USB-7855R DIO outputs different waveform from the inputted waveform

[dragon1]

Hello.

I am using usb-7855r.

I am outputing the exact waveform that I inputted in usb-7855r. however i m not getting the same waveform. The frequency is the same but the voltage level is different. I am suspecting the logic level of the device. 

From the user manual or specification of the device, it seems that I can change the logic family but I don't know how.

Does anyone know how to change logic level for this device?

I've never used that card before - but in your project, if you right click on the device or IO item and select properties - is there a panel in there that allows you to configure the logic family?

Hey buddy,

You  want to right click on FPGA Target and click on Change I/O Configuration...

Then you can set the logic levels.

More details in the Help, and in this Tutorial:

foxhound73 thank you!

I can select different logic levels!
