OPTIMOD SURROUND PROCESSOR INSTALLATION

B) Choose whether you want the 8685 to delete all passcodes while retaining
other customizations (like I/O levels and user presets) or if want the 8685 to
reset itself to its factory defaults. In either case, all existing passcodes will be
erased.
• If you choose to reset the unit to factory defaults, the 8685 will subse-
quently ask whether it should erase all user presets or retain them.
• If you choose to only delete passcodes, the front panel will not unlock
automatically. After you have deleted the passcodes, there will be only one
passcode, ADMIN, which has All Access privileges. Use this passcode to
unlock the front panel normally.
• If you reset the unit to its factory defaults, the panel will unlock automati-
cally. Please note that resetting the unit to its factory defaults:
• Resets all global parameters to factory default settings
• Deletes all Automation Events
• Restores Remote Interface inputs 1-8 to “no function”.
Administering the 8685 through its RS-232 Serial
Port or Ethernet
You can connect a PC to the 8685’s RS-232 serial port or to its Ethernet port by using
a terminal program like HyperTerminal to administer security and to recall presets
using simple ASCII commands.
You must configure the 8685 so that it loads the correct serial port driver when
booting up. You do this by setting the serial interface type in the N
ETWORK screen
and then rebooting the 8685. There are two available drivers: One driver supports
simple ASCII commands; the other driver supports communication via TCP/IP and PPP.
Using the RS-232 port to connect to 8685 PC Remote software via a direct
cable connection or modem requires configuring the port as PPP. How-
ever, in most cases you will use Ethernet to connect to PC Remote.
The 8685’s two RS-485 ports (Serial Ports 2 and 3) are dedicated to send-
ing and receiving Dolby Digital metadata; they cannot be used to control
the 8685.
• Valid commands are in either upper or lower case, not a combination.
• Only one valid command is permitted per line.
• The 8685 will not respond to unrecognized commands.
• The character code supported is ASCII.
