Resetting the Unit
There are four reset modes (numbered 1, 3, 4, and 5 for the sake of comparison
with an Extron IPL product) that are available by pressing the Reset button on the
side 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 modes.
C Review the reset modes carefully. Using the wrong reset mode may result
in unintended loss of fl ash memory programming, port reassignment, or a
controller reboot.
N The reset modes listed below close all open IP and Telnet connections and close
all sockets. Also, the following modes are separate functions, not a continuation
from Mode 1 to Mode 5.
Reset Mode Comparison/Summary
Mode Activation Result Purpose/Notes
1 Hold down the recessed
Reset button while applying
power to the MLC.
After a mode 1 reset
is performed, update the
MLC’s firmware to the
latest version. Do not
operate the MLC firmware
version that results from the
mode 1 reset. If you want to
use the factory default
firmware, you must upload
that version again. See
appendix B, “Firmware
Updates,” for details on
uploading firmware.
3 Hold down the Reset button
for about 3 sec. until the
Reset LED blinks once, then
press Reset momentarily
(<1 sec.) within 1 second.
4 Hold down the Reset button
for about 6 sec. until the
Reset LED has blinked
twice (once at 3 sec., again
at 6 sec.). Then press Reset
momentarily (for <1 sec.)
within 1 second.
5 Hold down the Reset button
for about 9 sec. until the
Reset LED has blinked three
times (once at 3 sec., again
at 6 sec., again at 9 sec.).
Then press Reset
momentarily (for <1 sec.)
within 1 second.
The MLC reverts to the factory default
firmware.
Event scripting will not start if
the MLC is powered on in this mode. All
user files and settings (drivers,
adjustments, IP settings, etc.) are
maintained.
If you do not want to update
firmware, or you performed a mode 1 reset
by mistake, cycle power to the MLC to
return to the firmware version that was
running prior to the mode 1 reset. Use the
0Q SIS command to confirm that the
factory default firmware is no longer
running (look for asterisks following the
version number.)
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
• 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 events off.
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 almost all the real time
adjustments: all audio settings, limit
initial power up volume, power
up/down delay, auto power down, and
misc. options. This does not affect an
optional MLS switcher, however.
• Clears driver-port associations and port
configurations (IR/RS-232).
• Removes button configurations.
• Resets all IP options.
• Removes scheduling settings.
• Removes/clears all files from switcher.
The Reset LED flashes 4 times in quick
succession during the reset.
Use mode 1 to revert
to the factory default
firmware version if
incompatibility issues
arise with
user-loaded firmware.
Mode 3 is useful for
troubleshooting.
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 configuration
and uploading, and
also to replace events.
