IN1804 Seamless Scaling Switchers • Operation 43
NOTE: The reset modes listed close all open IP and Telnet connections and all sockets.
Each mode is a separate function, not a continuation from mode 1 to mode 5.

Use Factory Firmware
1
Using an Extron Tweeker or other small
screwdriver, press and hold in the
recessed Reset button for 30 seconds
while applying power to the switcher.
NOTE: After a mode 1 reset,
update the device with the latest
firmware version. DO NOT
operate with the firmware version
that results from this type of reset.
This temporarily resets the device
to factory default until power is
recycled. To use factory default
firmware, upload that version
again.
The device reverts to the factory default
firmware.
• Firmware reverts to the factory default for a
single power cycle.
• All user files and settings (drivers, audio
and video adjustments, IP settings, and so
on) are maintained.
NOTE: If you do not want to update the
firmware or perform a mode 1 reset by
mistake, cycle power to the device to
return to the firmware version running
prior to the reset.
Use mode 1 to revert
to the factory default
version if incompatibility
issues arise with
user-loaded firmware.
Reset IP
Settings
4
Hold down the Reset button until the
Reset LED blinks twice (approximately
6 seconds). Then, press Reset
momentarily (less than 1 second).
IP settings revert to factory defaults.
• Port mapping reverts to factory default.
• DHCP turns off.
• IP address is set to 192.168.254.254.
• Reset LED blinks four times in quick
succession during reset.
Use mode 4 to reset
all IP settings back to
factory defaults.
Reset to Factory Default
5
Hold down the Reset button until
the Power LED blinks three times
(approximately 9 seconds). Then,
press Reset momentarily (less than
1 second).
The device reverts to the factory defaults
except for firmware.
• Mode 4 results are performed.
• All user modifiable configurations are reset
to default values including IP settings and
real-time adjustments.
• All user loaded files are deleted.
• The Reset LED blinks 4 times in quick
succession during the reset.
Use mode 5 to
restart with default
configuration. This
is equivalent to SIS
command ZQQQ.
This reset also removes
the initial serial number
password and sets it to
no password.
RS-232 and IR Signal Insertion
The twisted pair input and output ports allow you to insert RS-232 and IR control signals
onto the same cable that carries video and audio to extend them to the Over TP port on a
connected endpoint (see figure 31 on the next page, figure 32 on page 46, and figure 33
on page 47). The control signals can be inserted in the following ways:
• Ethernet to RS-232 insertion (see Ethernet to RS-232 Insertion on the next
page) — A control signal applied to the IN1804 LAN port can be routed to the RS-232
port of any connected twisted pair device. The RS-232 insert inputs and outputs
inserted via Ethernet can support up to a 115K baud rate.
• Captive screw insertion (see Captive Screw IR Signal Insertion on page 46) — (IR
only) A control signal applied to the IR Over TP captive screw port is tied directly to the
TP IN4 (DI and DI/DO models only) or to the TP Output 1A (DO and DI/DO models only).
You must physically connect a cable to the captive screw connector where a control
signal is to be inserted.
