Front Panel Display Command (F) 

This command is used to set the front panel display of the Model 9840 to a desired 
combination of item and unit.  There are five subcommands: Front panel View (FV), Front 
panel Set (FS), Front panel Alternate(FA), Front panel pointer control to line 1 (F1), and 
Front panel pointer control to line 2 (F2) .   

The Front panel View (FV) command just tells you what is currently on the display, and 
what will be displayed when the View button on the front panel is pressed. 
 
Example: 
@123FV 
Acknowledge: 
@123 Active Display shows Load A in Lb  
     Other Display shows Peak A in Lb 

The Front panel Set (FS) command allows you to specify the item number and unit 
number for what is currently on the front panel display.  The format is FS (item 
number)(unit number), where the first item and unit numbers are 2 digits each and may 
be found using the question mark command (?). 
 
Example: 
@123FS0200 
Acknowledge: 
@123 Active Display shows Vall A in Lb  
     Other Display shows Peak A in Lb

The Front panel Alternate (FA) command allows you to switch between the currently 
displayed item and unit and the alternate item and unit just as if you had pressed the 
View button. 
 
Example: 
@123FA 
Acknowledge: 
@123 Active Display shows Peak A in Lb  
     Other Display shows Vall A in Lb

The Front Panel Pointer Control to Line 1 (F1) assigns the view pointer control to 
display line 1 (upper line of the display) and shows what is on the display.  This 
allows the operator to know which line will be configured or accessed.
