Digital Reader
The NI ELVISmx Digital Reader reads digital data from the NI myDAQ digital lines.
NI ELVISmx Digital Reader groups the I/O lines into ports through which data can be read. You
can read one port at a time, either continuously or as a single reading. The lines are grouped into
two ports of four pins (0 to 3 and 4 to 7) or one port of eight pins (0 to 7).
