A. Introduction
1.00 On-Site Administration
Description
You can administer the system programming and
maintenance of the system using a Dumb
terminal.
For details about communication parameters,
refer to Section 9-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 (four-digit,
alphanumeric characters*) must be entered.
To be recognized by the system, the password
must be entered exactly as stored in memory.
Factory programmed eight passwords are
provided from the first to fourth levels for on-site
operation and the first to fourth levels for
operation from a remote location.
The followings are the functions available to each
password level.
The 1st Level : To access to all levels.
The 2nd Level : To set system level parameters.
The 3rd Level : To set port level parameters.
The 4th Level : To read parameters only.
When you log in to the system using the first
level password, you can execute all functions,
but are increasingly restricted when entering the
levels 2, 3 and 4.
Passwords are originally factory programmed,
but may be changed when logging in to the
system by entering the first level password.
Refer to Section 7-E "Changing Password."
* Alphanumeric characters
ASCII codes except special codes (DEL, ESC
etc.) But entering "/" "~" are not available,
because these characters cannot be displayed
on the LCD (Liquid Crystal Display) of a PITS.
Both uppercase and lowercase characters can
be recognized by the system.
Successful Login
When you enter the correct password, the
terminal displays the Main Menu screen from
which you can select administration functions.
By selecting an item from the Main Menu, you
enter a system programming area and can
access specific system parameters and features.
