NI 6143 Specifications

This document lists the I/O terminal summary and specifications for the NI PCI/PXI-6143.

For the most current edition of this document, refer to ni.com/manuals. Refer to the DAQ Quick Start Guide for more information about accessing documents on the NI-DAQ CD.

 Note With NI-DAQmx, National Instruments has revised its terminal names so they are easier to understand and more consistent among NI hardware and software products. The revised terminal names used in this document are usually similar to the names they replace. For a complete list of Traditional NI-DAQ terminal names and their NI-DAQmx equivalents, refer to the Terminal Name Equivalents table in the S Series Help.
