NI SCB-68 HSDIO Connection Guide & Specifications

5.

Prepare the shielded, multi-conductor cable by stripping the insulation and shield(s) to 
expose enough signal wire to connect from just inside the strain-relief bar to the appropriate 
screw terminal. Ensure that the shield drain wire(s) of the shielded cable is long enough to 
connect to one of the two ground lugs on the circuit board, which are shown in Figure 2.

6.

Connect the wires of the shielded, multi-conductor cable to the screw terminals by stripping 
6 mm (0.25 in.) of insulation, inserting the wires into the screw terminals, and securely 
tightening the screws with a flathead screwdriver to a torque of 0.5-0.6 N · m (4-5 in. · lb).

Note

Refer to the 

Special Considerations for HSDIO Connections

 section for 

information about appropriate cables and signal termination.

Caution

To ensure the specified EMC performance, signal wires routed outside of 

the enclosure must be contained within a shielded cable and connected to shielded 
accessories.

7.

Reinstall the strain-relief bar (if removed) and tighten the strain-relief screws. If the 
shielded cable is too large to route through the strain-relief hardware, either use multiple, 
smaller-diameter cables or remove the top strain-relief bar and add insulation or padding if 
necessary to constrain the cable.

8.

Replace the cover.

Caution

You must install the cover before use.

9.

Connect the NI SCB-68 HSDIO to the RIO device using the appropriate cable(s) for the 
device.

10. Launch Measurement & Automation Explorer (MAX). In the left panel, expand 

Devices and Interfaces

 to confirm that the DAQ device is recognized, and then configure 

device settings.

Mounting the NI SCB-68 HSDIO on a DIN Rail

You can use the NI SCB-68 HSDIO on a desktop or mount it on a standard DIN rail.

The NI 9913 DIN rail mounting kit (part number 783198-01) contains one clip for mounting the 
NI SCB-68 HSDIO on a standard 35 mm DIN rail. Fasten the DIN rail clip to the enclosure using 
the two flathead #6-32 × 1/4” screws included in the kit with a #2 Phillips screwdriver, as shown 
in Figure 3.

Note

Do not use the threaded holes on the NI SCB-68 HSDIO for DIN rail 

mounting more than five times. Unscrewing and reinstalling the DIN rail clip might 
compromise the connection between the DIN rail clip and enclosure.
