7. Click on the AIO Panel entry. The Analog I/O Panel setup screen appears.
NOTE
If more than one type of board is installed in your computer under
DriverLINX, the Analog I/O Panel, your board type and device number
may not be displayed initially, and fewer tabs may be displayed at the
top of the display. If so, click the scroll buttons next to the Driver
Selection and Device Selection text boxes until your KPCI-3110 or
KPCI-3116 board type and device number are displayed. All six tabs
will then be displayed.
8. Click the Meter tab. An on-screen digital voltmeter appears, displaying the voltage con-
nected to Channel 00. Because Channel 00 is grounded, the displayed voltage should be
nominally zero.
9. Using your mouse, move the Channel Selection pointer of the on-screen digital panel meter
to 1.
NOTE To move the Channel Selection pointer, you must contact the wide part
of the pointer with the tip of the cursor.
10. The on-screen digital voltmeter now displays the voltage connected to channel 01.
11. Based on the displayed voltages in step 8 and step 9 , act as follows:
• If the channel 00 voltage displayed in step 8 is not 0V and/or if the channel 01 voltage
displayed in step 9 does not nominally agree with the applied voltage, then your board
apparently has analog input problems. Stop here, and return to the problem isolation step
in
“Problem isolation Scheme F: the board,” that asked you to perform the Analog input
hardware test.
•
If the channel 00 voltage displayed in step 8 is 0V and the channel 01 voltage displayed
in step 9 nominally agrees with the applied voltage, then the analog inputs are apparently
satisfactorily. Stop here, and return to the problem isolation step in “Problem isolation
Scheme F: the board,” that asked you to perform the Analog input hardware test.
NOTE
If the analog inputs appear to work satisfactorily but the displayed
channel 00 and channel 01 voltages appear to be nominally outside
specified limits, you may wish to calibrate your board after concluding
the systematic problem isolation procedure. For board specifications,
refer to Appendix A. For calibration procedures, refer to
Section 5 ,
“ Calibration .”
