Difficulties in initializing PCI6527

[cgao]

I am trying to setup a PCI627 card with LabView program. After setting up, I couldn't get any voltage outputs by running some very simple single channel output. I ran LabView samplers and still no response. In addition, I measure the voltage on pin 49 and 99 ( supposed to be +5V according to the manual), and still could not get voltage readings.

Could anyone give me some suggestions/comments on how to get digital output from a PCI6527 ? What the voltage output should be (5V?, 60V?)? Is that adjustable?

Thank you very much!

You can use the Measurement & Automation Explorer (MAX) to test the output channels of the card;
there ist also a link to the pin assignment

Hi,

As mentionned in the above answer, the best way to test the board's outputs is by using MAX, there you can easi~ly switch on and off all outputs of the board.
But that's not the main reason why you're not having output from it. This board has switching outputs, meaning that what you do is closing the connection between the two pins of each output. So, for instance, if you close DO 0.0, you will connect pin 47 and 48. So, you need to connect a signal to pin 47 and when the DO 0.0 if high, you will have that voltage on pin 48. And this answers the question of how much is the high level voltage? It is how much you connect to the high pin of the output untill 60 V that's the maximum isolation it accepts.
About the 5V on pin 49 and 99 that's very strange... you should have 5 V between pin 49, 99 and 50, 100.

Hope this helps,
Paulo

Thanks to TimoS and PauloM for your reply. I do appreciate your help.
I will try to use MAX for testing.
regarding the 5V measurement, I connected the 49 and 50 pins to a mutlimeter to see the voltage reading, am I right?

thank you!

Yes,

There should be 5V there, otherwise something is wrong.
