Serial Port Communications and Commands
Command Explanations
To change the password for Access Level 1, enter the following:
=>>PAS 1 <Enter>
Old Password: *********
New Password: ******
Confirm New Password: ******
Password Changed
=>>
Similarly, PAS B and PAS 2 can be used to change the level B and level 2
passwords, respectively.
The new password will not echo on the screen, and passwords cannot be
viewed from the device. Record the new password in a safe place for future
reference.
If the passwords are lost or you wish to operate the relay without password
protection, put the main board Password jumper in place (Password jumper =
ON). Refer to Table 2. 6 and Table 2.7 for Password jumper information.
While the password protection is disabled by setting the main board Password
jumper in place (Password jumper = ON), lost or forgotten passwords can be
assigned a new password, by using the PAS x command at Access Level 2.
The relay will prompt for a new password and a confirmation of the new
password.
If you wish to disable password protection for a specific access level [even if
the Password jumper is not in place (Password jumper = OFF)], simply set the
password to DISABLE. For example, to disable password protection for
Level 1, enter PAS 1. When the relay prompts for the new password and a
confirmation of the new password, enter DISABLE. The relay will respond
with
Password Disabled.
Passwords may include as many as 12 characters. See Table 10.9 for valid
characters. Upper- and lowercase letters are treated as different characters.
Strong passwords consist of 12 characters, with at least one special character
or digit and mixed-case sensitivity, but do not form a name, date, acronym, or
word. Passwords formed in this manner are less susceptible to password
guessing and automated attacks. Examples of valid, distinct strong passwords
include:
➤ Ot3579A24.68
➤ Ih2d&s4u-Iwg
➤ .351s.Nt9g-t
The relay shall issue a weak password warning if the new password does not
include at least one special character, number, lowercase letter, and uppercase
letter.
