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. Table 2-1 shows the pin organization for
the POWER-I/O connector. The two pins used to connect to a power supply, pin 15 and pin 5,
are also shown in the table. Refer to
Getting Started with the NI 17xx Smart Camera
for
information about connecting a power supply to the NI Smart Camera.
Table 2-1 lists the signal names and pin numbers for the 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.
