†
This document refers to the ports as A, B, and C and the PPIs (82C55As) as A, B, C, and D. NI-DAQmx, Traditional
NI-DAQ (Legacy), and LabVIEW documentation use numbers to identify each port and PPI. For example, this manual uses
PPI A port A to refer to port A of the 82C55A identified as PPI A. NI-DAQmx, Traditional NI-DAQ (Legacy),
LabWindows/CVI, LabVIEW, or other application software documentation, however, refer to this port as 0. The Alternate
Port ID column shows the correlation between the different port names.
