General troubleshooting
The console port allows you to see detailed diagnostic messages when faults in
the oscilloscope prevent display of the normal diagnostics. Use this procedure to
set up the console port:
NOTE. You may need a DB-9 to DB-25 adaptor, null modem adaptor, gender
changer adaptor, and an extension cable to connect the console port to your
personal computer (see Figure 6--30 on page 6--30). Using Table 6--9 as a guide
you can wire a cable to take the place of a DB9 to DB25 adaptor, null modem
adaptor, gender changer, and an extension cable.
1. Equipment required: Console port (Item 1), a personal computer or
terminal (Item 2), and telecommunication (terminal) software (Item 4) for
the personal computer. Your personal computer may also require a DB-9 to
DB-25 adaptor, null modem adaptor, gender changer adaptor, and an
extension cable to connect the console port to your personal computer (see
Figure 6--30 on page 6--79).
2. Prerequisites: Power off the oscilloscope.
