Connecting Digital I/O Signals
The DIO signals on the NI 6013/6014 are DIO<0..7> and DGND.
DIO<0..7> are the signals making up the DIO port, and DGND is the
ground-reference signal for the DIO port. You can program all lines
individually to be inputs or outputs.

Caution
Exceeding the maximum input voltage ratings, which are listed in Table 4-3, can
damage the NI 6013/6014 and the computer. NI is not liable for any damage resulting from
such signal connections.
