15-pin D-SUB Connector

The 15-pin D-SUB connector connects to general purpose digital I/O. The

general purpose digital I/O available on this connector includes four TTL

I/O lines, two optically isolated input lines, and two RS-422 input lines.

National Instruments provides a generic 15-pin cable assembly kit

(part number 190912-04) that breaks the connector out into 15 color-coded

wires for easy connectivity. Refer to the 15-Pin D-SUB Cable

Specifications section of Appendix A, Cabling, for information about

ordering a cable assembly kit.

If you require twisted pair wiring, you must build a custom cable. Refer to

the connector pin assignments in Figure 3-3 and the 15-Pin D-SUB Cable

Specifications section of Appendix A, Cabling, to build a custom cable for

the 15-pin D-SUB connector.
