recommend that all system additions and changes be made to the archived configuration files first, and
then downloaded to the module/s. This ensures that the archived files are always maintained and
accurate. If you modify the configuration of a module by uploading and then downloading, then the
module configuration will be different then the archived files.
If you lose the configuration files for a system, then you can rebuild the configuration by uploading the
configuration file from every module in the system.
4.3.6 Print Options
You can obtain a print-out of each module configuration. On each unit display, there are “Unit
Summary” and “Mapping Summary” windows. Each of these will display a printable information page
about that module. The Unit Summary page will display the user options configured, and the Mapping
Summary will display the mappings entered for that unit.
The printer may be selected from the Printer Setup option in the File menu.
4.3.7 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 if
the configuration is to be changed later. You can view the configuration, but you will not be able to
make any changes. You are able to change the password from the “Utilities” menu. If unauthorised
access to the files is a concern, we recommend that you change the password regularly or whenever
there is a change of staff.
Security Encryption is an additional level of security. The security option uses an 8-character security
key to provide 64-bit 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 serial numbers with the middle three numbers greater than 210 - that is
xxxx210xxxx, or xxxx220xxxx etc. 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 security key is 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.
• If you do not enable security, there will be no data encryption of the radio messages. This is the
default setting.
• If a security key has been entered, this key is downloaded into each module as part of the
configuration download process. You can download another configuration at any time - if the
security key is different, or if there is no security key in the new configuration, the old key will be
