Note

For safety purposes and to prevent damage to equipment when high voltages are present, all

NI SC Express modules and terminal blocks are keyed to prevent connection between incompatible
terminal blocks, modules, and/or cables.

Power on the chassis if it is powered off.

Figure 6 shows an example NI SC Express system setup.

Step 5. Confirm NI SC Express Module Recognition

To confirm module recognition, complete the following steps:

Note

Make sure you are using the most recent version of NI-DAQmx. If you are using an older

version of the driver software, the NI SC Express terminal block may work only in basic functionality
mode. Unsupported terminal blocks appear in Measurement & Automation Explorer (MAX) with an
X next to them.

1.

Launch MAX.

2.

Expand

Devices and Interfaces»NI-DAQmx Devices

to confirm that MAX detects the module

and terminal block. The terminal block should appear beneath its associated module. If your
module or terminal block is not listed, press <F5> to refresh MAX. If the module is still not
recognized, go to
