Serial Port Communications and Commands
Command Set
After entering your new passwords, use the PAS command, as shown in
Figure 8.25, to view the new settings. The following example shows how to
use the PAS command for viewing and setting passwords. When setting your
passwords, be sure to choose “strong” passwords that cannot be guessed or
broken easily with automated “password cracking” software.
*>>PAS 1 <Enter>
New level 1 password: ? ******
Verify new level 1 password: ? ******
Level 1 password changed
*>>PAS 2 <Enter>
New level 2 password: ? ******
Verify new level 2 password: ? ******
Level 2 password changed
*>>PAS <Enter>

Figure 8.25 PASSWORD Change Sequence
If you are certain that your physical control of all access to the SEL-2032 is
sufficient to prevent unauthorized access, or if the devices connected between
the SEL-2032 and any other access points provide sufficient protection from
unauthorized access, then you may disable password protection.
To disable passwords at a specific level, enter the keyword DISABLE instead
of a password when setting the password.
The SEL-2032 sets the password and asserts the SALARM global element for
approximately one second. In the SEL-2032, SALARM is assigned to
ALARM by default, so the alarm contact will close for one second unless the
ALARM setting has been modified. After entering new passwords, type PAS
<Enter> to inspect them. Make sure they are what you intended, and record
the new passwords.
If the passwords are lost or you wish to operate the SEL-2032 without
password protection, install the Password Jumper (J17 B in the SEL-2032) on
the main board (see Jumper Settings on page 2.1 for jumper location). With no
password protection, you and others can gain access without knowing the
passwords and view or change active passwords and settings.
Using Strong Passwords
It is important that you establish strong password protection to safeguard
against unauthorized persons setting or controlling your SEL-2032 and the
devices attached to it. Strong passwords consist of at least six 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:
Ot3579 A24.68 Ih2dcs 4u-Iwg Ic-4+
NOTE: Do not use characters that
you have selected as LMD prefix
characters. See Section 9: Protocols,
for a description of LMD prefixes.
Used properly, passwords provide good protection against unauthorized
access. Make sure you choose strong passwords and record them in a secure
location. If your passwords are forgotten and lost, you will need to install the
main board password jumper in order to disable password protection long
enough to view them with the PAS command.
