Security and Passcode Programming
[Skip this step if you do not plan to use PC Remote software or do not plan to lock
out the front panel locally.]
The 8500S has several levels of security to prevent unauthorized people from chang-
ing its programming or operating state. Security controls access to the front panel
and to anyone connecting to the 8500S through a direct serial connection, dial-up
networking (through modems), or its Ethernet port.
The security levels are:
1. All Access (i.e., administrator level)
2. All Access except Security
3. All Access except Modify and Security
4. Recall, Modify and Automation
5. Recall Presets and Program Automation
6. Recall Presets
There is a default All-Access passcode:
1234
. This allows PC Remote users to connect
to the 8500S if they forgot to add a passcode from the 8500S’s front panel. Like any
other default passcode, it should be erased and replaced by a strong custom pass-
code as soon as possible.
See To Delete a Passcode on page 2-40 and To Create a
Passcode below. Note that if you fail to create a custom passcode and merely delete
the
1234
passcode, the
1234
passcode will be regenerated automatically the next
time your Optimod is turned off and back on.
The Optimod’s front panel cannot be locked out unless the Optimod has been as-
signed at least one All Access
passcode.
The 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.
