Chapter 4 Operation
Command Mode
The operator may stop reading at any time by pressing any key other than the backspace
key on the hand-held terminal. Doing so will place the MMI in the Command mode,
where various operations are available. Stopping the reading process in this manner will
not affect any previously read transponders, and the Reading mode may be entered or
exited as often as necessary. All transponder data is stored in non-volatile memory which
protects valuable data from being lost in the event of main power loss. This also allows
the operator to quickly and easily pause the MMI while in the process of reading a route,
and resume reading the remainder of the route at a later time. While in command mode,
transponder interrogation is suspended.
The Command mode consists of the following main commands: Summary, Reading,
Tools, Quit, and Help. Each of these main commands have various sub-menus from
which to choose. On all Command mode menus the location of the menu squares on the
display roughly match their respective location on the keypad. Using the Summary menu
display in figure 5 as an example, the ALL menu selection would be chosen by pressing
the ‘0’ key on the handheld terminal. Each command is discussed in more detail in the
remainder of this section.
Summary Command
The Summary command menu is the invoked by pressing the ‘S’ key while in Reading
mode, or while the main Command mode menu is displayed. The six Summary command
menu selections display the total number of transponders having a particular status. As
an example, this information can be used to identify how many transponders have been
tampered with, then display each address so that a visual inspection of the transponder
may be performed.
