Diagnostics
The PDR200 diagnostics program, resident on the system hard drive, provides
board-level fault isolation. This program consists of an application written for the
Windows NT operating system and the i960 computer machine code. The diagnostics
program is intended to isolate problems to the board level including the Mother
Board.
The Windows NT operating system, which runs on the system processor, provides the
graphic user interface (GUI) and data logging, configuration, and date/time
information.
The i960 executed files perform the diagnostics and exerciser tests, make pass/fail
decisions, count the errors for the current test, print pass/fail error messages in the
i960 window, and report pass/fail information (in ASCII format) to the Profile.log
through the system processor. The system processor appends the date and time to the
report, and creates or updates the appropriate log files.
Starting the Diagnostics Program
To start the diagnostics program, open the PDR Debug Tools group and select the
PDR Diagnostics icon as shown in Figure 4-2.
Figure 4-2. Starting The PDR Diagnostics Program
As the PDR Diagnostics start up, the cursor appears momentarily as an hourglass,
indicating that the program is checking the board configuration of the PDR200. (The
diagnostics program can only identify boards that have an EISA identification). The
Diagnostics window then appears (see Figure 4-3 for an example).
If this windows appears, the diagnostics program is running and some (if not all) of
the diagnostic program is intact. If the board configuration fails to appear on the left,
bad or missing software is probably the cause. Note that when the Diagnostics
window opens, the following message may appear:
Checking availability of VDR Services. Please wait. . .
After approximately one minute, this message goes away and you may proceed. If it
does not go away, restart the Profile and the Diagnostics program. If the message still
does not go away, contact Grass Valley Group Product Support (see front of manual).
