Correct bit patterns when port A is set to bit pattern 2.
18. Based on the observations in step 17, do the following:
•
If the bit patterns for ports A, B, and C do not all agree, the board is not functioning prop-
erly. Stop here, and return to the step in the “General problem isolation procedure” where
you were directed to do I/O bit tests (step 17 or step 26e in the “General problem
isolation procedure”).
•
If the bit patterns for ports A, B, and C do all agree, but you have not performed the loop-
back test for all four port groups, then repeat steps 2 through 14 for the next port group.
•
If the bit patterns for ports A, B, and C do all agree, and you have performed a loop-back
test for all four port groups, the board is functioning properly. Stop here, and return to the
step in the “General problem isolation procedure” where you were directed to do I/O bit
tests (step 17 or 26e in the “General problem isolation procedure”). Or, optionally, now
perform the output set test, as discussed in the next section, if you have not already
done so.
Output set test
The output set test checks whether logic levels measured at all KPCI-PIO96 output pins agree
with output bit patterns set by software, using a DriverLINX graphical interface.
NOTE
This test is performed without user circuits being connected to
the outputs.
Perform the output set test as follows:
1. Ready the following equipment:
•
A digital voltmeter (DVM) or a digital multimeter (DMM) set to measure voltages, or a
logic probe capable of reading TTL logic levels.
•
A means to reliably and safely connect the DMM/DVM or logic probe input to each I/O
pin. The following alternatives are suggested:
a. A cable assembly and terminal accessory (refer to “Using manufactured cables and
accessories” in Section 3).
b. A 50-pin mating connector (3M part no. 3425-6050) with installed ribbon cable, such
that the meter or logic probe can be clipped to exposed conductors at the end of
the cable.
