3.1.3 Data Entry 

Many RC3000 screens request some type of user input.  This section provides instructions on the entry of 
various types of data. 

When the user is prompted to select an action from a displayed list, pressing the numbered key 
corresponding to the desired action will initiate the action. 

When the user is prompted to scroll through a list of items, pressing the Scroll Up/Yes key will move 
forward through the list and pressing the Scroll Dn/No key will move backward through the list.  Pressing 
the Enter key when the desired item from the list is displayed will select the item. 

To manually enter the name of a satellite or location, the user scrolls through the list of  characters (A-Z, 
0-9 and blank) and selects the character by pressing the Enter key. To scroll forward through the list of 
characters use the 2/UP/N key and use the 8/DN/S key to scroll backward.   

Note: scrolling through the alphanumeric characters is not implemented via the Scroll Up/Yes or Scroll 
Dn/No keys since these keys will typically be used to move forward or backward through other fields from 
the field requiring alphanumeric input. 

After selecting one character, the flashing cursor is placed in the next space awaiting character selection.  
To complete the entry of the alphanumeric string, press Enter for a second time.  The user may backup 
through the string by using the BKSP key. 

To enter whole numbers, use the 0-9 keys to enter the desired numeric string followed by the Enter key.  
Note that the data field will initially show the current value for the item until numeric entry is started. To 
terminate the entry without changing the value, the user may use the Scroll Up/Yes or Scroll Dn/No key. 
The BKSP key may be used to move back in the string to correct the input.  When the input has been 
backed up past the first entry, the current value of the item will again be displayed.  Pressing the Enter 
key with the current value displayed will also result in no update.   

Entering floating point values is very similar to entering integer values except that the decimal point is 
inserted by using the (decimal pt.) Stop key. 

°56N) 

Entering Latitude or Longitude is similar to entering a floating point value but the decimal point is used to 
place the degree sign delimiter.  Following the degree sign, only values from 0 to 59 are valid since they 
represent minutes.  After entering the numeric value of latitude or longitude, the user is prompted to 
supply W(est) or E(ast) for longitude or N(orth) or S(outh) for latitude. 

This entry is similar to the degree/minute entry but allows decimal fractions of degrees.  This format will 
be used for satellite longitude entry where the degree/minute format is standard for vehicle position entry. 

Time is entered in HH:MM:SS format and date in DD/MM/YY format.
