5.2 Front Panel Operation
The LCD will display one of five menus at any one time, these menus are:
1. STATUS (Prompt is S>)
2. TEST (Prompt is T>)
3. RATE (Prompt is R>)
4. OPTION (Prompt is O>)
5. CONFIG (Prompt is C>)
In normal circumstances, the front panel LCD will display a Status message relating to the overall state of
the data link e.g. READY. Additional status information may be displayed by scrolling down through the
menu. The Status menu is read - only. To select the next menu in the list the 'RIGHT MENU' button must
be pressed. To go back to a previous menu the 'LEFT MENU' button must be pressed. A prompt on the left
hand side of the display will indicate which menu has been selected. On entering a menu its title will be
displayed in full before the display reverts to the first menu item and the relevant prompt. If left in the
Status menu but not on the top line, the display will automatically time out and revert to the top line of
the status menu after 5 mins.
The sequencing through the menus is as follows:
* STATUS MENU *
** TEST MENU **
** RATE MENU **
* OPTION MENU *
* CONFIG MENU *
When scrolling through a menu, items will appear in the order detailed in the individual menu descriptions.
Each menu item display should indicate the current state of that item. For example if the loop back feature
was currently inactive then the display should read:
T > Loop back Off
To change a menu setting press the 'SELECT’ button. The display will change to reflect the modified status.
T > Loop back On
If a menu item is not appropriate for a given situation, it will not appear in the menu. For example, it is
not possible to have a loop back on and binary keys active at the same time. The first one selected will
therefore prevent the other from appearing in the menu. Any item selected in the Rate, Option, or
Configuration menus is automatically stored in non- volatile EEPROM memory. These features will thus be
restored when the BBM is next powered up. Items in the Test Menu are not stored and are lost on power
off.
