Upgrading Firmware
The Room Alert 4E rmware is upgraded using the AVTECH Device Discovery Utility and Room Alert
4E Firmware Update le. The latest version of these les can be obtained from the ‘Downloads’ section
of the AVTECH.com website. If the AVTECH Device Discovery Utility is already installed on the
computer being used for the upgrade, check for an updated version before downloading the Room Alert
4E Firmware Update le.
NOTE: When saving the Room Alert 4E Firmware Update le to the computer, it may be saved with either a ‘.zip’ or ‘.upd’ le
extension. If the extension is ‘.zip’, DO NOT EXTRACT the Room Alert 4E Firmware Update le.
After obtaining the most current version of the AVTECH Device Discovery Utility and the Room Alert
4E Firmware Update le, be sure to install the AVTECH Device Discovery Utility on the system that
will be used to upgrade the Room Alert 4E rmware (if it is not already installed).
IMPORTANT NOTE: Be sure that there are NO WEB BROWSERS ACCESSING the Room Alert 4E unit from anywhere on
your network before uploading the rmware as this could cause the rmware update to be incomplete or become corrupted.
When completed, open the AVTECH Device Discovery Utility and click the ‘Search’ button. When the
Room Alert 4E unit is located, select it and click the ‘Upgrade’ button. If the unit can not be located
although is accessible via a web browser, skip to the ‘Unit Accessible Although Not Discoverable’
section below. Navigate to the location where the Room Alert 4E Firmware Update le was saved, select
it and click the ‘Upload’ button. A dialog will then load asking for conrmation of the rmware upload.
Click ‘Ok’ to upload the Room Alert 4E Firmware Update le to the Room Alert 4E unit.
Reset Factory Default Settings
There are two primary methods for returning TemPageR to the factory default settings. This can be
useful if the unit is assigned invalid network settings and is no longer accessible or if the unit will
be moved to a new location and will be recongured. If the unit is accessible on the network and the
‘Settings’ screen can be accessed, clicking the ‘Reset Defaults’ button on the left menu of the ‘Settings’
screen will restore the factory default settings to the device. If the unit is not accessible on the network,
the reset button on the back of the unit can be used to reset the factory default settings. With the unit
connected to the network and powered on, press and hold the reset button approximately 5-10 seconds
until the left LED over the network jack turns off then on again. Once the settings have been reset to
defaults, the unit will automatically reboot and attempt to obtain a new DHCP IP address.
Unit Accessible Although Not Discoverable
In the event that the network blocks UDP broadcast packets on port 30718, the AVTECH Device
Discovery Utility will not be able to locate the Room Alert 4E unit even though it is accessible via a web
browser. As long as the Room Alert 4E unit can be accessed via a web browser, the AVTECH Device
