DIAGNOSTICS
Service Diskette #3
Introduction Service Diskette #3 contains a diagnostic program and
support files that test the DIMENSION tape drive, tape
drive interface board , interface harness and tape cassettes.
The test program, TBU.EXE, is completely menu-driven
(explanations of the menu options follow). After a menu
selection is made, no further attention to the program is
required. The diagnostic program permits tests on the
system to run for as long as 99 hours before indication of
successful completion or failure. Test completion is clearly
signaled and the status of the tape drive and associated
electronics is indicated with PASS/FAIL/RETEST results.
A separate menu provides technicians with the means to
alter test parameters. This menu also allows individual
commands to be transmitted to the drive during evaluation
or troubleshooting.
Program
The test program may be easily customized for special
Customization applications by saving alterations to the program in a file
called INITXX.VAL. This file may then be used at any time.
The INITXX.VAL file is able to store two customized
programs:
* one that may be used in a repair facility
* one that may be used in the field
Each test may be changed without affecting the other.
DOS and You MUST use DIMENSION DOS version 1.2.0 or later from
TBU.EXE a fixed disk boot to run tape diagnostic program contained
