SC-2345 connector block (The following does not apply to the SC-2345
with configurable connectors or to the SC-2350.)
A metallized nylon knit EMI gasket is attached to the strain-relief bars of
the SC-2345 connector block. Using shielded cables to connect the signals
allows you to ground the shielded signal cables. Stripping the insulation
away from the shield of the cables forms a chassis ground connection at the
strain-relief bar. To avoid adding noise to the signal, ground the cable shield
only at one end. For complete signal connection information, refer to the
SCC-XX module user guide. For more information about using the
SC-2345, refer to the SC-2345/2350 User Manual.
SCC modules are required for connecting to the analog inputs or analog
outputs of the DAQ device. You do not need to use SCC modules to
connect to the CTR and P0. signals of the DAQ device, which are
accessible from the SC-2345 carrier. Refer to the SC-2345/2350 Carrier
User Manual for more information.
Each SCC module has a lengthwise color stripe label on the top, as
illustrated in Figure 11, that indicates the module type and function
classification of the module and displays a corresponding icon.
