Note:
Using Method 1 Lockout all settings can be modi-
fied by anyone who knows how to find their way to
the [SLoC] and [rloC] parameters
Method 2- Enable Password Security [pas;e] and
then modify the Lock Level [loC;l] value
which ranges from 1 to 5. See the section
entitled Using Lockout Method 2 for more
detail.
Using Lockout Method 2 (Password Enable)
It is sometimes desirable to apply a higher level of
security to the RUI where a password would be re-
quired to access the menus. If Password Enabled
[pas;e]
in the RUI Page under the [`loC] Menu is
set to on, an overriding Password Security will be in
effect for the RUI. Without the appropriate password
(User or Administrator), specified menus within the
RUI will remain inaccessible based on the Locked Ac-
cess Level [loC;L] prompt. On the other hand, a User
with a password would have visibility restricted by
the Read Lockout [rloC]and the Set Lockout [sloC]
settings. As an example, with the following settings:
- Password [pas;e] Enabled
- Locked Access Level [loC;L] set to 1
- Read [rloC] and Set [sloC] Lock set to 5
a User (having entered a User password) would
have access to all menus with the exception of the
Lock menu. Therefore, Read and Set Lock cannot be
changed. If an Administrator enters the appropriate
password all menus would then become available
again.
How to Enable Password Security
Follow the steps below:
1. Go to the RUI Page by holding down the Advance
‰
key and the Down ¯ key for approximately six
seconds
2. Push the Down ¯ or Up ¿ key to get to the [`loC]
menu. Again push the Advance
‰
key until the
Password Enabled [pas;e] prompt is visible
3. Push either the Down ¯ or Up ¿ key to turn it on.
Once on, 4 new prompts will appear:
a. [loC;l], Locked Access Level (1 to 5) correspond-
ing to the lockout table above.
b. [roll], Rolling Password will change the Cus-
tomer Code every time power is cycled.
c. [pas;u], User Password which is needed for a
User to acquire access to the control.
d. [pas;a], Administrator Password which is needed
to acquire administrative access to the control.
The Administrator can either change the User and
or the Administrator password or leave them in the
default state. Once Password Security is enabled they
will no longer be visible to anyone other than the Ad-
ministrator. In other words the Lock Menu [`loC] is
not available to a User. As can be seen in the formula
that follows either the User or Administrator will
need to know what those passwords are to acquire a
higher level of access to the control. Back out of this
menu by pushing the Infinity ˆ key. Once out of the
menu, the Password Security will be enabled.
How to Acquire Access to the Control
To acquire access to any inaccessible Menus, go to the
RUI Page and enter the [UloC] menu. Once there
follow the steps below:
Note:
If Password Security (Password Enabled [pas;e] is
on) is enabled the two prompts mentioned below in
the first step will not be visible. If the password is
unknown, call the individual or company that origi-
nally setup the control.
1. Acquire either the User Password [pas;u] or the
Administrator Password [pas;a].
2. Push the Advance
‰
key until the Code [Code]
prompt appears.
Note:
a. If the the Rolling Password is off push the Ad-
vance
‰
key until the Password [pass] prompt
is displayed. Proceed to either step 7a or 8a.
Pushing the Up ¿ or Down ¯ arrow keys enter
either the User or Administrator Password. Once
entered, push and hold the Infinity ˆ key for two
seconds to return to the Home Page.
b. If the Rolling Password [roll] was turned on
proceed on through steps 3 - 9.
3. Assuming the Code [Code] prompt (Public Key) is
still visible on the face of the control simply push
the Advance key
‰
to proceed to the Password
[pass]
prompt. If not find your way back to the
RUI Page as described above.
4. Execute the calculation defined below (7b or 8b) for
either the User or Administrator.
5. Enter the result of the calculation in the upper dis-
play by using the Up ¿ and Down ¯ arrow keys or
use EZ-ZONE Confgurator Software.
6. Exit the RUI Page by pushing and holding the In-
finity ˆ key for two seconds.
Formulas used by the User and the Administrator to
calculate the password follows:
Passwords equal:
7. User
a. If Rolling Password [roll] is Off, Password
[pass]
equals User Password [pas;u].
b. If Rolling Password [roll] is On, Password
[pass]
equals: ([pas;u] x code) Mod 929 + 70
8. Administrator
a. If Rolling Password [roll] is Off, Password
[pass]
equals User Password [pas;a].
b. If Rolling Password [roll] is On, Password
[pass]
equals: ([pas;a] x code) Mod 997 + 1000
