National Instruments NI 781xR

Connecting I/O Signals

This appendix describes how to make input and output signal connections

to the NI 781xR I/O connectors.

The NI78 1xR has four DIO connectors with 40 DIO lines per connector.

Figure B-1 shows the I/O connector locations for the NI781xR. The I/O

connectors are numbered starting at zero.
