Step 5 Checking Operations with the Diagnosis
Program
Use the diagnosis program to check that the board and driver software work normally, thereby you can
confirm that they have been set up correctly.
What is the Diagnosis Program?
The diagnosis program diagnoses the states of the board and driver software.
It can also be used as a simple checker when an external device is actually connected.
Using the “Diagnosis Report” feature reports the driver settings, the presence or absence of the board,
I/O status, and interrupt status.
Check Method
To check analog I/O data, connect the signal.
The diagrams below show examples of using channel 0 on the AO-1604CI2-PCI. For details on the
connections, see Chapter 3 “External Connection”. Check the board with the factory defaults
untouched.
