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.

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.
