Resetting the Unit
There are four reset modes (numbered 1, 3, 4, and 5) that are available by pressing
the Reset button on the rear panel. The Reset button is recessed, so use a pointed
stylus, ballpoint pen, or Extron Tweeker to access it. See the following table for a
summary of the reset modes.

Mode 1 causes the DVS 304 to revert to
the factory default firmware.
Event
scripting does not start if the unit is
powered on in this mode. All user files
and settings (drivers, audio adjustments,
IP settings, etc.) are maintained.
Mode 3 turns events on or off. During
resetting, the Reset LED flashes 2 times if
events are starting; 3 times if events are
stopping.
Mode 4 does the following:
• Enables ARP capability.
• Sets the IP address back to factory
default.
• Sets the subnet back to factory default.
• Sets the default gateway address back
to the factory default.
• Sets port mapping back to factory
default.
• Turns DHCP off.
• Turns all events off.
The Reset LED flashes 4 times in quick
succession during reset.
Mode 5 performs a complete reset to
factory defaults (except the firmware).
• Does everything mode 4 does.
• Resets everything that was set via the
Real Time Admustments part of the
control program: all video settings
and miscellaneous options.
• Resets all IP options.
• Removes/clears all files from the
processor.
The Reset LED flashes 4 times in quick
succession during the reset.
Use mode 1 to
remove a version of
firmware if
incompatibility
issues arise.
Events must be
turned on if you
want to change IP
settings or
scheduling.
Mode 4 enables you
to set IP address
information using
ARP and the MAC
address.
Mode 5 is useful if
you want to start
over with control
software
configuration and
uploading, and to
replace events.

C Review the reset modes carefully. Using the wrong reset mode may result
in unintended loss of flash memory programming, port reassignment, or
processor reboot.
N The reset modes listed in the table close all open IP and Telnet connections and
close all sockets. Also, each mode is a separate function, not a continuation from
mode 1 to mode 5.
System Reset
For a scaler reset, the DVS 304 can return to default values by holding down the
Input 1 button while simultaneously plugging in the power cord. The System Reset
message will be displayed on the LCD screen.
