3. Configuration
3.1 User Interfaces
The RFI-9256 provides three user interfaces that allow the radio to be configured for a diverse range of
applications.
1. Terminal menu interface. A menu system is available over either of the RFI-9256’s serial ports.
This menu interface can be accessed through a terminal emulation program, such as RFI InTerm.
2. AT command interface. The AT command interface is used to configure and control to the RFI-
9256 through ASCII Hayes attention commands. This can be used to adjust the radio’s configuration,
read the radio’s configuration, and read performance parameters.
3. Front panel interface. The front panel interface consists of six dual colour (red / green) LEDs and a
push button. This panel can display the radio status, RSSI, transmit power, temperature, and main
serial port status.
3.2 Terminal Menu Interface
The terminal menu provides access to all configuration parameters in the radio. There are three methods for
accessing the terminal menu:
1. Execute the
AT?
command at the Hayes AT command interface. See section 3.3 information on
executing AT commands.
2. Dial a remote radio’s menu system using AT commands. See section 4.3.3 for more information on
connected to remote radios via AT commands. When a menu system is accessed remotely its
functionality is limited in order to prevent a configuration change that would break the connection.
3. Select mode 6 on the front panel interface. See section 3.4 for information on selecting front panel
modes.
The terminal menu has the following features:
The terminal menu can be password protected to prevent unauthorised users for reading or
changing the radio configuration.
If a terminal menu is enabled, but there is no input for a configurable period of time, then the
terminal menu will disable itself. By default the terminal menu is disabled after 15 minutes.
Only 1 terminal menu can be available at any one time. This is done to prevent multiple users from
changing the configuration of a single radio at the same time.
The full terminal menu reference is provided in Appendix B.
