KPCI-3101 — KPCI-3104 Series User’s Manual
NOTE
If the analog outputs appear to work satisfactorily, but some measured
analog output voltages are outside the accuracy limits specified in
Appendix A, consider calibrating your board after concluding the sys-
tematic problem isolation procedure. For calibration procedures, refer

General-purpose digital I/O hardware test
This test checks whether the general-purpose digital input and output circuits of the board are
operating properly.
All I/O is set and read using the DriverLINX Digital Input/Output test panel, and no instruments
are required. However, you must wire an STA-300 screw terminal accessory in the loop-back
configuration. 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.
The following summarizes the test procedure:
•
Wire an STA-300 screw terminal accessory in a loop-back configuration. Connect the chan-
nel 0 digital I/O terminals, bit-for-bit, to the channel 3 digital I/O terminals. Connect the
channel 1 terminals, bit-for-bit, to the channel 2 terminals.
•
Using a DriverLINX graphical interface, configure the channel 0 and 1 bits as outputs and
the channel 2 and 3 bits as inputs.
•
Using the same DriverLINX graphical interface, set the channel 0 and 1 outputs in a particu-
lar bit pattern and check channels 2 and 3 inputs for the same bit pattern. Repeat, using a sec-
ond bit pattern.
The digital I/O of the board is performing satisfactorily if all bits respond appropriately. Choose
bit patterns that check both for direct ON/OFF response and for shorts between bits.
Specified software I/O tests
The tests in this section check whether your application software correctly performs analog and
digital I/O tasks. The I/O are tested using a KPCI-3101–4 board known to work properly,
thereby bypassing potential board problems. These tests are intended to be used when specified
in the preceding systematic problem isolation procedure.
NOTE
During these tests, disconnect all user circuits from the board, except for
connections specified in individual test procedures.
Analog input software test
This basic analog input test checks whether your application software correctly monitors DC
analog inputs. You ground analog channel 0, apply a DC voltage to channel 1, and measure the
results.
NOTE
During this test, ensure that no user circuits are connected to the
KPCI-3101–4 board, via the required screw terminal accessory, except
for analog input connections specified for the test.
