Firmware Update
You can update the firmware on your panel with the TX3 Configurator software
by using one of the following methods.
•
Firmware Upgrade Wizard
•
Network Firmware Upgrade
The Firmware Upgrade Wizard can be used to update only one panel at a time. It
will work on any panel.
The Network Firmware Upgrade procedure can update more than one panel at
the same time. In order to use the Network Firmware Upgrade, all of the panels
must already have firmware that supports this feature installed on them.
Refer to LT-995 TX3 System Configuration and Administration Manual for
instructions on how to perform both of these firmware upgrade methods. LT-995
can be found on the TX3 Configurator Software installation CD, USB flash
drive, or on the Mircom website.
