A. Introduction
1.00 On-Site Administration
Description
You can administer system programming and
system maintenance by using the RS-232C
terminal (DEC VT220 (100) compatible). The RS-
232C terminal is connected to the KX-TD500 with
the RS-232C port #1. For details about RS-232C
communication parameters, refer to Section 10-
D-7.00 "Communication Interface".
The attendant console is also capable of
administrating system programming and system
maintenance. When you set the PRG MODE
switch to ON, the initial display of VT
programming mode appears on the screen.

The initial display appears on the screen (refer to
8-B-1.00 "Initial Screen") if the power switch is set
to ON after connection. If the initial display does
not appear, check whether the set up procedure
was done correctly (cable connection or
communication parameters).
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, a 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
VT220
level password, you can execute all functions,
compatible
but are increasingly restricted when entering
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 8-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 of 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.
