First of all, please refer to
R Series Help to make sure whether the digital logic levels can be changed on your R series boards. You can follow the following steps to adjust logic levels on the PXIe or PCIe R series Board.
1. In LabVIEW project, right-click on the
FPGA Target and select
Change I/O Configuration... to open the
Configure R Series I/O dialog box.
2. In the
Configure R Series I/O dialog box, select the
Digital Connectors that you would like to change the logic levels for. Use the
Shift and
Ctrl keys to select multiple channels at once.
3. Select the logic level you would like to use from the
Logic Family pull-down menu.
4. Click
OK.
Additional Information
FPGA PXIe R Series cards do not support programmatically changing the logic family with the FPGA property nodes.
