Getting Started with the cDAQ Controller
Complete the following steps to connect a power source to the cDAQ controller.
1.
Make sure the power source is turned off.
2.
Install the ferrite (National Instruments part number 711849-01, included in the shipping
kit) across the negative and positive leads of the power source, approximately 50 to 75 mm
(2 to 3 in.) from the ends of the leads near the cDAQ controller, as shown in Figure 1-6.

from the cDAQ controller. Figure 1-7 shows the terminal screws, which secure the wires in
the screw terminals, and the connector screw flanges, which secure the connector plug on
the front panel.
