Problem with DAQMX digital output

[V.GRAF]

I work on a DAQ 6025E and all the exemples for digital output with DAQMX don't fonction. Is this card fonction with DAQMX?

Are you using the daqmx functions? If so please post the code. Or you can try using the Daq assistant. This will step you through the process of configuring a digital output. hope this helps.

Yes, the 6035 is supported (unless you're running win 95... or 3.1... you are on windows, right?)

Hi V.GRAF,

The DAQ 6025E is a special card in terms of digital I/O. This is because it has two different semiconductor chips handling the digital. It has the DAQ-STC chip handling the first port of 8 bits (Port 0). It then has the 8255 chip handling the 3 other ports.

In general, you should be able to use any of the DAQmx programs for digital with this card. However, you have to make sure that you are configuring the entire port at the beginning of your program. This is because if you reconfigure any of the 3 ports on the 8255 PPI chip, it will reset the port. So my suggestion is to not use "line" configuring but instead use "port" configuring.

Here are a couple Knowledge Bases that discuss the issue.

kindly reply plzz

thank you....
