Detailed Operation

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.

Selection From List ( <0-9>SELECT )

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.

Scrolling Through List ( <SCR>THRU LIST )

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.

Alphanumeric Entry ( NAME:SATCOM K2 )

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.

Integer Data Entry ( SIZE: 240)

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.

Floating Point Data Entry (HEADING:180.0)

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.

Degree/Minute Latitude/Longitude Entry (TRUCK LAT:38°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.

Degree/Decimal Longitude Entry (SAT LON:179.0E)

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/Date

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