XPA200-7984-I-OPT1, X-Band SSPA System Operation
XPA200-7984-I-OPT1, Rev.2 3-9
3.3.1 SSPA commands
The SSPA commands are in a tree structured menu format
designed for access and execution of all control functions, and
to prevent the execution of an invalid entry by the operator.
When the prime power is turned on, the LCD display will contain a
message indicating the SSPA model number and the version number
of the firmware installed in the SSPA.
To select a Command Function press the "ENT" button on the
key-pad. The LCD display will indicate:
SELECT
CONFIGURATION MENU
This will provide the local operator access to the Command
Function Menus, which is the top level structure to start the
selection of Command Function Menus to input into the SSPA. To
sequence to the next Command Function Menu press a "DOWN" or "UP"
arrow button on the key-pad. The SSPA will step to the next
Command Function Menu each time a "DOWN" or "UP" arrow button is
pressed. The current Command Function Menu will be displayed on
the LCD display. The Command Function Menus are shown in Figure
3-1.
To select a specific Command Function Menu press the "ENT"
key-pad button. If a function is selected in error, press the
clear ("CLR") button which will return the SSPA to the main
command menus to allow the selection of another function. Any
one of the five Command Function Menus can be selected using this
procedure.
Once a Command Function has been selected, use the "RIGHT"
or "LEFT" arrow key-pad buttons to sequence through the Operating
Mode Commands. Each of the modes will be displayed on the LCD
display. A specific operating mode is selected by pressing the
"ENT" button. If an mode is selected in error, press the clear
("CLR") button which will return the SSPA to the operating menus
to allow the selection of another mode.
