1.01 Logging in to the System
Description
You can administer the system programming and
maintenance of the system using a dumb
terminal.
For details about communication parameters,
refer to Section 10-D-7.00 "Communication
Interface".
System Security
For security reasons, access to the
administration capabilities of the system is
controlled by a password.
To prevent an unauthorized person from learning
the password, the password characters are not
displayed when they are entered.
Password
To gain access to the system administration
feature, a valid password (4-digit, Alphanumeric
characters *) must be entered.
To be recognized by the system, password must
be entered exactly as stored in memory.
Factory programmed 8 passwords are provided
from the 1st to 4th level for on-site operation and
1st to 4th level for operation from a remote
location individually.
When you enter the correct password, the
terminal displays the Dumb Initial Screen from
which you can enter into programming mode or
operation mode.
The followings are the functions available to each
password level.
1st Level Access to all levels
2nd Level Set System level parameters
3rd Level Set Port level parameters
4th Level Read parameters only.
When you log in to the system using the 1st level
password, you can execute all functions, but are
increasingly restricted when entering level 2, 3
and 4.
Passwords are originally factory programmed,
but may be changed when logging in to the
system by entering the 1st level password.
Refer to Section 9-F-1.00 "Change Level (CHL)"
for changing password level.
* Alphanumeric characters
ASCII codes except special codes (DEL, ESC
etc.)
But entering " " "~" are not available, because
these characters cannot be displayed on the
display of PITS.
Both uppercase and lowercase characters
can be recognized by the system.
1.02 Dumb Operation Mode
When you log in to the system administration
terminal, "Select the Mode" screen appears on
the display.
At initial prompt in this screen, you can enter into
programming mode by entering PRG, and
operation mode by entering OPE.
In programming mode, assigning and changing
the system programming parameters can be
done. In operation mode, monitoring, testing and
maintaining the system can be done.
Refer to Section 9 "Preparation for Programming
and Maintenance (Dumb Type Terminal)" for
further details about Dumb operation mode.
