Equipment for the analog input hardware test
The following equipment is needed for the analog input test:
•
A voltage source supplying a known voltage at < 5V. Refer to
Table C-1
for more details.
•
(Optional) A Digital Voltmeter (DVM) or a Digital Multimeter (DMM) to accurately deter-
mine the voltage of the voltage source.
•
An STP-3110
screw terminal accessory wired as shown in
Table C-1
. (These are the same
connections as made for the analog input
software
test.)
If possible, use a screw terminal accessory that is reserved for I/O tests. Avoid using a screw
terminal accessory that is normally connected to your external circuits. You thereby avoid the
extra labor and potential wiring errors involved in disconnecting and later reconnecting your
external circuits.
CAUTION
If you use the +5V board power to energize a voltage divider, ensure
that the +5V board power terminal cannot accidentally short to
ground. A short to ground can damage one or more of the following:
the screw terminal accessory, the board, the computer.
Procedure for the analog input hardware test
Perform the analog input test as follows:
1. Turn off the host computer.
2. Wire a screw terminal accessory as described under “
Equipment for the analog input hard-
ware test
.”
3. Connect the screw terminal accessory, as wired in
step 2
, to the KPCI-3110 or KPCI-3116.
4. Turn on the host computer and boot Windows 95, 98, or NT.
5. In the
Start
menu, click
Programs.
6. Find the
DriverLINX

Test Panels
folder, under which you should find the
AIO Panel
entry.
