Security
There are two security features available. You can enter a password to protect the configuration
files, and you can enable security encryption of the radio transmissions.
The password can be between 6 and 256 characters. The password is case sensitive and any
ASCII characters can be used. If you have entered a password, then this password will need to be
entered whenever the configuration is changed. You are able to change the password from the
“Utilities” menu. If unauthorized access to the files is a concern, we recommend that you change
the password regularly or whenever there is a change of staff.
Data Encryption is an additional level of security. The security option uses a 64 bit security key
to provide data encryption of the radio messages. All modules in the same system will be
configured with the same security key used to encrypt and decrypt the messages. This feature is
available for modules with firmware version 2.1 and higher. If you are adding modules to an old
system which does not have the security encryption feature, then you cannot use security
encryption on the new modules.
Note that the security key is different than the password.
•
To enable the security encryption, select the “Enable Security” box on the project display.
An 8-character random security key is automatically generated. If desired, a different security
key may be entered and you will be prompted to enter the security code a second time to
confirm. The security key can be any characters or numbers. Characters are case sensitive.
The security key will never be displayed.
