Output set test
The output set test checks whether logic levels measured at all output pins agree
with output bit patterns set by software, using a DriverLINX graphical interface (AIO
Panel).
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 suitable accessory and cable for the board being tested.
2.
Turn OFF the host computer.
3.
Connect the cable and accessory to your board.
4.
Turn ON the host computer and boot Windows 95/98/NT.
