multiplexed mode
an SCXI operating mode in which analog input channels are multiplexed
into one module output so that your cabled DAQ device has access to the
module’s multiplexed output as well as the outputs on all other multiplexed
modules in the chassis through the SCXI bus. Also called serial mode.

mux
multiplexer—a switching device with multiple inputs that sequentially
connects each of its inputs to its output, typically at high speeds, in order
to measure several signals with a single analog input channel

nonlatched digital I/O
a type of digital acquisition/generation where LabVIEW updates the digital
lines or port states immediately or returns the digital value of an input line.
Also called immediate digital I/O or non-handshaking.
