Preparing to Wire Signals
This section provides recommendations and information about
wiring signals to the KUSB-3116 module.
Wiring Recommendations
Keep the following recommendations in mind when wiring signals to
a BNC connection box:
• Use individually shielded twisted-pair wire (size 14 to 26 AWG)
in highly noisy electrical environments.
• Separate power and signal lines by using physically different
wiring paths or conduits.
• To avoid noise, do not locate the box and cabling next to sources
that produce high electromagnetic fields, such as large electric
motors, power lines, solenoids, and electric arcs, unless the
signals are enclosed in a mumetal shield.
• Prevent electrostatic discharge to the I/O while the box is
operational.
• Connect all unused analog input channels to analog ground.
CAUTION:
To avoid electrostatic sensitivity, it is recommended that you unplug
your KUSB-3116 module from the computer before wiring signals.
