User Diagnostics; Terminal Diagnostics - Digi PortServer II User Manual

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 (
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.
