Voltage level of digital output generated by DAQ card

[jerryguo]

Can anybody tell me how to set the voltage level of digital output generated by DAQ PCIe-6259? The default value for digital "1" is 5V, however I would like to have 3.3V, is there any easy way to do this? I'm using Labview signal express 2.0.
Thanks in advance!!!

Unfortunately, the digital output level can't be changed to 3.3V on this card. 2 solutions :

- add another DAQ card with 3.3V or programmable digital output levels
- use an external IC to adapt the level
