The NI SMB-2163 provides connectivity to up to 32 single-ended DIO
channels, three programmable function interface (PFI) channels, and
two clock channels of an NI digital waveform generator/analyzer. You
can connect to these signals from the labeled SMB connectors on the
NI SMB-2163.
Caution Connections that exceed any of the maximum ratings for the NI SMB-2163
or the NI digital waveform generator/analyzer can damage the device and the computer.
Maximum input ratings are provided in the specifications document that shipped with the
NI digital waveform generator/analyzer. NI is not liable for any damages resulting from
such signal connections.
