6. Recall Presets
Only passcodes with
A
LL
A
CCESS
let you do software updates and set passcode per-
missions.
Each Passcode is unique; the software will not let you create duplicate Passcodes.
Further, to prevent accidental lockout, the software requires you to have at least
one passcode with
A
LL
A
CCESS
(administrator) privileges.
Your Optimod secures User Presets by encrypting them (using the Advanced Encryp-
tion Standard algorithm with the session passcode as its key) when PC Remote
fetches them. Hence, a packet sniffer cannot intercept User Presets in plaintext form.
PC Remote then writes the fetched User Presets in encrypted form on your hard
drive, where they remain for the duration of your PC Remote session.
If PC Remote exits normally, it will erase these temporary User Preset files
from your computer’s hard disk. If it does not exit normally, these files
will remain in encrypted form. However, the next time that PC Remote
starts up, it will automatically clean up any orphaned files.
1. From the main menu, locate to
S
YSTEM
S
ETUP
and then to
S
ECURITY
.
The Security screen lets you set front-panel lockout time, choose if you want the
meters to be viewable when the 8685 is in lockout mode, create new passcodes,
review and/or assign authorization levels for existing passcodes, and delete pass-
codes.
If the 8685 is already under security control, you must enter an
A
LL
A
CCESS
-level
passcode to enter the Security screen.
2. Set the Security Screen “Lockout” parameter.
The choices are 1, 5, 15, or 30 minutes, 1, 2, 4, or 8 hours, or
O
FF
.
Front Panel lockout only occurs when the lockout value is not
O
FF
.
The Lockout field sets the time delay between the last user interaction with the
front panel and automatic front-panel lockout. Once the front panel is locked
out, you can only regain access by entering a valid passcode.
The Lockout field does not affect PC Remote connections. Once connected, the
PC Remote application does not time out automatically; it remains connected un-
til explicitly disconnected by its user.
The lockout timer begins at the top of the next minute. For example, if you set
Lockout to be 1 minute at 9:10:33 AM and do not touch the front panel again,
the front panel will lock out at 9:12:00 AM.
3. Set the Security Screen “View Meters” parameter.
Select Y
ES
to display meters and N
O
to hide meters when lockout is active.
