Power and I/O

This chapter provides information about the NI Smart Camera

POWER-I/O connector, connecting isolated inputs and isolated outputs,

and connecting to serial devices and to quadrature encoders.

POWER-I/O Connector

The POWER-I/O connector provides signal connections for power and I/O,

including isolated inputs and outputs, quadrature encoders, and serial

devices. The POWER-I/O connector is a standard female high-density

15-pin D-SUB connector. Table2-1 shows the pin organization for the

POWER-I/O connector. The two pins used to connect to a power supply,

pin 15 and pin5, are also shown in the tabl e. Refer to Getting Started with

the NI17xx Smart Camera for info rmation about connecting a power

supply to the NI Smart Camera.

Table2-1 lists the signal names and pin numbers for t he 15-pin

POWER-I/O connector. The table also lists the wire colors for the 15-pin

D-SUB pigtail cable (part number 197818-05), sold separately by National

Instruments. Cables sold by other manufacturers could have different wire

colors.
