NI Vision I/O Terminal Block and Prototyping Accessory

Use the NI Vision I/O Terminal Block and Prototyping Accessory to
troubleshoot and prototype digital I/O applications for the NI 8254R, the
NI 8255R, and the NI CVS-1450 Series compact vision system. The
NI Vision I/O Terminal Block and Prototyping Accessory provides screw
terminals for easy connections and LEDs for each signal.
Note TRIG 0, TRIG 1, and TRIG 2 signals are not accessible through the standard 44 to
37-pin cable and NI Vision I/O Terminal Block and Prototyping Accessory.

Power Requirements

This section describes the power requirements of the NI 8254R.

Isolated Outputs Power Connector

Figure 3-3 illustrates the isolated outputs power connector on the
NI 8254R.
The isolated outputs power connector on the NI 8254R accommodates one
power supply. The V terminal provides the isolated output circuitry (5 to
30 VDC) for the NI 8254R. The C terminal provides the common-mode
signal for the NI 8254R, as shown in Table.
