Resetting the Unit with the Reset Button
There are four reset modes (numbered 1, 3, 4, and 5 for the sake of comparison
with Extron IPL products) that you can access 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 press it. See the table below for a summary of the reset modes.

ISM 824 Integration Scaling Multiswitcher • Operation and Setup
Review the reset modes carefully. Using the wrong reset mode may result
in unintended loss of flash memory programming, port reassignment, or
processor reboot.
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.
Result
Mode 1 causes the ISM 824 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
Adjustments
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.
Notes
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.
