User Diagnostics
You can run diagnostics either from a terminal (or PC with terminal emulation soft-
ware) connected to Port 1 or from PortServer II’s front panel. Diagnostics can be
selected any time before the POST test described above finish. To select diagnostics:
•
From the terminal:
Enter either “
V
” or “
v
” at a terminal connected to Port 1.
•
From the front panel:
Press either of the “arrow” pushbutton (
<
or
>
).
Important:
When you run diagnostics from a terminal or PC that is connected to
a serial port, the DTR and RTS lines on the serial port will be low
(inactive). Ensure that your terminal or PC will send the
“
v
”
character
when these lines are low. When in doubt, or you encounter problems,
use a 3-wire connection to the terminal or PC.
Terminal diagnostics
1. If you have not already done so, set the terminal connected to Port 1 to 9600 baud,
8 data bits, 1 stop bit, and no parity before you begin diagnostics.
2. Press
V
to enter diagnostic mode and check that the start-up screen shown below
appears. The screen displays test information, and waits for user input.
