2. Attach the quick reference label to the inside of the top cover as shown in
Figure 1. You can find quick reference labels, which specify accessory pinout
information for many compatible devices, by going to
3. Configure switches for the signal types you are using, as explained in
the SCB-68 in Direct Feedthrough Mode
4. Adjust the strain-relief hardware by loosening the strain-relief screws with a
Phillips #2 screwdriver and sliding the signal wires through the front panel
strain-relief opening. If you are connecting multiple signals, remove the top
strain-relief bar and add insulation or padding if necessary.
5. Connect the wires to the screw terminals by stripping 6.35 mm (0.25 in.) of
insulation, inserting the wires into the screw terminals, and securely
tightening the screws with the flathead screwdriver to a torque of
0.5–0.6 N · m(4.43–5.31 lb · in.).
6. Reinstall the strain-relief (if removed) and tighten the strain-relief screws.
7. Close the top cover and reinsert the shielding screws to ensure proper
shielding.
Caution
Do not connect input voltages ≥42 V pk/60 V DC to the
SCB-68. The SCB-68 is not designed for any input voltages ≥42 V pk/
60 V DC, even if a user-installed voltage divider reduces the voltage
to within the input range of the DAQ device. Input voltages ≥42 V pk/
60 V DC can damage the SCB-68, all devices connected to it, and the
host computer.
8. Connect the SCB-68(s) to the DAQ device using the appropriate cable(s) for
your device. For a complete list of cabling options for supported devices, visit
9. Launch Measurement & Automation Explorer (NI MAX), confirm that your DAQ
device is recognized, and configure your device settings. Refer to the DAQ
Getting Started Guide for more information.
10. (Optional) If you are going to take measurements with an MIO DAQ device,
configure the SCB-68 as an accessory for a DAQ device using MAX by
completing the following steps.
