are working.
Furthermore, I know that the card and connector block are working
because someone else is accessing it with LabVIEW for a totally
different task.I know the board ID is 'Dev1', and when I run
the following code, I don't get any error messages. Again, however, I
can't get it to write signals to the connector block (or measure them
using NI Measurement and Automation Explorer). >>dio = digitalio('nidaq','Dev1');addline(dio,0:7,'out');pval = [1 1 1 1 0 1 0 1];putvalue(dio,pval)gval = getvalue(dio);delete(dio)clear dioI'm not sure where to go from here. Any suggestions would be very much appreciated.Thanks.

Hi,



I found <a href="http://www.mathworks.com/products/daq/supportedio14005.html" target="_blank">this</a>
link that says that you need atleast version 2.8 of the toolbox for it
to work with the PCI-6224.&nbsp; I think that might be the problem.&nbsp; Have you got any other functionality to work on this board using the current version that you have?&nbsp; Could you please upgrade to that version
and see if that helps.

It looks like you're doing everything correctly.&nbsp; Does it work when you do it from MAX? -Rob
