Preparing to Wire Signals
Keep the following recommendations in mind when wiring signals to
a KUSB-3160 module:
• Use individually shielded twisted-pair wire (size 14 to 26 AWG)
when using the KUSB-3160 module 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 KUSB-3160 module 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 KUSB-3160
module is operational.
• When first installing the module, try wiring the signals as
follows:
−
Wire a digital input to digital input line 0 of bank 11.
−
Wire a digital output to digital output line 0 of bank 5.
−
Then, run the Quick Data Acq application (described in
Chapter 5 starting on page 39 ) to verify that the module is
operating properly.
Once you have determined that the module is operating
properly, wire the signals according to your application’s
requirements.
CAUTION:
To avoid electrostatic sensitivity, it is recommended that you unplug
your KUSB-3160 module from the computer before wiring signals.
