  1. Screw Terminals
  2. 100-Pin I/O Connector
  3. PCB Mount Screw
  4. Chassis Ground Lug and PCB Mount Screw
Caution The chassis ground lug on your SCB-100A is for grounding high-impedance sources, such as a floating source (1 mA maximum) and for terminating the shields of connected cables. Do not use the chassis ground lug as a safety earth ground.

To get started with the SCB-100A, complete the following steps while referring to the previous figures. If you have not already installed your DAQ device or module, refer to the getting started guide that came with your product for instructions. Remove all cables from the SCB-100A before getting started.

  1. (Optional) Mount the SCB-100A to a panel or DIN rail, as described in the Mounting the SCB-100A section.
  2. Remove the cover.
  3. Remove the film from both sides of the cover.
  4. (Optional) Attach the quick reference label to the inside of the cover. For quick reference labels for most compatible products, go to ni.com/info and enter the Info Code scb100alabels.
    Tip You can stand the cover in the SCB-100A for easy reference.
  5. Loosen the strain-relief bar by removing the strain-relief screws with a #2 Phillips screwdriver.

  6. Connect the wires to the screw terminals by stripping off the wire insulation, inserting the wires into the screw terminals, and securely tightening the screws with the flathead screwdriver. Refer to the Specifications section for screw-terminal wiring gauge and torque information.

    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. Cable shields must be terminated to the chassis ground lug using as short a connection as is practical.
  7. Reinstall the strain-relief (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 cover prior to use.
    Caution Do not connect input voltages >30 V RMS/42 V peak/60 V DC to the SCB-100A. Input voltages >30 V RMS/42 V peak/60 V DC can damage the SCB-100A, all devices or modules connected to it, and the host computer.
  9. Connect the SCB-100A to the DAQ device or module using the SH100-100-F cable. Refer to the Specifications section for information about the SCB-100A I/O connector.
    Note To ensure the specified EMC performance, operate this product only with shielded cables.
  10. Launch Measurement & Automation Explorer (MAX). In the left panel, expand Devices and Interfaces to confirm that your DAQ device or module is recognized, and then configure your device settings.
  11. (Optional) Configure the DAQ device or module connected to the SCB-100A by completing the following steps.
    1. In MAX, right-click your DAQ device or module and select Configure.
    2. Configure the device or module properties and click OK.
  12. Test specific device functionality. Run a Test Panel in MAX by right-clicking your DAQ device or module and selecting Test Panels. Click Start to test the device or module functions.
Note When you have finished using the SCB-100A, power off any external signals connected to the SCB-100A before you power off your computer.
