over the serial port using DeviceInstaller’s Recover Firmware procedure. (See 10: Firmware

Port 77FE will prevent users from accessing the setup menu from the network. Port 77FE is
a setting that allows DeviceInstaller, WebManager, and custom programs to configure the
unit remotely. You may wish to disable this capability for security purposes.

Note: The default setting is the N (No) option, which enables remote configuration. You can
configure the unit by using DeviceInstaller, web pages, Telnet, or serial configuration. The Y
(Yes) option disables remote configuration and web sites. The Y (Yes) option also disables
many of the GUI tools for configuring the unit, including the embedded WebManager tool.

Enable Encryption
Rijndael is the block cipher algorithm chosen by the National Institute of Science and
Technology (NIST) as the Advanced Encryption Standard (AES) to be used by the US
government. The Micro125 supports 128-, 192-, and 256-bit encryption key lengths.
Note: Configuring encryption should be done through a local connection to the serial port of
the Micro125, or via a secured network connection. Initial configuration information, including
the encryption key, is sent in clear text over the network.
