Screw Terminals
The SCC-68 provides screw terminals for easy I/O connectivity.
Device Pinouts
For a list of pins and their corresponding signal assignments, refer to the
quick reference guide for the device, which can be found in the
Quick
Reference Guides
section of this document. Refer to the DAQ device
documentation for additional details about the DAQ device signals.
Wiring to Screw Terminals
To connect signals to the SCC-68, complete the following steps while
referring to Figure 1.
1.
Disconnect the 68-pin cable from the SCC-68.
2.
Remove the top cover as directed in the
Opening the Enclosure
section.
3.
Slide the signal wires through the wire entry strain-relief opening. For
more information about using strain relief with the SCC-68, refer to
the
Integrated Strain Relief
section.
4.
Connect the wires to the screw terminals by stripping off 7 mm
(0.28 in.) of the insulation, inserting the conductors into the terminals,
and tightening the screws.
5.
Close the top cover.
You can now connect the SCC-68 to the 68-pin I/O connector.
Integrated Strain Relief
Strain relief for the I/O connector wires is provided through a
labyrinth-style wire entry at the front of the SCC-68 device. For larger
gauge connector wires and jacketed cables, bundle the wires together and
secure the wires to the holes in the wire entry opening using the provided
cable ties.
For smaller gauge connector wires (26 AWG–30 AWG), thread the wires
through the strain-relief posts located on the side opposite the wire entry.
By lacing the connector wires through these posts, movement is limited.
Note
Route all SCC signals through the left wire-entry side of the SCC-68. Route all other
signals through the right wire-entry side.
