For detailed information about digital I/O functionality and recommended

use cases, refer to Chapter4, Digital I/O Fu nctionality.

Note Isolated inputs are compatible with 5 V logic if the external circuit meets the voltage

and current requirements listed in AppendixB, Specifications.

Figure 3-8. 44-Pin DSUB Connector

Table lists pin numbers, signal names, and signal descriptions for the

44-pin connector on the NI 1450 and the 37-pin terminal block.

Caution Do not draw more than 500 mA combined from the Viso pins on the 44-pin

DSUB connector. Do not draw more than 100 mA from each isolated output.
