To wire your module follow these steps.
1. At each end of the cable, strip some casing to expose the individual wires.
2. Trim the signal wires to 2-inch (5 cm) lengths. Strip about 3/16 inch (5 mm) of
insulation away to expose the end of the wire.
Be careful when stripping wires. Wire fragments that fall into a module
could cause damage at power up.
3. At one end of the cable, twist the drain wire and foil shield together, bend them away
from the cable, and apply shrink wrap. Then earth ground at the preferred location
based on the type of sensor you are using. See Grounding for more details.
4. At the other end of the cable, cut the drain wire and foil shield back to the cable and
apply shrink wrap.
5. Connect the signal wires to the terminal block. Connect the other end of the cable to
the analog output device.
6. Repeat steps 1 through 5 for each channel on the module.
