The externalreference signal can be either a DC or an AC signal. The
devicemultiplies thi s reference signal by the DACcode (divided by
the full-scale DACcode) to generate the output voltage.
Digital I/O Signal Connections
The digitalI/O signals are DIO<0..7> and DGND. DIO<0..7> are the
signalsmaking 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.The AT-MIO-16DE-10 has 24 additional DIO lines, configured as
three8 -bit ports: PA<0..7>, PB<0..7>, and PC<0..7>. You can configure
each portfor bothinput and output in various combinations, with some
handshaking capabilities.
Caution Exceeding themaximum input voltage ratings, which are listed in Tables 4-3
through 4-6, can damage the ATE Series device and the PC. NI is not liable for any
damage resulting from such signal connections.
