Can anyone tell me what´s wrong with this Timing DAQmx VI configuration???

Hi all.
I´m using a PCI 6025E with Labview 7.1, and everytime I try to run this VI, it returns this error message:
 
Error -200077 occurred at Property Node DAQmx Timing (arg 1) in DAQmx Timing (Sample Clock).vi->Digital Out Write Dig Chan.vi
 
It also says that I have selected SAMPLE CLOCK (wich I did), but instead I should select ON DEMAND or HANDSHAKE modes.
I´m not even able to find ON DEMAND mode on the list.
 
I´m still a beginner on DAQmx, and I´m sure that this is the result of any mistake, but where or what?
 
I´ll apretiate any help.
 
Thanks

Hi

open the daqmx timing vi ( double click on it) and go to its block diagram. you will see a property node.

now, you can see sample clock. click on it and you can choose on demand. Probably, you will have to change more things to get your up and program running, so do not forget to save a copy of daqmx timing to work with and keep the one from the library as is.

Also, a goo idea is  looking  for daq examples in this web. Most of the time, you will find some that can help you.

hope it helps

Hi again.
Many thanks for you guys.
I will keep you informed as soon I try any of your ideias.
And by the way:
Can anyone tell me where I can find a good and consistent tutorial about DAQmx?
Until now, I was just able to find some lose bits spreaded on NI´s website.
 
Best regards
